After expounding the high estate of the Almighty, the Eternity of the Son, and the phrase being made obedient, he shows the folly of Eunomius in his assertion that the Son did not acquire His sonship by obedience
What, moreover, is the high estate of the Almighty in which Eunomius affirms that the Son has no share? Let those, then, who are wise in their own eyes, and prudent in their own sight, utter their groundling opinions— they who, as the prophet says, “speak out of the ground.” But let us who reverence the Word and are disciples of the Truth, or rather who profess to be so, not leave even this assertion unsifted. We know that of all the names by which Deity is indicated some are expressive of the Divine majesty, employed and understood absolutely, and some are assigned with reference to the operations over us and all creation. For when the Apostle says “Now to the immortal, invisible, only wise God,” and the like, by these titles he suggests conceptions which represent to us the transcendent power, but when God is spoken of in the Scriptures as gracious, merciful, full of pity, true, good, Lord, Physician, Shepherd, Way, Bread, Fountain, King, Creator, Artificer, Protector, Who is over all and through all, Who is all in all, these and similar titles contain the declaration of the operations of the Divine loving-kindness in the creation. Those then who enquire precisely into the meaning of the term “Almighty” will find that it declares nothing else concerning the Divine power than that operation which controls created things and is indicated by the word “Almighty,” stands in a certain relation to something. For as He would not be called a Physician, save on account of the sick, nor merciful and gracious, and the like, save by reason of one who stood in need of grace and mercy, so neither would He be styled Almighty, did not all creation stand in need of one to regulate it and keep it in being. As, then, He presents Himself as a Physician to those who are in need of healing, so He is Almighty over one who has need of being ruled: and just as “they that are whole have no need of a physician,” so it follows that we may well say that He Whose nature contains in it the principle of unerring and unwavering rectitude does not, like others, need a ruler over Him. Accordingly, when we hear the name “Almighty,” our conception is this, that God sustains in being all intelligible things as well as all things of a material nature. For this cause He sits upon the circle of the earth, for this cause He holds the ends of the earth in His hand, for this cause He “metes out leaven with the span, and measures the waters in the hollow of His hand”; for this cause He comprehends in Himself all the intelligible creation, that all things may remain in existence controlled by His encompassing power. Let us enquire, then, Who it is that “works all in all.” Who is He Who made all things, and without Whom no existing thing does exist? Who is He in Whom all things were created, and in Whom all things that are have their continuance? In Whom do we live and move and have our being? Who is He Who has in Himself all that the Father has? Does what has been said leave us any longer in ignorance of Him Who is “God over all,” Who is so entitled by S. Paul—our Lord Jesus Christ, Who, as He Himself says, holding in His hand “all things that the Father has,” assuredly grasps all things in the all-containing hollow of His hand and is sovereign over what He has grasped, and no man takes from the hand of Him Who in His hand holds all things? If, then, He has all things, and is sovereign over that which He has, why is He Who is thus sovereign over all things something else and not Almighty? If heresy replies that the Father is sovereign over both the Son and the Holy Spirit, let them first show that the Son and the Holy Spirit are of mutable nature, and then over this mutability let them set its ruler, that by the help implanted from above, that which is so overruled may continue incapable of turning to evil. If, on the other hand, the Divine nature is incapable of evil, unchangeable, unalterable, eternally permanent, to what end does it stand in need of a ruler, controlling as it does all creation, and itself by reason of its immutability needing no ruler to control it? For this cause it is that at the name of Christ “every knee bows, of things in heaven, and things in earth, and things under the earth.” For assuredly every knee would not thus bow, did it not recognize in Christ Him Who rules it for its own salvation. But to say that the Son came into being by the goodness of the Father is nothing else than to put Him on a level with the meanest objects of creation. For what is there that did not arrive at its birth by the goodness of Him Who made it? To what is the formation of mankind ascribed? To the badness of its Maker, or to His goodness? To what do we ascribe the generation of animals, the production of plants and herbs? There is nothing that did not take its rise from the goodness of Him Who made it. A property, then, which reason discerns to be common to all things, Eunomius is so kind as to allow to the Eternal Son! But that He did not share His essence or His estate with the Father— these assertions and the rest of his verbiage I have refuted in anticipation, when dealing with his statements concerning the Father, and shown that he has hazarded them at random and without any intelligible meaning. For not even in the case of us who are born one of another is there any division of essence. The definition expressive of essence remains in its entirety in each, in him that begets and in him who is begotten, without admitting diminution in him who begets, or augmentation in him who is begotten. But to speak of division of estate or sovereignty in the case of Him Who has all things whatsoever that the Father has, carries with it no meaning, unless it be a demonstration of the propounder's impiety. It would therefore be superfluous to entangle oneself in such discussions, and so to prolong our treatise to an unreasonable length. Let us pass on to what follows.
“Glorified,” he says, “by the Father before the worlds.” The word of truth has been demonstrated, confirmed by the testimony of its adversaries. For this is the sum of our faith, that the Son is from all eternity, being glorified by the Father: for “before the worlds” is the same in sense as “from all eternity,” seeing that prophecy uses this phrase to set forth to us God's eternity, when it speaks of Him as “He that is from before the worlds.” If then to exist before the worlds is beyond all beginning, he who confers glory on the Son before the worlds, does thereby assert His existence from eternity before that glory: for surely it is not the non-existent, but the existent which is glorified. Then he proceeds to plant for himself the seeds of blasphemy against the Holy Spirit; not with a view to glorify the Son, but that he may wantonly outrage the Holy Ghost. For with the intention of making out the Holy Spirit to be part of the angelic host, he throws in the phrase “glorified eternally by the Spirit, and by every rational and generated being,” so that there is no distinction between the Holy Spirit and all that comes into being; if, that is, the Holy Spirit glorifies the Lord in the same sense as all the other existences enumerated by the prophet, “angels and powers, and the heaven of heavens, and the water above the heavens, and all the things of earth, dragons, deeps, fire and hail, snow and vapour, wind of the storm, mountains and all hills, fruitful trees and all cedars, beasts and all cattle, worms and feathered fowls.” If, then, he says, that along with these the Holy Spirit also glorifies the Lord, surely his God-opposing tongue makes out the Holy Spirit Himself also to be one of them.
