Origen
Catena Aurea · Matthäusevangelium 25
When the Son of man shall come in his glory, and all the holy angels with him, then shall he sit upon the throne of his glory: And before him shall be gathered all nations: and he shall separate them one from another, as a shepherd divideth his sheep from the goats: And he shall set the sheep on his right hand, but the goats on the left. Then shall the King say unto them on his right hand, Come, ye blessed of my Father, inherit the kingdom prepared for you from the foundation of the world: For I was an hungred, and ye gave me meat: I was thirsty, and ye gave me drink: I was a stranger, and ye took me in: Naked, and ye clothed me: I was sick, and ye visited me: I was in prison, and ye came unto me. Then shall the righteous answer him, saying, Lord, when saw we thee an hungred, and fed thee? or thirsty, and gave thee drink? When saw we thee a stranger, and took thee in? or naked, and clothed thee? Or when saw we thee sick, or in prison, and came unto thee And the King shall answer and say unto them, Verily I say unto you, Inasmuch as ye have done it unto one of the least of these my brethren, ye have done it unto me. Then shall he say also unto them on the left hand, Depart from me, ye cursed, into everlasting fire, prepared for the devil and his angels: For I was an hungred, and ye gave me no meat: I was thirsty, and ye gave me no drink: I was a stranger, and ye took me not in: naked, and ye clothed me not: sick, and in prison, and ye visited me not. Then shall they also answer him, saying, Lord, when saw we thee an hungred, or athirst, or a stranger, or naked, or sick, or in prison, and did not minister unto thee? Then shall he answer them, saying, Verily I say unto you, Inasmuch as ye did it not to one of the least of these, ye did it not to me.
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 shew 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 shewn to the more holy is more acceptable to God than one shewn to the less holy; and the sin of overlooking the less holy is less than of overlooking the more holy.
