The structure of religion includes various components such as theologies, creeds, rituals, sects, symbols and sacred literature. Theologies are systematic explanations of a religion's beliefs regarding the relationship between God and the universe. Creeds represent the codified set of doctrines of a religious group. Rituals are standardized religious practices and ceremonies that are performed for various purposes like communicating with the supernatural. Sects are religious groups that split off from larger denominations due to doctrinal or other differences. Symbols represent religious groups and concepts. Sacred literature includes religious texts that outline the theological principles and beliefs of a faith.
