In chapter seven of the Gospel of Mark, we discover what, in the eyes of Jesus, true religion is all about. For the Pharisees the emphasis was on observation of the law, both written and oral. For Jesus, however, what matters is the heart. More external observance without a corresponding movement of the heart does not please God. We are invited to see what is really important for our lives. In the Gospel of Mark the Pharisees are seen as the main opponents of Jesus. They eventually succeed in getting Jesus arrested and executed. Jesus' approach to the law was different than that of the Pharisees. Jesus put the spirit of the law before its external observance. For him, the life of a child of God is much more than a mere external observance of the laws. Jesus wants people to come to a real relationship with God. He challenges us to move from conformity to conversion. The Pharisees believed that anything less than a literal observance of the law would undermine God's people. If they removed Jesus they would be defending God and his law. Jesus challenges us to look not at externals but at our hearts. In the language of the bible the heart is the center of the human person. God's people are invited to 'love God with all their heart' (Dt 6:5). One who rejects God's ways, is said to have a 'heart of stone.' God no longer writes his law on stone tablets, but in the hearts of his people (Jer 31:31-34). Jesus begins his ministry by asking his hearers for a change of heart and a complete turning back to God (Mk 1:15). True religion is not a question of doing things, like praying or going to church. Religion is a matter of the heart. Long before Jesus, the prophets had fought against a formalism in religion that reduced it to lip-service and nice liturgies that did not bring about a change of heart. In the discussion about clean and unclean, Jesus shows us that the home of good and evil is the heart. It is in the heart that each one decides how to relate to God and to others. It is our hearts that we must give to God.
