Revelation … unavoidably challenges the institution and established power, no matter what form this may take. But the adulteration by political power has changed all this. Christianity has become a religion of conformity, of integration into the social body. It has come to be regarded as useful for social cohesion (the exact opposite of what it is in its source and truth).
