This Gospel is mentioned by Serapion as in use in the church of Rhossus (quoted by Eusebius, Bk. VI. chap. 12, below), but was rejected by him because of the heretical doctrines which it contained. It is mentioned again by Eusebius, III. 25, only to be rejected as heretical; also by Origen (in Matt. Vol. X. 17) and by Jerome (de vir. ill. 1), who follows Eusebius in pronouncing it an heretical work employed by no early teachers of the Christian Church. Lipsius regards it as probably a Gnostic recast of one of the Canonical Gospels. From Serapion’s account of this Gospel (see below, Bk. VI. chap. 12), we see that it differs from the Canonical Gospels, not in denying their truth, or in giving a contradictory account of Christ’s life, but rather in adding to the account given by them. This, of course, favors Lipsius’ hypothesis; and in any case he is certainly quite right in denying that the Gospel was an original work made use of by Justin Martyr, and that it in any way lay at the base of our present Gospel of Mark. The Gospel (as we learn from the same chapter) was used by the Docetæ, but that does not imply that it contained what we call Docetic ideas of Christ’s body (cf. note 8 on that chapter). The Gospel is no longer extant. See Lipsius, in Smith and Wace’s Dict. of Christ. Biog. II. p. 712.
