Re: The Kennedy assassination is still sending a chill wind thru the heart of American society and politics.
I wish you well in your enterprise, and yes, the jargon surrounding the subject can sometimes be more of a hindrance than a help. For example, a premillenialist would call me an amillenialist, but I wouldn't, coz I most emphatically do believe in a millenium - just not their kinda millenium. I'm only an amillenialist in the very narrow sense that I reject an earthly kingdom following Jesus' return. Then again, so do postmillenialists and preterists, so it's not as if all these ridiculous labels have advanced our understanding in any meaningful way.
As for the full-blown preterists, no, frustration is not a word I would use. They have some serious exegetical problems with which to contend. For example, IIThess. 1:7-10 is one of the plainest, most powerful and all-encompassing statements on the second advent to be found anywhere in the Bible. It is written in prose, not apocalyptic, so there is next to no wriggle-room as far as interpretation is concerned. If you call into question its plain meaning, then you must also call into question everything else from the virgin birth to the resurrection.
To be consistent, preterists have to declare themselves agnostic at best on practically every fundamental doctrine of our faith. That's not a very happy place in which to find yourself. As a side note, that single reference alone also shoots a hole the size of a house through every form of chiliasm going. When the NT calls it the last day, it actually does mean the last day, period. There can be no more history after 'the last day' - only eternity can follow. What could be simpler than that?
