Titus of Bostra
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.
When he says then, Good Master, what shall I do to inherit eternal life? it is the same as if he says, Thou art good; vouchsafe me then an answer to my question. I am learned in the Old Testament, but I see in Thee something far more excellent. For Thou makest no earthly promises, but preachest the kingdom of heaven. Tell me then, what shall I do to inherit eternal life? The Saviour then considering his meaning, because faith is the way to good works, passes over the question he asked, and leads him to the knowledge of faith; as if a man was to ask a physician, “What shall I eat?” and he was to shew him what ought to go before his food. And then He sends him to His Father, saying, Why callest thou me good? not that He was not good, for He was the good branch from the good tree, or the good Son of the good Father.
