When we believe we are in possession of complete knowledge of God, then it endows our actions with unassailable goodness. Even actions that we condemn when performed by our opponents will appear good and noble to us when we do them. A wonderful illustration of this comes from 1 Kings 18 where we are told that Queen Jezebel, the Baal worshipper, has been “killing off the prophets of the Lord” (18:4). To demonstrate that the Lord, not Baal, is God, the prophet Elijah miraculously ignites a sacrificial fire that humiliates Baal’s prophets. Elijah then “seized them; and Elijah brought down to the Wadi Kishon, and killed them there” (18:40).
I’m not sure we are meant to applaud Elijah’s murderous rampage. I think the biblical text invites us to see the similarities between Elijah and Jezebel, despite their insistence on how different they are from one another. They are both so strongly in the grip of religious fundamentalism that they condemn each other as murderers while celebrating murder as justified by their god. Nothing can dissuade them from their belief in their own goodness, not even the blood of their victims. This is what James Alison is referring to when he says that “our self-identity as ‘good’ is one of our most sacred idols. It is one of the things that makes us most dangerous to others and to ourselves.” When we cling to our sense of ourselves as good, despite evidence to the contrary, we have turned our goodness into a sacred idol.
