It is popular for current churches to make their statement of faith as vague a possible. While it is understandable in making big tents, it seems disingenuous to conceal a product before selling it. A genuine church sells one product, Jesus Christ as portrayed by the Bible. It is a belief system involving the four branches of philosophy (Epistemology, Metaphysics, Ethics, and Categorical Philosophy), more specifically, the ten doctrines of the Systematic Theology (Bibliology, Theology Proper, Christology, Pneumatology, Angelology, Anthropology, Hamartiology, Soteriology, Ecclesiology, and Eschatology). This series is systematic theology in a nutshell (on “what we believe” in the state of faith), plus some apologetics (on “why we believe so”).
