Unity Statement

In essentials unity, in nonessentials liberty, in all things charity. The Christian Apologetics Alliance (CAA) is united in our Statement of Faith. The CAA does not, as an organization, have positions on many of the doctrinal or theological debates that take place within the church. Our primary concern is to promote the gracious, rational defense of the central claims of Christianity and the critique of opposing systems of thought. The CAA joyfully welcomes Catholic, Eastern Orthodox, and diverse Protestant believers, and we are committed to treating all these traditions with respect in our community.
