Be perfect?

Many people get a buzz out of hate and find solidarity (communion) in hating common enemies. It can shape national and ethnic identities, as it can denominations, and ideological and theological movements. To live with all people with respect, accepting the need for difficult negotiations and for courageous conflict resolution is demanding. Short-cuts through complexity do violence not only to the truth but also to people."Perfect" is not flawless, unstained purity, but integrity and truth. For the young man, later in 19:21, where Matthew introduces "perfect" again, it means, in a fine play on words, grown-up, mature faith which shows itself in a deep commitment to the poor. The same word means "perfect' and "mature". It is about grown-up faith. It is not about partial or part-time religiosity. There is for Matthew only one way for all - being completely open to love, to receive it and give it. In his own and sometimes controversial way Matthew makes this a theme through every main speech of Jesus and in the end makes it the sole criterion of judgement
