Even in our day...

 Matthew 15
You cancel the word of God for the sake of your own tradition. 7 You hypocrites! Isaiah was right when he prophesied about you, for he wrote,

8 ‘These people honor me with their lips,
    but their hearts are far from me.
9 Their worship is a farce,
    for they teach man-made ideas as commands from God.’

10 Then Jesus called to the crowd to come and hear. “Listen,” he said, “and try to understand. 11 It’s not what goes into your mouth that defiles you; you are defiled by the words that come out of your mouth.”

12 Then the disciples came to him and asked, “Do you realize you offended the Pharisees by what you just said?”

13 Jesus replied, “Every plant not planted by my heavenly Father will be uprooted, 14 so ignore them. They are blind guides leading the blind, and if one blind person guides another, they will both fall into a ditch.”
