Jesus exposes the danger of man-made traditions

7 ^1-5 And now Jesus was approached by the Pharisees and some of the scribes who had come from Jerusalem. They had noticed that his disciples ate their meals with “common” hands—meaning that they had not gone through a ceremonial washing. (The Pharisees, and indeed all the Jews, will never eat unless they have washed their hands in a particular way, following a traditional rule. And they will not eat anything bought in the market until they have first performed their “sprinkling”. And there are many other things which they consider important, concerned with the washing of cups, jugs and basins.) So the Pharisees and the scribes put this question to Jesus, “Why do your disciples refuse to follow the ancient tradition, and eat their bread with ‘common’ hands?”

^6-8 Jesus replied, “You hypocrites, Isaiah described you beautifully when he wrote—‘This people honours me with their lips, but their heart is far from me. And in vain they worship me, teaching as doctrines the commandments of men’. You are so busy holding on to the traditions of men that you let go the commandment of God!”
