Literary Dissidence

I am currently making an effort to re-read Mark Twain's Letters From the Earth. I strongly recommend it to anyone wishing to see Christian theology, as well as quite a few other things, dealt with in a most irreverent, at yet astute, manner.
Christians--especially closed-minded ones--be warned: The Creator is not spared a single shot, and this is not a Dean Martin roast. Be prepared to think, and laugh, hard one way or another.
