Jerome
Catena Aurea · Lukasevangelium 18
And a certain ruler asked him, saying, Good Master, what shall I do to inherit eternal life? And Jesus said unto him, Why callest thou me good? none is good, save one, that is, God. Thou knowest the commandments, Do not commit adultery, Do not kill, Do not steal, Do not bear false witness, Honour thy father and thy mother. And he said, All these have I kept from my youth up. Now when Jesus heard these things, he said unto him, Yet lackest thou one thing: sell all that thou hast, and distribute unto the poor, and thou shalt have treasure in heaven: and come, follow me. And when he heard this, he was very sorrowful: for he was very rich. It follows, And he said, All these things have I kept from my youth up.
(in Matt. 19:19.) The young man speaks false, for if he had fulfilled that which was afterwards placed among the commandments, Thou shalt love thy neighbour as thyself, how was it that when he heard, Go and sell all that thou hast, and give to the poor, he went away sorrowful?
