Aphrahat the Persian Sage : Again, listen concerning the title Son of God, by which we have called him. They [the Jews] say that "though God has no son, you make that crucified Jesus, the firstborn son of God." Yet he called Israel "my firstborn" when he sent to Pharaoh through Moses and said to him, "Israel is my firstborn; I have said to you, let my son go to serve me, and if you are not willing to let (him) go, lo! I will slay your son, your firstborn." And also through the prophet he testified concerning this and reproved them and said to the people, "Out of Egypt have I called my son. As I called them, so they went and worshiped Baal and offered incense to the graven images." And Isaiah said concerning them, "Children have I reared and brought up, and they have rebelled against me." And again it is written, "You are the children of the Lord your God." And about Solomon he said, "He shall be a son to me, and I will be a Father to him." So also we call the Christ "the Son of God" because through him we have gained the knowledge of God; even as he called Israel my firstborn son and as he said concerning Solomon, "He shall be a son to me." — DEMONSTRATION 17.4 Justin Martyr : So that you ought rather to desist from the love of strife, and repent before the great day of judgment come, wherein all those of your tribes who have pierced this Christ shall mourn as I have shown has been declared by the Scriptures. And I have explained that the Lord swore, "after the order of Melchizedek," and what this prediction means; and the prophecy of Isaiah which says, "His burial is taken away from the midst," I have already said, referred to the future burying and rising again of Christ; and I have frequently remarked that this very Christ is the Judge of all the living and the dead. And Nathan likewise, speaking to David about Him, thus continued: "I will be His Father, and He shall be my Son; and my mercy shall I not take away from Him, as I did from them that went before Him; and I will establish Him in my house, and in His kingdom for ever." And Ezekiel says, "There shall be no other prince in the house but He." For He is the chosen Priest and eternal King, the Christ, inasmuch as He is the Son of God; and do not suppose that Isaiah or the other prophets speak of sacrifices of blood or libations being presented at the altar on His second advent, but of true and spiritual praises and giving of thanks. — Dialogue with Trypho, Chapter CXVIII
