Orthodoxy is idolatry if it means holding the 'correct opinions about God' - 'fundamentalism' is the most extreme and salient example of such idolatry - but not if it means holding faith in the right way, that is, not holding it at all but being held by God, in love and service. Theology is idolatry if it means what we say about God instead of letting ourselves be addressed by what God has to say to us. Faith is idolatrous if it is rigidly self-certain but not if it is softened in the waters of 'doubt.
