15:1-9 Additions to God's laws reflect upon his wisdom, as if he had left out something which was needed, and which man could supply; in one way or other they always lead men to disobey God. How thankful ought we to be for the written word of God! Never let us think that the religion of the Bible can be improved by any human addition, either in doctrine or practice. Our blessed Lord spoke of their traditions as inventions of their own, and pointed out one instance in which this was very clear, that of their transgressing the fifth commandment. When a parent's wants called for assistance, they pleaded, that they had devoted to the temple all they could spare, even though they did not part with it, and therefore their parents must expect nothing from them. This was making the command of God of no effect. The doom of hypocrites is put in a little compass; In vain do they worship me. It will neither please God, nor profit themselves; they trust in vanity, and vanity will be their recompence.
6. And honour not his father or his mother, he shall be free—that is, It is true, father—mother—that by giving to thee this, which I now present, thou mightest be profited by me; but I have gifted it to pious uses, and therefore, at whatever cost to thee, I am not now at liberty to alienate any portion of it. "And," it is added in Mark (Mr 7:12), "ye suffer him no more to do aught for his father or his mother." To dedicate property to God is indeed lawful and laudable, but not at the expense of filial duty.
Thus have ye made the commandment of God of none effect—cancelled or nullified it "by your tradition."
