the heart ... and not trivial ceremonies
See, for example, Matthew 23:25-28: "Woe unto you, scribes and
Pharisees, hypocrites! for ye make clean the outside of the cup
and of the platter, but within they are full of extortion and
excess. Thou blind Pharisee, cleanse first that which is within
the cup and platter, that the outside of them may be clean also.
Woe unto you, scribes and Pharisees, hypocrites! for ye are like
unto whited sepulchres, which indeed appear beautiful outward,
but are within full of dead men's bones, and of all uncleanness.
Even so ye also outwardly appear righteous unto men, but within
ye are full of hypocrisy and iniquity."
