Matthew 15:10-11
And he called the multitude, and said unto them, Hear, and understand: Not that which goeth into the mouth defileth a man; but that which cometh out of the mouth, this defileth a man.
People get caught up into the traditions of man. What matters to God is our actions. If we follow his teachings we will not do anything that defiles us. If we start following the teachings of man about how to say things or what can and cannot do certain days of the week, we defile ourselves before God.
