Arian argument: “If there never was, when the Son was not, but He is eternal, and coexists with the Father, you call Him no more the Father’s Son, but brother”
Answer: For the Father and the Son were not generated from some pre-existing origin, that we may account Them brothers, but the Father is the Origin of the Son and begat Him; and the Father is Father, and not born the Son of any; and the Son is Son, and not brother. Further, if He is called the eternal offspring of the Father, He is rightly so called. For never was the essence of the Father imperfect, that what is proper to it should be added afterwards; nor, as man from man, has the Son been begotten, so as to be later than His Father’s existence, but He is God’s offspring, and as being proper Son of God, who is ever, He exists eternally … God’s offspring is eternal, for His nature is ever perfect.
Son is … Word, and Wisdom, and Radiance; …in maintaining ‘Once the Son was not,’ [the Arians] rob God of His Word, like plunderers, and openly predicate of Him that He was once without His proper Word and Wisdom, and that the Light was once without radiance, and the Fountain was once barren and dry. For though they pretend alarm at the name of time, because of those who reproach them with it, and say, that He was before times, yet whereas they assign certain intervals, in which they imagine He was not, they are most irreligious still, as equally suggesting times, and imputing to God an absence of Reason.[1]
Arian Argument: “If the Son is the Father’s offspring and Image, and is like in all things to the Father, then it necessarily holds that as He is begotten, so He begets, and He too becomes father of a son.”
Answer: If then God be as man, let Him become also a parent as man, so that His Son should be father of another, and so in succession one from another, till the series they imagine grows into a multitude of gods. But if God be not as man, as He is not, we must not impute to Him the attributes of man. For brutes and men, after a Creator has begun them, are begotten by succession; and the son, having been begotten of a father who was a son, becomes accordingly in his turn a father to a son, in inheriting from his father that by which he himself has come to be. Hence in such instances there is not, properly speaking, either father or son, nor do the father and the son stay in their respective characters, for the son himself becomes a father, being son of his father, but father of his son. But it is not so in the Godhead; for not as man is God; for the Father is not from a father; therefore doth He not beget one who shall become a father; nor is the Son from effluence of the Father, nor is He begotten from a father that was begotten; therefore neither is He begotten so as to beget. Thus it belongs to the Godhead alone, that the Father is properly father, and the Son properly son, and in Them, and Them only, does it hold that the Father is ever Father and the Son ever Son.
…
For in this rather is He shewn to be the Father’s Expression and Image, remaining what He is and not changing, but thus receiving from the Father to be one and the same. If then the Father change, let the Image change; for so is the Image and Radiance in its relation towards Him who begat It. But if the Father is unalterable, and what He is that He continues, necessarily does the Image also continue what He is, and will not alter. Now He is Son from the Father; therefore He will not become other than is proper to the Father’s essence.[2]
