MATT. XXV. 31--41. "When the Son of Man shall come in the glory of His Father, and all the holy angels with Him, then shall He sit," says He, "upon the throne of His glory, and He shall divide the sheep from the kids;"[and the one He will accept, because they fed Him, when an hungered, and gave Him drink when thirsty, and took Him in when a stranger, and clothed Him when naked, and visited Him when sick, and came to see Him when in prison: and He will give the kingdom to them. But the others, accusing them for the opposite things, He will send into the eternal fire, prepared for the devil and his angels.]
Unto this most delightful portion of Scripture, which we do not cease continually revolving, let us now listen with all earnestness and compunction, this wherewith His discourse ended, even as the last thing, reasonably; for great indeed was His regard for philanthropy and mercy. Wherefore in what precedes He had discoursed concerning this in a different way; and here now in some respects more clearly, and more earnestly, not setting forth two nor three nor five persons, but the whole world; although most assuredly the former places, which speak of two persons, meant not two persons, but two portions of mankind, one of them that disobey, the other of the obedient. But here He handles the word more fearfully, and with fuller light. Wherefore neither does He say, "The kingdom is likened," any more, but openly shows Himself, saying, "When the Son of Man shall come in His glory." For now is He come in dishonor, now in affronts and reproaches; but then shall He sit upon the throne of His glory.
And continually does He make mention of glory. For since the cross was near, a thing that seemed to be matter of reproach, for this cause He raises up the hearer; and brings before his sight the judgment seat, and sets round him all the world.
And not in this way only does He make His discourse awful, but also by showing the Heavens opened. For all the angels will be present with Him, He says, themselves also to bear witness, in how many things they had ministered, when sent by the Lord for the salvation of men.
And everything will help to render that day fearful. Then, "shall be gathered together," He says, "all nations," that is, the whole race of men. "And He shall separate them one from another, as the shepherd his sheep." For now they are not separated, but all mingled together, but the division then shall be made with all exactness. And for a while it is by their place that He divides them, and makes them manifest; afterwards by the names He indicates the dispositions of each, calling the one kids,the other sheep, that He might indicate the unfruitfulness of the one, for no fruit will come from kids; and the great profit from the other, for indeed from sheep great is the profit, as well from the milk, as from the wool, and from the young, of all which things the kid is destitute.
But while the brutes have from nature their unfruitfulness, and fruitfulness, these have it from choice, wherefore some are punished, and the others crowned. And He does not punish them, until He has pleaded with them; wherefore also, when He has put them in their place, He mentions the charges against them. And they speak with meekness, but they have no advantage from it now; and very reasonably, because they passed by a work so much to be desired. For indeed the prophets are everywhere saying this, “I will have mercy and not sacrifice,” and the lawgiver by all means urged them to this, both by words, and by works; and nature herself taught it.
But mark them, how they are destitute not of one or two things only, but of all. For not only did they fail to feed the hungry, or clothe the naked; but not even did they visit the sick, which was an easier thing.
And mark how easy are His injunctions. He said not, “I was in prison, and you set me free; I was sick, and you raised me up again;” but, “you visited me,” and, “you came to me.” And neither in hunger is the thing commanded grievous. For no costly table did He seek, but what is needful only, and His necessary food, and He sought in a suppliant's garb, so that all things were enough to bring punishment on them; the easiness of the request, for it was bread; the pitiable character of Him that requests, for He was poor; the sympathy of nature, for He was a man; the desirableness of the promise, for He promised a kingdom; the fearfulness of the punishment, for He threatened hell. The dignity of the one receiving, for it was God, who was receiving by the poor; the surpassing nature of the honor, that He vouchsafed to condescend so far; His just claim for what they bestowed, for of His own was He receiving. But against all these things covetousness once for all blinded them that were seized by it; and this though so great a threat was set against it.
For further back also He says, that they who receive not such as these shall suffer more grievous things than Sodom; and here He says, “Inasmuch as you did it not unto one of the least of these my brethren, you did it not unto me.” What sayest Thou? They are Your brethren; and how dost Thou call them least. Why, for this reason they are brethren, because they are lowly, because they are poor, because they are outcast. For such does He most invite to brotherhood, the unknown, the contemptible, not meaning by these the monks only, and them that have occupied the mountains, but every believer; though he be a secular person, yet if he be hungry, and famishing, and naked, and a stranger, His will is he should have the benefit of all this care. For baptism renders a man a brother, and the partaking of the divine mysteries.
2. Then, in order that you may see in another way also the justice of the sentence, He first praises them that have done right, and says, “Come, you blessed of my Father, inherit the kingdom prepared for you before the foundation of the world. For I was an hungered, and you gave me meat,” and all that follows. For that they may not say, we had it not, He condemns them by their fellow-servants; like as the virgins by the virgins, and the servant that was drunken and gluttonous by the faithful servant, and him that buried his talent, by them that brought the two, and each one of them that continue in sin, by them that have done right.
And this comparison is sometimes made in the case of an equal, as here, and in the instance of the virgins, sometimes of him that has advantage, as when he said, “The men of Nineveh shall rise up and shall condemn this generation, because they believed at the preaching of Jonas; and, behold, a greater than Jonas is here;” and, “The queen of the south shall condemn this generation, because she came to hear the wisdom of Solomon;” and of an equal again, “They shall be your judges;” and again of one at advantage, “Do you not know, that we shall judge angels, how much more things that pertain to this life?”
And here, however, it is of an equal; for he compares rich with rich, and poor with poor. And not in this way only does He show the sentence justly passed, by their fellow-servants having done what was right when in the same circumstances, but also by their not being obedient so much as in these things in which poverty was no hindrance; as, for instance, in giving drink to the thirsty, in looking upon him that is in bonds, in visiting the sick. And when He had commended them that had done right, He shows how great was originally His bond of love towards them. For, “Come,” says He, “you blessed of my Father, inherit the kingdom prepared for you from the foundation of the world.” To how many good things is this same equivalent, to be blessed, and blessed of the Father? And wherefore were they counted worthy of such great honors? What is the cause? “I was an hungered, and you gave me meat; I was thirsty, and you gave me drink;” and what follows.
