Jesus as a Philosopher of Kindness

We're so used to thinking of Jesus as a divinity whom we accept or reject on the basis of faith that we're apt to miss a far more relevant detail, that he was an extremely acute philosopher whose rules on human conduct maintain a deep and ongoing applicability. One of the most salient of his lessons comes in chapter 8 of the Gospel of Saint John. Jesus has recently come down from Galilee to Jerusalem when some Pharisees, members of a sect focused on precise adherence to Jewish tradition and law, present him with a married woman whom they have caught having sex with someone other than her husband. Teacher, they ask him. This woman was caught in the very act of committing adultery. In our law, Moses commanded that such a woman must be stoned to death. Now, what do you say? Jesus is being edged into a trap. Will he say that it's completely fine to have an affair? Or will the mild-mannered preacher of love and forgiveness turn out to be just as strict about legal matters as the Jewish authorities he liked to criticise? Jesus makes a deft move. He doesn't categorically deny the mob the right to stone the woman to death, but he adds one apparently small but in practice epochal caveat to this right. They can kill and destroy her to their heart's content if they can be absolutely sure that they have first satisfied one crucial criteria, that they have never done anything wrong themselves. Importantly, by this, Jesus doesn't mean if they've never slept around outside of their marriage. He means if they've never done anything wrong at all, whatsoever, across any area of their lives. Only absolute moral purity grants us the right to be vicious, high-handed and unsparing towards transgressors. An important principle of ethics is being introduced. We are to be counted as properly innocent not when we are blameless in this or that area, but when we have done nothing wrong whatsoever at any point and in any context. Jesus responds to the Pharisees with what have become immortal words. Let him who is without sin cast the first stone. The mob, understanding the rebuke, put down their projectiles and the terrified woman is spared. The real target of this story is a perennial problem in the human soul, self-righteousness. Self-righteousness is the degenerate outgrowth of something that's otherwise extremely valuable, a desire to be in the right. The problem is that being in the right in some areas has a fateful tendency to lead us to see ourselves as morally blameless across our entire lives and therefore encourages a particular mean-spiritedness and inhumanity towards those who transgress in situations where we have been good. Jesus' point is that the surest way to be kind is not to take pride in never having done a particular species of wrong. It lies in seeing that inevitably we too have been foolish and cruel at other moments and in using that knowledge to foster compassion towards those whom it lies in our powers to stone. A world in which we keep our own wrongs firmly in mind becomes paradoxically a properly virtuous and humane place.
