Matthew 19:17

Why askest thou me concerning good? [4] In the ordinary Greek copies, why dost thou call me good? (Witham) --- One is good, &c. God alone, by his own nature, is essentially, absolutely, and unchangeably good; at the same time, he is the source of all created goodness, as all goodness is a mere emanation from his. The person here addressing our Saviour, appears not to have believed that Christ was God: wherefore our Saviour, to rectify his misconception, tells him that God alone is good, insinuating thereby, that he should believe him to be God, or cease to address him by the title of good. (Tirinus) --- The sense is, that only God is good necessarily, and by his own nature. The Arians bring this place to shew, that Christ is not truly and properly God: but by this way of speaking, Christ does not deny that he is good, even by his nature, and consequently God; but seems to speak in this manner, to make the man know who he was. (Witham)
