"Facts witness to the reality that [Christians] have abandoned God, that they have entered the world and become one with the world. Whatever the world considers praiseworthy ... vanity, comfort, wealth, fancy notions, blasphemies — the Christians, too, praise with one accord, quite blatantly without shame and without conscience. We can find with difficulty one man in a thousand who does not conform himself to the world. For this reason authority is necessary for the pagan world, since a man of weak faith will not be better than a pagan. A world contrary to God must be kept within bounds by the world’s sword."
