Isaias 40:13

Then I said, “Isaiah thus foretold John’s forerunning: ‘And Hezekiah said to Isaiah, Good is the word of the Lord which He spake: Let there be peace and righteousness in my days.’ And, ‘Encourage the people; ye priests, speak to the heart of Jerusalem, and encourage her, because her humiliation is accomplished. Her sin is annulled; for she has received of the Lord’s hand double for her sins. A voice of one crying in the wilderness, Prepare the ways of the Lord; make straight the paths of our God. Every valley shall be filled up, and every mountain and hill shall be brought low: and the crooked shall be made straight, and the rough way shall be plain ways; and the glory of the Lord shall be seen, and all flesh shall see the salvation of God: for the Lord hath spoken it. …

he drew the thought from the following: “Who hath known the mind of the Lord , or who was His counsellor?” Hesiod, too, agrees with what is said above, in what he writes:

In the Creator, however, the two courses were perfectly compatible, both the predestination before the ages and the revelation at the end thereof, because that which He both fore-ordained and revealed He also in the intermediate space of time announced by the pre-ministration of figures, and symbols, and allegories. But because (the apostle) subjoins, on the subject of our glory, that “none of the princes of this world knew it, for had they known it they would not have crucified the Lord of glory,” the heretic argues that the princes of this world crucified the Lord (that is, the Christ of the rival god) in order that this blow might even recoil on the Creator Himself. …

As our heretic is so fond of his pruning-knife, I do not wonder when syllables are expunged by his hand, seeing that entire pages are usually the matter on which he practises his effacing process. The apostle declares that to himself, “less than the least of all saints, was the grace given” of enlightening all men as to “what was the fellowship of the mystery, which during the ages had been hid in God, who created all things.” The heretic erased the preposition in , and made the clause run thus: (“what is the fellowship of the mystery) which hath for ages been hidden from the God who created all things.” The falsification, however, is flagrantly absurd. …

The object of the apostle in thus writing was not to introduce the diversity of nature, but to exhibit the notion of Father and of Son as unconfounded. That the phrases are not opposed to one another and do not, like squadrons in war marshalled one against another, bring the natures to which they are applied into mutual conflict, is perfectly plain from the passage in question. The blessed Paul brings both phrases to bear upon one and the same subject, in the words “of him and through him and to him are all things.” That this plainly refers to the Lord will be admitted even by a reader paying but small attention to the meaning of the words. …

90. But if you really consider whence the passage is taken you will have no doubt that it is said of the Son. For the Apostle says, according to the prophecy of Isaiah, “Who hath known the mind of the Lord, or who hath been His counsellor?” And he adds: “For of Him and in Him are all things.” Which Isaiah had said of the Artificer of all, as you read: “Who hath measured out the water with his hand, and the heaven with a span, and all the earth with his closed hand? Who hath placed the mountains in scales and the hills in a balance? Who hath known the mind of the Lord, or who hath been His counsellor?”

40. Aye, let some one show what there is that the Son of God cannot do. Who was His helper, when He made the heavens, Who, when He laid the foundations of the world? Had He any need of a helper to set men free, Who needed none in constituting angels and principalities?
