It is this American theology that gave rise to ideas like "the Rapture," an "end of the world" event that Christians prior to the existence of the United States, never really even imagined, but which in this American religious tradition is understood to be "right there in the Bible" by those holding this theology and (usually unconsciously, unless they've seriously studied the historical roots of their own movement) superimposed onto the text of Scripture itself. Oddly, in this way, these people become exactly that which they strongly fear: people who impose and value a human tradition over and above a reverence for Scripture itself. Dispensationalist Christianity has created an entire industry based upon ever-revised predictions of things like the timing of the end of the world, or the identity of the figure in the New Testament called the Anti-Christ. As various world calamities and horrific figures come and go (Lenin, Stalin, Hitler, Hussein, etc.) a new batch of best-selling books appears as people work feverishly to "decode" the Scriptures and produce the correct information about The End. That people caught up in this theology and spirituality don't start noticing, over the decades, that it is an industry (one that can make a few people no small amount of money) is one of the things that boggles my imagination.
But here's the real clincher: I'm particularly amazed that it is those Christians who tend to describe themselves as "Bible-believing" who particularly get caught up in these games. Protestant theologies that lean toward the fundamentalist are based off of a theory of Scripture that tends toward the strictest – and often distortingly literal – idea of an "inerrant" inspiration of Scripture. That is, these theologies tend to understand God as providing the text of the Jewish and Christian Scriptures in such a way that allows for little, if any, contribution of the writers' historical and cultural limitations in the text. (That's my quick stab at a description: it really is, historically and theologically, a complex story and set of ideas.) So these sorts of Christians identify themselves as especially or distinctively faithful to what they understand as the most basic, honest or literal sense of the text.
I say that I'm "amazed" that it is Christians who particularly identify themselves as "Bible-believing" that go in for these sorts of predictions, or have created an industry around them, because the New Testament so clearly warns off anyone from trying this sort of thing. Jesus himself says his return will be "like a thief in the night," or that "no one knows the day or hour when these things will happen, not even the angels in heaven or the Son himself." Paul commented on the futility of trying to guess "times and dates" for this very reason. And yet, a portion of American Christianity has turned this into the center of their focus and spirituality, spinning around these questions over and over again. If I'm going to take Jesus literally, I find myself thinking that these widely-announced "end of the world" dates are probably the very best time to get out there and rob a convenience store, with time for a change of heart and honest repentance later on.
"Bible-believing Christians?" I wish! Silliness like this sort of avoiding the obvious to decode the imagined is another distraction from Christianity's real credibility.
