Why we ask this
These six points are not a test of how much theology someone knows. They are the things Christians have agreed on since the earliest centuries of the church, and they are the shortest honest answer to the question a reader is really asking: is this a Christian book, or does it just have the word Christian on the cover?
We do not decide whose theology is right. Catholic, Orthodox, Baptist, Reformed, Lutheran, Methodist, Pentecostal, Anglican, Anabaptist, and non-denominational authors all sign the same six points, and they disagree with each other about a great deal else. Baptism, communion, church government, the end times, spiritual gifts, and the role of women in ministry are not on this list and never will be. Those are questions for you, your church, and your tradition.
What we do is simpler. We confirm that a real, identified person put their name to these six points, and we hold them to it. If an author will not sign, the book is not certified — that is all that happens, and we say nothing further about the author or about anyone else. If an author signs and the book plainly contradicts one of the six, that is a false statement made under a verified identity, and it is handled the same way as a fabricated citation or a fake endorsement.
The basis for these six statements — for anyone who wants to know what this rests on.
