36. That the Son is the Co-existing Word, argued from the New Testament. Texts from the Old Testamentcontinued; especially Psalm 110:3. Besides, the Word in Old Testamentmay be Son in New, as Spirit in Old Testamentis Paraclete in New. Objection from Acts 10:36; answered by parallels, such as 1 Corinthians 1:5. Lev. 9:7. etc. Necessity of the Word's taking flesh, viz. to sanctify, yet without destroying, the flesh
33 And this is usual with Scripture, to express itself in inartificial and simple phrases. For so also in Numbers we shall find, Moses said to Raguel the Midianite, the father-in-law of Moses; for there was not one Moses who spoke, and another whose father-in-law was Raguel, but Moses was one. And if in like manner the Word of God is called Wisdom and Power and Right-Hand and Arm and the like, and if in His love to man He has become one with us, putting on our first-fruits and blended with it, therefore the other titles also have, as was natural, become the Word's portions. For that John has said, that in the beginning was the Word, and He with God and Himself God, and all things through Him, and without Him nothing made, shows clearly that even man is the formation of God the Word. If then after taking him, when enfeebled, into Himself, He renews him again through that sure renewal unto endless permanence, and therefore is made one with him in order to raise him to a diviner lot, how can we possibly say that the Word was sent through the Man who was from Mary, and reckon Him, the Lord of Apostles, with the other Apostles, I mean prophets, who were sent by Him? And how can Christ be called a mere man? On the contrary, being made one with the Word, He is with reason called Christ and Son of God, the prophet having long since loudly and clearly ascribed the Father's subsistence to Him, and said, 'And I will send My Son Christ,' and in the Jordan, 'This is My Well-beloved Son.' For when He had fulfilled His promise, He showed, as was suitable, that He was He whom He said He had sent.
34. Let us then consider Christ in both ways, the divine Word made one in Mary with Him which is from Mary. For in her womb the Word fashioned for Himself His house, as at the beginning He formed Adam from the earth; or rather more divinely, concerning whom Solomon too says openly, knowing that the Word was also called Wisdom, 'Wisdom built herself an house;' which the Apostle interprets when he says, 'Which house are we,' and elsewhere calls us a temple, as far as it is fitting to God to inhabit a temple, of which the image, made of stones, He by Solomon commanded the ancient people to build; whence, on the appearance of the Truth, the image ceased. For when the ruthless men wished to prove the image to be the truth, and to destroy that true habitation which we surely believe His union with us to be, He threatened them not; but knowing that their crime was against themselves, He says to them, 'Destroy this Temple, and in three days I will raise it up,' He, our Saviour, surely showing thereby that the things about which men busy themselves, carry their dissolution with them. For unless the Lord had built the house, and kept the city, in vain did the builders toil, and the keepers watch. And so the works of the Jews are undone, for they were a shadow; but the Church is firmly established; it is 'founded on the rock,' and 'the gates of hades shall not prevail against it. ' Theirs it was to say, 'Why do You, being a man, make Yourself God?' and their disciple is the Samosatene; whence to his followers with reason does he teach his heresy. But 'we did not so learn Christ, if so be that we heard' Him, and were taught from Him, 'putting off the old man, which is corrupt according to the deceitful lusts,' and taking up 'the new, which after God is created in righteousness and true holiness. ' Let Christ then in both ways be religiously considered.
35. But if Scripture often calls even the body by the name of Christ, as in the blessed Peter's words to Cornelius, when he teaches him of 'Jesus of Nazareth, whom God anointed with the Holy Ghost,' and again to the Jews, 'Jesus of Nazareth, a Man approved of God for you,' and again the blessed Paul to the Athenians, 'By that Man, whom He ordained, giving assurance to all men, in that He raised Him from the dead ' (for we find the appointment and the mission often synonymous with the anointing; from which any one who will may learn, that there is no discordance in the words of the sacred writers, but that they but give various names to the union of God the Word with the Man from Mary, sometimes as anointing, sometimes as mission, sometimes as appointment), it follows that what the blessed Peter says is right, and he proclaims in purity the Godhead of the Only begotten, without separating the subsistence of God the Word from the Man from Mary (perish the thought! For how should he, who had heard in so many ways, 'I and the Father are one,' and 'He that has seen Me, has seen the Father?)' In which Man, after the resurrection also, when the doors were shut, we know of His coming to the whole band of the Apostles, and dispersing all that was hard to believe in it by His words, 'Handle Me and see, for a spirit has not flesh and bones, as you see Me have.' And He did not say, 'This,' or 'this Man which I have taken to Me,' but 'Me.' Wherefore the Samosatene will gain no allowance, being refuted by so many arguments for the union of God the Word, nay by God the Word Himself, who now brings the news to all, and assures them by eating, and permitting to them that handling of Him which then took place. For certainly he who gives food to others, and they who give him, touch hands. For 'they gave Him,' Scripture says, 'a piece of a broiled fish and of an honey-comb, and' when He had 'eaten before them, He took the remains and gave to them. ' See now, though not as Thomas was allowed, yet by another way, He afforded to them full assurance, in being touched by them; but if you would now see the scars, learn from Thomas. 'Reach hither your hand and thrust it into My side, and reach hither your finger and behold My hands;' so says God the Word, speaking of His own side and hands, and of Himself as whole man and God together, first affording to the Saints even perception of the Word through the body, as we may consider, by entering when the doors were shut; and next standing near them in the body and affording full assurance. So much may be conveniently said for confirmation of the faithful, and correction of the unbelieving.
36. And so let Paul of Samosata also stand corrected on hearing the divine voice of Him who said 'My body,' not 'Christ besides Me who am the Word,' but 'Him with Me, and Me with Him.' For I the Word am the chrism, and that which has the chrism from Me is the Man; not then without Me could He be called Christ, but being with Me and I in Him. Therefore the mention of the mission of the Word shows the uniting which took place with Jesus, born of Mary, Whose Name means Saviour, not by reason of anything else, but from the Man's being made one with God the Word. This passage has the same meaning as 'the Father that sent Me,' and 'I came not of Myself, but the Father sent Me. ' For he has given the name of mission to the uniting with the Man, with Whom the Invisible nature might be known to men, through the visible. For God changes not place, like us who are hidden in places, when in the fashion of our littleness He displays Himself in His existence in the flesh; for how should He, who fills the heaven and the earth? But on account of the presence in the flesh the just have spoken of His mission. Therefore God the Word Himself is Christ from Mary, God and Man; not some other Christ but One and the Same; He before ages from the Father, He too in the last times from the Virgin; invisible before even to the holy powers of heaven, visible now because of His being one with the Man who is visible; seen, I say, not in His invisible Godhead but in the operation of the Godhead through the human body and whole Man, which He has renewed by its appropriation to Himself. To Him be the adoration and the worship, who was before, and now is, and ever shall be, even to all ages. Amen.
