XVII. For we have learned to believe in and to teach the Deity of the Son from their great and lofty utterances. And what utterances are these? These: God— The Word— He That Was In The Beginning and With The Beginning, and The Beginning. “In the Beginning was The Word, and the Word was with God, and the Word was God,” and “With You is the Beginning,” and “He who calls her The Beginning from generations.” Then the Son is Only-begotten: The only “begotten Son which is in the bosom of the Father, it says, He has declared Him.” The Way, the Truth, the Life, the Light. “I am the Way, the Truth, and the Life;” and “I am the Light of the World.” Wisdom and Power, “Christ, the Wisdom of God, and the Power of God.” The Effulgence, the Impress, the Image, the Seal; “Who being the Effulgence of His glory and the Impress of His Essence,” and “the Image of His Goodness,” and “Him has God the Father sealed.” Lord, King, He That Is, The Almighty. “The Lord rained down fire from the Lord;” and “A sceptre of righteousness is the sceptre of Your Kingdom;” and “Which is and was and is to come, the Almighty” — all which are clearly spoken of the Son, with all the other passages of the same force, none of which is an afterthought, or added later to the Son or the Spirit, any more than to the Father Himself. For Their Perfection is not affected by additions. There never was a time when He was without the Word, or when He was not the Father, or when He was not true, or not wise, or not powerful, or devoid of life, or of splendour, or of goodness.
But in opposition to all these, do you reckon up for me the expressions which make for your ignorant arrogance, such as “My God and your God,” or greater, or created, or made, or sanctified; Add, if you like, Servant and Obedient and Gave and Learnt, and was commanded, was sent, can do nothing of Himself, either say, or judge, or give, or will. And further these—His ignorance, subjection, prayer, asking, increase, being made perfect. And if you like even more humble than these; such as speak of His sleeping, hungering, being in an agony, and fearing; or perhaps you would make even His Cross and Death a matter of reproach to Him. His Resurrection and Ascension I fancy you will leave to me, for in these is found something to support our position. A good many other things too you might pick up, if you desire to put together that equivocal and intruded god of yours, Who to us is True God, and equal to the Father. For every one of these points, taken separately, may very easily, if we go through them one by one, be explained to you in the most reverent sense, and the stumbling-block of the letter be cleaned away— that is, if your stumbling at it be honest, and not wilfully malicious. To give you the explanation in one sentence. What is lofty you are to apply to the Godhead, and to that Nature in Him which is superior to sufferings and incorporeal; but all that is lowly to the composite condition of Him who for your sakes made Himself of no reputation and was Incarnate— yes, for it is no worse thing to say, was made Man, and afterwards was also exalted. The result will be that you will abandon these carnal and grovelling doctrines, and learn to be more sublime, and to ascend with His Godhead, and you will not remain permanently among the things of sight, but will rise up with Him into the world of thought, and come to know which passages refer to His Nature, and which to His assumption of Human Nature.
XIX. For He Whom you now treat with contempt was once above you. He Who is now Man was once the Uncompounded. What He was He continued to be; what He was not He took to Himself. In the beginning He was, uncaused; for what is the Cause of God? But afterwards for a cause He was born. And that cause was that you might be saved, who insult Him and despise His Godhead, because of this, that He took upon Him your denser nature, having converse with Flesh by means of Mind. While His inferior Nature, the Humanity, became God, because it was united to God, and became One Person because the Higher Nature prevailed in order that I too might be made God so far as He is made Man. He was born— but He had been begotten: He was born of a woman— but she was a Virgin. The first is human, the second Divine. In His Human nature He had no Father, but also in His Divine Nature no Mother. Both these belong to Godhead. He dwelt in the womb— but He was recognized by the Prophet, himself still in the womb, leaping before the Word, for Whose sake He came into being. He was wrapped in swaddling clothes — but He took off the swathing bands of the grave by His rising again. He was laid in a manger— but He was glorified by Angels, and proclaimed by a star, and worshipped by the Magi. Why are you offended by that which is presented to your sight, because you will not look at that which is presented to your mind? He was driven into exile into Egypt— but He drove away the Egyptian idols. He had no form nor comeliness in the eyes of the Jews — but to David He is fairer than the children of men. And on the Mountain He was bright as the lightning, and became more luminous than the sun, initiating us into the mystery of the future.
