Athanasius of Alexandria

And what they now write proceeds not from any regard for the truth, as I said before, but rather they do it as in mockery and by a subterfuge, for the purpose of deceiving others. They hope that by sending about their letters they may engage the ears of the people to listen to these notions and so put off the time when they will be brought to trial. By concealing their impiety from observation, they try to make room to extend their heresy, which, "like a gangrene," eats its way everywhere.
