You might start with Chapter 31 of Adventures of Huckleberry Finn.  After
all, Huck decides quite firmly that he's going to ignore his conscience,
ignore the teachings of the church, and decides to "take up wickedness
again."
 In fact, he says to himself, "All right, then, I'll *go* to hell."

   Please read that chapter very carefully.  You may need to read it a few
times.  This passage, perhaps more than any other, will give you the spirit
of
Twain's "anti-Christian thoughts."
