1. One epistle of Peter, that called the first, is acknowledged as genuine. And this the ancient elders used freely in their own writings as an undisputed work. But we have learned that his extant second Epistle does not belong to the canon; yet, as it has appeared profitable to many, it has been used with the other Scriptures.
2. The so-called Acts of Peter, however, and the Gospel which bears his name, and the Preaching and the Apocalypse, as they are called, we know have not been universally accepted, because no ecclesiastical writer, ancient or modern, has made use of testimonies drawn from them.
3. But in the course of my history I shall be careful to show, in addition to the official succession, what ecclesiastical writers have from time to time made use of any of the disputed works, and what they have said in regard to the canonical and accepted writings, as well as in regard to those which are not of this class.
4. Such are the writings that bear the name of Peter, only one of which I know to be genuine and acknowledged by the ancient elders.
5. Paul's fourteen epistles are well known and undisputed. It is not indeed right to overlook the fact that some have rejected the Epistle to the Hebrews, saying that it is disputed by the church of Rome, on the ground that it was not written by Paul. But what has been said concerning this epistle by those who lived before our time I shall quote in the proper place. In regard to the so-called Acts of Paul, I have not found them among the undisputed writings.
6. But as the same apostle, in the salutations at the end of the Epistle to the Romans, has made mention among others of Hermas, to whom the book called The Shepherd is ascribed, it should be observed that this too has been disputed by some, and on their account cannot be placed among the acknowledged books; while by others it is considered quite indispensable, especially to those who need instruction in the elements of the faith. Hence, as we know, it has been publicly read in churches, and I have found that some of the most ancient writers used it.
7. This will serve to show the divine writings that are undisputed as well as those that are not universally acknowledged.
