Obviously these facts and the name (which falls in with the theory--itself also somewhat unsubstantial--that Justin's Gospel must have a 'Petrine' character) are quite insufficient to build upon.

The Protevangelium of James, which it is thought might have been used in an earlier form than that which has come down to us, contains the legend of the cave, and has apparently a similar view to the Gospel last mentioned as to the perpetual virginity of Mary.

The kindred Evangelium Thomae has the 'ploughs and yokes.' And there are some similarities of language between the Protevangelium and Justin's Gospel, which will come under review later [Endnote 110:4].
It does not, however, appear to have been noticed that these Gospels satisfy most imperfectly the conditions of the problem.

We know that the Gospel according to the Hebrews in its Nazarene form omitted the whole section Matt.i.

18--ii.
