And honour not his father or his mother, he shall be free. Thus have ye made the commandment of God of none effect by your tradition.

They accused Christ's disciples of breaking tradition by eating with unwashed hands, a decent custom the Pharisees had turned into a religious duty. That this was the worst charge they could bring shows how inoffensively His disciples lived.

Commenting on Matthew 15:1-9
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 honour not his father or his mother, [he shall be free]. Thus have ye made the commandment of God of none effect by your tradition. (d) As much as you could, you destroyed the power and authority of the commandment: for otherwise the commandments of God stand fast in the Church of God, in spite of the world and Satan.
