Why callest thou me good? - Why do you give to me a title that belongs only to God? You suppose me to be only a man, yet you give me an appellation that belongs only to God.
It is improper to use titles in this manner. As you Jews use them they are unmeaning; and though the title may apply to me, yet, you did not intend to use it in the sense in which it is proper, as denoting infinite perfection or divinity; but you intended to use it as a complimentary or a flattering title, applied to me as if I were a mere man - a title which belongs only to God. The intentions, the habit of using mere titles, and applying as a compliment terms belonging only to God, is wrong. Christ did not intend here to disclaim divinity, or to say anything about his own character, but simply to reprove the intention and habit of the young man - a most severe reproof of a foolish habit of compliment and flattery, and seeking pompous titles.
