Delusional. Did Calvin teach the will was free? Augustine insisted on it.
Augustine uses the term "free will" in two different ways. In the sense of the unbeliever, it is free only to sin. In the sense of the believer, it is now free to do good. This is his response to the Christian monks who wrongly interpreted his teachings as encouraging inaction on the part of the Christian. Augustine says that we "we walk, we do, we obey" with our will, but this itself is only the evidence of God's grace making us to walk, to do, and to obey. It is God who makes us good, not we ourselves:
“Can you say, ‘We will first walk in His righteousness, and will observe His judgments, and will act in a worthy way, so that He will give His grace to us’? But what good would you evil people do? And how would you do those good things, unless you were yourselves good? But Who causes people to be good? Only He Who said, ‘And I will visit them to make them good,’ and, ‘I will put my Spirit within you, and will cause you to walk in my righteousness, and to observe my judgments, and do them’ (Ezek.36:27). Are you asleep? Can’t you hear Him saying, ‘I will cause you to walk, I will make you to observe,’ lastly, ‘I will make you to do’? Really, are you still puffing yourselves up? We walk, true enough, and we observe, and we do; but it is God Who He makes us to walk, to observe, to do. This is the grace of God making us good; this is His mercy going before us.” Augustine - Against Two Letters of the Pelagians, 4:15
“All our good merits are only wrought in us by grace, and -when God crowns our merits, he crowns nothing but his own gifts. (Augustine, Letter 194)
“Have just men, then, no merits? Certainly they have, because they are righteous. But they were not made righteous by merits. For they are made righteous when they are justified, but as the apostle says, they are justified freely by his grace.” (Ibid)
The difference between the man who falls away, by the way, and the man who remains in the faith, is entirely God's grace. In the one, He chooses to give the gift of preserverence, in the other, He does not.
“I assert, therefore, that the perseverance by which we persevere in Christ even to the end is the gift of God; and I call that the end by which is finished that life wherein alone there is peril of falling.” (Augustine, On the Perseverance of the Saints)
“But of such as these [the Elect] none perishes, because of all that the Father has given Him, He will lose none. John 6:39 Whoever, therefore, is of these does not perish at all; nor was any who perishes ever of these. For which reason it is said, They went out from among us, but they were not of us; for if they had been of us, they would certainly have continued with us. John 2:19”. (Augustine, Treatise on the Predestination of the Saints)
Augustine did teach Baptismal regeneration, but his solution with the problem of apostates was this: That the elect receive the gift of preserverence, while the apostates, like Judas, must inevitably fall away, since they were never of the elect. It is only grace which causes man to differ, and not their merits.
“For who makes thee to differ, and what has thou that thou hast not received?” (1 Cor. iv. 7). Our merits therefore do not cause us to differ, but grace. For if it be merit, it is a debt; and if it be a debt, it is not gratuitous; and if it be not gratuitous, it is not grace. (Augustine, Sermon 293)
Furthermore, Augustine teaches that God can change the will of man at any time, and if He does it not, it is in justice, and if He does it, it is in mercy. All of this is exactly our teaching:
“And, moreover, who will be so foolish and blasphemous as to say that God cannot change the evil wills of men, whichever, whenever, and wheresoever He chooses, and direct them to what is good? But when He does this He does it of mercy; when He does it not, it is of justice that He does it not for “He has mercy on whom He will have mercy, and whom He will He hardens.” And when the apostle said this, he was illustrating the grace of God, in connection with which he had just spoken of the twins in the womb of Rebecca, who “being not yet born, neither having done any good or evil that the purpose of God according to election might stand, not of works, but of Him that calls, it was said unto her, The elder shall serve the younger.” And in reference to this matter he quotes another prophetic testimony: “Jacob have I loved, but Esau have I hated.” But perceiving how what he had said might affect those who could not penetrate by their understanding the depth of this grace: “What shall we say then?” he says: “Is there unrighteousness with God? God forbid.” For it seems unjust that, in the absence of any merit or demerit, from good or evil works, God should love the one and hate the other. Now, if the apostle had wished us to understand that there were future good works of the one, and evil works of the other, which of course God foreknew, he would never have said, not of works, but, of future works, and in that way would have solved the difficulty, or rather there would then have been no difficulty to solve. As it is, however, after answering, God forbid; that is, God forbid that there should be unrighteousness with God; he goes on to prove that there is no unrighteousness in God’s doing this, and says: “For He says to Moses, I will have mercy on whom I will have mercy, and I will have compassion on whom I will have compassion.” “ (Augustine, The Enchiridion on Faith, Hope and Love, Chapter 98. Predestination to Eternal Life is Wholly of God’s Free Grace.)
“But that world which God is in Christ reconciling unto Himself, which is saved by Christ, and has all its sins freely pardoned by Christ, has been chosen out of the world that is hostile, condemned, and defiled. For out of that mass, which has all perished in Adam, are formed the vessels of mercy, whereof that world of reconciliation is composed, that is hated by the world which belongeth to the vessels of wrath that are formed out of the same mass and fitted to destruction. Finally, after saying, “If ye were of the world, the world would love its own,” He immediately added, “But because ye are not of the world, but I have chosen you out of the world, therefore the world hateth you.” And so these men were themselves also of that world, and, that they might no longer be of it, were chosen out of it, through no merit of their own, for no good works of theirs had preceded; and not by nature, which through free-will had become totally corrupted at its source: but gratuitously, that is, of actual grace. For He who chose the world out of the world, effected for Himself, instead of finding, what He should choose: for “there is a remnant saved according to the election of grace. And if by grace,” he adds, “then is it no more of works: otherwise grace is no more grace.”” (Tractates on the Gospel of John, 15:17-19)
For one final blow, note Augustine's interpretation of I Tim. 2:4: “Who Will Have All Men to Be Saved”. This passage, and others like it, are usually applied by the Papists to prove that grace is universally given, and that what makes men to differ is their rejection and disobedience.
“Or, it is said, “Who will have all men to be saved;” not that there is no man whose salvation He does not will (for how, then, explain the fact that He was unwilling to work miracles in the presence of some who, He said, would have repented if He had worked them?), but that we are to understand by “all men,” the human race in all its varieties of rank and circumstances,—kings, subjects; noble, plebeian, high, low, learned, and unlearned; the sound in body, the feeble, the clever, the dull, the foolish, the rich, the poor, and those of middling circumstances; males, females, infants, boys, youths; young, middle-aged, and old men; of every tongue, of every fashion, of all arts, of all professions, with all the innumerable differences of will and conscience, and whatever else there is that makes a distinction among men. For which of all these classes is there out of which God does not will that men should be saved in all nations through His only-begotten Son, our Lord, and therefore does save them; for the Omnipotent cannot will in vain, whatsoever He may will? Now the apostle had enjoined that prayers should be made for all men, and had especially added, “For kings, and for all that are in authority,” who might be supposed, in the pride and pomp of worldly station, to shrink from the humility of the Christian faith. Then saying, “For this is good and acceptable in the sight of God our Saviour,” that is, that prayers should be made for such as these, he immediately adds, as if to remove any ground of despair, “Who will have all men to be saved, and to come unto the knowledge of the truth” [I Tim. 2:1-4]. God, then, in His great condescension has judged it good to grant to the prayers of the humble the salvation of the exalted; and assuredly we have many examples of this. Our Lord, too, makes use of the same mode of speech in the Gospel, when He says to the Pharisees: “Ye tithe mint, and rue, and every herb” [Luke 11:42]. For the Pharisees did not tithe what belonged to others, nor all the herbs of all the inhabitants of other lands. As, then, in this place we must understand by “every herb,” every kind of herbs, so in the former passage we may understand by “all men,” every sort of men. And we may interpret it in any other way we please, so long as we are not compelled to believe that the omnipotent God has willed anything to be done which was not done: for setting aside all ambiguities, if “He hath done all that He pleased in heaven and in earth” [Ps. 115:3]. as the psalmist sings of Him, He certainly did not will to do anything that He hath not done.” (Augustine, Enchiridion on Faith, Hope and Love, Ch. 103. Interpretation of the Expression in I Tim. 2:4: “Who Will Have All Men to Be Saved”.)
