Let the Christian remain in the world, not because of the good gifts of creation, nor because of his responsibility for the course of the world, but for the sake of the Church. Let him remain in the world to engage in frontal assault on it, and let him live the life of his secular calling in order to show himself as a stranger in the world all the more. But that is only possible if we are visible members of the Church. The antithesis between the world and the Church must be borne out in the world. That was the purpose of the incarnation. That is why Christ died among his enemies. That is the reason and the only reason why the slave must remain a slave and the Christian remain subject to the powers that be.
