"I think we must fully face the fact that when Christianity does not make a man very much better, it makes him very much worse. It is, paradoxically, dangerous to draw nearer to God. Doesn't one find in one's own experience that every advance (if one ever has advances) in the spiritual life opens to one the possibility of blacker sins as well as brighter virtues? Conversion may make of one who was, if no better, no worse than an animal, something like a devil. Satan was an angel."
