"Then shall the king say to them that shall be on his right hand: 'Come, ye blessed of my Father, possess you the kingdom prepared for you from the foundation of the world. For I was hungry, and you gave me to eat: I was thirsty, and you gave me to drink: I was a stranger, and you took me in: Naked, and you covered me: sick, and you visited me: I was in prison, and you came to me.' Then shall the just answer him, saying: 'Lord, when did we see thee hungry and fed thee: thirsty and gave thee drink? Or when did we see thee a stranger and took thee in? Or naked and covered thee? Or when did we see thee sick or in prison and came to thee?' And the king answering shall say to them: 'Amen I say to you, as long as you did it to one of these my least brethren, you did it to me.'
Then he shall say to them also that shall be on his left hand: 'Depart from me, you cursed, into everlasting fire, which was prepared for the devil and his angels. For I was hungry and you gave me not to eat: I was thirsty and you gave me not to drink. I was a stranger and you took me not in: naked and you covered me not: sick and in prison and you did not visit me.' Then they also shall answer him, saying: 'Lord, when did we see thee hungry or thirsty or a stranger or naked or sick or in prison and did not minister to thee?' Then he shall answer them, saying: 'Amen: I say to you, as long as you did it not to one of these least, neither did you do it to me.' And these shall go into everlasting punishment: but the just, into life everlasting." (Matt. 25:34-46)
FAITH ALONE CANNOT SAVE: In the parable of the virgins our Lord taught us plainly that the oil of good works is necessary in addition to the lamp of faith; and He related the parable of the talents for the sole purpose of showing us that he only can be saved who uses the gifts and graces given to him by God, for the practice of works pleasing to God. Now, in the account we have read today, our Lord tells us that at the judgment those will be condemned who do not practice works of mercy, and that good works alone can claim the eternal reward of heaven. It is therefore our Lord's distinct doctrine, that good works are necessary for salvation, and it is almost inconceivable that the comfortable idea that faith alone will save us, should ever have been proclaimed to be the doctrine of Christ!
