Perhaps the common Jewish person observed ritual washing prior to eating to make certain that his hands were not defiled. Defiled hands made his food unclean. Whatever the origin or reason for this practice, it was traditional. A good intention becomes an evil practice when it opposes God's purposes. If the person's focus is on personal preference, not on a heart committed to God's purposes, God rejects worship.
Acceptable worship requires more than correct procedure.
