The same may be said with only a little less confidence of the sections of the preliminary history.
Taking these salient points together with the mass of the coincidences each in its place, and with the due weight assigned to it, the conviction seems forced upon us that Justin did either mediately or immediately, and most probably immediately and directly, make use of our Canonical Gospels.
On the other hand, the argument that he used, whether in addition to these or exclusively, a Gospel now lost, rests upon the following data.

Justin apparently differs from the Synoptics in giving the genealogy of Mary, not of Joseph.

In Apol.i.34 he says that Cyrenius was the first governor (procurator) of Judaea, instead of saying that the census first took place under Cyrenius.
[It should be remarked, however, that in another place, Dial.

78, he speaks of 'the census which then took place for the first time ([Greek: ousaes tote protaes]) under Cyrenius.'] He states that Mary brought forth her Son in a cave near the village of Bethlehem.

He ten times over speaks of the Magi as coming from Arabia, and not merely from the East.
