Some religious traditions do a better job of keeping their history alive than others. While being reminded of every significant activity that ever happened on a particular date strikes me as perhaps oppressive, I really am having problems with the ahistoricism of the church I nominally attend.
Honestly — our take on the Gospels goes back to at least 1541. Surely there’s been some interesting thinking that could filter into a sermon every so often. I’m sure there a few complicated things you had to study in your theology and homiletics courses back in seminary. PICK ONE! Because if I only get to hear your personal insights from the week, I’m not part of a tradition, I’m part of a studio audience.
