In the New Testament, the Pharisees are usually presented as enemies and foes of Jesus. Their presentation is rather biased and one-sided, limited to controversial issues. The Gospels usually fail to show what positive in their lives and in harmony with that of a Christian was. In the passage of Mt 23:25-26, Jesus does not so much criticize the Pharisees for respecting the rules of ritual purity in their daily lives, but shows what sin in human life is, not only in the life of a Pharisee, but everyone. Everyone is called to convert, change its attitude, reject hypocrisy and live according to the Gospel principles. Jesus uses the metaphor of a cup and a dish to easily show his listeners that, as in the case of everyday objects, which first they are washed inside, then outside, exactly the same should happen with a man, he should first purify his soul and then show himself good towards others.
