24 Whensoever I take my journey into Spain, I will come to you: for I trust to see you in my journey, and to be brought on my way thitherward by you, if first I be somewhat filled with your company.
[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 253] Origen of Alexandria on Romans 15:24
This must not be understood to mean that Paul had so little love for the Romans that he was only going to drop in on them briefly while passing through on his way elsewhere. Look what he says [in the next few verses] and you will see that this cannot be right.

[AD 386] Cyril of Jerusalem on Romans 15:24
Paul instructed imperial Rome and extended the zeal of his preaching even to Spain, sustaining countless conflicts and performing signs and wonders.

[AD 407] John Chrysostom on Romans 15:24
For that he might not seem to be holding them very cheap, by saying, Since I have not anything to do, therefore I am coming to you, he again touches on the point of love by saying, "I have a great desire, these many years, to come unto you." For the reason why I desire to come, is not because I am disengaged, but that I may give birth to that desire wherewith I am travailing so long. Then that this again should not puff them up, consider how he lowers them by saying, "Whenever I take my journey into Spain, I trust to see you in my journey." For this was why he stated this, that they should not be high-minded. For what he wants is to show his love, and at the same time to prevent them from being dainty. And so he places this close on the other, and uses things confirmative of either alternately. For this reason again that they might not say, Do you make us a by-object of your journey? He adds, and to be brought on my way thitherward by you: that is, that you may be my witnesses that it is not through any slight of you, but by force of necessity, that I run by you. But as this is still distressing, he heals it over more carefully, by saying, "If I be first somewhat filled with your company." For by his saying, "in my journey," he shows that he did not covet their good opinion. But by saying "be filled," that he was eager for their love, and not only was eager for it, but exceedingly so; and this is why he does not say "be filled," but be "somewhat" so. That is, no length of time can fill me or create in me a satiety of your company. See how he shows his love, when even though in haste he does not rise up until he be filled. And this is a sign of his great affectionateness, that he uses his words in so warm a way. For he does not say even I will see, but "shall be filled," imitating thus the language of parents. And at the beginning he said, "that I might have some fruit." [Romans 1:13] But here that I may be "filled." And both these are like a person who is drawing others to him. For the one was a very great commendation of them, if they were likely to yield him fruit from their obedience; and the other, a genuine proof of his own friendship. And in writing to the Corinthians he thus says, "That ye may bring me on my journey wherever I go" [1 Corinthians 16:6], so in all ways exhibiting an unrivalled love to his disciples. And so at the beginning of all his Epistles it is with this he starts, and at the end in this he concludes again. For as an indulgent father does an only and true born son, so did he love all the faithful. Whence it was that he said, "Who is weak, and I am not weak? Who is offended, and I burn not?" [2 Corinthians 11:29]

For before everything else this is what the teacher ought to have. Wherefore also to Peter Christ says, "If you love Me, feed My sheep." [John 21:16] For he who loves Christ loves also His flock. And Moses too did He then set over the people of the Jews, when he had shown a kindly feeling towards them. And David in this way came to be king, having been first seen to be affectionately-minded towards them; so much indeed, though yet young, did he grieve for the people, as to risk his life for them, when he killed that barbarian. But if he said, "What shall be done to the man that kills this Philistine?" [1 Samuel 19:5; ib. 17:26] he said it not in order to demand a reward, but out of a wish to have confidence placed in himself, and to have the battle with him delivered to his charge. And therefore, when he came to the king after the victory, he said nothing of these things. And Samuel too was very affectionate; whence it was that he said, "But God forbid that I should sin in ceasing to pray unto the Lord for you." [1 Samuel 12:23] In like way Paul also, or rather not in like way, but even in a far greater degree, burned towards all his subjects (τὥν ἀρχομένων). Wherefore he made his disciples of such affection towards himself, that he said, "If were possible, you would have pulled out your eyes and given them to me." [Galatians 4:15] On this ground too it is, that God charges the teachers of the Jews above all things with this, saying, "Oh shepherds of Israel, do shepherds feed themselves? Do they not feed the flock?" [Ezekiel 34:2-3] But they did the reverse. For he says, "You eat the milk, and clothe you with the wool, and you kill them that are fed, but you feed not the flock." And Christ, in bringing out the rule for the fittest Pastor, said, "The good shepherd lays down his life for his sheep." [John 10:11] This David did also, both on sundry other occasions, and also when that fearful wrath from above came down upon the whole people. For while all were being slain he said, "I the shepherd have sinned, I the shepherd have done amiss, and these the flock what have they done?" [2 Samuel 24:17] And so in the choice of those punishments also, he chose not famine, nor flight before enemies, but the pestilence sent by God, whereby he hoped to place all the others in safety, but that he should himself in preference to all the rest be carried off. But since this was not so, he bewails, and says, "On me be Your Hand:" or if this be not enough, "on my father's house" also. "For I," he says, "the shepherd have sinned." As though he had said, that if they also sinned, I was the person who should suffer the vengeance, as I corrected them not. But since the sin is mine also, it is I who deserve to suffer the vengeance. For wishing to increase the crime he used the name of "Shepherd." Thus then he stayed the wrath, thus he got the sentence revoked! So great is the power of confession. "For the righteous is his own accuser first." So great is the concern and sympathy of a good Pastor. For his bowels were writhed at their falling, as when one's own children are killed. And on this ground he begged that the wrath might come upon himself. And in the beginning of the slaughter he would have done this, unless he had seen it advancing and expected that it would come to himself. When therefore he saw that this did not happen, but that the calamity was raging among them, he no longer forebore, but was touched more than for Amnon his first-born. For then he did not ask for death, but now he begs to fall in preference to the others. Such ought a ruler to be and to grieve rather at the calamities of others than his own. Some such thing he suffered in his son's case likewise, that you might see that he did not love his son more than his subjects, and yet the youth was unchaste, and an ill-user of his father (πατραλοίας), and still he said, "Would that I might have died for you!" [2 Samuel 18:33] What do you say, thou blessed one, you meek of all men? Your son was set upon killing you, and compassed you about with ills unnumbered. And when he had been removed, and the trophy was raised, do you then pray to be slain? Yea, he says, for it is not for me that the army has been victorious, but I am warred against more violently than before, and my bowels are now more torn than before. These however were all thoughtful for those committed to their charge, but the blessed Abraham concerned himself much even for those that were not entrusted to him, and so much so as even to throw himself among alarming dangers. For when he did what he did, not for his nephew only, but for the people of Sodom also, he did not leave driving those Persians before him until he had set them all free: and yet he might have departed after he had taken him, yet he did not choose it. For he had the like concern for all, and this he showed likewise by his subsequent conduct. When then it was not a host of barbarians that was on the point of laying siege to them, but the wrath of God that was plucking their cities up from the foundations, and it was no longer the time for arms, and battle, and array, but for supplication; so great was the zeal he showed for them, as, if he himself had been on the point of perishing. For this reason he comes once, twice, thrice, aye and many times to God, and finds a refuge (i.e. an excuse) in his nature by saying, "I am dust and ashes" [Genesis 18:27]: and since he saw that they were traitors to themselves, he begs that they may be saved for others. Wherefore also God said, "I will hide not from Abraham My servant that thing which I am about to do" [Genesis 18:17], that we might learn how loving to man the righteous is. And he would not have left off beseeching, unless God had left off first [so he takes Genesis 18:33]. And he seems indeed to be praying for the just, but is doing the whole for them. For the souls of the Saints are very gentle and, loving unto man, both in regard to their own, and to strangers. And even to the unreasoning creatures they extend their gentleness. Wherefore also a certain wise man said, "The righteous pities the souls of his cattle." But if he does those of cattle, how much more those of men. But since I have mentioned cattle, let us just consider the shepherds of the sheep who are in the Cappadocian land, and what they suffer in kind and degree in their guardianship of unreasoning creatures. They often stay for three days together buried down under the snows. And those in Libya are said to undergo no less hardships than these, ranging about for whole months through that wilderness, dreary as it is, and filled with the direst wild beasts (θηρία may include serpents). Now if for unreasonable things there be so much zeal, what defense are we to set up, who are entrusted with reasonable souls, and yet slumber on in this deep sleep? For is it right to be at rest, and in quiet, and not to be running about everywhere, and giving one's self up to endless deaths in behalf of these sheep? Or know ye not the dignity of this flock? Was it not for this that your Master took endless pains, and afterwards poured forth His blood? And do you seek for rest? Now what can be worse than these Shepherds? Do you not perceive, that there stand round about these sheep wolves much more fierce and savage than those of this world? Do you not think with yourself, what a soul he ought to have who is to take in hand this office? Now men that lead the populace, if they have but common matters to deliberate on, add days to nights in watching. And we that are struggling in heaven's behalf sleep even in the daytime. And who is now to deliver us from the punishment for these things? For if the body were to be cut in pieces, if to undergo ten thousand deaths, ought one not to run to it as to a feast? And let not the shepherds only, but the sheep also hear this; that they may make the shepherds the more active minded, that they may the more encourage their good-will: I do not mean by anything else but by yielding all compliance and obedience. Thus Paul also bade them, saying, "Obey them which have the rule over you, and submit yourselves: for they watch for your souls as they that must give account." [Hebrews 13:17] And when he says, "watch," he means thousands of labors, cares and dangers. For the good Shepherd, who is such as Christ wishes for, is contending, before countless witnesses. For He died once for him; but this man ten thousand times for the flock, if, that is, he be such a shepherd as he ought to be; for such an one can die every day. [See on Romans 8:36] And therefore do ye, as being acquainted with what the labor is, coöperate with them, with prayers, with zeal, with readiness, with affection, that both we may have to boast of you, and you of us. For on this ground He entrusted this to the chief of the Apostles, who also loved Him more than the rest; after first asking him if He was loved by him, that you may learn that this before other things, is held as a proof of love to Him. For this requires a vigorous soul. This I have said of the best shepherds; not of myself and those of our days, but of any one that may be such as Paul was, such as Peter, such as Moses. These then let us imitate, both the rulers of us and the ruled. For the ruled may be in the place of a shepherd to his family, to his friends, to his servants, to his wife, to his children: and if we so order our affairs we shall attain to all manner of good things. Which God grant that we may all attain unto, by the grace and love toward man, etc.

[AD 407] John Chrysostom on Romans 15:24
Paul expresses himself in this way in order to keep the Romans from feeling proud. They were not used to being a mere stopover on a journey.

[AD 418] Pelagius on Romans 15:24
It is not certain whether Paul ever got to Spain.… The reason he says that he will enjoy their company “for a little” is that they did not need to come to faith but only to be strengthened in faith. Or it may mean that no amount of time can satisfy love.
