"Principles are what people have instead of God. To be a Christian means among other things to be willing if necessary to sacrifice even your highest principles for God's or your neighbour's sake the way a Christian pacifist must be willing to pick up a baseball bat if there's no other way to stop a man from savagely beating a child. Jesus didn't forgive his executioners on principle but because in some unimaginable way he was able to love them. 'Principle' is an even duller word than 'Religion'."
