The reference to Flannery O'Connor is apt, as he's a latter day O'Connor character himself: Christ-haunted, toying with grace, which may yet capture him with a terrible, transforming power, or which he may ultimately resist, to his own destruction. Those who're troubled by this post should consider its purpose: not to exalt the author as a moral exemplar, but as an inquiry into the war between good and evil that rages in every human heart wounded by original sin, including ours.
You said it far better than I could.
