The Bible is authoritative, but which books are in the Bible? Whose word should we trust? The Bible should be the axiomatic starting point and ending point for all Christian doctrine, including the doctrine of canon. Inside, Dr. Kayser defends the Protestant doctrine that “only God can identify His word,” and He did so through the very prophets who gave us the Scriptures. In other words, if God’s Word is the highest authority in our lives, there can be no higher authority to which we can appeal in order to prove the doctrine of canon. Chapter 10 shows that the church of the first millennium took the same approach to canonization and clearly sided with the Reformation and against the reactionary Roman Catholic and Eastern Orthodox approaches to canon since the Reformation. The Bible’s self-referential statements are sufficient to completely settle the question of canonicity. This presuppositional approach to canonicity is the only adequate approach that will stand up against all criticism.
