Proverbs 8:35

Unless, therefore, we obtain not simply determination of will, which is freely turned in this direction and that, and has its place amongst those natural goods which a bad man may use badly; but also a good will, which has its place among those goods of which it is impossible to make a bad use: unless the impossibility is given to us from God, I know not how to defend what is said: “What hast thou that thou didst not receive?” For if we have from God a certain free will, which may still be either good or bad; but the good will comes from ourselves; then that which comes from ourselves is better than that which comes from Him. But inasmuch as it is the height of absurdity to say this, they ought to acknowledge that we attain from God even a good will. …

“We maintain,” says he, “that men are the work of God, and that no one is forced unwillingly by His power either into evil or good, but that man does either good or ill of his own will; but that in a good work he is always assisted by God’s grace, while in evil he is incited by the suggestions of the devil.” To this I answer, that men, in so far as they are men, are the work of God; but in so far as they are sinners, they are under the devil, unless they are plucked from thence by Him who became the Mediator between God and man, for no other reason than because He could not be a sinner from men. And that no one is forced by God’s power unwillingly either into evil or good, but that when God forsakes a man, he deservedly goes to evil, and that when God assists, without deserving he is converted to good. …

Moreover, that, in opposition to the Manicheans, they praise free will, making use of the prophetic testimony, “If ye shall be willing and will hear me, ye shall eat what is good in the land; but if ye shall be unwilling and will not hear me, the sword shall consume you:” what advantage is this to them, when, indeed, it is not so much against the Manicheans that they are maintaining, as against the catholics that they are extolling, free will? For they wish what is said, “If ye be willing and will hear me,” to be so understood, as if in the preceding will itself were the merit of the grace that follows; and thus grace were no more grace, seeing that it is not free when it is rendered as a debt. …

What does it profit them, that in the praise of that same free will “they say that grace assists the good purpose of every one”? This would be received without scruple as being said in a catholic spirit, if they did not attribute merit to the good purpose, to which merit now a wage is paid of debt, not according to grace, but would understand and confess that even that very good purpose, which the grace which follows assists could not have been in the man if grace had not preceded it. For how is there a good purpose in a man without the mercy of God first, since it is that very good will which is prepared by the Lord? But when they had said this, “that grace also assists every one’s good purpose,” and presently added, “yet does not infuse the love of virtue into a resisting heart,” it might be fitly understood, if it were not said by those whose meaning is known. …

The Pelagians think that they know something great when they assert that “God would not command what He knew could not be done by man.” Who can be ignorant of this? But God commands some things which we cannot do, in order that we may know what we ought to ask of Him. For this is faith itself, which obtains by prayer what the law commands. He, indeed, who said, “If thou wilt, thou shalt keep the commandments,” did in the same book of Ecclesiasticus afterwards say, “Who shall give a watch before my mouth, and a seal of wisdom upon my lips, that I fall not suddenly thereby, and that my tongue destroy me not.” Now he had certainly heard and received these commandments: “Keep thy tongue from evil, and thy lips from speaking guile.” Forasmuch, then, as what he said is true: “If thou wilt, thou shalt keep the commandments,” why does he want a watch to be given before his mouth, like him who sa …

Here, if I am asked why God should not have given them perseverance to whom He gave that love by which they might live Christianly, I answer that I do not know. For I do not speak arrogantly, but with acknowledgment of my small measure, when I hear the apostle saying, “O man, who art thou that repliest against God?” and, “O the depth of the riches of the wisdom and knowledge of God! how unsearchable are His judgments, and His ways untraceable!” So far, therefore, as He condescends to manifest His judgments to us, let us give thanks; but so far as He thinks fit to conceal them, let us not murmur against His counsel, but believe that this also is the most wholesome for us. But whoever you are that are hostile to His grace, and thus ask, what do you yourself say? it is well that you do not deny yourself to be a Christian and boast of being a catholic. …
