Introductory to Proverbs 8:22, that the Son is not a Creature. Arianformula, a creature but not as one of the creatures; but each creature is unlike all other creatures; and no creature can create. The Word then differs from all creatures in that in which they, though otherwise differing, all agree together, as creatures; viz. in being an efficient cause; in being the one medium or instrumental agent in creation; moreover in being the revealer of the Father; and in being the object of worship
For how, if, as you hold, He has come of nothing, is He able to frame things that are nothing into being? Or if He, a creature, withal frames a creature, the same will be conceivable in the case of every creature, viz. the power to frame others. And if this pleases you, what is the need of the Word, seeing that things inferior can be brought to be by things superior? Or at all events, every thing that is brought to be could have heard in the beginning God's words, 'Become' and 'be made,' and so would have been framed. But this is not so written, nor could it be. For none of things which are brought to be is an efficient cause, but all things were made through the Word: who would not have wrought all things, were He Himself in the number of the creatures. For neither would the Angels be able to frame, since they too are creatures, though Valentinus, and Marcion, and Basilides think so, and you are their copyists; nor will the sun, as being a creature, ever make what is not into what is; nor will man fashion man, nor stone devise stone, nor wood give growth to wood. But God is He who fashions man in the womb, and fixes the mountains, and makes wood grow; whereas man, as being capable of science, puts together and arranges that material, and works things that are, as he has learned; and is satisfied if they are but brought to be, and being conscious of what his nature is, if he needs anything, knows to ask it of God.
22. If then God also wrought and compounded out of materials, this indeed is a gentile thought, according to which God is an artificer and not a Maker, but yet even in that case let the Word work the materials, at the bidding and in the service of God. But if He calls into existence things which existed not by His proper Word, then the Word is not in the number of things non-existing and called; or we have to seek another Word, through whom He too was called; for by the Word the things which were not have come to be. And if through Him He creates and makes, He is not Himself of things created and made; but rather He is the Word of the Creator God and is known from the Father's works which He Himself works, to be 'in the Father and the Father in Him,' and 'He that has seen Him has seen the Father,' because the Son's Essence is proper to the Father, and He in all points like Him. How then does He create through Him, unless it be His Word and His Wisdom? And how can He be Word and Wisdom, unless He be the proper offspring of His Essence, and did not come to be, as others, out of nothing? And whereas all things are from nothing, and are creatures, and the Son, as they say, is one of the creatures too and of things which once were not, how does He alone reveal the Father, and none else but He know the Father? For could He, a work, possibly know the Father, then must the Father be also known by all according to the proportion of the measures of each: for all of them are works as He is. But if it be impossible for things originate either to see or to know, for the sight and the knowledge of Him surpasses all (since God Himself says, 'No one shall see My face and live '), yet the Son has declared, 'No one knows the Father, save the Son,' therefore the Word is different from all things originate, in that He alone knows and alone sees the Father, as He says, 'Not that any one has seen the Father, save He that is from the Father,' and 'no one knows the Father save the Son,' though Arius think otherwise. How then did He alone know, except that He alone was proper to Him? And how proper, if He were a creature, and not a true Son from Him? (For one must not mind saying often the same thing for religion's sake.) Therefore it is irreligious to think that the Son is one of all things; and blasphemous and unmeaning to call Him 'a creature, but not as one of the creatures, and a work, but not as one of the works, an offspring, but not as one of the offsprings.' for how not as one of these, if, as they say, He was not before His generation? For it is proper to the creatures and works not to be before their origination, and to subsist out of nothing, even though they excel other creatures in glory; for this difference of one with another will be found in all creatures, which appears in those which are visible.
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 shows Him to be His own proper and only Son, saying, 'You are 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. For if He was worshipped as excelling them in glory, each of things subservient ought to worship what excels itself. But this is not the case; for creature does not worship creature, but servant Lord, and creature God. Thus Peter the Apostle hinders Cornelius who would worship him, saying, 'I myself also am a man.' And an Angel, when John would worship him in the Apocalypse, hinders him, saying, 'See thou do it not; for I am your fellow-servant, and of your brethren the Prophets, and of them that keep the sayings of this book: worship God.' Therefore to God alone appertains worship, and this the very Angels know, that though they excel other beings in glory, yet they are all creatures and not to be worshipped, but worship the Lord. Thus Manoah, the father of Samson, wishing to offer sacrifice to the Angel, was thereupon hindered by him, saying, 'Offer not to me, but to God. ' On the other hand, the Lord is worshipped even by the Angels; for it is written, 'Let all the Angels of God worship Him;' and by all the Gentiles, as Isaiah says, 'The labour of Egypt and merchandize of Ethiopia and of the Sabeans, men of stature, shall come over unto you, and they shall be your servants;' and then, 'they shall fall down unto you, and shall make supplication unto you, saying, Surely God is in you, and there is none else, there is no God.' And He accepts His disciples' worship, and certifies them who He is, saying, 'Call ye Me not Lord and Master? And you say well, for so I am.' And when Thomas said to Him, 'My Lord and my God,' He allows his words, or rather accepts him instead of hindering him. For He is, as the other Prophets declare, and David says in the Psalm, 'the Lord of hosts, the Lord of Sabaoth,' which is interpreted, 'the Lord of Armies,' and God True and Almighty, though the Arians burst at the tidings.
24. But He had not been thus worshipped, nor been thus spoken of, were He a creature merely. But now since He is not a creature, but the proper offspring of the Essence of that God who is worshipped, and His Son by nature, therefore He is worshipped and is believed to be God, and is Lord of armies, and in authority, and Almighty, as the Father is; for He has said Himself, 'All things that the Father has, are Mine.' For it is proper to the Son, to have the things of the Father, and to be such that the Father is seen in Him, and that through Him all things were made, and that the salvation of all comes to pass and consists in Him.
