Customs, traditional ways of doing things, are part and parcel of every society, including every religious community. They can be extremely useful, but over time can become pointless. In today’s first reading Moses commands the people to follow their God-given “laws and customs.” And in the Gospel the Pharisees and scribes complain to Jesus that His disciples are eating with unwashed hands, and so are not complying with the Law. They mean that the disciples are ignoring some of the prescriptions that the scribes and Pharisees had added to the Law over the centuries. These regulations were not concerned with health and safety but with ritual purity. Jesus is not suggesting that matters of ritual purity are of no value, but He does insist that there are other things of greater importance. With a quotation from the Prophet Isaiah, He claims that the Pharisees are hypocrites: they are actors, showmen, who offer lip service to the Lord while in fact their hearts are far from Him; their service is worthless. He explains that they should look, not to what goes into the stomach, but what emerges from the heart. It is the human heart that is the source of of uncleanness, of “evil intentions.”
Today’s readings prompt us to examine our attitude towards our own religious customs and practices. We too can become rigid and narrow; we can behave like the Pharisees of old. We can loath to accept any changes in what we’ve been used; even changes that have been approved by the Church, changes made because circumstances have changed or because former practices have been replaced by more helpful ones. Jesus ends the controversy in today’s Gospel by insisting that the heart is the source of “evil things;” but, by implication, it is also the source of good things. Jesus wants a heart that is humble, a heart that knows its own limitations, a heart that is ready to accept change when change is called for, a heart that is in fact like unto His own; He calls to be like Him, “gentle and humble in heart.”
