16 Salute one another with an holy kiss. The churches of Christ salute you.
[AD 407] John Chrysostom on Romans 9:22-23:24
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:

[AD 407] John Chrysostom on Romans 16:1-16
I think there are many, even some apparently good commentators, who hurry over this part of the epistle because they think it is superfluous and of little importance. They probably think much the same about the genealogies in the Gospels. Because it is a catalog of names, they think they can get nothing good out of it. People who mine gold are careful even about the smallest fragments, but these commentators ignore even huge bars of gold!

[AD 215] Clement of Alexandria on Romans 16:16
If we are called to the kingdom of God, let us walk worthy of the kingdom, loving God and our neighbor. Love is not proved by a kiss but by kindly feeling. But there are those who do nothing but make the church resound with a kiss, not having love itself inside them. For this very thing, the shameless use of a kiss, which ought to be mystic, occasions foul suspicions and evil reports. The apostle, however, calls the kiss holy.

[AD 220] Tertullian on Romans 16:16
What prayer is complete if it is divorced from the holy kiss?

[AD 220] Tertullian on Romans 16:16
But when is peace more to be concluded with brethren than when, at the time of some religious observance, our prayer ascends with more acceptability; that they may themselves participate in our observance, and thereby be mollified for transacting with their brother touching. their own peace? What prayer is complete if divorced from the "holy kiss? " Whom does peace impede when rendering service to his Lord? What kind of sacrifice is that from which men depart without peace? Whatever our prayer be, it will not be better than the observance of the precept by which we are bidden to conceal our fasts; for now, by abstinence from the kiss, we are known to be fasting.

[AD 253] Origen of Alexandria on Romans 16:16
From this and other statements like it, it appears that it was the custom to greet one another with a kiss after the prayers. The apostle calls this a holy kiss. How could Paul write that all the churches sent greetings, when he was only in one of them at the time? I think we have to understand this to mean that there was one spirit common to Paul and to all the churches, so that he could speak on behalf of them all.

[AD 384] Ambrosiaster on Romans 16:16
Paul asks that all those to whom he has written and whom he names be greeted with a holy kiss, that is, in the peace of Christ, not in the desire of the flesh, because these kisses are spiritual, not physical.By saying “churches of Christ” Paul is saying that there is a church which is not Christ’s. For David called the company of evildoers an assembly of the wicked.

[AD 407] John Chrysostom on Romans 16:16
To cast out of them, by this salutation, all arguing that confused them, and all grounds for little pride; that neither the great might despise the little, nor the little grudge at the greater, but that haughtiness and envy might be more driven away, when this kiss soothed down and levelled every one. And therefore he not only bids them salute in this way, but sends in like manner to them the greeting from the Churches. For "there salute you," he says, not this or that person individually, but all of you in common,

"The Churches of Christ."

You see that they are no small gains that we earn from these addresses, and what treasures we should have passed hastily over, unless in this part of the Epistle also we had examined it with accuracy, such, I mean, as was in our power. So if there be found any man of wisdom and spiritual, he will dive even deeper, and find a greater number of pearls. But since some have often made it a question wherefore it was that in this Epistle he addressed so many, which thing he has not done in any other Epistle, we might say that it is owing to his never having seen the Romans yet, that he does this. And yet one may say, "Well, he had not seen the Colossians either, and yet he did not do anything of the kind." But these were more honorable than others, and had come there from other cities, as to a safer and more royal city. Since then they were living in a foreign country, and they needed much provision for security, and some of them were of his acquaintance, but some too were there who had rendered him many important services, he with reason commends them by letters; for the glory of Paul was then not little, but so great, that even from his sending them letters, those who had the happiness to have an Epistle to them, gained much protection. For men not only reverenced him, but were even afraid of him. Had this not been so, he would not have said, who had been "a succorer of many, and of myself also." [Romans 16:2] And again, "I could wish that myself were accursed." [Romans 9:3] And to Philemon he wrote and said, "as Paul the aged, and a prisoner of Jesus Christ." [Philippians 9] And to the Galatians, "Behold, I Paul say unto you." [Galatians 5:2] And, "You received me even as Jesus Christ." [Galatians 4:14] And writing to the Corinthians he said, "Now some are puffed up, as though I would not come unto you." [1 Corinthians 4:18] And again, "These things I have in a figure transferred to myself and to Apollos, that you might learn in us not to think of men above that which is written." [1 Corinthians 4:6] Now from all these passages it is clear that all had a great opinion of him. Wishing then that they should feel on easy terms, and be in honor, he addressed each of them, setting forth their praise to the best advantage he might. For one he calls beloved, another kinsman, another both, another fellow-prisoner, another fellow-worker, another approved, another elect. And of the women one he addresses by her title, for he does not call her servant of the Church in an undefined way (because if this were so he would have given Tryphena and Persis this name too), but this one as having the office of deaconess, and another as helper and assistant, another as mother, another from the labors she underwent, and some he addresses from the house they belonged to, some by the name of Brethren, some by the appellation of Saints. And some he honors by the mere fact of addressing them, and some by addressing them by name, and some by calling them first-fruits, and some by their precedence in time, but more than all, Priscilla and Aquila. (τοὺς περὶ Πρ. κ. ᾿Α.) For even if all were believers, still all were not alike, but were different in their merits. Wherefore to lead them all to greater emulation, he keeps no man's encomiums concealed. For when they who labor more, do not receive the greater reward also, many become more listless. On this ground even in the kingdom, the honors are not equal, nor among the disciples were all alike, but the three were preëminent above the rest. And among these three again there was a great difference. For this is a very exact method observed by God even to the last. Hence, "one star differs from another star in glory," [1 Corinthians 15:41], it says. And yet all were Apostles and all are to sit on twelve thrones, and all left their goods, and all companied with Him; still it was the three He took. And again, to these very three, He said it was possible (ἐ γχωρεῖν) that some might even be superior. "For to sit," He says, "on My right hand and on My left, is not mine to give, save to those for whom it is prepared." [Mark 10:40] And He sets Peter before them, when He says, "Lovest thou Me more than these?" [John 21:15] And John too was loved even above the rest. For there shall be a strict examination of all, and if you be but little better than your neighbor, if it be even an atom, or anything ever so little, God will not overlook even this. And this even from of old one might see coming out. For even Lot was a righteous man, yet not so, as was Abraham; and Hezekiah again, yet not so as was David: and all the prophets, yet not so as was John.

Where then are they who with all this great exactness in view, yet will not allow that there is a hell? For if all the righteous are not to enjoy the same lot, if they exceed others even a little ("for one star," it says, "differs from another star in glory,") [1 Corinthians 15:41], how are sinners to be in the same lot with the righteous? Such a confusion as this even man would not make, much less God! But if you will, I will show you that even in the case of sinners, arguing from existing facts, there is this distinction, and exact just judgment. Now consider; Adam sinned, and Eve sinned, and both transgressed, yet they were not equally sinful. And therefore neither were they equally punished. For the difference was so great that Paul said, "Adam was not deceived but the woman being deceived was in the transgression." And yet the deceit was one. But still God's searching examination pointed out a difference so great, as that Paul should make this assertion. Again, Cain was punished, but Lamech, who committed a murder after him, did not suffer near so great a punishment. And yet this was a murder, and that was a murder, and that so much the worse, because even by the example he had not become the better. But since the one neither killed his brother after exhortation, nor needed an accuser, nor shrunk from answering when God questioned him, but even without any accuser both pleaded again himself, and condemned himself more severely, he obtained pardon. But the other as having done the opposite was punished. See with what exactness God sifts the facts. For this reason He punished those in the flood in one way, and those in Sodom in another; and the Israelites again, both those in Babylon, and those in Antiochus' time, in different ways: so showing that He keeps a strict account of our doings. And these were slaves for seventy years, and those for four hundred, but others again ate their children, and underwent countless other more grievous calamities, and even in this way were not freed, either they or those that were burnt alive in Sodom. "For it shall be more tolerable," He says, "for the land of Sodom and Gomorrha, than for that city." [Matthew 10:15] For if He has no care for us, either when we sin or when we do aright, perhaps there will be some reason in saying that there is no punishment. But since He is so exceedingly urgent about our not sinning, and adopts so many means to keep us in the right, it is very plain that He punishes the wicked, and also crowns those that do right. But let me beg you to consider the unfairness of the generality. For they find fault with God because He so often long-suffering, overlooks so many that are impious, impure, or violent, without now suffering punishment. Again, if He threaten to punish them in the other world, they are vehement and pressing in their accusations. And yet if this be painful, they ought to accept and admire the other. But alas the folly! The unreasonable and asinine spirit! Alas the sin-loving soul, that gazes after vice! For it is from this that all these opinions have their birth. And so if they who utter these things should be minded to lay hold upon virtue, they will presently find themselves satisfied concerning hell also, and will not doubt. And where (it is said) and in what place is this hell? For some fablers say that it is in the valley of Josaphat, thus drawing that which was said about a certain by-gone war, to apply to hell. But the Scripture does not say this. But in what place, pray, will it be? Somewhere as I think at least quite out of the pale of this world. For as the prisons and mines are at a great distance from royal residences, so will hell be somewhere out of this world. Seek we not then to know where it is, but how we may escape it. Neither yet because God does not punish all here, therefore disbelieve things to come. For merciful and long-suffering He is: that is why he threatens, and does not cast us into it immediately. For "I desire not," He says, "the death of a sinner." [Ezekiel 18:32] But if there is no death of a sinner, the words are but idle. And I know indeed that there is nothing less pleasant to you than these words. But to me nothing is pleasanter. And would it were possible at our dinner, and our supper, and our baths, and everywhere, to be discoursing about hell. For we should not then feel the pain at the evils in this world, nor the pleasure of its good things. For what would you tell me was an evil? poverty? Disease? captivity? Maiming of the body? Why all these things are sport compared to the punishment there, even should you speak of those who are tormented with famine all their life long; or those who are maimed from their earliest days, and beg, even this is luxury compared to those other evils. Let us then continually employ ourselves with talking about these things. For to remember hell prevents our falling into hell. Do you not hear St. Paul saying, "Who shall suffer everlasting punishment from the face of the Lord?" [2 Thessalonians 1:9] Do you not hear what Nero's character was, whom Paul even calls the Mystery of Antichrist? For "the mystery of iniquity," he says, "already works." [2 Thessalonians 2:7] What then? Is Nero to suffer nothing? Is Antichrist to suffer nothing? Or the Devil nothing? Then he will always be Antichrist, and so the Devil. For from mischief they will not leave off, unless they be punished. "Yea," you say, "but that there is a hell everybody sees. But the unbelievers only are to fall into it." What is the reason, pray? It is because the believers acknowledge their Master. And what is this to the purpose? When their life is impure, they will on this ground be punished more severely than the unbelievers. "For as many as have sinned without law shall also perish without law: but as many as have sinned in the law shall be judged by the law." [Romans 2:12] And, "The servant that knew his master's will, and did it not, shall be beaten with many stripes." [Luke 12:47] But if there is no such thing as giving an account of one's life, and all this is said in a loose way then neither will the Devil have vengeance taken upon him. For he too knows God, and far more than men too, and all the demons know Him, and tremble, and own He is their Judge. If then there is no giving an account of our life, nor of evil deeds, then will they also clean escape. These things are not so, surely they are not! Deceive not yourselves, beloved. For if there is no hell, how are the Apostles to judge the twelve tribes of Israel? How comes Paul to say, "Do you not know that we shall judge Angels? How much more things of this life?" [1 Corinthians 6:3] How came Christ to say, "The men of Nineveh shall arise and condemn this generation" [Matthew 12:41]; and, "It shall be more tolerable for the land of Sodom in the day of judgment?" [Matthew 11:24] Why then make merry with things that are no subjects for merriment? Why deceive yourself and put cheats upon your reason (παραλογίζῃ, om. τὴν ψυχήνσου)? Why fight with the love of God toward man? For it was through this that He prepared it, and threatened, that we might not be cast into it, as having by this fear become better. And thus he that does away with speaking on these subjects does nothing else than thrust us into it, and drive us there by this deceit. Slacken not the hands of them then that labor for virtue, nor make the listlessness of them that sleep greater. For if the many be persuaded that there is no hell, when will they leave off vice? Or when will right be seen? I do not say between sinners and righteous men, but between sinners and sinners? For why is it that one is punished here, and another not punished, though he does the same sins, or even far worse? For if there be no hell, you will having nothing to say in defense of this to those who make it an objection. Wherefore my advice is, that we leave off this trifling, and stop the mouths of those that are gainsayers upon these subjects. For there will be an exact searching into the smallest things, both in the way of sins and in the way of good deeds, and we shall be punished for unchaste looks, and for idle words, and for mere reproachful words, and for drunkenness we shall render an account, as even for a cup of cold water we shall receive a reward, and a sigh only. [Ecclesiastes 12:14] For it says, "Set a mark upon the foreheads of the men that sigh and that cry." [Ezekiel 9:4] How then do you dare to say that He, who with so great exactness will search into our doings, threatened hell in bare words, and lightly? Do not, I beseech you, do not with these vain hopes destroy yourself and those that are persuaded by you! For if you disbelieve our words, make enquiry of Jews and Gentiles, and all heretics. And all of them as with one mouth will answer that a judgment there shall be, and a retribution. And are men not enough? Ask the devils themselves, and you will hear them cry, "Why have you come there to torment us before the time." [Matthew 8:29] And putting all this together persuade your soul not to trifle idly, lest by experience thou come to know there is a hell, but from this you may be sobered, and so able to escape those tortures, and attain to the good things to come; whereof may we all partake by the grace and love towards man, etc.

[AD 407] John Chrysostom on Romans 16:16
By this salutation Paul intended to cast out of them any reason for pride. The great were not to despise the small, nor were the small to envy the great, but pride and envy were to be banished by the kiss, which made everyone equal. Therefore, he not only asks them to greet each other in this way, but he also sends them this greeting from the other churches.

[AD 418] Pelagius on Romans 16:16
Not with a false and treacherous kiss, of the sort with which Judas betrayed the Savior. For in the church the peace is proclaimed first, so that we may show that we are at peace with all who are about to partake of the body of Christ.
