Jesus says that tradition keeps man from God’s truth: Matthew 15:6-9 Thus you nullify the word of God for the sake of your tradition. You hypocrites! Isaiah was right when he prophesied about you: “‘These people honor me with their lips, but their hearts are far from me. They worship me in vain; their teachings are but rules taught by men.’”
Mark 7:8-9, 13 You have let go of the commands of God and are holding on to the traditions of men.” And he said to them: “You have a fine way of setting aside the commands of God in order to observe your own traditions! 13 Thus you nullify the word of God by your tradition that you have handed down. And you do many things like that.”
