Instant Access to Continuous Delivery in Java Essential Tools and Best Practices for Deploying Code to Production 1st Edition Daniel Bryant ebook Full Chapters
Forewords
There’s been broad agreement in the Continuous Delivery community
that tools don’t matter ever since Dave Farley and Jez Humble wrote
Continuous Delivery. There are plenty of good programming
languages out there, and plenty of good tools for building, testing,
and deploying your code to production. The wisdom of the crowd has
been: it doesn’t matter which tools you use, as long as you avoid the
really terrible tools.
This year, that wisdom has been augmented by the work of Dr. Nicole
Forsgren, Jez Humble, and Gene Kim. Their book Accelerate
summarises multiple years of research into Continuous Delivery and
IT performance. One of their conclusions is the ability for teams to
choose their own tools has a strong, statistical impact on Continuous
Delivery. So, now the wisdom of the crowd is: it doesn’t matter
which tools you use, as long as you’re able to choose them yourself
and you avoid the really terrible tools.
Take me, for example. The first time I did Continuous Delivery on a
team was at Elsevier in 2007. We built a journal website in Java 6,
Spring 2, and Tomcat 6 using XP practices like TDD and CI. The
pipeline was Ant and Cruise Control. The codebase was always
releasable, and once a week we deployed to production.
The first time I did Continuous Delivery across an entire company
was at LMAX in 2008. We built a state of the art financial exchange
in Java 6, Spring 3, and Resin 3 using XP practices and Domain
Driven Design. The pipeline was Ant and Cruise Control, with a lot
of custom dashboards. The codebase was always releasable, and once
a fortnight we deployed to production.
I’m sure you can see the similarities there. Groups of smart people
worked closely together. XP practices and sound design principles
were essential. The tools used were deliberately chosen for the task at
hand. And in the case of LMAX, it helped that the Head of
Development was writing the inaugural book on Continuous Delivery
at the time. I think his name was Dafydd, or Dev, or something.
What this all means is you can use Java, or PHP, or .NET, and
successfully implement Continuous Delivery. You can use Solaris
Zones, or Docker. You can use AWS, Azure, or that on-premises data
centre your Head Of Platform keeps saying is cheaper than AWS. Just
make sure you choose your tools yourself, for the particular problems
you face. And don’t use MKS for version control, QTP for testing, or
any commercial release management tool. They’re terrible.
So, if tools don’t matter for Continuous Delivery as long as you
choose them yourself and they’re not terrible choices, why am I
writing this foreword?
There’s actually a nuanced answer in here, if we look hard enough.
Tools don’t matter as much as the principles and practices of
Continuous Delivery, but they still matter a great deal. Programming
languages can help people to quickly create new features and defect
fixes, which reduces the Cost of Delay associated with product
development. Programming languages can also encourage a testable,
releasable application architecture, which are key enablers of
Continuous Delivery. Build, test, and deploy tooling can nudge
people in the right direction, towards practices such as TDD and
Trunk Based Development.
I was reminded of that nuance recently, when I cleared out my
childhood bedroom and found my university copy of Ivor Horton’s
Understanding Java 2. Java and I married each other in 1999, and
now it’s been so long we’ve both forgotten it’s our 20 year
anniversary very soon. In my opinion, it’s a great programming
language. Over the years Java, JUnit, Gradle, Spring and many other
tools have helped me to build well-tested, releasable applications, and
encourage people to adopt Continuous Delivery.
With Cloud, containerization, and Serverless leading our inexorable
march towards Skynet, we all need guidance from experienced
practitioners on how to use the latest tools and work towards
Continuous Delivery. In this book, Daniel and Abraham explain how
to use Java and popular tools such as Spring Boot, Kubernetes, and
AWS EKS to deliver modern web applications frequently enough to
meet market demand. IT practitioners working with Java and any of
the other tools mentioned in this book can rely on Daniel and
Abraham to explain how to implement a Continuous Delivery
toolchain for their applications.
Steve Smith
Continuous Delivery consultant at Continuous Delivery Consulting
Continuous delivery is one of the key practices that should be at the
heart of any engineering team. We have often been asked what are
some of the key enablers of success at jClarity and new build farm for
OpenJDK/Java at adoptopenjdk.net. The answer is that we can deploy
daily with the greatest of confidence, and do this with minimal
engineering teams. Ever since Dave Farley’s and Jez Humble’s
seminal Continuous Delivery: Reliable Software Releases through
Build, Test, and Deployment Automation (Addison-Wesley Signature)
came out in 2010, folks have started adopting continuous delivery
practices, but there has not been a comprehensive guide on how to do
this for the ~10 million Java developers out there. Well, now there is!
Daniel and Abraham are both real-world practitioners and their book
contains everything you need as a Java developer on this topic, with
in-depth explanations as to “why” you want to follow the practices of
continuous delivery; how to architect your application in a way that is
amenable to this; how to put together build, test, and deploy
pipelines; and also the intricacies of deploying to cloud and container
environments.
The impact of “cloud native” technologies on Java cannot be
understated—modern applications must now contend with such
concerns as connectivity to a larger number of external components
(both JVM and not), and a very different approach to handling
resources (such as I/O) that had traditionally been provided by the
local operating system. Even the life cycle of applications, and their
locality to specific machines, is changing, with approaches such as
immutable infrastructure and serverless requiring Java developers to
shift their thinking to take full advantage of the capabilities of these
new ways of delivering applications.
Within this brave new world, techniques such as continuous
deployment, the tooling and architectural thinking required to support
it, and the requirements of a cloud-centric local development
environment, are of paramount importance. Until now, there has been
no text that specifically caters to Java developers to guide them on
their journey into full adoption of continuous delivery and the
benefits it offers.

Preface
Why Did We Write This Book?
Both of us have been Java developers long enough to witness, and be
part of, several shifts within our chosen profession. Java the language
has evolved a long way since we both wrote our first lines of code:
Java 1.4 gave us nonblocking I/O, Java 8 gave us streams and
lambdas, Java 9 gave us modules, and Java 10 finally gave us local
variable type inference. Deployment platforms have also evolved in
leaps and bounds, and the emergence of cloud and containers has
provided many opportunities and challenges. One thing has not
changed, though, and that is the need to deliver value to end users and
customers. We have needed to use all of our skills, tools, and
practices as best as we could in order to make the delivery of
software as effective (and fun) as possible. Perhaps even more
importantly, we have needed to work with and lead our teams to share
this responsibility.
With an ever-increasing range of “best practices” emerging around
software development, architecture, and deployment platforms, there
is one thing that developers can generally agree on: the principles of
continuous integration and continuous delivery add enormous value
to the software delivery life cycle. With the increasing demands from
customers on the speed and stability of delivery, you need a
framework that provides fast feedback and enables the automation of
both quality assurance and the deployment processes. However, the
challenges for modern software developers are manyfold, and
attempting to introduce a methodology like continuous delivery—
which touches on all aspect of software design and delivery—means
that several new skills must be mastered, and some are typically
outside a developer’s existing comfort zone.
As our careers have progressed, we’ve frequently found ourselves
working on aspects of a project that used to be handled by other
individuals or teams, and as such we’ve learned the hard way the new
three key areas of developer skillsets that are needed to harness the
benefits of continuous delivery:
Architectural design
Correctly implementing the fundamentals of loose coupling and
high cohesion can have a dramatic effect on the ability to both
continually test and deploy components of a software system in
isolation.
Automated quality assurance
Business requirements for increased velocity, and the associated
architecture styles that have co-evolved with this (such as self-
contained systems, microservices, Function-as-a-Service, etc.),
mean that you are now typically testing distributed and complex
adaptive systems. These systems simply cannot be verified and
validated repeatedly and effectively using a traditional manual
process.
Deploying applications
The emergence of cloud and container technologies has
revolutionized deployment options for Java applications, and new
skills are needed for harnessing this and creating automated and
safe deployment and release processes.
This book distills our learning and offers guidance for mastering
these new skills.
Why You Should Read This Book
If you are a Java developer who wants to learn more about
continuous delivery, or are currently struggling with embracing this
way of delivering software, then this is the book for you. We have
provided not only the “how” and “what” of implementing the various
practices and tools associated with continuous delivery, but also the
“why.” We believe this is important, because if you understand the
motivations, you will be well placed to adapt particular practices that
don’t quite work for you as described. Understanding the reasoning
behind an approach also helps build strong foundations, and helps
you share and teach these ideas to others. As the Japanese poet
Matsuo Bashō said, “Do not seek to follow in the footsteps of the
wise; seek what they sought.”
We have also written this book as a call to action to you, as a Java
developer, to get outside your comfort zone and learn more about
architecture, automation, and operations. In the current software
development career space, we see increasingly fewer opportunities
for pure Java programming roles, with many new roles expecting
knowledge of continuous delivery, platforms, and operational tooling.
By investing in yourself and increasing your software development
knowledge and skills, you will not only be open to more
opportunities, but also become a better programmer.
As we wrote this book, we had no single idea of a prototypical reader
of this book, other than you being a Java developer, but one of the
following target personas may resonate with you:
Traditional enterprise Java developer
You have most likely been coding Java EE or Spring applications
for several years, and now you are realizing that new applications
within your organization are being designed around microservice-
style architectures, and the sysadmin or operations team is
experimenting with the cloud, Docker, and Kubernetes. You are
keen to learn more about how all these changes relate to building
Java applications, and you want to explore how automation will
make testing and deployment less painful.
Java developer looking to embrace DevOps
You have typically been developing Java applications for a few
years, and you have followed along with the blog posts, books,
and conference presentations that talk about the cloud, DevOps,
and Site Reliability Engineering (SRE). You may have envied the
development practices of organizations like Netflix, Google, or
Spotify, but you appreciate that not all the things they do are
relevant to you and your team. However, you are keen to learn
more and understand how you can embrace some of these ideas to
increasingly move to a DevOps style of working.
Recently graduated college or univerity student
You have just started your first professional software
development job, and although your time in formal education
provided you with many specific programming skills, you realize
that you aren’t sure how all the practices and tools join up for the
effective delivery of software. You want to learn more about the
entire software delivery process, filling in gaps in your
knowledge, and joining all of your skills together in order to
advance to the next level in your career.
What This Book Is Not
This book specifically emphasizes the complete approach to
implementing continuous delivery for Java applications, and as such,
it doesn’t contain a deep dive into everything related to architecture,
testing, or cloud technologies. Sure, you’ll learn the essentials of all
these subjects, but many of the chapter topics could be extended into
their own book, and we simply didn’t have the time or space to do
this. Whereas others have written books that are focused on specific
topics, we have attempted to reference and recommend their work.

THE CHURCH AND THE CENSUS.
I desire to say what follows, in all earnestness, to my fellow-
countrymen who have been, through God’s goodness, baptized into
the Church of England. I shall be thankful, also, if others will
patiently consider what is here set down.
There can be no question that, in old times, God was pleased to set
up a visible token, whereby the world might be convinced of His
power and love. And this token was also a witness to God’s Truth.
No one doubts that the Jewish Church and nation were the
witnesses of God; and that they were His witnesses by His own
express appointment. It is equally allowed, on all hands, that the
Jewish Church and nation failed in their witness. They failed—not
because the need of witnessing had been taken away; or their
authority to witness had been loosened. But they failed, because,
having the power of choice free—to stand by God or to desert Him,
they chose to desert Him. They failed, because they chose to blind
themselves to the need of witnessing. They failed, because they
chose to set at nought that authority to witness with which they had
been clothed. God’s law of always having His witness did not fail.
The very failure of the Jewish Church and nation, in the place of
witness, was a witness. The Jewish Church and nation could desert
its place of witness. It could prefer its own will to God’s will. It
could prefer the will of the people to the will of God. It could prefer
the kingdom of this world to the kingdom of Heaven. And it did
prefer its own will, and the will of the people, and the kingdom of
this world.
Look at the prophecy of Hosea, and what is there said of all Israel in
the name of Ephraim. Read the seventh chapter. The Prophet is
reproving the sins of the princes, and the great men of Israel. “All
their kings are fallen.” The flame of civil discord has spread, and
dried up the sources of legitimate authority among them. An
anarchy of eleven years, after the death of Jeroboam II., has
terminated in the assassination of Zachariah and his successors
Shallum and Pekahiah. “And yet there is none among them that
calleth unto Me,” saith the Lord.
And then, he denounces judgment against the people in the mass,
for their hypocrisy and unfaithfulness. Whereas, by God’s institution,
they were a peculiar people,—witnesses for God, and separate from
the world, “they have mixed themselves among the people,”—that is,
among the idolaters of the land,—they are “as a cake not turned,” as
a cake baked only on one side; serving God by halves, halting
between two masters; worshipping God a little, and worshipping
idols a little, and worshipping nothing much. And so, as a
consequence, what must have followed, did follow. The Syrians, in
the time of Jehoahaz, reduced them to great straits. They had but
fifty horsemen and ten chariots, and ten thousand footmen. [5]
They
were “made like the dust by threshing.” Shortly after, in the days of
Menahem, they became tributaries to Pul, king of Assyria. [6]
And at
length they were carried away captive bodily by Shalmaneser.
Now, all this has a forcible application to a spiritual state of things,
and sets forth the condition of the Church in the world, as at other
times, so especially at this time in which we live.
Ephraim is the witness of God—testifying God’s Truth,—bearing God’s
commission—appointed in the world to win and attract the people,—
to draw them upward, far above worldly measures of things to the
divine measure of things—to the things which shall be in the eternal
Future, and to the fixed and unchangeable will of God, on which that
eternal Future stands. But “Ephraim hath mixed himself” with the
people,—he has “learned their inventions,”—he has adapted his
witness to their demands,—he has lowered his standard of God’s
appointment to the people’s standard of human construction. So
that God’s teaching and man’s teaching have become confused and
indifferently accepted, and they who have fallen into grave errors of
faith are in no sense differently esteemed from those who have
maintained the truth as revealed by God, and as witnessed by the
Church in every land, in every age, by every tongue.
And so, the spiritual Ephraim, who was set up for a witness to the
truth, has become “a cake not turned,” a half-equipped soldier in the
fight, with but half a heart to his Master’s service.
What is the occasion which now presses? While many of us are
praising God in grateful love for His unspeakable mercy in
vouchsafing us His Truth—His determinate and fixed Truth—in which
alone souls are saved—His Truth, as divinely committed to the
Church “the pillar and ground of the Truth,”—and handed down from
age to age in every land,—His Truth as mercifully retained and
maintained in the Prayer Book of the Church of England,—set forth
with categorical precision in the three Creeds of universal
Christendom, and expanded and applied in the offices of Holy
Baptism and the Communion of the Body and Blood of Christ—while
we are keeping solemn festival to the Glory of God, and the power of
His Truth, the “religious world” is exciting itself with vexing hopes
and fears about the decennial Census which the State is about to
take of the religious condition of the country.
I do not believe that this question excites churchmen, or that they
care, except as a matter of political justice, what becomes of it. For
themselves they know what they are, and where they stand, and in
Whom they trust. And they are “ready always to give an answer to
every man that asketh them a reason of the hope that is in them.”
With no “uncertain sound,” or doubting heart, but with plainness and
boldness, as Christian men and women, “standing fast in one spirit,
with one mind striving together for the faith of the Gospel, and
nothing terrified by their adversaries.” [8]
But it is a question full of importance, because of the evidence which
it draws out of the condition of men’s minds among whom we live,
and because of the lesson which that evidence reads to ourselves.
I do not enter upon the question whether it is right or wrong for the
state to ask people about their religion. My own conviction is that,
under the distracting circumstances of religion in this country, it
would be better and wiser for the state to abstain. And yet in
common sense the state may as well demand information as to my
religious profession, as in respect of my age or worldly calling. But
the question having been raised, what is this evidence which it has
brought to light, and which I say is so grave in its results? There is
a vehement, almost a passionate resistance of the proposition, that
men should give an account of their faith.
It is true that Jesus Christ, the very Saviour and Redeemer of our
souls, has said, “Whosoever shall confess Me before men, him will I
confess also before My Father which is in heaven; and whosoever
shall deny Me before men, him will I also deny before My Father
which is in heaven.” [9a]
But people on all sides are saying, “not so—
not before men,—religion is a private and secret matter between
God and me.”
It is true that holy David declared that “he would speak even before
kings and not be ashamed,” [9b]
that S. John Baptist “confessed and
denied not, but confessed;” [9c]
that S. Paul, for himself, “continued
witnessing to small and great,” [10a]
and in the name of all Christians
laid it down that “we believe and therefore speak,” [10b]
and that
“every tongue should confess.” [10c]
But people on all sides are
saying, “Not so—not confess, not witness, not speak,—any other test
you please; number us as we sit here or stand there; but do not ask
us to speak. We prefer to take our place with the ‘chief rulers who
believed, but did not confess;’—we believe, but do not ask us to
confess.”
And this resistance has two sides—one political, and the other quasi-
religious.
Political men resist, because they say the Church of England holds
them, and yet does not hold them. It holds them politically, gives
them, if they demand it, baptism, or communion, or churching, or
burial. Yet it does not hold them because they object to her
services, and usages, and prefer preachers of their own, and other
doctrines than hers. “We are Churchmen,” say these people, “in one
sense, though not in another; and therefore we prefer not to define
ourselves at all. We go to ‘meeting,’ but we have not parted final
company with the Church. And as excommunication can alone sever
the bond between us, we are glad that excommunication is now
unknown.”
Such is one side of the opposition to the notion of defining their
faith. How shall they define it? Once perhaps when the Catechism
was fresh upon the soft and docile mind of their childhood they
might have been able, but now that is a mere reminiscence. They
know not to-day what they may believe to-morrow. Meantime they
will hold on to the Church as to a secular institution, and do what
they can to secularize it. It will become more useful and less
mischievous in their opinion, just as men cease to regard it as a
“witness” for the glory of God, and a training school for the salvation
of souls.
The other side of the same opposition has more appearance of
religious feeling about it. Men object to define their faith, because
really and conscientiously they have no faith which they can define.
“False shame,” “procrastination,” “self-distrust in honourable minds,”
(as it has been mischievously called, [11]
) “consciousness of
imperfection,” such are the pleas with which they indulgently flatter
themselves. They are not yet ripe for any “visible Church;” so they
ignorantly and complacently express it; they mean to wait; they are
not unchristian because they dare not make choice of a
denomination yet. Surely not. By and by will be time enough. They
will make a profession some day though not now.
When I hear on every side as I mix with my fellow men, and read in
every newspaper, as I strive to note down the voice of the public
press as it gains upon the popular mind, such sentiments as these, I
am bound to say that if this be not spiritually the reproduction of the
picture of Ephraim, as Hosea drew it in the days of Israel’s apostasy,
and as such, if it be not the accomplishment among ourselves of a
prophetic announcement which spiritually concerned the Church of
Christ, I know not where to find a prophecy fulfilled. “Ephraim he
hath mixed himself among the people: Ephraim is a cake not
turned. Strangers have devoured his strength, and he knoweth it
not; yea, grey hairs are here and there upon him; yet he knoweth
not.” [12]
I will now presume to say something in the presence of this calamity
which afflicts the Church of Christ in England.
I. First, I will say that as Truth is one and indivisible, so your faith
as English Churchmen, with the Cross of Christ upon your foreheads,
—and the bond of the “Apostles’ doctrine and fellowship” in your
hearts,—and the Prayer Book with its Catholic witness in your hands,
is fixed, and easily defined.
It is fixed, because otherwise it could not be the Truth. And you
possess that which is fixed, because otherwise that which you
possess could not be true. The Church of God is “the pillar and
ground of the Truth;” [13]
and you have the Truth from the Church of
God.
The Church of God does not create the Truth. The Church of God
does not even give force and power to the Truth. But the Church of
God is the depositary of the Truth. The Church of God has the Truth
to keep, and to maintain, and to hand down. The Church of God is
the orb, out of which the glorious light of the Truth shines and
overspreads the earth. The Church of God is the candlestick which
holds the light. The Church of God is the pillar on which the
proclamation of the Truth is written, and held up and heralded
through the world. You learn truth from that pillar. And that pillar is
the Church of God?
What Church of God? The one Holy Catholic and Apostolic Church of
God. The same which delivered the “decrees of the Apostles and
elders at Jerusalem:” [14]
the same which confounded Arius at
Nicæa: the same which overwhelmed Nestorius at Ephesus: the
same which silenced Macedonius at Constantinople: the same which
vanquished Eutyches at Chalcedon:—the one Holy Church
throughout the world.
2. Next, I desire to lay down this—that, contrary to what the
advocates of a religious census seem to imply—truth and numbers
have no relation one to the other, unless it be that truth is with the
few. The greatest number of mankind is yet in darkness and error;
as S. John says, “the world lieth in wickedness.”
All God’s Word testifies that, compared with the many who forsake
the truth, or who never accept it, or who deny it and lose its fruits,
those who receive it, and live by it, and enter into its reward, are
few. Of all the world at the time of the Flood only eight persons
were worthy to be rescued. Among all the guilty families in the
cities of the plain, only Lot’s escaped destruction. Of all the six
hundred thousand Hebrews delivered out of Egypt, though blessed
with the same miracles, conducted by the same Guide, and
nourished by the same Manna, two only entered the promised land.
In the taking of Jericho, of all the houses in the city only the harlot
Rahab’s was spared. Of all the thirty and two thousand soldiers of
Gideon, but three hundred were found worthy to contend for the
Lord. And so, of all those olive berries and clusters of grapes set
forth by the Prophet to describe the called of God,—there shall be
saved only “as the shaking of the olive tree, and as the gleaning
grapes, when the vintage is done.” [15]
Therefore Religion is not for show, but for reality. God is for Truth,
and not for numbers. And they who are truly wise must be content,
as the Apostles of old were content, to have numbers against them,
if so it be, and to pass in turn through good and evil report, in the
honest and simple defence of what is true.
This facing of the Truth against numbers is a necessity. And if you
seek to shun it, you are sure nevertheless to encounter it; and with
all the more roughness, for your efforts to escape it. If you side
with the multitude, you will probably be magnified by those who are
in the wrong. But you will hardly escape being censured by those
who are in the right. And their commendation, if it makes less
noise, has more value.
You must not be dismayed, therefore, because the world is against
you. You must not begin a course of action because it is popular;
nor must you abandon a course of action because it is decried. Look
to what pleases God, not to what will please the multitude. And
then you will do what is right. You will be wise for God. And God is
over all.
3. Once more. No earnest mind can entertain the thought of what
is passing among us, without feeling that these are sifting times.
Times of division, when errors abound, are always times of sifting;
times in which God is trying what men are made of; whether they
are corn or chaff, gold or dross, wheat or tares.
Ephraim is “a cake not turned.” But who are guilty? “I will sift the
House of Israel,” saith the Lord, “as corn is sifted in a sieve, yet shall
not the least grain fall upon the earth.” [17a]
This is the one comfort
in the midst of so much sorrow. Whosoever is true grain, shall not
be lost. See to it, then, that each soul among you is true grain.
God is sifting your sincerity by the errors which He suffers to
compass you about. “I hear there are divisions among you, and I
believe it,” says the Apostle, “for there must be heresies among you,
that they which are approved may be made manifest.” [17b]
And your
stability He is sifting—whether or not you are as Reuben, “unstable
as water,” weak, and soft, and yielding, and inconstant. And your
zeal, and your knowledge, and your love,—He is sifting all these, in
this your day of probation.
You have had great gifts at God’s Hand, unspeakable opportunities of
knowing Him and His Truth—the Word of God, the witness of the
Church, and the “Spirit leading you into all Truth” through the
ordained means of grace—through Sacraments and Prayer. How is it
with you? Are you yet “men” in knowledge, with the “full assurance
of understanding to the acknowledgment of the mystery of God, and
of the Father, and of Christ, in Whom are hid all the treasures of
wisdom and knowledge.” [18a]
Or are you “children in
understanding,” “tossed to and fro and carried about with every wind
of doctrine by the sleight of men, and cunning craftiness whereby
they lie in wait to deceive?” [18b]
Now is the test of your weakness or of your strength. Now it will be
seen who is possessed by that enervated and timid spirit which
inspires so many faltering hearts, and directs so many enfeebled
wills, in this day of conflict for the Church of God.
And, above all, your love is being sifted. Is your hold upon the
Church and her teaching “rooted and grounded in love?” God is
trying your love—your love to Himself, to Christ, to the Truth. The
head is not a casket in which Truth can safely lie enshrined. It is
soon stolen from thence. But, if you have lodged it in the heart, and
embedded it there in folds of love, men may take out your heart, but
out of your heart they cannot take the Truth.
It is for want of love that so many men among us are cowards,—
that so much is sacrificed to the first appearance of danger,—that so
much is offered up to expediency, to popularity, to success. The
world is a worshipper of success. But the world has no love for the
Truth. The world knows nothing of the blessed joy of undergoing
persecution and danger, and making ventures, for the Truth’s sake.
And so, as “Ephraim has mixed himself” with the world, he is as “a
cake not turned,” and “strangers have devoured his strength,” in this
age of concession and falling away.
But what says “He Who sitteth upon the throne?” “He that
overcometh shall inherit all things.” [19]
But the “fearful” or cowardly,
(the δειλοὶ,) and the unfaithful or “unbelieving” (the ἄπιστοι,) the
deserters who fall off from want of faith and patience, what of
them? “they shall have their part with murderers, and whore-
mongers, and idolaters, and liars, in the lake which burns with fire
and brimstone, which is the second death.” [20a]
And what says the Apostle? When love is perfect [20b]
then we have
“boldness in the crisis,” or judgment, or trial, of faith; and “love casts
out fear.” And fear is the parent of all unlawful concessions.
We owe the Truth an external service as well as an internal
devotion. And they have no love for the Truth who withhold an
external service. The faith of the heart will no more avail without
the confession of the mouth, than the confession of the mouth will
avail without the faith of the heart.
If it be enough for Christ that you know Him, though you confess
Him not before men, it will also be enough for you that He knows
you, though, at the last, He confess you not before men. It is not
enough to say, “I hold the Truth in my heart, but I am silent before
the world.” And, therefore, Christ does not say, “he that confesseth
Me in his heart;” but Christ says, “he that confesseth Me before
men.” They are vital words, these words of Christ. Lay them up in
your hearts, and live by them. Hear them at length. “Whosoever
shall confess Me before men, him will I confess also before My Father
Which is in Heaven. But whosoever shall deny Me before men, him
will I also deny before My Father Which is in Heaven. Think not that
I am come to send peace on earth, I came not to send peace but a
sword. For I am come to set a man at variance against his father,
and the daughter against her mother, and the daughter-in-law
against her mother-in-law, and a man’s foes shall be they of his own
household. He that loveth father or mother more than Me is not
worthy of Me; and he that loveth son or daughter more than Me is
not worthy of Me. And he that taketh not his cross and followeth
after Me is not worthy of Me. He that findeth his life shall lose it,
and he that loseth his life for My sake shall find it.” [21]
POSTSCRIPT.
While these pages are passing through the press, the Government
has yielded the point at issue. It has yielded, against its own
convictions. It has yielded to pressure,—and to pressure from those
whom it considers wrong-headed, and unreasonable, and unjust.
The Government believed and declared that it was fair, and right,
and just, and necessary “for legislative purposes,” that the people of
England should confess the religious profession which they make—
each man his own. The Government still believes in the fairness,
and justice, and necessity of such a declaration. But, because some
persons object to it, on the ground that no man ought to be asked
what his religion is, or whether he has any religion at all, and
because those persons have political influence, the Government has
yielded its convictions to those persons.
The Government loves its convictions a little. It loves political
influence much. And so, this has come out clear—whatever is just,
and fair, and right, and even necessary for “legislative purposes,” has
no chance of prevailing in the counsels of Government, unless, first,
the political influence of the Government shall be secured. If on the
side of injustice, and unfairness, and the entanglement and
perversion of legislation, there should be political influence, that will
be the side of the Government. Evil consequences in the future are
nothing. Present place and present power are everything.
I think this ought to be a lesson to Churchmen not to put faith in
Governments. The Church can never lose by any measures which
are just, and fair, and straightforward, and open. And, therefore, the
Church had nothing to lose from the “religious profession” clause of
the Census Bill. But as Governments do not bind themselves to keep
their faith, and are always ready to sacrifice their convictions of
justice to their lust of power, the Church must have no trust in
Governments.
The object of this tract is not affected by the weak and pitiful
conduct of the Government. It never was my object to defend the
“religious profession” clause. I have said that, considering the
religious distractions of this country, I think it would be wiser for the
Government to leave the religious profession of the people alone.
And I say so still. Never to have proposed a Census of religious
opinions at all would have been wise. But, to have proposed it—to
have stoutly maintained the justice of it—to have asserted the
necessity of it for equitable legislation,—and then, to have
withdrawn it to satisfy an unreasoning handful of Dissenters, who
make themselves heard in the House of Commons, is not to be
characterized by any negative form of judgment. This is not simply
want of wisdom. It is more like that moral imbecility which, in men
whom God has burdened with a high trust, is really a crime.
The object of this tract remains. And therefore, notwithstanding the
course which the Government has taken, I send it forth to effect that
object, as opportunity shall be found. I ask my countrymen and
countrywomen—Christian men and women—simply to consider, as in
the presence of God, these two appalling facts, which the discussion
of the Census Bill has forced to the surface, in this day of Crisis for
the Truth.
1. That thousands of baptized souls in England are content to
believe nothing in particular.
2. That thousands more who protest that they do believe something
in particular, protest also that they cannot “confess” that something
“before men.”

appear prominently whenever any copy of a Project Gutenberg™
work (any work on which the phrase “Project Gutenberg” appears,
or with which the phrase “Project Gutenberg” is associated) is
accessed, displayed, performed, viewed, copied or distributed:
This eBook is for the use of anyone anywhere in the United
States and most other parts of the world at no cost and with
almost no restrictions whatsoever. You may copy it, give it away

included with this eBook or online at www.gutenberg.org. If you
are not located in the United States, you will have to check the
laws of the country where you are located before using this
eBook.
1.E.2. If an individual Project Gutenberg™ electronic work is derived
from texts not protected by U.S. copyright law (does not contain a
notice indicating that it is posted with permission of the copyright
holder), the work can be copied and distributed to anyone in the
United States without paying any fees or charges. If you are
redistributing or providing access to a work with the phrase “Project
Gutenberg” associated with or appearing on the work, you must
comply either with the requirements of paragraphs 1.E.1 through
1.E.7 or obtain permission for the use of the work and the Project
Gutenberg™ trademark as set forth in paragraphs 1.E.8 or 1.E.9.
1.E.3. If an individual Project Gutenberg™ electronic work is posted
with the permission of the copyright holder, your use and distribution
must comply with both paragraphs 1.E.1 through 1.E.7 and any
additional terms imposed by the copyright holder. Additional terms
will be linked to the Project Gutenberg™ License for all works posted
with the permission of the copyright holder found at the beginning

electronic work, or any part of this electronic work, without
prominently displaying the sentence set forth in paragraph 1.E.1
with active links or immediate access to the full terms of the Project
Gutenberg™ License.
1.E.6. You may convert to and distribute this work in any binary,
compressed, marked up, nonproprietary or proprietary form,
including any word processing or hypertext form. However, if you
provide access to or distribute copies of a Project Gutenberg™ work
in a format other than “Plain Vanilla ASCII” or other format used in
the official version posted on the official Project Gutenberg™ website
(www.gutenberg.org), you must, at no additional cost, fee or
expense to the user, provide a copy, a means of exporting a copy, or
a means of obtaining a copy upon request, of the work in its original
“Plain Vanilla ASCII” or other form. Any alternate format must
include the full Project Gutenberg™ License as specified in
paragraph 1.E.1.
1.E.7. Do not charge a fee for access to, viewing, displaying,
performing, copying or distributing any Project Gutenberg™ works
unless you comply with paragraph 1.E.8 or 1.E.9.
1.E.8. You may charge a reasonable fee for copies of or providing
access to or distributing Project Gutenberg™ electronic works

fee is owed to the owner of the Project Gutenberg™ trademark,
but he has agreed to donate royalties under this paragraph to
the Project Gutenberg Literary Archive Foundation. Royalty
payments must be paid within 60 days following each date on
which you prepare (or are legally required to prepare) your
periodic tax returns. Royalty payments should be clearly marked
as such and sent to the Project Gutenberg Literary Archive
Foundation at the address specified in Section 4, “Information
about donations to the Project Gutenberg Literary Archive
Foundation.”
• You provide a full refund of any money paid by a user who
notifies you in writing (or by e-mail) within 30 days of receipt
that s/he does not agree to the terms of the full Project
Gutenberg™ License. You must require such a user to return or
destroy all copies of the works possessed in a physical medium
and discontinue all use of and all access to other copies of
Project Gutenberg™ works.

1.F.
1.F.1. Project Gutenberg volunteers and employees expend
considerable effort to identify, do copyright research on, transcribe
and proofread works not protected by U.S. copyright law in creating
the Project Gutenberg™ collection. Despite these efforts, Project
Gutenberg™ electronic works, and the medium on which they may
be stored, may contain “Defects,” such as, but not limited to,
incomplete, inaccurate or corrupt data, transcription errors, a
copyright or other intellectual property infringement, a defective or
damaged disk or other medium, a computer virus, or computer
codes that damage or cannot be read by your equipment.
1.F.2. LIMITED WARRANTY, DISCLAIMER OF DAMAGES - Except for
the “Right of Replacement or Refund” described in paragraph 1.F.3,
the Project Gutenberg Literary Archive Foundation, the owner of the
Project Gutenberg™ trademark, and any other party distributing a
Project Gutenberg™ electronic work under this agreement, disclaim
all liability to you for damages, costs and expenses, including legal
fees. YOU AGREE THAT YOU HAVE NO REMEDIES FOR
NEGLIGENCE, STRICT LIABILITY, BREACH OF WARRANTY OR
BREACH OF CONTRACT EXCEPT THOSE PROVIDED IN PARAGRAPH
1.F.3. YOU AGREE THAT THE FOUNDATION, THE TRADEMARK
OWNER, AND ANY DISTRIBUTOR UNDER THIS AGREEMENT WILL
NOT BE LIABLE TO YOU FOR ACTUAL, DIRECT, INDIRECT,
CONSEQUENTIAL, PUNITIVE OR INCIDENTAL DAMAGES EVEN IF
YOU GIVE NOTICE OF THE POSSIBILITY OF SUCH DAMAGE.
1.F.3. LIMITED RIGHT OF REPLACEMENT OR REFUND - If you
discover a defect in this electronic work within 90 days of receiving
it, you can receive a refund of the money (if any) you paid for it by
sending a written explanation to the person you received the work
from. If you received the work on a physical medium, you must
return the medium with your written explanation. The person or
entity that provided you with the defective work may elect to provide
a replacement copy in lieu of a refund. If you received the work
electronically, the person or entity providing it to you may choose to
give you a second opportunity to receive the work electronically in
lieu of a refund. If the second copy is also defective, you may
demand a refund in writing without further opportunities to fix the
problem.
1.F.4. Except for the limited right of replacement or refund set forth
in paragraph 1.F.3, this work is provided to you ‘AS-IS’, WITH NO
OTHER WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED,
INCLUDING BUT NOT LIMITED TO WARRANTIES OF
MERCHANTABILITY OR FITNESS FOR ANY PURPOSE.
1.F.5. Some states do not allow disclaimers of certain implied
warranties or the exclusion or limitation of certain types of damages.
If any disclaimer or limitation set forth in this agreement violates the
law of the state applicable to this agreement, the agreement shall be
interpreted to make the maximum disclaimer or limitation permitted
by the applicable state law. The invalidity or unenforceability of any
provision of this agreement shall not void the remaining provisions.
1.F.6. INDEMNITY - You agree to indemnify and hold the Foundation,
the trademark owner, any agent or employee of the Foundation,
anyone providing copies of Project Gutenberg™ electronic works in
accordance with this agreement, and any volunteers associated with
the production, promotion and distribution of Project Gutenberg™
electronic works, harmless from all liability, costs and expenses,
including legal fees, that arise directly or indirectly from any of the
following which you do or cause to occur: (a) distribution of this or
any Project Gutenberg™ work, (b) alteration, modification, or
additions or deletions to any Project Gutenberg™ work, and (c) any
Defect you cause.

  • 27. Forewords There’s been broad agreement in the Continuous Delivery community that tools don’t matter ever since Dave Farley and Jez Humble wrote Continuous Delivery. There are plenty of good programming languages out there, and plenty of good tools for building, testing, and deploying your code to production. The wisdom of the crowd has been: it doesn’t matter which tools you use, as long as you avoid the really terrible tools. This year, that wisdom has been augmented by the work of Dr. Nicole Forsgren, Jez Humble, and Gene Kim. Their book Accelerate summarises multiple years of research into Continuous Delivery and IT performance. One of their conclusions is the ability for teams to choose their own tools has a strong, statistical impact on Continuous Delivery. So, now the wisdom of the crowd is: it doesn’t matter which tools you use, as long as you’re able to choose them yourself and you avoid the really terrible tools. Take me, for example. The first time I did Continuous Delivery on a team was at Elsevier in 2007. We built a journal website in Java 6, Spring 2, and Tomcat 6 using XP practices like TDD and CI. The pipeline was Ant and Cruise Control. The codebase was always releasable, and once a week we deployed to production. The first time I did Continuous Delivery across an entire company was at LMAX in 2008. We built a state of the art financial exchange in Java 6, Spring 3, and Resin 3 using XP practices and Domain Driven Design. The pipeline was Ant and Cruise Control, with a lot
  • 28. of custom dashboards. The codebase was always releasable, and once a fortnight we deployed to production. I’m sure you can see the similarities there. Groups of smart people worked closely together. XP practices and sound design principles were essential. The tools used were deliberately chosen for the task at hand. And in the case of LMAX, it helped that the Head of Development was writing the inaugural book on Continuous Delivery at the time. I think his name was Dafydd, or Dev, or something. What this all means is you can use Java, or PHP, or .NET, and successfully implement Continuous Delivery. You can use Solaris Zones, or Docker. You can use AWS, Azure, or that on-premises data centre your Head Of Platform keeps saying is cheaper than AWS. Just make sure you choose your tools yourself, for the particular problems you face. And don’t use MKS for version control, QTP for testing, or any commercial release management tool. They’re terrible. So, if tools don’t matter for Continuous Delivery as long as you choose them yourself and they’re not terrible choices, why am I writing this foreword? There’s actually a nuanced answer in here, if we look hard enough. Tools don’t matter as much as the principles and practices of Continuous Delivery, but they still matter a great deal. Programming languages can help people to quickly create new features and defect fixes, which reduces the Cost of Delay associated with product development. Programming languages can also encourage a testable, releasable application architecture, which are key enablers of
  • 29. Continuous Delivery. Build, test, and deploy tooling can nudge people in the right direction, towards practices such as TDD and Trunk Based Development. I was reminded of that nuance recently, when I cleared out my childhood bedroom and found my university copy of Ivor Horton’s Understanding Java 2. Java and I married each other in 1999, and now it’s been so long we’ve both forgotten it’s our 20 year anniversary very soon. In my opinion, it’s a great programming language. Over the years Java, JUnit, Gradle, Spring and many other tools have helped me to build well-tested, releasable applications, and encourage people to adopt Continuous Delivery. With Cloud, containerization, and Serverless leading our inexorable march towards Skynet, we all need guidance from experienced practitioners on how to use the latest tools and work towards Continuous Delivery. In this book, Daniel and Abraham explain how to use Java and popular tools such as Spring Boot, Kubernetes, and AWS EKS to deliver modern web applications frequently enough to meet market demand. IT practitioners working with Java and any of the other tools mentioned in this book can rely on Daniel and Abraham to explain how to implement a Continuous Delivery toolchain for their applications. Steve Smith Continuous Delivery consultant at Continuous Delivery Consulting Continuous delivery is one of the key practices that should be at the heart of any engineering team. We have often been asked what are
  • 30. some of the key enablers of success at jClarity and new build farm for OpenJDK/Java at adoptopenjdk.net. The answer is that we can deploy daily with the greatest of confidence, and do this with minimal engineering teams. Ever since Dave Farley’s and Jez Humble’s seminal Continuous Delivery: Reliable Software Releases through Build, Test, and Deployment Automation (Addison-Wesley Signature) came out in 2010, folks have started adopting continuous delivery practices, but there has not been a comprehensive guide on how to do this for the ~10 million Java developers out there. Well, now there is! Daniel and Abraham are both real-world practitioners and their book contains everything you need as a Java developer on this topic, with in-depth explanations as to “why” you want to follow the practices of continuous delivery; how to architect your application in a way that is amenable to this; how to put together build, test, and deploy pipelines; and also the intricacies of deploying to cloud and container environments. The impact of “cloud native” technologies on Java cannot be understated—modern applications must now contend with such concerns as connectivity to a larger number of external components (both JVM and not), and a very different approach to handling resources (such as I/O) that had traditionally been provided by the local operating system. Even the life cycle of applications, and their locality to specific machines, is changing, with approaches such as immutable infrastructure and serverless requiring Java developers to shift their thinking to take full advantage of the capabilities of these new ways of delivering applications.
  • 31. Within this brave new world, techniques such as continuous deployment, the tooling and architectural thinking required to support it, and the requirements of a cloud-centric local development environment, are of paramount importance. Until now, there has been no text that specifically caters to Java developers to guide them on their journey into full adoption of continuous delivery and the benefits it offers. Martijn Verburg, CEO at jClarity and LJC Leader — Ben Evans, Author and Consulting CTO
  • 32. Preface Why Did We Write This Book? Both of us have been Java developers long enough to witness, and be part of, several shifts within our chosen profession. Java the language has evolved a long way since we both wrote our first lines of code: Java 1.4 gave us nonblocking I/O, Java 8 gave us streams and lambdas, Java 9 gave us modules, and Java 10 finally gave us local variable type inference. Deployment platforms have also evolved in leaps and bounds, and the emergence of cloud and containers has provided many opportunities and challenges. One thing has not changed, though, and that is the need to deliver value to end users and customers. We have needed to use all of our skills, tools, and practices as best as we could in order to make the delivery of software as effective (and fun) as possible. Perhaps even more importantly, we have needed to work with and lead our teams to share this responsibility. With an ever-increasing range of “best practices” emerging around software development, architecture, and deployment platforms, there is one thing that developers can generally agree on: the principles of continuous integration and continuous delivery add enormous value to the software delivery life cycle. With the increasing demands from customers on the speed and stability of delivery, you need a framework that provides fast feedback and enables the automation of
  • 33. both quality assurance and the deployment processes. However, the challenges for modern software developers are manyfold, and attempting to introduce a methodology like continuous delivery— which touches on all aspect of software design and delivery—means that several new skills must be mastered, and some are typically outside a developer’s existing comfort zone. As our careers have progressed, we’ve frequently found ourselves working on aspects of a project that used to be handled by other individuals or teams, and as such we’ve learned the hard way the new three key areas of developer skillsets that are needed to harness the benefits of continuous delivery: Architectural design Correctly implementing the fundamentals of loose coupling and high cohesion can have a dramatic effect on the ability to both continually test and deploy components of a software system in isolation. Automated quality assurance Business requirements for increased velocity, and the associated architecture styles that have co-evolved with this (such as self- contained systems, microservices, Function-as-a-Service, etc.), mean that you are now typically testing distributed and complex adaptive systems. These systems simply cannot be verified and validated repeatedly and effectively using a traditional manual process. Deploying applications The emergence of cloud and container technologies has revolutionized deployment options for Java applications, and new skills are needed for harnessing this and creating automated and safe deployment and release processes.
  • 34. This book distills our learning and offers guidance for mastering these new skills. Why You Should Read This Book If you are a Java developer who wants to learn more about continuous delivery, or are currently struggling with embracing this way of delivering software, then this is the book for you. We have provided not only the “how” and “what” of implementing the various practices and tools associated with continuous delivery, but also the “why.” We believe this is important, because if you understand the motivations, you will be well placed to adapt particular practices that don’t quite work for you as described. Understanding the reasoning behind an approach also helps build strong foundations, and helps you share and teach these ideas to others. As the Japanese poet Matsuo Bashō said, “Do not seek to follow in the footsteps of the wise; seek what they sought.” We have also written this book as a call to action to you, as a Java developer, to get outside your comfort zone and learn more about architecture, automation, and operations. In the current software development career space, we see increasingly fewer opportunities for pure Java programming roles, with many new roles expecting knowledge of continuous delivery, platforms, and operational tooling. By investing in yourself and increasing your software development knowledge and skills, you will not only be open to more opportunities, but also become a better programmer.
  • 35. As we wrote this book, we had no single idea of a prototypical reader of this book, other than you being a Java developer, but one of the following target personas may resonate with you: Traditional enterprise Java developer You have most likely been coding Java EE or Spring applications for several years, and now you are realizing that new applications within your organization are being designed around microservice- style architectures, and the sysadmin or operations team is experimenting with the cloud, Docker, and Kubernetes. You are keen to learn more about how all these changes relate to building Java applications, and you want to explore how automation will make testing and deployment less painful. Java developer looking to embrace DevOps You have typically been developing Java applications for a few years, and you have followed along with the blog posts, books, and conference presentations that talk about the cloud, DevOps, and Site Reliability Engineering (SRE). You may have envied the development practices of organizations like Netflix, Google, or Spotify, but you appreciate that not all the things they do are relevant to you and your team. However, you are keen to learn more and understand how you can embrace some of these ideas to increasingly move to a DevOps style of working. Recently graduated college or univerity student You have just started your first professional software development job, and although your time in formal education provided you with many specific programming skills, you realize that you aren’t sure how all the practices and tools join up for the effective delivery of software. You want to learn more about the entire software delivery process, filling in gaps in your knowledge, and joining all of your skills together in order to advance to the next level in your career.
  • 36. What This Book Is Not This book specifically emphasizes the complete approach to implementing continuous delivery for Java applications, and as such, it doesn’t contain a deep dive into everything related to architecture, testing, or cloud technologies. Sure, you’ll learn the essentials of all these subjects, but many of the chapter topics could be extended into their own book, and we simply didn’t have the time or space to do this. Whereas others have written books that are focused on specific topics, we have attempted to reference and recommend their work.

  • 47. THE CHURCH AND THE CENSUS. I desire to say what follows, in all earnestness, to my fellow- countrymen who have been, through God’s goodness, baptized into the Church of England. I shall be thankful, also, if others will patiently consider what is here set down. There can be no question that, in old times, God was pleased to set up a visible token, whereby the world might be convinced of His power and love. And this token was also a witness to God’s Truth. No one doubts that the Jewish Church and nation were the witnesses of God; and that they were His witnesses by His own express appointment. It is equally allowed, on all hands, that the Jewish Church and nation failed in their witness. They failed—not because the need of witnessing had been taken away; or their authority to witness had been loosened. But they failed, because, having the power of choice free—to stand by God or to desert Him, they chose to desert Him. They failed, because they chose to blind themselves to the need of witnessing. They failed, because they chose to set at nought that authority to witness with which they had been clothed. God’s law of always having His witness did not fail. The very failure of the Jewish Church and nation, in the place of witness, was a witness. The Jewish Church and nation could desert its place of witness. It could prefer its own will to God’s will. It could prefer the will of the people to the will of God. It could prefer the kingdom of this world to the kingdom of Heaven. And it did prefer its own will, and the will of the people, and the kingdom of this world.
  • 48. Look at the prophecy of Hosea, and what is there said of all Israel in the name of Ephraim. Read the seventh chapter. The Prophet is reproving the sins of the princes, and the great men of Israel. “All their kings are fallen.” The flame of civil discord has spread, and dried up the sources of legitimate authority among them. An anarchy of eleven years, after the death of Jeroboam II., has terminated in the assassination of Zachariah and his successors Shallum and Pekahiah. “And yet there is none among them that calleth unto Me,” saith the Lord. And then, he denounces judgment against the people in the mass, for their hypocrisy and unfaithfulness. Whereas, by God’s institution, they were a peculiar people,—witnesses for God, and separate from the world, “they have mixed themselves among the people,”—that is, among the idolaters of the land,—they are “as a cake not turned,” as a cake baked only on one side; serving God by halves, halting between two masters; worshipping God a little, and worshipping idols a little, and worshipping nothing much. And so, as a consequence, what must have followed, did follow. The Syrians, in the time of Jehoahaz, reduced them to great straits. They had but fifty horsemen and ten chariots, and ten thousand footmen. [5] They were “made like the dust by threshing.” Shortly after, in the days of Menahem, they became tributaries to Pul, king of Assyria. [6] And at length they were carried away captive bodily by Shalmaneser. Now, all this has a forcible application to a spiritual state of things, and sets forth the condition of the Church in the world, as at other times, so especially at this time in which we live. Ephraim is the witness of God—testifying God’s Truth,—bearing God’s commission—appointed in the world to win and attract the people,— to draw them upward, far above worldly measures of things to the divine measure of things—to the things which shall be in the eternal Future, and to the fixed and unchangeable will of God, on which that eternal Future stands. But “Ephraim hath mixed himself” with the people,—he has “learned their inventions,”—he has adapted his witness to their demands,—he has lowered his standard of God’s
  • 49. appointment to the people’s standard of human construction. So that God’s teaching and man’s teaching have become confused and indifferently accepted, and they who have fallen into grave errors of faith are in no sense differently esteemed from those who have maintained the truth as revealed by God, and as witnessed by the Church in every land, in every age, by every tongue. And so, the spiritual Ephraim, who was set up for a witness to the truth, has become “a cake not turned,” a half-equipped soldier in the fight, with but half a heart to his Master’s service. What is the occasion which now presses? While many of us are praising God in grateful love for His unspeakable mercy in vouchsafing us His Truth—His determinate and fixed Truth—in which alone souls are saved—His Truth, as divinely committed to the Church “the pillar and ground of the Truth,”—and handed down from age to age in every land,—His Truth as mercifully retained and maintained in the Prayer Book of the Church of England,—set forth with categorical precision in the three Creeds of universal Christendom, and expanded and applied in the offices of Holy Baptism and the Communion of the Body and Blood of Christ—while we are keeping solemn festival to the Glory of God, and the power of His Truth, the “religious world” is exciting itself with vexing hopes and fears about the decennial Census which the State is about to take of the religious condition of the country. I do not believe that this question excites churchmen, or that they care, except as a matter of political justice, what becomes of it. For themselves they know what they are, and where they stand, and in Whom they trust. And they are “ready always to give an answer to every man that asketh them a reason of the hope that is in them.” With no “uncertain sound,” or doubting heart, but with plainness and boldness, as Christian men and women, “standing fast in one spirit, with one mind striving together for the faith of the Gospel, and nothing terrified by their adversaries.” [8]
  • 50. But it is a question full of importance, because of the evidence which it draws out of the condition of men’s minds among whom we live, and because of the lesson which that evidence reads to ourselves. I do not enter upon the question whether it is right or wrong for the state to ask people about their religion. My own conviction is that, under the distracting circumstances of religion in this country, it would be better and wiser for the state to abstain. And yet in common sense the state may as well demand information as to my religious profession, as in respect of my age or worldly calling. But the question having been raised, what is this evidence which it has brought to light, and which I say is so grave in its results? There is a vehement, almost a passionate resistance of the proposition, that men should give an account of their faith. It is true that Jesus Christ, the very Saviour and Redeemer of our souls, has said, “Whosoever shall confess Me before men, him will I confess also before My Father which is in heaven; and whosoever shall deny Me before men, him will I also deny before My Father which is in heaven.” [9a] But people on all sides are saying, “not so— not before men,—religion is a private and secret matter between God and me.” It is true that holy David declared that “he would speak even before kings and not be ashamed,” [9b] that S. John Baptist “confessed and denied not, but confessed;” [9c] that S. Paul, for himself, “continued witnessing to small and great,” [10a] and in the name of all Christians laid it down that “we believe and therefore speak,” [10b] and that “every tongue should confess.” [10c] But people on all sides are saying, “Not so—not confess, not witness, not speak,—any other test you please; number us as we sit here or stand there; but do not ask us to speak. We prefer to take our place with the ‘chief rulers who believed, but did not confess;’—we believe, but do not ask us to confess.” And this resistance has two sides—one political, and the other quasi- religious.
  • 51. Political men resist, because they say the Church of England holds them, and yet does not hold them. It holds them politically, gives them, if they demand it, baptism, or communion, or churching, or burial. Yet it does not hold them because they object to her services, and usages, and prefer preachers of their own, and other doctrines than hers. “We are Churchmen,” say these people, “in one sense, though not in another; and therefore we prefer not to define ourselves at all. We go to ‘meeting,’ but we have not parted final company with the Church. And as excommunication can alone sever the bond between us, we are glad that excommunication is now unknown.” Such is one side of the opposition to the notion of defining their faith. How shall they define it? Once perhaps when the Catechism was fresh upon the soft and docile mind of their childhood they might have been able, but now that is a mere reminiscence. They know not to-day what they may believe to-morrow. Meantime they will hold on to the Church as to a secular institution, and do what they can to secularize it. It will become more useful and less mischievous in their opinion, just as men cease to regard it as a “witness” for the glory of God, and a training school for the salvation of souls. The other side of the same opposition has more appearance of religious feeling about it. Men object to define their faith, because really and conscientiously they have no faith which they can define. “False shame,” “procrastination,” “self-distrust in honourable minds,” (as it has been mischievously called, [11] ) “consciousness of imperfection,” such are the pleas with which they indulgently flatter themselves. They are not yet ripe for any “visible Church;” so they ignorantly and complacently express it; they mean to wait; they are not unchristian because they dare not make choice of a denomination yet. Surely not. By and by will be time enough. They will make a profession some day though not now. When I hear on every side as I mix with my fellow men, and read in every newspaper, as I strive to note down the voice of the public
  • 52. press as it gains upon the popular mind, such sentiments as these, I am bound to say that if this be not spiritually the reproduction of the picture of Ephraim, as Hosea drew it in the days of Israel’s apostasy, and as such, if it be not the accomplishment among ourselves of a prophetic announcement which spiritually concerned the Church of Christ, I know not where to find a prophecy fulfilled. “Ephraim he hath mixed himself among the people: Ephraim is a cake not turned. Strangers have devoured his strength, and he knoweth it not; yea, grey hairs are here and there upon him; yet he knoweth not.” [12] I will now presume to say something in the presence of this calamity which afflicts the Church of Christ in England. I. First, I will say that as Truth is one and indivisible, so your faith as English Churchmen, with the Cross of Christ upon your foreheads, —and the bond of the “Apostles’ doctrine and fellowship” in your hearts,—and the Prayer Book with its Catholic witness in your hands, is fixed, and easily defined. It is fixed, because otherwise it could not be the Truth. And you possess that which is fixed, because otherwise that which you possess could not be true. The Church of God is “the pillar and ground of the Truth;” [13] and you have the Truth from the Church of God. The Church of God does not create the Truth. The Church of God does not even give force and power to the Truth. But the Church of God is the depositary of the Truth. The Church of God has the Truth to keep, and to maintain, and to hand down. The Church of God is the orb, out of which the glorious light of the Truth shines and overspreads the earth. The Church of God is the candlestick which holds the light. The Church of God is the pillar on which the proclamation of the Truth is written, and held up and heralded through the world. You learn truth from that pillar. And that pillar is the Church of God?
  • 53. What Church of God? The one Holy Catholic and Apostolic Church of God. The same which delivered the “decrees of the Apostles and elders at Jerusalem:” [14] the same which confounded Arius at Nicæa: the same which overwhelmed Nestorius at Ephesus: the same which silenced Macedonius at Constantinople: the same which vanquished Eutyches at Chalcedon:—the one Holy Church throughout the world. 2. Next, I desire to lay down this—that, contrary to what the advocates of a religious census seem to imply—truth and numbers have no relation one to the other, unless it be that truth is with the few. The greatest number of mankind is yet in darkness and error; as S. John says, “the world lieth in wickedness.” All God’s Word testifies that, compared with the many who forsake the truth, or who never accept it, or who deny it and lose its fruits, those who receive it, and live by it, and enter into its reward, are few. Of all the world at the time of the Flood only eight persons were worthy to be rescued. Among all the guilty families in the cities of the plain, only Lot’s escaped destruction. Of all the six hundred thousand Hebrews delivered out of Egypt, though blessed with the same miracles, conducted by the same Guide, and nourished by the same Manna, two only entered the promised land. In the taking of Jericho, of all the houses in the city only the harlot Rahab’s was spared. Of all the thirty and two thousand soldiers of Gideon, but three hundred were found worthy to contend for the Lord. And so, of all those olive berries and clusters of grapes set forth by the Prophet to describe the called of God,—there shall be saved only “as the shaking of the olive tree, and as the gleaning grapes, when the vintage is done.” [15] Therefore Religion is not for show, but for reality. God is for Truth, and not for numbers. And they who are truly wise must be content, as the Apostles of old were content, to have numbers against them, if so it be, and to pass in turn through good and evil report, in the honest and simple defence of what is true.
  • 54. This facing of the Truth against numbers is a necessity. And if you seek to shun it, you are sure nevertheless to encounter it; and with all the more roughness, for your efforts to escape it. If you side with the multitude, you will probably be magnified by those who are in the wrong. But you will hardly escape being censured by those who are in the right. And their commendation, if it makes less noise, has more value. You must not be dismayed, therefore, because the world is against you. You must not begin a course of action because it is popular; nor must you abandon a course of action because it is decried. Look to what pleases God, not to what will please the multitude. And then you will do what is right. You will be wise for God. And God is over all. 3. Once more. No earnest mind can entertain the thought of what is passing among us, without feeling that these are sifting times. Times of division, when errors abound, are always times of sifting; times in which God is trying what men are made of; whether they are corn or chaff, gold or dross, wheat or tares. Ephraim is “a cake not turned.” But who are guilty? “I will sift the House of Israel,” saith the Lord, “as corn is sifted in a sieve, yet shall not the least grain fall upon the earth.” [17a] This is the one comfort in the midst of so much sorrow. Whosoever is true grain, shall not be lost. See to it, then, that each soul among you is true grain. God is sifting your sincerity by the errors which He suffers to compass you about. “I hear there are divisions among you, and I believe it,” says the Apostle, “for there must be heresies among you, that they which are approved may be made manifest.” [17b] And your stability He is sifting—whether or not you are as Reuben, “unstable as water,” weak, and soft, and yielding, and inconstant. And your zeal, and your knowledge, and your love,—He is sifting all these, in this your day of probation.
  • 55. You have had great gifts at God’s Hand, unspeakable opportunities of knowing Him and His Truth—the Word of God, the witness of the Church, and the “Spirit leading you into all Truth” through the ordained means of grace—through Sacraments and Prayer. How is it with you? Are you yet “men” in knowledge, with the “full assurance of understanding to the acknowledgment of the mystery of God, and of the Father, and of Christ, in Whom are hid all the treasures of wisdom and knowledge.” [18a] Or are you “children in understanding,” “tossed to and fro and carried about with every wind of doctrine by the sleight of men, and cunning craftiness whereby they lie in wait to deceive?” [18b] Now is the test of your weakness or of your strength. Now it will be seen who is possessed by that enervated and timid spirit which inspires so many faltering hearts, and directs so many enfeebled wills, in this day of conflict for the Church of God. And, above all, your love is being sifted. Is your hold upon the Church and her teaching “rooted and grounded in love?” God is trying your love—your love to Himself, to Christ, to the Truth. The head is not a casket in which Truth can safely lie enshrined. It is soon stolen from thence. But, if you have lodged it in the heart, and embedded it there in folds of love, men may take out your heart, but out of your heart they cannot take the Truth. It is for want of love that so many men among us are cowards,— that so much is sacrificed to the first appearance of danger,—that so much is offered up to expediency, to popularity, to success. The world is a worshipper of success. But the world has no love for the Truth. The world knows nothing of the blessed joy of undergoing persecution and danger, and making ventures, for the Truth’s sake. And so, as “Ephraim has mixed himself” with the world, he is as “a cake not turned,” and “strangers have devoured his strength,” in this age of concession and falling away. But what says “He Who sitteth upon the throne?” “He that overcometh shall inherit all things.” [19] But the “fearful” or cowardly,
  • 56. (the δειλοὶ,) and the unfaithful or “unbelieving” (the ἄπιστοι,) the deserters who fall off from want of faith and patience, what of them? “they shall have their part with murderers, and whore- mongers, and idolaters, and liars, in the lake which burns with fire and brimstone, which is the second death.” [20a] And what says the Apostle? When love is perfect [20b] then we have “boldness in the crisis,” or judgment, or trial, of faith; and “love casts out fear.” And fear is the parent of all unlawful concessions. We owe the Truth an external service as well as an internal devotion. And they have no love for the Truth who withhold an external service. The faith of the heart will no more avail without the confession of the mouth, than the confession of the mouth will avail without the faith of the heart. If it be enough for Christ that you know Him, though you confess Him not before men, it will also be enough for you that He knows you, though, at the last, He confess you not before men. It is not enough to say, “I hold the Truth in my heart, but I am silent before the world.” And, therefore, Christ does not say, “he that confesseth Me in his heart;” but Christ says, “he that confesseth Me before men.” They are vital words, these words of Christ. Lay them up in your hearts, and live by them. Hear them at length. “Whosoever shall confess Me before men, him will I confess also before My Father Which is in Heaven. But whosoever shall deny Me before men, him will I also deny before My Father Which is in Heaven. Think not that I am come to send peace on earth, I came not to send peace but a sword. For I am come to set a man at variance against his father, and the daughter against her mother, and the daughter-in-law against her mother-in-law, and a man’s foes shall be they of his own household. He that loveth father or mother more than Me is not worthy of Me; and he that loveth son or daughter more than Me is not worthy of Me. And he that taketh not his cross and followeth after Me is not worthy of Me. He that findeth his life shall lose it, and he that loseth his life for My sake shall find it.” [21]
  • 57. POSTSCRIPT. While these pages are passing through the press, the Government has yielded the point at issue. It has yielded, against its own convictions. It has yielded to pressure,—and to pressure from those whom it considers wrong-headed, and unreasonable, and unjust. The Government believed and declared that it was fair, and right, and just, and necessary “for legislative purposes,” that the people of England should confess the religious profession which they make— each man his own. The Government still believes in the fairness, and justice, and necessity of such a declaration. But, because some persons object to it, on the ground that no man ought to be asked what his religion is, or whether he has any religion at all, and because those persons have political influence, the Government has yielded its convictions to those persons. The Government loves its convictions a little. It loves political influence much. And so, this has come out clear—whatever is just, and fair, and right, and even necessary for “legislative purposes,” has no chance of prevailing in the counsels of Government, unless, first, the political influence of the Government shall be secured. If on the side of injustice, and unfairness, and the entanglement and perversion of legislation, there should be political influence, that will be the side of the Government. Evil consequences in the future are nothing. Present place and present power are everything. I think this ought to be a lesson to Churchmen not to put faith in Governments. The Church can never lose by any measures which are just, and fair, and straightforward, and open. And, therefore, the
  • 58. Church had nothing to lose from the “religious profession” clause of the Census Bill. But as Governments do not bind themselves to keep their faith, and are always ready to sacrifice their convictions of justice to their lust of power, the Church must have no trust in Governments. The object of this tract is not affected by the weak and pitiful conduct of the Government. It never was my object to defend the “religious profession” clause. I have said that, considering the religious distractions of this country, I think it would be wiser for the Government to leave the religious profession of the people alone. And I say so still. Never to have proposed a Census of religious opinions at all would have been wise. But, to have proposed it—to have stoutly maintained the justice of it—to have asserted the necessity of it for equitable legislation,—and then, to have withdrawn it to satisfy an unreasoning handful of Dissenters, who make themselves heard in the House of Commons, is not to be characterized by any negative form of judgment. This is not simply want of wisdom. It is more like that moral imbecility which, in men whom God has burdened with a high trust, is really a crime. The object of this tract remains. And therefore, notwithstanding the course which the Government has taken, I send it forth to effect that object, as opportunity shall be found. I ask my countrymen and countrywomen—Christian men and women—simply to consider, as in the presence of God, these two appalling facts, which the discussion of the Census Bill has forced to the surface, in this day of Crisis for the Truth. 1. That thousands of baptized souls in England are content to believe nothing in particular. 2. That thousands more who protest that they do believe something in particular, protest also that they cannot “confess” that something “before men.”
