The Jews regard and murmur about only the bodily purification of the law; our Lord wishes to bring in the contrary.
Wherefore it is said, “And when He had called all the people unto Him, He said unto them, Hearken unto Me every one, and understand: there is nothing from without a man, that entering into him can defile him, but the things which come out of a man, those are they which defile a man;” that is, which make him unclean.
The things of Christ have relation to the inner man, but those which are of the law are visible and external, to which, as being bodily, the cross of Christ was shortly to put an end.
