THE LORD SAID, “When the Son of Man comes in His glory, and all the angels with Him, then He will sit on the throne of His glory. All the nations will be gathered before Him, and He will separate people one from another as a shepherd separates the sheep from the goats. He will place the sheep on His right hand and the goats on the left. Then the King will say to those on His right hand, ‘Come, you that are blessed of My Father, inherit the Kingdom prepared for you from the foundation of the world. For I was hungry and you gave Me food; I was thirsty and you gave Me something to drink; I was a stranger and you welcomed Me. I was naked and you gave Me clothing; I was sick and you took care of Me; I was in prison and you visited Me.’ Then the righteous will answer Him, saying, ‘Lord, when did we see You hungry and feed You; or thirsty and gave You something to drink? And when did we see You a stranger and welcome You; or naked and gave You clothing? And when did we see You sick or in prison and visited You?’ And the King will answer them, ‘Truly I tell you, just as you did it to one of the least of these My brothers, you did it to Me.’ Then the King will say to those on His left hand, ‘Depart from Me, you that are accursed, into the eternal fire prepared for the devil and his angels. For I was hungry and you gave Me no food; I was thirsty and you gave Me nothing to drink; I was a stranger and you did not welcome Me; naked and you did not give Me clothing; sick and in prison and you did not visit Me.’ Then they also will answer Him, ‘Lord, when did we see You hungry or thirsty or a stranger or naked or sick or in prison, and did not take care of You?’ Then He will answer them, ‘Truly I tell you, just as you did not do it to one of the least of these, you did not do it to Me.’ And these will go away into eternal punishment, but the righteous will go into eternal life.”
A comment from the Holy Fathers on the King separating the people into two groups:
So then, people on earth are intermingled, and not only intermingled in that the righteous live side by side with the wicked, but they are also indistinguishable. Between the righteous and the wicked there is no apparent difference. Even as in wintertime you cannot tell the healthy trees apart from the withered trees but in beautiful springtime you can tell the difference, so too each person according to their faith and their works will be exposed. The wicked will not have any leaves or show any fruit, but the righteous will be clothed with the leaves of eternal life and adorned with the fruit of glory. In this way they will be separated by the heavenly shepherd and Lord. The earthly shepherd separates animals by their type of body, whereas Christ separates people by their type of soul. The sheep signify righteous people by reason of their gentleness, because they harm no one, and by reason of their patience, because when they are harmed by others, they bear it without resistance. He refers to sinners as goats, however, because these vices characterize goats: capriciousness toward other animals, pride, and belligerence.
