This narrative agrees in some respects, but not entirely, with the doctrine laid down by Matthew, (Matthew 10:1,) that Christ, in order to correct the superstition of the people, and particularly of the scribes, intentionally disregarded outward ceremonies of human invention, which the Jews were too solicitous to observe. God had prescribed in his Law certain kinds of washings, that by means of them he might train his people usefully to the consideration of true purity. The Jews, not satisfied with this moderate portion had added many other washings, and more especially, that no person should partake of food till he had been washed with the water of purification, as Mark relates more minutely, (Mark 12:3,) and as is also evident from John, (John 2:6.) This fault was accompanied by wicked confidence; for they cared little about the spiritual worship of God, and thought that they had perfectly discharged their duty, when the figure was substituted in the place of God. Christ is fully aware that his neglect of this ceremony will give offense, but he declines to observe it, in order to show that God sets very little value on outward cleanness, but demands the spiritual righteousness of the heart.
