God begat a beginning — the Logos, which was himself.

“I shall give you another testimony, my friends,” said I, “from the Scriptures, that God begat before all creatures a Beginning, [who was] a certain rational power [proceeding] from Himself, who is called by the Holy Spirit, now the Glory of the Lord, now the Son, again Wisdom, again an Angel, then God, and then Lord and Logos; and on another occasion He calls Himself Captain, when He appeared in human form to Joshua the son of Nave (Nun). For He can be called by all those names, since He ministers to the Father’s will, and since He was begotten of the Father by an act of will; just as we see happening among ourselves: for when we give out some word, we beget the word; yet not by abscission, so as to lessen the word [which remains] in us, when we give it out: and just as we see also happening in the case of a fire, which is not lessened when it has kindled [another], but remains the same; and that which has been kindled by it likewise appears to exist by itself, not diminishing that from which it was kindled. The Word of Wisdom, who is Himself this God begotten of the Father of all things, and Word, and Wisdom, and Power, and the Glory of the Begetter, will bear evidence to me, when He speaks by Solomon the following: ‘If I shall declare to you what happens daily, I shall call to mind events from everlasting, and review them. The Lord made me the beginning of His ways for His works. From everlasting He established me in the beginning, before He had made the earth, and before He had made the deeps, before the springs of the waters had issued forth, before the mountains had been established. Before all the hills He begets me.

Dialogue with Trypho
Chapter LXI

Jesus wrestled with Jacob and appeared in the burning bush

And I replied, “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. For the Scripture says thus: ‘The Angel of the Lord appeared to him in a flame of fire from the bush; and he sees that the bush burns with fire, but the bush was not consumed. And Moses said, I will turn aside and see this great sight, for the bush is not burnt. And when the Lord saw that he is turning aside to behold, the Lord called to him out of the bush.’ In the same manner, therefore, in which the Scripture calls Him who appeared to Jacob in the dream an Angel, then [says] that the same Angel who appeared in the dream spoke to him, saying, ‘I am the God that appeared to thee when thou didst flee from the face of Esau thy brother;’ and [again] says that, in the judgment which befell Sodom in the days of Abraham, the Lord had inflicted the punishment of the Lord who [dwells] in the heavens;—even so here, the Scripture, in announcing that the Angel of the Lord appeared to 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 [God].

Dialogue with Trypho
Chapter LX

Yahweh (the Christ) visited Abraham by the Oaks

I replied again, “If I could not have proved to you from the Scriptures that one of those three is God, and is called Angel, because, as I already said, He brings messages to those to whom God the Maker of all things wishes [messages to be brought], then in regard to Him who appeared to Abraham on earth in human form in like manner as the two angels who came with Him, and who was God even before the creation of the world, it were reasonable for you to entertain the same belief as is entertained by the whole of your nation.”

“… And now have you not perceived, my friends, that one of the three, who is both God and Lord, and ministers to Him who is in the heavens, is Lord of the two angels?”

Justin Martyr
Dialogue with Typho
Chapter LVI

When you say that this Christ existed as God before the ages..

And Trypho said, “We have heard what you think of these matters. Resume the discourse where you left off, and bring it to an end. For some of it appears to me to be paradoxical, and wholly incapable of proof. For when you say that this Christ existed as God before the ages, then that He submitted to be born and become man, yet that He is not man of man, this [assertion] appears to me to be not merely paradoxical, but also foolish.”

Justin Martyr
Dialogue with Trypho
Chapter XLVIII

Gentiles should not be forced to follow Jewish law

And Trypho again inquired, “But if some one, knowing that this is so, after he recognizes that this man is Christ, and has believed in and obeys Him, wishes, however, to observe these [institutions], will he be saved?” I said, “In my opinion, Trypho, such an one will be saved, if he does not strive in every way to persuade other men, —I mean those Gentiles who have been circumcised from error by Christ, to observe the same things as himself, telling them that they will not be saved unless they do so. This you did yourself at the commencement of the discourse, when you declared that I would not be saved unless I observe these institutions.”
