"And he saith unto them, Are ye so without understanding also? Do ye not perceive, that whatsoever thing from without entereth into the man, it cannot defile him;"

mark 7.18

Christ seems to have a whole new vision of the purity laws, yet it's the same vision Yahweh had. Christ isn't making new standards, He's interpreting the old standards for all of life. He's forcing israel into circumcising their hearts, and they are kicking against His goads.
