Matthew 19:18

18.Thou shalt not murder It is surprising that, though Christ intended to show that we are bound to obey the whole law, he should mention the second table only; but he did so, because from the duties of charity the disposition of every man is better ascertained. Piety towards God holds, no doubt, a higher rank; (623) but as the observation of the first table is often feigned by hypocrites, the second table is better adapted for making a scrutiny. (624) Let us know, therefore, that Christ selected those commandments in which is contained a proof of true righteousness; but by a synecdoche he takes a part for the whole. As to the circumstance of his placing that commandment last which speaks of honoring parents, it is of no consequence, for he paid no attention to the regular order. Yet it is worthy of notice, that this commandment is declared to belong to the second table, that no one may be led astray by the error of Josephus, who thought that it belonged to the first table. (625) What is added at the end, Thou shalt love thy neighbor, contains nothing different from the former commandments, but is, general explanation of them all.

The young man saith to him. The law must have been dead to him, when he vainly imagined that he was so righteous; for if he had not flattered himself through hypocrisy, it was an excellent advice to him to learn humility, to contemplate his spots and blemishes in the mirror of the law. But, intoxicated with foolish confidence, he fearlessly boasts that he has discharged his duty properly from his childhood. Paul acknowledges that the same thing happened to himself, that, so long as the power of the law was unknown to him, he believed that he was alive; but that, after he knew what the law could do, a deadly wound was inflicted on him, (Romans 7:9.) So the reply of Christ, which follows, was suited to the man’s disposition. And yet Christ does not demand any thing beyond the commandments of the law, but, as the bare recital had not affected him, Christ employed other words for detecting the hidden disease of avarice.

I confess that we are nowhere commanded in the law to sell all; but as the design of the law is, to bring men to self-denial, and as it expressly condemns covetousness, we see that Christ had no other object in view than to correct the false conviction of the young man. (626) for if he had known himself thoroughly, as soon as he heard the mention of the law, he would have acknowledged that he was liable to the judgment of God; but now, when the bare words of the law do not sufficiently convince him of his guilt, the inward meaning is expressed by other words. If Christ now demanded any thing beyond the commandments of the law, he would be at variance with himself. He just now taught that perfect righteousness is comprehended in the commandments of the law: how then will it agree with this to charge the law with deficiency? Besides, the protestation of Moses, (Deuteronomy 30:15,) which I formerly quoted, would be false.
