Isaias 45:14

As, therefore, the primary and greatest power of the animal essence came into existence, an image (of the only begotten Son); so also the devil, who is the ruler of this world, constitutes the power of the material essence, as Beelzebub is of the essence of demons which emanates from anxiety. (In consequence of this,) Sophia from above exerted her energy from the Ogdoad to the Hebdomad. For the Demiurge, they say, knows nothing at all, but is, according to them, devoid of understanding, and silly, and is not conscious of what he is doing or working at. But in him, while thus in a state of ignorance that even he is producing, Sophia wrought all sorts of energy, and infused vigour (into him). …

2. Now they seek to exhibit the foundation for their dogma by citing the word in the law, “I am the God of your fathers: ye shall have no other gods beside me;” and again in another passage, “I am the first,” He saith, “and the last; and beside me there is none other.” Thus they say they prove that God is one. And then they answer in this manner: “If therefore I acknowledge Christ to be God, He is the Father Himself, if He is indeed God; and Christ suffered, being Himself God; and consequently the Father suffered, for He was the Father Himself.” But the case stands not thus; for the Scriptures do not set forth the matter in this manner. But they make use also of other testimonies, and say, Thus it is written: “This is our God, and there shall none other be accounted of in comparison of Him. …

4. Let us, as I said, see how he is confuted, and then let us set forth the truth. Now he quotes the words, “Egypt has laboured, and the merchandise of Ethiopia and the Sabeans,” and so forth on to the words, “For Thou art the God of Israel, the Saviour.” And these words he cites without understanding what precedes them. For whenever they wish to attempt anything underhand, they mutilate the Scriptures. But let him quote the passage as a whole, and he will discover the reason kept in view in writing it. For we have the beginning of the section a little above; and we ought, of course, to commence there in showing to whom and about whom the passage speaks. For above, the beginning of the section stands thus: “Ask me concerning my sons and my daughters, and concerning the work of my hands command ye me. …

In Genesis: “And God said unto Jacob, Arise, and go up to the place of Bethel, and dwell there; and make there an altar to that God who appeared unto thee when thou fleddest from the face of thy brother Esau.” Also in Isaiah: “Thus saith the Lord, the God of Sabaoth, Egypt is wearied; and the merchandise of the Ethiopians, and the tall men of the Sabeans, shall pass over unto Thee, and shall be Thy servants; and shall walk after Thee bound with chains; and shall worship Thee, and shall pray to Thee, because God is in Thee, and there is no other God beside Thee. For Thou art God, and we knew it not, O God of Israel, our Saviour. They shall all be confounded and fear who oppose Thee, and shall fall into confusion.” Likewise in the same: “The voice of one crying in the wilderness, Prepare ye the way of the Lord, make straight the paths of our God. …

Therefore the Most High God, and Parent of all, when He had purposed to transfer His religion, sent from heaven a teacher of righteousness, that in Him or through Him He might give a new law to new worshippers; not as He had before done, by the instrumentality of man. Nevertheless it was His pleasure that He should be born as a man, that in all things He might be like His supreme Father. For God the Father Himself, who is the origin and source of all things, inasmuch as He is without parents, is most truly named by Trismegistus “fatherless” and “motherless,” because He was born from no one. For which reason it was befitting that the Son also should be twice born, that He also might become “fatherless” and “motherless.” For in His first nativity, which was spiritual, He was “motherless,” because He was begotten by God the Father alone, without the office of a mother. …

We may use an example more closely connected with us. When any one has a son whom he especially loves, who is still in the house, and in the power of his father, although he concede to him the name and power of a master, yet by the civil law the house is one, and one person is called master. So this world is the one house of God; and the Son and the Father, who unanimously inhabit the world, are one God, for the one is as two, and the two are as one. Nor is that wonderful, since the Son is in the Father, for the Father loves the Son, and the Father is in the Son; for He faithfully obeys the will of the Father, nor does He ever do nor has done anything except what the Father either willed or commanded. …

That these things should thus take place as I have set them forth, the prophets had before predicted. In the writings of Solomon it is thus written: “The womb of a virgin was strengthened, and conceived: and a virgin was impregned, and became a mother in great pity.” In Isaiah it is thus written: “Behold, a virgin shall conceive, and bear a son, and ye shall call His name Immanuel;” which, being interpreted, is God with us. For He was with us on the earth, when He assumed flesh; and He was no less God in man, and man in God. That He was both God and man was declared before by the prophets. That He was God, Isaiah thus declares: “They shall fall down unto Thee, they shall make supplication unto Thee; since God is in Thee, and we knew it not, even the God of Israel. …

In his fourth chapter he denies the distinction of the terms of evangelists and apostles, and refuses to allow, as the teaching of the orthodox Fathers has allowed, the terms of divine dignity to be understood of the divine nature, while the terms of humility, spoken in human sense, are applied to the nature assumed; whence the rightminded can easily detect the kinship with impiety. For Arius and Eunomius, asserting the only begotten Son of God to be a creature, and made out of the non-existent, and a servant, have ventured to apply to His godhead what is said in lowly and human sense; establishing by such means the difference of substance and the unlike ness. Besides this, to be brief, he argues that the very impassible and immutable Godhead of the Christ suffered, and was crucified, dead, and buried. …

23. Moreover if, as the heretics hold, the Son were creature or work, but not as one of the creatures, because of His excelling them in glory, it were natural that Scripture should describe and display Him by a comparison in His favour with the other works; for instance, that it should say that He is greater than Archangels, and more honourable than the Thrones, and both brighter than sun and moon, and greater than the heavens. But he is not in fact thus referred to; but the Father shews Him to be His own proper and only Son, saying, ‘Thou art My Son,’ and ‘This is My beloved Son, in whom I am well pleased.’ Accordingly the Angels ministered unto Him, as being one beyond themselves; and they worship Him, not as being greater in glory, but as being some one beyond all the creatures, and beyond themselves, and alone the Father’s proper Son according to essence. …

38. Again, how clear is the declaration made by God the Father through Isaiah concerning our Lord! He says, For thus saith the Lord, the holy God of Israel, Who made the things to come, Ask me concerning your sons and your daughters, and concerning the works of My hands command ye Me. I have made the earth and man upon it, I have commanded all the stars, I have raised up a King with righteousness, and all His ways are straight. He shall build My city, and shall turn back the captivity of My people, not for price nor reward, saith the Lord of Sabaoth. Egypt shall labour, and the merchandise of the Ethiopians and Sabeans. Men of stature shall come over unto Thee and shall be Thy servants, and shall follow after Thee, bound in chains, and shall worship Thee and make supplication unto Thee, for God is in Thee and there is no God beside Thee. …

78. What, then, moves you to say that to God the Father or to His Christ there is glory, life, greatness, or power, in the Holy Spirit, and to refuse to say with the Holy Spirit? Is it that you are afraid of seeming to join the Spirit with the Father and the Son? But hear what is written of the Spirit: “For the law of the Spirit is life in Christ Jesus.” And in another place God the Father says: “They shall worship Thee, and in Thee they shall make supplication.” God the Father says that we ought to pray in Christ; and do you think that it is any derogation to the Spirit if the glory of Christ is said to be in Him?

He it is then of whom the Prophet says: “For in Thee is God, and there is no God beside Thee. For Thou art our God and we knew Thee not, O God of Israel the Saviour.” Who “afterwards appeared on earth and conversed with men.” Of whom and in whose Person the Prophet David also speaks: “From my mother’s womb Thou art my God:” showing clearly that He who was Lord and man was never separate from God: in whom even in the Virgin’s womb the fulness of the Godhead dwelt. …
