One Flew Over the Cuckoo's Nest question

No.

I don't see any reason to intepret this novel in such a way. Especially since religion often copies from much older religions. So what you see there might as well be a reurcurring theme. I bet the author only thought up that story.
Usually, when you create art you rarely figure out beforehand how people might interpret it. That's why people can write over ten pages about one picture by Picasso even if he himself probably only thought about making the picture unique when he painted it without thinking about means of interpretation.

This was actually brought up in the class I had to do this book for, I am searching for my notes now.

There is this one theorist who says that there are only seven different stories, that every story is a variation on the same thing.

Lots of people have had the theory about x number of plots.

Christopher Booker wrote a big book about seven plots but he is not very convincing, he can't actually find a single story that fits any of his plots properly and then blames the books and authors for them rather than the theory.

Um, i don't really see this story relating to any religious significance. It could, i guess, distantly be related in that way. If it is, i haven't noticed it at all, but i do like how you thought about it in that way. Cool thoughts!

Now that you mention it, I do think that this book could be a parallel to the Christ story. Randy symbols Christ and he has to save the patients from Nurse Ratched, the devil. He died for the patients, just like Christ died for our sins. I would have never picked up on this comparison, but I do think that Ken Kesey may have really meant it to play out that way.
