Dialogue with Trypho
Chapter 63: It is proven that this God was incarnated
And Trypho said, "This point has been convincingly proved to me through many arguments, my friend. It remains, then, to prove that He became man by the Virgin, according to the will of His Father; and that He was crucified and died. Also, clearly prove that after this, He rose again and ascended to heaven."
I replied, "This, too, has already been demonstrated by me in the previously quoted words of the prophecies, my friends. By recalling and explaining these passages for your benefit, I will try to lead you to agree with me on this matter. The passage from Isaiah, 'Who shall declare His generation? for His life is taken away from the earth,'—does it not seem to you to refer to One who, without descent from men, was handed over to death by God for the sins of the people? Of whose blood Moses, as I mentioned before, used a parable to say He would wash His garments in the blood of the grape; since His blood did not come from human lineage, but from the will of God.
And then, what David says, 'In the splendors of Thy holiness have I begotten Thee from the womb, before the morning star. The Lord has sworn, and will not change His mind, Thou art a priest forever, after the order of Melchizedek,'—does this not tell you that He existed from of old, and that God, the Father of all, intended Him to be born of a human womb? Speaking in other words, which have also been previously quoted, he says: 'Thy throne, O God, is forever and ever: a scepter of righteousness is the scepter of Thy kingdom.
Thou hast loved righteousness and hated wickedness; therefore God, Thy God, has anointed Thee with the oil of gladness above Thy companions. [He has anointed Thee] with myrrh, and oil, and cassia from Thy garments, from the ivory palaces, whereby they made Thee glad. The daughters of kings are in Thy honor. The queen stood at Thy right hand, clad in garments embroidered with gold. Listen, O daughter, and look, and incline your ear, forget your people and your father's house; and the King shall desire your beauty, for He is your Lord, and you shall worship Him.' Therefore, these words explicitly testify that He is recognized by Him who established these things, as worthy of worship, as God and as Christ.
Furthermore, the word of God addresses those who believe in Him as being one soul, one congregation, and one church, as if to a daughter; it addresses the church which has arisen from His name and shares His name (for we are all called Christians), as clearly stated in the following words, which teach us also to let go of our old ancestral customs, when they say: 'Listen, O daughter, and look, and incline your ear; forget your people and your father's house, and the King shall desire your beauty, for He is your Lord, and you shall worship Him.'"
