The City of God, Volume I

by Bishop of Hippo Saint Augustine

"Pay vows to Juno: overbear
Her queenly soul with gift and prayer."[410]

In conformity with this opinion, Porphyry—expressing, however, not so much his own views as other people's—says that a good god or genius cannot come to a man unless the evil genius has been first of all propitiated, implying that the evil deities had greater power than the good; for, until they have been appeased and give place, the good can give no assistance; and if the evil deities oppose, the good can give no help; whereas the evil can do injury without the good being able to prevent them. This is not the way of the true and truly holy religion; not thus do our martyrs conquer Juno, that is to say, the powers of the air, who envy the virtues of the pious. Our heroes, if we could so call them, overcome Hêrê, not by suppliant gifts, but by divine virtues. As Scipio, who conquered Africa by his valour, is more suitably styled Africanus than if he had appeased his enemies by gifts, and so won their mercy.

22. Whence the saints derive power against demons and true purification of heart.

It is by true piety that men of God cast out the hostile power of the air which opposes godliness; it is by exorcising it, not by propitiating it; and they overcome all the temptations of the adversary by praying, not to him, but to their own God against him. For the devil cannot conquer or subdue any but those who are in league with sin; and therefore he is conquered in the name of Him who assumed humanity, and that without sin, that Himself being both Priest and Sacrifice, He might bring about the remission of sins, that is to say, might bring it about through the Mediator between God and men, the man Christ Jesus, by whom we are reconciled to God, the cleansing from sin being accomplished. For men are separated from God only by sins, from which we are in this life cleansed not by our own virtue, but by the divine compassion; through His indulgence, not through our own power. For, whatever virtue we call our own is itself bestowed upon us by His goodness. And we might attribute too much to ourselves while in the flesh, unless we lived in the receipt of pardon until we laid it down. This is the reason why there has been vouchsafed to us, through the Mediator, this grace, that we who are polluted by sinful flesh should be cleansed by the likeness of sinful flesh. By this grace of God, wherein He has shown His great compassion toward us, we are both governed by faith in this life, and, after this life, are led onwards to the fullest perfection by the vision of immutable truth.

23. Of the principles which, according to the Platonists, regulate the purification of the soul.

Even Porphyry asserts that it was revealed by divine oracles that we are not purified by any sacrifices[411] to sun or moon, meaning it to be inferred that we are not purified by sacrificing to any gods. For what mysteries can purify, if those of the sun and moon, which are esteemed the chief of the celestial gods, do not purify? He says, too, in the same place, that "principles" can purify, lest it should be supposed, from his saying that sacrificing to the sun and moon cannot purify, that sacrificing to some other of the host of gods might do so. And what he as a Platonist means by "principles," we know.[412] For he speaks of God the Father and God the Son, whom he calls (writing in Greek) the intellect or mind of the Father;[413] but of the Holy Spirit he says either nothing, or nothing plainly, for I do not understand what other he speaks of as holding the middle place between these two. For if, like Plotinus in his discussion regarding the three principal substances,[414] he wished us to understand by this third the soul of nature, he would certainly not have given it the middle place between these two, that is, between the Father and the Son. For Plotinus places the soul of nature after the intellect of the Father, while Porphyry, making it the mean, does not place it after, but between the others. No doubt he spoke according to his light, or as he thought expedient; but we assert that the Holy Spirit is the Spirit not of the Father only, nor of the Son only, but of both. For philosophers speak as they have a mind to, and in the most difficult matters do not scruple to offend religious ears; but we are bound to speak according to a certain rule, lest freedom of speech beget impiety of opinion about the matters themselves of which we speak.

24. Of the one only true principle which alone purifies and renews human nature.

Accordingly, when we speak of God, we do not affirm two or three principles, no more than we are at liberty to affirm two or three gods; although, speaking of each, of the Father, or of the Son, or of the Holy Ghost, we confess that each is God: and yet we do not say, as the Sabellian heretics say, that the Father is the same as the Son, and the Holy Spirit the same as the Father and the Son; but we say that the Father is the Father of the Son, and the Son the Son of the Father, and that the Holy Spirit of the Father and the Son is neither the Father nor the Son. It was therefore truly said that man is cleansed only by a Principle, although the Platonists erred in speaking in the plural of principles. But Porphyry, being under the dominion of these envious powers, whose influence he was at once ashamed of and afraid to throw off, refused to recognise that Christ is the Principle by whose incarnation we are purified. Indeed he despised Him, because of the flesh itself which He assumed, that He might offer a sacrifice for our purification,—a great mystery, unintelligible to Porphyry's pride, which that true and benignant Redeemer brought low by His humility, manifesting Himself to mortals by the mortality which He assumed, and which the malignant and deceitful mediators are proud of wanting, promising, as the boon of immortals, a deceptive assistance to wretched men. Thus the good and true Mediator showed that it is sin which is evil, and not the substance or nature of flesh; for this, together with the human soul, could without sin be both assumed and retained, and laid down in death, and changed to something better by resurrection. He showed also that death itself, although the punishment of sin, was submitted to by Him for our sakes without sin, and must not be evaded by sin on our part, but rather, if opportunity serves, be borne for righteousness' sake. For he was able to expiate sins by dying, because He both died, and not for sin of His own. But He has not been recognised by Porphyry as the Principle, otherwise he would have recognised Him as the Purifier. The Principle is neither the flesh nor the human soul in Christ, but the Word by which all things were made. The flesh, therefore, does not by its own virtue purify, but by virtue of the Word by which it was assumed, when "the Word became flesh and dwelt among us."[415] For, speaking mystically of eating His flesh, when those who did not understand Him were offended and went away, saying, "This is an hard saying, who can hear it?" He answered to the rest who remained, "It is the Spirit that quickeneth; the flesh profiteth nothing."[416] The Principle, therefore, having assumed a human soul and flesh, cleanses the soul and flesh of believers. Therefore, when the Jews asked Him who He was, He answered that He was the Principle.[417] And this we carnal and feeble men, liable to sin, and involved in the darkness of ignorance, could not possibly understand, unless we were cleansed and healed by Him, both by means of what we were, and of what we were not. For we were men, but we were not righteous; whereas in His incarnation there was a human nature, but it was righteous, and not sinful. This is the mediation whereby a hand is stretched to the lapsed and fallen; this is the seed "ordained by angels," by whose ministry the law also was given enjoining the worship of one God, and promising that this Mediator should come.

25. That all the saints, both under the law and before it, were justified by faith in the mystery of Christ's incarnation.
