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.
