Lastly he displays at length the folly of Eunomius, who at times speaks of the Holy Spiritas created, and as the fairest work of the Son, and at other times confesses, by the operations attributed to Him, that He is God, and thus ends the book
Let us now see further what he adds to this “sanctifying the saints.” If any one says this also of the Father and of the Son, he will speak truly. For those in whom the Holy One dwells, He makes holy, even as the Good One makes men good. And the Father, the Son, and the Holy Ghost are holy and good, as has been shown. “Acting as a guide to those who approach the mystery.” This may well be said of Apollos who watered what Paul planted. For the Apostle plants by his guidance, and Apollos, when he baptizes, waters by Sacramental regeneration, bringing to the mystery those who were instructed by Paul. Thus he places on a level with Apollos that Spirit Who perfects men through baptism. “Distributing every gift.” With this we too agree; for everything that is good is a portion of the gifts of the Holy Spirit. “Co-operating with the faithful for the understanding and contemplation of things appointed.” As he does not add by whom they are appointed, he leaves his meaning doubtful, whether it is correct or the reverse. But we will by a slight addition advance his statement so as to make it consistent with godliness. For since, whether it be the word of wisdom, or the word of knowledge, or faith, or help, or government, or anything else that is enumerated in the lists of saving gifts, “all these works that one and the self-same Spirit, dividing to every man severally as He will,” we therefore do not reject the statement of Eunomius when he says that the Spirit “co-operates with the faithful for understanding and contemplation of things appointed” by Him, because by Him all good teachings are appointed for us. “Sounding an accompaniment to those who pray.” It would be foolish seriously to examine the meaning of this expression, of which the ludicrous and meaningless character is at once manifest to all. For who is so demented and beside himself as to wait for us to tell him that the Holy Spirit is not a bell nor an empty cask sounding an accompaniment and made to ring by the voice of him who prays as it were by a blow? “Leading us to that which is expedient for us.” This the Father and the Son likewise do: for “He leads Joseph like a sheep,” and, “led His people like sheep,” and, “the good Spirit leads us in a land of righteousness.” “Strengthening us to godliness.” To strengthen man to godliness David says is the work of God; “For You are my strength and my refuge,” says the Psalmist, and “the Lord is the strength of His people,” and, “He shall give strength and power unto His people.” If then the expressions of Eunomius are meant in accordance with the mind of the Psalmist, they are a testimony to the Divinity of the Holy Ghost: but if they are opposed to the word of prophecy, then by this very fact a charge of blasphemy lies against Eunomius, because he sets up his own opinions in opposition to the holy prophets. Next he says, “Lightening souls with the light of knowledge.” This grace also the doctrine of godliness ascribes alike to the Father, to the Son, and to the Holy Ghost. For He is called a light by David, and from thence the light of knowledge shines in them who are enlightened. In like manner also the cleansing of our thoughts of which the statement speaks is proper to the power of the Lord. For it was “the brightness of the Father's glory, and the express image of His person,” Who “purged our sins.” Again, to banish devils, which Eunomius says is a property of the Spirit, this also the only-begotten God, Who said to the devil, “I charge you,” ascribes to the power of the Spirit, when He says, “If I by the Spirit of God cast out devils,” so that the expulsion of devils is not destructive of the glory of the Spirit, but rather a demonstration of His divine and transcendent power. “Healing the sick,” he says, “curing the infirm, comforting the afflicted, raising up those who stumble, recovering the distressed.” These are the words of those who think reverently of the Holy Ghost, for no one would ascribe the operation of any one of these effects to any one except to God. If then heresy affirms that those things which it belongs to none save God alone to effect, are wrought by the power of the Spirit, we have in support of the truths for which we are contending the witness even of our adversaries. How does the Psalmist seek his healing from God, saying, “Have mercy upon me, O Lord, for I am weak; O Lord, heal me, for my bones are vexed!” It is to God that Isaiah says, “The dew that is from You is healing unto them.” Again, prophetic language attests that the conversion of those in error is the work of God. For “they went astray in the wilderness in a thirsty land,” says the Psalmist, and he adds, “So He led them forth by the right way, that they might go to the city where they dwelt:” and, “when the Lord turned again the captivity of Sion.” In like manner also the comfort of the afflicted is ascribed to God, Paul thus speaking, “Blessed be God, even the Father of our Lord Jesus Christ, Who comforts us in all our tribulation.” Again, the Psalmist says, speaking in the person of God, “You called upon Me in trouble and I delivered you.” And the setting upright of those who stumble is innumerable times ascribed by Scripture to the power of the Lord: “You have thrust sore at me that I might fall, but the Lord was my help,” and “Though he fall, he shall not be cast away, for the Lord upholds him with His hand,” and “The Lord helps them that are fallen.” And to the loving-kindness of God confessedly belongs the recovery of the distressed, if Eunomius means the same thing of which we learn in prophecy, as the Scripture says, “You laid trouble upon our loins; You suffered men to ride over our heads; we went through fire and water, and You brought us out into a wealthy place.”
Thus far then the majesty of the Spirit is demonstrated by the evidence of our opponents, but in what follows the limpid waters of devotion are once more defiled by the mud of heresy. For he says of the Spirit that He “cheers on those who are contending”: and this phrase involves him in the charge of extreme folly and impiety. For in the stadium some have the task of arranging the competitions between those who intend to show their athletic vigour; others, who surpass the rest in strength and skill, strive for the victory and strip to contend with one another, while the rest, taking sides in their good wishes with one or other of the competitors, according as they are severally disposed towards or interested in one athlete or another, cheer him on at the time of the engagement, and bid him guard against some hurt, or remember some trick of wrestling, or keep himself unthrown by the help of his art. Take note from what has been said to how low a rank Eunomius degrades the Holy Spirit. For while on the course there are some who arrange the contests, and others who settle whether the contest is conducted according to rule, others who are actually engaged, and yet others who cheer on the competitors, who are acknowledged to be far inferior to the athletes themselves, Eunomius considers the Holy Spirit as one of the mob who look on, or as one of those who attend upon the athletes, seeing that He neither determines the contest nor awards the victory, nor contends with the adversary, but merely cheers without contributing at all to the victory. For He neither joins in the fray, nor does He implant the power to contend, but merely wishes that the athlete in whom He is interested may not come off second in the strife. And so Paul wrestles “against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places,” while the Spirit of power does not strengthen the combatants nor distribute to them His gifts, “dividing to every man severally as He will,” but His influence is limited to cheering on those who are engaged.
