Tertullian

“ 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 ”

“ Since they are unwilling to allow that the Son is a distinct Person, second from the Father, lest, being thus second, He should cause two Gods to be spoken of, we have shown above [16] that Two are actually described in Scripture as God and Lord. And to prevent their being offended at this fact, we give a reason why they are not said to be two Gods and two Lords, but that they are two as Father and Son ”

“ And if I am not mistaken, there is also another passage in which it is written: “By the Word of the Lord were the heavens made, and all the hosts of them by His Spirit.” [7] Now this Word, the Power of God and the Wisdom of God, must be the very Son of God. So that, if (He did) all things by the Son, He must have stretched out the heavens by the Son, and so not have stretched them out alone, except in the sense in which He is “alone” (and apart) from all other gods. ”
