Synoptic Gospels synoptic gospels are similar to John: all are composed in Koine Greek, have a similar length, and were completed within a century of Jesus' death. They also differ from non-canonical sources, such as the Gospel of Thomas, in that they belong to the ancient genre of biography, collecting not only Jesus' teachings, but recounting in an orderly way his origins, his ministry and miracles, and his passion and resurrection. In content and in wording, though, the synoptics diverge widely from John but have a great deal in common with each other. Though each gospel includes some unique material, the majority
Gospel of Peter in the canonical gospels was transmitted orally, through readings in the churches, i.e. that the text is based on what the author "remembers" about the other gospels, together with his own embellishments. Ron Cameron and others have further speculated the Gospel of Peter was written independently of the synoptic gospels using an early proto-gospel. A consequence of this is the potential existence of a source text that formed the basis of the passion narratives in Matthew, Luke, and Mark, as well as in Peter. Origen makes mention of the Gospel of Peter as agreeing with the tradition of the Hebrews.
