Chapter 6 [IV.]--God's Grace to Be Maintained Against the Pelagians; The Pelagian Heresy Not an Old One.
It is, however, to be feared lest all these and similar testimonies of Holy Scripture (and undoubtedly there are a great many of them), in the maintenance of free will, be understood in such a way as to leave no room for God's assistance and grace in leading a godly life and a good conversation, to which the eternal reward is due; and lest poor wretched man, when he leads a good life and performs good works (or rather thinks that he leads a good life and performs good works), should dare to glory in himself and not in the Lord, and to put his hope of righteous living in himself alone; so as to be followed by the prophet Jeremiah's malediction when he says, "Cursed is the man who has hope in man, and maketh strong the flesh of his arm, and whose heart departeth from the Lord." [2995] Understand, my brethren, I pray you, this passage of the prophet. Because the prophet did not say, "Cursed is the man who has hope in his own self," it might seem to some that the passage, "Cursed is the man who has hope in man," was spoken to prevent man having hope in any other man but himself. In order, therefore, to show that his admonition to man was not to have hope in himself, after saying, "Cursed is the man who has hope in man," he immediately added, "And maketh strong the flesh of his arm." He used the word "arm" to designate power in operation. By the term "flesh," however, must be understood human frailty. And therefore he makes strong the flesh of his arm who supposes that a power which is frail and weak (that is, human) is sufficient for him to perform good works, and therefore puts not his hope in God for help. This is the reason why he subjoined the further clause, "And whose heart departeth from the Lord." Of this character is the Pelagian heresy, which is not an ancient one, but has only lately come into existence. Against this system of error there was first a good deal of discussion; then, as the ultimate resource, it was referred to sundry episcopal councils, the proceedings of which, not, indeed, in every instance, but in some, I have despatched to you for your perusal. In order, then, to our performance of good works, let us not have hope in man, making strong the flesh of our arm; nor let our heart ever depart from the Lord, but let it say to him, "Be Thou my helper; forsake me not, nor despise me, O God of my salvation."

Chapter 7.--Grace is Necessary Along with Free Will to Lead a Good Life.
Therefore, my dearly beloved, as we have now proved by our former testimonies from Holy Scripture that there is in man a free determination of will for living rightly and acting rightly; so now let us see what are the divine testimonies concerning the grace of God, without which we are not able to do any good thing. And first of all, I will say something about the very profession which you make in your brotherhood. Now your society, in which you are leading lives of continence, could not hold together unless you despised conjugal pleasure. Well, the Lord was one day conversing on this very topic, when His disciples remarked to Him, "If such be the case of a man with his wife, it is not good to marry." He then answered them, "All men cannot receive this saying, save they to whom it is given." [2997] And was it not to Timothy's free will that the apostle appealed, when he exhorted him in these words: "Keep thyself continent"? [2998] He also explained the power of the will in this matter when He said, "Having no necessity, but possessing power over his own will, to keep his virgin." [2999] And yet "all men do not receive this saying, except those to whom the power is given." Now they to whom this is not given either are unwilling or do not fulfil what they will; whereas they to whom it is given so will as to accomplish what they will. In order, therefore, that this saying, which is not received by all men, may yet be received by some, there are both the gift of God and free will.
