Catena Aurea on Luke 18:18–23: Cyril of Alexandria

Now he thought to detect Christ in blaming the law of Moses, while He introduced His own commands. He went then to the Master, and calling Him good, says that he wishes to be taught by Him, for he sought to tempt Him. But He who takes the wise in their craftiness answers him fitly as follows, Why callest thou me good? there is none good, save God alone.
