The following outline is provided as an overview of and topical guide to religion:
Religion – organized collection of beliefs, cultural systems, and world views that relate humanity to an order of existence. Many religions have narratives, symbols, and sacred histories that are intended to explain the meaning of life and/or to explain the origin of life or the Universe. From their beliefs about the cosmos and human nature, people derive morality, ethics, religious laws or a preferred lifestyle.
Theology is the study of religious belief from a religious perspective, with a focus on the nature of divinity and the history behind religion. It is taught as an academic discipline, typically in universities and seminaries. It occupies itself with the unique content of analyzing the supernatural, but also deals with religious epistemology, asks and seeks to answer the question of revelation. Revelation pertains to the acceptance of God, gods, or deities, as not only transcendent or above the natural world, but also willing and able to interact with the natural world and to reveal themselves to humankind.
Theologians use various forms of analysis and argument (experiential, philosophical, ethnographic, historical, and others) to help understand, explain, test, critique, defend or promote any myriad of religious topics. As in philosophy of ethics and case law, arguments often assume the existence of previously resolved questions, and develop by making analogies from them to draw new inferences in new situations.
