Such arguments remind me of a scene from Woody Allen's movie Manhattan, where a group of people is talking about sex at a cocktail party and one woman says that her doctor told her she had been having the wrong kind of orgasm. Woody Allen's character responds by saying, “Did you have the wrong kind? Really? I've never had the wrong kind. Never, ever. My worst one was right on the money.” Grace works the same way. It is what it is and it's always right on the money. You can call it what you like, categorize it, vivisect it, qualify, quantify, or dismiss it, and none of it will make grace anything other than precisely what grace is: audacious, unwarranted, and unlimited.
