"I ain’t gonna baptize. I’m gonna work in the fiel’s, the green fiel’s, an’ I’m gonna be near to folks. I ain’t gonna try and teach em’ nothin’. I’m gonna try to learn. Gonna learn why the folks walks in the grass, gonna hear ’em talk, gonna hear ’em sing. Gonna listen to kids eatin’ mush. Gonna hear husban’ and wife a-poundin’ the mattress in the night. Gonna eat with ’em and learn." His eyes were wet and shining. "Gonna lay in the grass, open an’ honest, with anybody that’ll have me. Gonna cuss an’ swear an’ hear the poetry of folks talkin’. All that’s holy, all that’s what I didn’ understan’. All them things is the good things".
– John Steinbeck
The Grapes of Wrath, Chapter 10. Casy may have lost his religion as a follower of organized Christianity. But he has found another one, in this humanist view of the world. To Casy all the everyday details of life are what’s holy. Married couples making love, Casy laying with a girl on the grass, cursing and swearing, talking with people, singing and working in the fields. These are all holy to Casy, who believes sex to be a spiritual experience. He decides that he will no longer be a preacher or baptize people. He will be be one of the people, the community of migrants, and learn from them.
