But when the Son of Man comes in his glory, and all the holy angels with him, then he will sit on the throne of his glory. Before him all the nations will be gathered, and he will separate them one from another, as a shepherd separates the sheep from the goats. He will set the sheep on his right hand, but the goats on the left.
Then the King will tell those on his right hand, "Come, 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 to eat. I was thirsty, and you gave me drink. I was a stranger, and you took me in. I was naked, and you clothed me. I was sick, and you visited me. I was in prison, and you came to me."
Then the righteous will answer him, saying, "Lord, when did we see you hungry, and feed you; or thirsty, and give you a drink? When did we see you as a stranger, and take you in; or naked, and clothe you? When did we see you sick, or in prison, and come to you?" The King will answer them, "Most certainly I tell you, inasmuch as you did it to one of the least of these my brothers, you did it to me."
Then he will say also to those on the left hand, "Depart from me, you cursed, into the eternal fire which is prepared for the devil and his angels; for I was hungry, and you didn't give me food to eat; I was thirsty, and you gave me no drink; I was a stranger, and you didn't take me in; naked, and you didn't clothe me; sick, and in prison, and you didn't visit me."
Then they will also answer, saying, "Lord, when did we see you hungry, or thirsty, or a stranger, or naked, or sick, or in prison, and didn't help you?" Then he will answer them, saying, "Most certainly I tell you, in as much as you didn't do it to one of the least of these, you didn't do it to me." These will go away into eternal punishment, but the righteous into eternal life."
From Matthew 25:31–46:
This seems a bit harsh on goats... but in line with their common (western) association with Satan. Christianity is a dualist faith, meaning that everything is separated into black or white, evil or good, as is the case here. My own beliefs are, like Hinduism, monistic, whereby black and white cannot exist without each other, and are both aspects of one reality (cosmic energy). Consequently I do not believe in the allocation of souls, upon death, to either heaven or hell: rather, everything is based on the law of karma, and we are all forced, one way or another, to atone fully for past sins, in future incarnations. It is not that sheep are good and goats are bad. Both have a mix of virtue and viciousness, and each one has a valuable role to play. For me, the goats are as good as the sheep, only different in nature: the sheep do what they are told, a quality greatly valued by religious leaders, and the goats stubbornly go their own way, and so are castigated. Similarly, the left hand is no worse than the right, only different: both are required for balance and harmony. Darkness is simply the absence of light. In ultimate reality, there is only light (divine consciousness), and all of creation is imbued with light to a greater or lesser extent. The sheep find enlightenment through devotion (following a leader), while the goats find it independently through knowledge of the self (inner reflection). I am a goat.
