If you wish to read the texts click here: Galatians 5:1-6; Lk 11:37-41
The section beginning in Lk 11:37 and ending in 11:54 is set in the context of a meal. The text of today begins with the notice that a Pharisee invited Jesus for a meal. Jesus sits/reclines at table without washing his hands, and this amazes his host. The Pharisees observed strict rules regarding ritual cleanliness, and generally ate only with those who also maintained ritual purity. By not washing, Jesus scandalizes his host. This amazement allows Jesus to give all those present a lesson on internal and external cleanness.
Jesus’ response to his host who is surprised because Jesus did not first wash, is that God is not concerned with the observance of rituals of purity, but with the purity of the heart. A person’s actions should reflect his or her inner purity.
The best way to remove greed and wickedness from one’s heart is to be generous with what one has. The practice of constant giving, leads one to develop an attitude of detachment.
