The Pharisees were seen as extremely scrupulous adherents to God's law but Jesus insisted that" unless your righteousness exceeds the righteousness of the scribes and Pharisees, you will never enter the kingdom of heaven." There is a deeper righteousness than simply avoiding sin or not doing something wrong. Jesus explains, " You have heard it said, you shall not murder." Initially, we readily assume that we have complied with the sixth commandment. But Jesus takes it further, I say to you that if you are angry with your brother or sister, then you have also transgressed this commandment. In this instance, he is speaking of a grudge:the kind that ruins relationships, splits families, and divides congregations.
He then re-defines anger in how we use words to demonize or de-personalize others. When we use labels or categorize people according to race, gender, appearance, or social-economic level we practice a form of murder. They are no longer people made in God's image, they are fools, idiots, or morons.
So how do we keep the 6th commandment? When you approach God and you remember that somebody has something against you. Leave your gift at the altar and be reconciled to that person! we can't say we are sorry to God until we first say we are sorry to others! Making amends is not about blame, it's about obedience to God. For Jesus warns us: Do it quickly, don't let it go on too long. The longer it lasts the harder it is to say I'm Sorry!
