43 Or perhaps you wish the assertion that He was created for the works to be understood in the sense that He was created on account of the works; in other words that Christ was created for the sake of performing the works. In that case He exists as a servant and a builder of the universe, and was not born the Lord of Glory; He was created for the service of forming the ages, and was not always the beloved Son and the King of the ages. But, although the general understanding of Christians contradicts this impious thought of yours, recognising that it is one thing to be created for the beginning of the ways of God and for His works, and another to be born before the ages, yet this very same passage thwarts your purpose of falsely asserting that the Lord Christ was created, on account of the formation of the universe, since it shows that God the Father is the Maker and Former of the universe, and shows it convincingly, since Christ Himself was present fashioning by the side of Him Who was forming all things.
But, while all Scripture was designed to speak of the Lord Jesus Christ as the Creator of the universe, Wisdom, to destroy all occasion for impiety, has here declared that though God the Father was the Constructor of the universe, yet itself was not absent from Him while constructing it, since it was present with Him even when He was preparing it beforehand, and that when the Father formed the universe, Wisdom also was fashioning it by the side of Him Who formed it, and was present with Him even when He prepared it.
Whence Wisdom would have us understand that it was not created on account of God's works, by the very fact that it had been present at the eternal preparation of works yet to be, and proves Scripture not to be false, by the fact that it fashioned the universe by the side of God when He formed it.
