Texts explained; Sixthly, Proverbs 8:22. Proverbs are of a figurative nature, and must be interpreted as such. We must interpret them, and in particular this passage, by the Regula Fidei. 'He created me' not equivalent to 'I am a creature.' Wisdom a creature so far forth as Its human body. Again, if He is a creature, it is as 'a beginning of ways,' an office which, though not an attribute, is a consequence, of a higher and divine nature. And it is 'for the works,' which implied the works existed, and therefore much more He, before He was created. Also 'the Lord' not the Father 'created' Him, which implies the creation was that of a servant
50 Your famous assertion then, that the Son is a creature, is not true, but is your fantasy only; nay Solomon convicts you of having many times slandered him. For he has not called Him creature, but God's Offspring and Wisdom, saying, 'God in Wisdom established the earth,' and 'Wisdom built her an house. ' And the very passage in question proves your irreligious spirit; for it is written, 'The Lord created me a beginning of His ways for His works.' Therefore if He is before all things, yet says 'He created me' (not 'that I might make the works,' but) 'for the works,' unless 'He created' relates to something later than Himself, He will seem later than the works, finding them on His creation already in existence before Him, for the sake of which He is also brought into being. And if so, how is He before all things notwithstanding? And how were all things made through Him and consist in Him? For behold, you say that the works consisted before Him, for which He is created and sent. But it is not so; perish the thought! false is the supposition of the heretics. For the Word of God is not creature but Creator; and says in the manner of proverbs, 'He created me' when He put on created flesh. And something besides may be understood from the passage itself; for, being Son and having God for His Father, for He is His proper Offspring, yet here He names the Father Lord; not that He was servant, but because He took the servant's form. For it became Him, on the one hand being the Word from the Father, to call God Father: for this is proper to son towards father; on the other, having come to finish the work, and taken a servant's form, to name the Father Lord. And this difference He Himself has taught by an apt distinction, saying in the Gospels, 'I thank You, O Father,' and then, 'Lord of heaven and earth.' For He calls God His Father, but of the creatures He names Him Lord; as showing clearly from these words, that, when He put on the creature, then it was He called the Father Lord. For in the prayer of David the Holy Spirit marks the same distinction, saying in the Psalms, 'Give Your strength unto Your Child, and help the Son of Your handmaid. ' For the natural and true child of God is one, and the sons of the handmaid, that is, of the nature of things originate, are other. Wherefore the One, as Son, has the Father's might; but the rest are in need of salvation.
51. (But if, because He was called child, they idly talk, let them know that both Isaac was named Abraham's child, and the son of the Shunamite was called young child.) Reasonably then, we being servants, when He became as we, He too calls the Father Lord, as we do; and this He has so done from love to man, that we too, being servants by nature, and receiving the Spirit of the Son, might have confidence to call Him by grace Father, who is by nature our Lord. But as we, in calling the Lord Father, do not deny our servitude by nature (for we are His works, and it is 'He that has made us, and not we ourselves '), so when the Son, on taking the servant's form, says, 'The Lord created me a beginning of His ways,' let them not deny the eternity of His Godhead, and that 'in the beginning was the Word,' and 'all things were made by Him,' and 'in Him all things were created.
