Jason Staples has a good blog post here dealing with one of the passages used by people like Harold Camping to justify their nonsense about the 'Rapture': http://www.jasonstaples.com/blog/2011/two-will-be-taken-one-will-be-left-misinterpreted-bible-passages-8-2478? . He's perfectly correct; the sense of Matthew 24:40 is as though the police raid a building, arrest one person, and leave another. You definitely don't want to be taken! It never ceases to amaze me how the church (meaning the community, led by the nose in this case) sometimes manages to interpret the Bible as meaning the precise opposite of what it says! Of course, the traditional translation here isn't very helpful, but that's often the case, and we need to be aware that we're not reading the original text.
And here's a post from the Beaker Folk summing up what apocalyptic is really about: http://cyber-coenobites.blogspot.com/2011/05/riding-bow-wave-of-rapture.html .
