But again, those who assert that He was simply a mere man, begotten by Joseph, remaining in the bondage of the old disobedience, are in a state of death having been not as yet joined to the Word of God the Father, nor receiving liberty through the Son, as He does Himself declare: If the Son shall make you free, you shall be free indeed. John 8:36 But, being ignorant of Him who from the Virgin is Emmanuel, they are deprived of His gift, which is eternal life; Romans 6:23 and not receiving the incorruptible Word, they remain in mortal flesh, and are debtors to death, not obtaining the antidote of life. To whom the Word says, mentioning His own gift of grace: I said, You are all the sons of the Highest, and gods; but you shall die like men. He speaks undoubtedly these words to those who have not received the gift of adoption, but who despise the incarnation of the pure generation of the Word of God, defraud human nature of promotion into God, and prove themselves ungrateful to the Word of God, who became flesh for them. For it was for this end that the Word of God was made man, and He who was the Son of God became the Son of man, that man, having been taken into the Word, and receiving the adoption, might become the son of God. For by no other means could we have attained to incorruptibility and immortality, unless we had been united to incorruptibility and immortality. But how could we be joined to incorruptibility and immortality, unless, first, incorruptibility and immortality had become that which we also are, so that the corruptible might be swallowed up by incorruptibility, and the mortal by immortality, that we might receive the adoption of sons?
For this reason [it is, said], Who shall declare His generation? Isaiah 53:8 since He is a man, and who shall recognise Him? Jeremiah 17:9 But he to whom the Father which is in heaven has revealed Him, Matthew 16:16 knows Him, so that he understands that He who was not born either by the will of the flesh, or by the will of man, John 1:13 is the Son of man, this is Christ, the Son of the living God. For I have shown from the Scriptures, that no one of the sons of Adam is as to everything, and absolutely, called God, or named Lord. But that He is Himself in His own right, beyond all men who ever lived, God, and Lord, and King Eternal, and the Incarnate Word, proclaimed by all the prophets, the apostles, and by the Spirit Himself, may be seen by all who have attained to even a small portion of the truth. Now, the Scriptures would not have testified these things of Him, if, like others, He had been a mere man. But that He had, beyond all others, in Himself that pre-eminent birth which is from the Most High Father, and also experienced that pre-eminent generation which is from the Virgin, Isaiah 7:14 the divine Scriptures do in both respects testify of Him: also, that He was a man without comeliness, and liable to suffering; Isaiah 53:2 that He sat upon the foal of an ass; Zechariah 9:9 that He received for drink, vinegar and gall; that He was despised among the people, and humbled Himself even to death and that He is the holy Lord, the Wonderful, the Counsellor, the Beautiful in appearance, and the Mighty God, Isaiah 9:6 coming on the clouds as the Judge of all men; Daniel 7:13 — all these things did the Scriptures prophesy of Him.
