New Testament document, in addition to some other sources, to write their individual gospel accounts. These three gospels are called the Synoptic gospels because they include many of the same stories, often in the same sequence, and sometimes exactly the same wording. Scholars agree that the Gospel of John was written last, by using a different tradition and body of testimony. In addition, most scholars agree that the author of Luke wrote the Acts of the Apostles. Scholars hold that these books constituted two halves of a single work, Luke-Acts. Strictly speaking, each gospel and the book of Acts is arguably anonymous.
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.
