Well, this has started me googling like a mad person. It's fascinating, what some folks believe. I was just reading Wiki and got this:
QUOTE
Wiki: The term resurrection of the dead is generally used to refer to the idea that the dead bodies of all or some of humanity will be reformed and rejoined with the soul at the end of the world.
I don't know quite how to take that. If we die and are judged then, does that mean that we'll be returned to our bodies and judged again? I shall feel like a yo-yo.
And imagine how these folks felt:
QUOTE
William Miller and the Millerite Movement expected the second coming on October 22, 1844. The fact that this failed to happen the way people were expecting was later referred to as the Great Disappointment. Some Millerites continued to set dates; others founded the Seventh-day Adventist Church and the Advent Christian Church, which continued to expect the Second Coming but no longer set dates for it.
The Great Disappointment... bit of an understatement.

I like this one:
QUOTE
Televangelist Jack Van Impe has, over the years, predicted many specific years and dates for the second coming of Jesus, but has continued to move his prediction later. Many of these dates have already passed, and he recently pointed to 2012 as a possible date for the second coming. Van Impe no longer claims to know the exact date of the Second Coming, but quotes verses which imply that mankind should know when the second coming is near.
2012 isn't the date for Jesus' return... it's the year when aliens colonize the earth, as anyone who watches the X-Files will know.
