Tertullian's Exegesis of Isaiah 44:24 (Adversus Praxean 19)

"By thus attaching the Son to Himself, He becomes His own interpreter in what sense He stretched out the heavens alone, meaning alone with His Son, even as He is one with His Son. The utterance, therefore, will be in like manner the Son's, 'I have stretched out the heavens alone,' because by the Word were the heavens established. Inasmuch, then, as the heaven was prepared when Wisdom was present in the Word, and since all things were made by the Word, it is quite correct to say that even the Son stretched out the heaven alone, because He alone ministered to the Father's work. It must also be He who says, 'I am the First, and to all futurity I AM.' The Word, no doubt, was before all things. 'In the beginning was the Word'; and in that beginning He was sent forth by the Father. The Father, however, has no beginning, as proceeding from none; nor can He be seen, since He was not begotten. He who has always been alone could never have had order or rank. Therefore, if they have determined that the Father and the Son must be regarded as one and the same, for the express purpose of vindicating the unity of God, that unity of His is preserved intact; for He is one, and yet He has a Son, who is equally with Himself comprehended in the same Scriptures."
