Epistle of Peter
In his "Church History", Eusebius writes that Bishop Serapion of Antioch had been informed that a Christian community in Rhosus was using the Gospel of Peter in their liturgy and had sent a letter authorizing them to do so, while also denying that such Gospel was actually written by Saint Peter. Later, however, Serapion was informed that the Gospel of Peter "hid an heresy", which he attributed to a certain Marcian and that he identified with docetism. Serapion reports that he read the Gospel carefully and had the opportunity "to find, along with much of the Savior's true doctrine, some additions". Eusebius also states that several works had been attributed to Peter: the First Epistle of Peter, the Second Epistle of Peter, the Acts of Peter, the Gospel of Peter, the Preaching of Peter and the Apocalypse of Peter. He accepts the First Epistle of Peter as genuine, while he rejects all the others as spurious. In his "De Viris Illustribus", Jerome writes that the Gospel of Peter was written by Serapion, a statement that leads scholars to think he had misunderstood Eusebius's account in "Church History".
