Gospel of the Ebionites closely with the lost "Gospel of the Twelve". It shows no dependence on the Gospel of John and is similar in nature to the harmonized gospel sayings based on the Synoptic Gospels used by Justin Martyr, although a relationship between them, if any, is uncertain. There is a similarity between the gospel and a source document contained within the Clementine "Recognitions" (1.27–71), conventionally referred to by scholars as the "Ascents of James", with respect to the command to abolish the Jewish sacrifices. Epiphanius is believed to have come into possession of a gospel that he attributed to the Ebionites when
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.
