No, no, the rapture is in Revelations.... kind of. I'm pretty sure these people have never, ever read what it actually says there, though. Because, honestly.... unless you're of Jewish decent, theoretically you're not going. It's specifically something for the tribes of Israel. And only some subsection of them. There's a number given. It's a lot smaller than the number of fundamentalist Christians in the US. For people all into literalism you'd think some of them would have noticed these issues.

Though I think there was some other passage in Revelations that they've twisted into extending this to cover them. But.... yeah.
