Remember that the “heart of humanity is ashes,” according to the estimate of God, and that “the very wisdom of the world is foolishness.” … Then, if the heretic seeks refuge in the depraved thoughts of the vulgar or the imaginations of the world, I must say to him, “Part company with the heathen, O heretic!” For although you are all agreed in imagining a God, yet while you do so in the name of Christ, so long as you deem yourself a Christian, you are a different person from a heathen. So give the nonbeliever back his own view of things, since he does not himself learn from yours. Why lean on a blind guide, if you have eyes of your own? Why be clothed by one who is naked, if you have put on Christ? - "On the Resurrection of the Flesh 3"
