Dr.Hilgenfeld has also noticed the phrase [Greek: charan de labousa Mariam] as common to Justin and the Protevangelium [Endnote 130:1].

This, too, may belong to the older original of the latter work.

The other verbal coincidences with the Gospel according to the Hebrews in the account of the Baptism, and with that of Thomas in the 'ploughs and yokes,' have been already mentioned, and are, I believe, along with those just discussed, all that can be directly referred to an apocryphal source.
Besides these there are some coincidences in form between quotations as they appear in Justin and in other writers, such as especially the Clementine Homilies.

These are thought to point to the existence of a common Gospel (now lost) from which they may have been extracted.

It is unnecessary to repeat what has been said about one of these passages ('Let your yea be yea,' &c.).
