Catena Aurea on Luke 11:37–44: Augustine of Hippo

For every day before dinner the Pharisees washed themselves with water, as if a daily washing could be a cleansing of the heart. But the Pharisee thought within himself, yet did not give utterance to a word; nevertheless, He heard who perceived the secrets of the heart. Hence it follows, And the Lord said unto him, Now do ye Pharisees make clean the outside of the cup and the platter; but your inward part is full of ravening and wickedness.
