I have mentioned the qualitative difference between Christianity as an ethic and Christianity as an identity. Christian ethics goes steadfastly against the grain of what we consider human nature: the first will be last, to him who asks give, turn the other cheek, judge not. Identity on the other hand appeals to a constellation of the worst human impulses. It is worse than ordinary tribalism because it assumes a more than virtuous “us” on one side and on the other a “them” who are very doubtful indeed, who are in fact a threat to all we hold dear.
