Matthew 25:45

But art thou ashamed to hear that Christ beggeth? Rather be ashamed when thou dost not give to Him begging of thee. For this is shame, this is vengeance and punishment. Since for Him to beg is of His goodness, wherefore we ought even to glory therein; but for thee not to give, is of thy inhumanity. But if thou believe not now, that in passing by a poor man that is a believer, thou passest by Him, thou wilt believe it then, when He will bring thee into the midst and say, "Inasmuch as ye did it not to these, ye did it not to me." But God forbid that we should so learn it, and grant rather that we may believe now, and bring forth fruit, and hear that most blessed voice that bringeth us into the kingdom.

For further back also He saith, that they who receive not such as these shall suffer more grievous things than Sodom; and here He saith, "Inasmuch as ye did it not unto one of the least of these my brethren, ye did it not unto me." What sayest Thou? they are Thy 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 doth 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. So for this cause, while the one are punished justly, the others are crowned by grace. For though they had done ten thousand things, the munificence were of grace, that in return for services so small and cheap, such a heaven, and a kingdom, and so great honor, should be given them.

Wouldest thou do honor to Christ's body? Neglect Him not when naked; do not while here thou honorest Him with silken garments, neglect Him perishing without of cold and nakedness. For He that said, "This is my body," and by His word confirmed the fact, this same said, "Ye saw me an hungered, and fed me not;" and, "Inasmuch as ye did it not to one of the least of these, ye did it not to me." For This indeed needs not coverings, but a pure soul; but that requires much attention. Let us learn therefore to be strict in life, and to honor Christ as He Himself desires. For to Him who is honored that honor is most pleasing, which it is His own will to have, not that which we account best. Since Peter too thought to honor Him by forbidding Him to wash his feet, but his doing so was not an honor, but the contrary. Even so do thou honor Him with this honor, which He ordained, spending thy wealth on poor people. Since God hath no need at all of golden vessels, but of golden souls.

Mark how the righteous dwell upon each word, while the unrighteous answer summarily, and not going through the particular instances; for so it becomes the righteous out of humility to disclaim each individual generous action, when imputed to them publicly; whereas bad men excuse their sins, and endeavour to prove them few and venial. And Christ's answer conveys this. And to the righteous He says, In that ye did it to my brethren, to show the greatness of their good deeds; to the sinners He says only, to one of the least of these, not aggravating their sin. For they are truly His brethren who are perfect; and a deed of mercy shown to the more holy is more acceptable to God than one shown to the less holy; and the sin of overlooking the less holy is less than of overlooking the more holy.
