What he means is somewhat as follows. Pharaoh was a vessel of wrath, that is, a man who by his own hard-heartedness had kindled the wrath of God. For after enjoying much long-suffering, he became no better, but remained unimproved. Wherefore he calls him not only "a vessel of wrath," but also one "fitted for destruction." That is, fully fitted indeed, but by his own proper self. For neither had God left out anything of the things likely to recover him, nor did he leave out anything of those that would ruin him, and put him beyond any forgiveness. Yet still, though God knew this, "He endured him with much long-suffering," being willing to bring him to repentance. For had He not willed this, then He would not have been thus long-suffering. But as he would not use the long-suffering in order to repentance, but fully fitted himself for wrath, He used him for the correction of others, through the punishment inflicted upon him making them better, and in this way setting forth His power. For that it is not God's wish that His power be so made known, but in another way, by His benefits, namely, and kindnesses, he had shown above in all possible ways. For if Paul does not wish to appear powerful in this way ("not that we should appear approved," he says, "but that you should do that which is honest,") [2 Corinthians 13:7], much less does God. But after that he had shown long-suffering, that He might lead to repentance, but he did not repent, He suffered him a long time, that He might display at once His goodness and His power, even if that man were not minded to gain anything from this great long-suffering. As then by punishing this man, who continued incorrigible, He showed His power, so by having pitied those who had done many sins but repented, He manifested His love toward man. But it does not say, love towards man, but glory, to show that this is especially God's glory, and for this He was above all things earnest. But in saying, "which He had afore prepared unto glory," he does not mean that all is God's doing. Since if this were so, there were nothing to hinder all men from being saved. But he is setting forth again His foreknowledge, and doing away with the difference between the Jews and the Gentiles. And on this topic again he grounds a defense of his statement, which is no small one. For it was not in the case of the Jews only that some men perished, and some were saved, but with the Gentiles also this was the case. Wherefore he does not say, all the Gentiles, but, "of the Gentiles," nor, all the Jews, but, "of the Jews." As then Pharaoh became a vessel of wrath by his own lawlessness, so did these become vessels of mercy by their own readiness to obey. For though the more part is of God, still they also have contributed themselves some little. Whence he does not say either, vessels of well-doing, or vessels of boldness (παρρησίας), but "vessels of mercy," to show that the whole is of God. For the phrase, "it is not of him that wills, nor of him that runs," even if it comes in the course of the objection, still, were it said by Paul, would create no difficulty. Because when he says, "it is not of him that wills, nor of him that runs," he does not deprive us of free-will, but shows that all is not one's own, for that it requires grace from above. For it is binding on us to will, and also to run: but to confide not in our own labors, but in the love of God toward man. And this he has expressed elsewhere. "Yet not I, but the grace which was with me." [1 Corinthians 15:10] And he well says, "Which He had afore prepared unto glory." For since they reproached them with this, that they were saved by grace, and thought to make them ashamed, he far more than sets aside this insinuation. For if the thing brought glory even to God, much more to them through whom God was glorified. But observe his forbearance, and unspeakable wisdom. For when he had it in his power to adduce, as an instance of those punished, not Pharaoh, but such of the Jews as had sinned, and so make his discourse much clearer, and show that where there were the same fathers, and the same sins, some perished, and some had mercy shown them, and persuade them not to be doubtful-minded, even if some of the Gentiles were saved, while the Jews were perishing; that he might not make his discourse irksome, the showing forth of the punishment he draws from the foreigner, so that he may not be forced to call them "vessels of wrath." But those that obtained mercy he draws from the people of the Jews. And besides, he also has spoken in a sufficient way in God's behalf, because though He knew very well that the nation was fitting itself as a vessel of destruction, still He contributed all on His part, His patience, His long-suffering, and that not merely long-suffering, but "much long-suffering;" yet still he was not minded to state it barely against the Jews. Whence then are some vessels of wrath, and some of mercy? Of their own free choice. God, however, being very good, shows the same kindness to both. For it was not those in a state of salvation only to whom He showed mercy, but also Pharaoh, as far as His part went. For of the same long-suffering, both they and he had the advantage. And if he was not saved, it was quite owing to his own will: since, as for what concerns God, he had as much done for him as they who were saved. Having then given to the question that answer which was furnished by facts, in order to give his discourse the advantage of other testimony in its favor, he introduces the prophets also making the same declarations aforetime. For Hosea, he says, of old put this in writing, as follows:
A brother asked a hermit, ‘What is humility?’ He answered, ‘To do good to them that do evil to you.’ The brother said, ‘Suppose a man cannot attain that standard, what is he to do?’ The hermit answered, ‘He should run away, and choose silence.’
Why, he means, am I telling you that you must keep peace? For I even insist upon your doing kindness. For he says, "give him to eat, and give him to drink." Then as the command he gave was a very difficult and a great one, he proceeds: "for in so doing you shall heap coals of fire upon his head." And this he said both to humble the one by fear, and to make the other more ready-minded through hope of a recompense. For he that is wronged, when he is feeble, is not so much taken with any goods of his own as with the vengeance upon the person who has pained him. For there nothing so sweet as to see an enemy chastised. What he is longing for, then, that he gives him first, and when he has let the venom go, then he again gives advice of a higher tone, saying, "Be not overcome of evil." For he knew that if the enemy were a very brute, he would not continue an enemy when he had been fed. And if the man injured be of ever so little a soul, still when feeding him and giving him to drink, he will not himself even have any farther craving for his punishment. Hence, out of confidence in the result of the action, he does not simply threaten, but even dwells largely upon the vengeance. For he did not say, "you shall take vengeance" but, "you shall heap coals of fire upon his head." Then he further declares him victor, by saying, "be not overcome of evil, but overcome evil with good." And he gives a kind of gentle hint, that one is not to do it with that intention, since cherishing a grudge still would be "being overcome of evil." But he did not say it at once, as he did not find it advisable yet. But when he had disburdened the man of his anger, then he proceeded to say, "overcome evil with good." Since this would be a victory. For the combatant is rather then the conqueror, not when he brings himself under to take the blows, but when he withdraws himself, and makes his antagonist waste his strength upon the air. And in this way he will not be struck himself, and will also exhaust the whole of the other's strength. And this takes place in regard to affronts also. For when you do affronts in return, you have the worse, not as overcome (so 1 manuscript νικηθεὶς], Sav. κινηθεὶς) by a man, but what is far more disgraceful, by the slavish passion of anger. But if you are silent, then you will conquer, and erect a trophy without a fight, and will have thousands to crown you, and to condemn the slander of falsehood. For he that replies, seems to be speaking in return as if stung. And he that is stung, gives reason to suspect that he is conscious of being guilty of what is said of him. But if you laugh at it, by your laughing you do away with the sentence against you. And if you would have a clear proof of what has been said, ask the enemy himself, when he is most vexed? When you are heated, and insult him in return? Or when you laugh at him as he insults you? And you will be told the last rather. For he too is not so much pleased with not being insulted in return, as he is vexed because his abuse was not able to gain any hold upon you. Did you never see men in a passion, how they make no great account of their own wounds, but rush on with much violence, and are worse than very wild boars for seeking the hurt of their neighbor, and look to this alone, and are more given to this than to being on their guard against getting harmed? When therefore you deprive him of that he desires most, you bereave him of everything, by holding him thus cheap, and showing him to be easy to be despised, and a child rather than a man; and you indeed have gained the reputation of a wise man, and him you invest with the character of a noisome beast. This too let us do when we are struck, and when we wish to strike, let us abstain from striking again. But, would you give a mortal blow? "Turn to him the other cheek also" [Matthew 5:39], and you will smite him with countless wounds. For they that applaud, and wonder at you, are more annoying to him than men to stone him would be; and before them, his conscience will condemn him, and will exact the greatest punishment of him, and so he will go off with a confused look as if he had been treated with the utmost rigor. And if it is the estimation of the multitude that you look for, this too you will have in larger share. And in a general way we have a kind of sympathy with those who are the sufferers; but when we also see that they do not strike (several manuscripts resist, ἀ ντιπίπτοντας) in return, but even give themselves up to it, we not only pity them, but even feel admiration for them.
Here then I find reason to lament, that we who might have things present, if we listened to Christ's Law as we should, and also attain to things to come, are cast out of both by not paying attention to what has been told us, but giving ourselves to unwarranted philosophising about them. For He has given us laws upon all these points for our good, and has shown us what makes us have a good name, what brings us to disgrace. And if it was likely to have proved His disciples ridiculous, He would not have enjoined this. But since this makes them the most notable of men namely, the not speaking ill, when we have ill spoken of us; the not doing ill when we have ill done us; this was His reason for enjoining it. But if this be so, much more the speaking of good when we have ill spoken of us, and the praising of those that insult us, and the doing good to those that plot against us, will make us so. This then was why He gave these laws. For He is careful for His own disciples, and knowing well what it is that makes little or great. If then He both cares and knows, why do you quarrel with Him, and wish to go another road? For conquering by doing ill is one of the devil's laws. Hence in the Olympic games which were celebrated to him it is so that all the competitors conquer. But in Christ's race this is not the rule about the prize, for, on the contrary, the law is for the person smitten, and not for the person smiting, to be crowned. For such is the character of His race, it has all its regulations the other way; so that it is not in the victory only, but also in the way of the victory, that the marvel is the greater. Now when things which on the other side are signs of a victory, on this side he shows to be productive of defeat, this is the power of God, this the race of Heaven, this the theatre of Angels. I know that you are warmed thoroughly now, and have become as soft as any wax, but when you have gone hence you will spew it all out. This is why I sorrow, that what we are speaking of, we do not show in our actions, and this too though we should be greatest gainers thereby. For if we let our moderation be seen, we shall be invincible to any man; and there is nobody either great or small, who will have the power of doing us any hurt. For if any one abuses you, he has not hurt you at all, but himself severely. And if again he wrong you, the harm will be with the person who does the wrong. Did you never notice that even in the courts of law those who have had wrong done them are honored, and stand and speak out with entire freedom, but those who have done the wrong, are bowed down with shame and fear? And why do I talk of evil-speaking (Sav. conj. and 5 manuscripts κακηγορίαν]) and of wrong? For were he even to whet his sword against you, and to stain his right hand in your life-blood (εἰς τὸν λαιμὸν, as p. 505), it is not you that he has done any harm to, but himself that he has butchered. And he will witness what I say who was first taken off thus by a brother's hand. For he went away to the haven without a billow, having gained a glory that dies not away; but the other lived a life worse than any death, groaning, and trembling, and in his body bearing about the accusation of what he had done. Let us not follow after this then, but that. For he that has ill done him, has not an evil that takes up its constant abode with him, since he is not the parent of it; but as he received it from others, he makes it good by his patient endurance. But he that does ill, has the well of the mischief in himself. Was not Joseph in prison, but the harlot that plotted against him in a fine and splendid house? Which then would you wish to have been? And let me not hear yet of the requital, but examine the things that had taken place by themselves. For in this way you will rate Joseph's prison infinitely above the house with the harlot in it. For if you were to see the souls of them both, you would find the one full of enlargement and boldness, but that of the Egyptian woman in straitness, shame, dejection, confusion, and great despondency. And yet she seemed to conquer; but this was no real victor. Knowing all this then, let us fit ourselves for bearing ills, even that we may be freed from bearing ills, and may attain to the blessings to come. Which that we may all attain to, God grant, by the grace and love toward man, etc.
That evil is not to be returned for evil. In the Epistle of Paul to the Romans: "Rendering to no man evil for evil." Also in the same place: "Not to be overcome of evil, but overcome evil with good." Of this same thing in the Apocalypse: "And He said unto me, Seal not the words of the prophecy of this book; because now the time is at hand. And let those who persist in hurting, hurt: and let him who is filthy, be filthy still: but let the righteous do still more righteousness: and in like manner, let him that is holy do still more holiness. Behold, I come quickly; and my reward is with me, to render to every man according to his deeds."
It will do us much good if we refrain from evil. The person who appears to be overcome by evil for a time in fact may be overcoming evil, just as the Savior overcame evil by not resisting it. Evil works against itself, and when it is overcome it thinks that it has won! Our enemy acts in such a way as to divert us from our purpose, looking for an opportunity to make us sin. Therefore if we are provoked by him and do not reply in kind, we overcome him with good. Therefore we do not resist, in order to serve the good by ignoring the demands of justice for retribution.
After giving the wronged person what he wants, Paul goes on to give him advice of a higher tone, telling him not to be overcome with evil. For he knew that even if the enemy was a brute he would not go on being an enemy once he was fed.… To overcome evil with good is true victory.
The evil man who is overcome by good is set free, not from an exterior, foreign evil but from an interior, personal one, by which he is more grievously and ruinously laid waste than he would be by the inhumanity of any enemy from without.
