Matthew 15:1-20

This chapter is an expression of the conflict between human tradition and the perfect Law. Jesus is direct and forceful with the Pharisees, but then he quotes Isaiah who is no kiss on the cheek either. By the end even the disciples have to be instructed. What you eat, and your hands (clean or dirty) do not defile you. (It is the heart that makes the real difference) It is what comes out of your mouth that shows if your Heart/Mind/Soul is defiled. In saying this Jesus does not contradict the necessity of cooking food or being clean in its preparation. So cooking shows on television can still be works of righteousness... ('course that depends on the spiritual condition of those folks)
