I don't think that Huck ever embraces Christianity in the more typical church-like form, but he does come to understand a God as he discovers Him. Here are some quotes that indicate this postion:
It's lovely to live on a raft. We had the sky up there, all speckled with stars, and we used to lay on our backs and look up at them, and discuss about whether they was made or only just happened. (Ch 19) God in nature, not the hell-and-brimstone God Huck knows.
Pray for me! I reckoned if she knowed me she'd take a job that was more nearer her size. But I bet she done it, just the same--she was just that kind. She had the grit to pray for Judus if she took the notion--there warn't no back-down to her, I judge. (Ch 28) Strong people stand by their beliefs.
I hain't ever seen her since that time that I see her go out of that door; no, I hain't ever seen her since, but I reckon I've thought of her a many and a many a million times, and of her saying she would pray for me; and if ever I'd a thought it would do any good for me to pray for HER, blamed if I wouldn't a done it or bust.(Ch 28) Valuing people by their actions not their words
. . . there warn't anybody at the church, except maybe a hog or two, for there warn't any lock on the door, and hogs likes a puncheon floor in summer-time because it's cool. If you notice, most folks don't go to church only when they've got to; but a hog is different. (Ch 26) True motivation vs. false
Music is a good thing; and after all that soul-butter and hogwash I never see it freshen up things so, and sound so honest and bully. (Ch 25) True inspirtation vs. false
Well, it made me sick to see it; and I was sorry for them poor pitiful rascals, it seemed like I couldn't ever feel any hardness against them any more in the world. It was a dreadful thing to see. Human beings can be awful cruel to one another." Chapter 33 Man's inhumanity to man
Just because you’re taught that something’s right and everyone believes it’s right, it don’t make it right.” True valus
All right, then, I’ll go to hell. (Ch 31) True values
