Now, admittedly, St. Augustine
St. Augustine is an interesting kettle of fish. In his later life he retracted a lot of what he wrote on this issue but his
Enchiridion is one of his later works an in that he sets forth his views quite clearly:
Chapter 98. Predestination to Eternal Life is Wholly of God's Free Grace.
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." Now, who but a fool would think that God was unrighteous, either in inflicting penal justice on those who had earned it, or in extending mercy to the unworthy? Then he draws his conclusion: "So then it is not of him that wills, nor of him that runs, but of God that shows mercy." Thus both the twins were born children of wrath, not on account of any works of their own, but because they were bound in the fetters of that original condemnation which came through Adam. But He who said, "I will have mercy on whom I will have mercy," loved Jacob of His undeserved grace, and hated Esau of His deserved judgment. And as this judgment was due to both, the former learned from the case of the latter that the fact of the same punishment not falling upon himself gave him no room to glory in any merit of his own, but only in the riches of the divine grace; because "it is not of him that wills, nor of him that runs, but of God that shows mercy." And indeed the whole face, and, if I may use the expression, every lineament of the countenance of Scripture conveys by a very profound analogy this wholesome warning to every one who looks carefully into it, that he who glories should glory in the Lord.
Chapter 99. As God's Mercy is Free, So His Judgments are Just, and Cannot Be Gainsaid.
Now after commending the mercy of God, saying, "So it is not of him that wills, nor of him that runs, but of God that shows mercy," that he might commend His justice also (for the man who does not obtain mercy finds, not iniquity, but justice, there being no iniquity with God), he immediately adds: "For the scripture says unto Pharoah, Even for this same purpose have I raised you up, that I might show my power in you, and that my name might be declared throughout all the earth." And then he draws a conclusion that applies to both, that is, both to His mercy and His justice: "Therefore has He mercy on whom He will have mercy, and whom He will He hardens." "He has mercy" of His great goodness, "He hardens" without any injustice; so that neither can he that is pardoned glory in any merit of his own, nor he that is condemned complain of anything but his own demerit. For it is grace alone that separates the redeemed from the lost, all having been involved in one common perdition through their common origin. Now if any one, on hearing this, should say, "Why does He yet find fault? for who has resisted His will?" as if a man ought not to be blamed for being bad, because God has mercy on whom He will have mercy, and whom He will He hardens, God forbid that we should be ashamed to answer as we see the apostle answered: "Nay, but, O man, who are you that repliest against God? Shall the thing formed say to Him that formed it, Why have You made me thus? Hath not the potter power over the clay, of the same lump to make one vessel unto honor, and another unto dishonor?" Now some foolish people, think that in this place the apostle had no answer to give; and for want of a reason to render, rebuked the presumption of his interrogator. But there is great weight in this saying: "Nay, but, O man, who are you?" and in such a matter as this it suggests to a man in a single word the limits of his capacity, and at the same time does in reality convey an important reason. For if a man does not understand these matters, who is he that he should reply against God? And if he does understand them, he finds no further room for reply. For then he perceives that the whole human race was condemned in its rebellious head by a divine judgment so just, that if not a single member of the race had been redeemed, no one could justly have questioned the justice of God; and that it was right that those who are redeemed should be redeemed in such a way as to show, by the greater number who are unredeemed and left in their just condemnation, what the whole race deserved, and whither the deserved judgment of God would lead even the redeemed, did not His undeserved mercy interpose, so that every mouth might be stopped of those who wish to glory in their own merits, and that he that glories might glory in the Lord.
Chapter 103. Interpretation of the Expression in I Tim. II. 4: "Who Will Have All Men to Be Saved."
Accordingly, when we hear and read in Scripture that He "will have all men to be saved," although we know well that all men are not saved, we are not on that account to restrict the omnipotence of God, but are rather to understand the Scripture, "Who will have all men to be saved," as meaning that no man is saved unless God wills his salvation: not that there is no man whose salvation He does not will, but that no man is saved apart from His will; and that, therefore, we should pray Him to will our salvation, because if He will it, it must necessarily be accomplished. And it was of prayer to God that the apostle was speaking when he used this expression. And on the same principle we interpret the expression in the Gospel: "The true light which lights every man that comes into the world:" not that there is no man who is not enlightened, but that no man is enlightened except by Him. 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." 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: "You tithe mint, and rue, and every herb." 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 has done all that He pleased in heaven and in earth," as the psalmist sings of Him, He certainly did not will to do anything that He has not done.
