Again, Justin makes Trypho demand:--

"Answer me then, first, how you can show that there is another God
besides the Maker of all things; [70:1] and then you will show
[further], that He submitted to be born of the Virgin.

"I replied, Give me permission first of all to quote certain passages
from the Prophecy of Isaiah which refer to the office of forerunner
discharged by John the Baptist." (Dial. I.)

Lastly:--

"Now, assuredly, Trypho, I shall show that, in the vision of Moses,
this same One alone, Who is called an Angel, and Who is God,
appeared to and communed with Moses.... Even so here, the
Scriptures, in announcing that the angel of the Lord appeared unto
Moses, and in afterwards declaring Him to be Lord and God, speaks of
the same One, Whom it declares by the many testimonies already
quoted to be minister to God, Who is above the world, above Whom
there is no other." (Dial. ch. lx.)

In order not to weary the reader, I give the remainder in a note. [71:1]

The reader will observe that the assertions of Justin, which I have
given, are the strongest that could be made by any one who holds the
Godhead of Christ, and yet holds that that Godhead is not an independent
Divine Existence, but derived from the Father Who begat Him, and, by
begetting, fully communicated to His Son or Offspring His own Godhead.
