Hi Spade,
It took a while to understand the tie in and why this subject is so important. Maybe next time you can post the watchtower information.
Ah, you're pretty new around here, I see :-) The reason nobody posted the WT information on this thread is that most of us already know the WT position inside-out.
If every Babylonian archeological remain excavated were synchronous with the Biblical timetable then what?
This is where you misunderstand, I think.
The issue is the WTS' interpretations of certain biblical passages that are made to fit with their own timeline, which clashes with certain other biblical texts and the archaeological records. (Mary has highlighted one of the fundamental problems with the WTS' hermeneutic.) It isn't a case of finding some missing archaeological remains that will overturn the established Babylonian chronology because thousands of remains have already been found that have led archaeologists and chronologists to the conclusions they have. Secular history and the Bible synchronize pretty well with each other for that time period when all the evidence is taken into consideration.
Hypothetically, however, if archaeologists had found that all the ancient records upheld the WTS' dating system, and that Jerusalem really did fall in 607/6 BCE, then WT critics wouldn't be kicking up a stink about this.
I think it's obvious that people here do not want Judgment Day to come that's why you go to great lenths to undermine the Bible. ...
Well, there is a smorgasbord of beliefs on this board. However, this specific controversy about chronology and biblical timelines is not about 'undermining the Bible' but everything to do with harmonizing the Bible's testimony and the historical record.
You do realise that the WTS is on its own with this, don't you? Nobody, apart from groups and the occasional person who have/have had an affiliation with the WTS, agrees that Jerusalem was destroyed in 607/6 BCE. Even Christian academics, who believe in the authority and truthfulness of the Bible, disagree with the WTS' timeline. Doesn't that give you pause for thought?
And there is a bigger reason why this topic is important that you may not yet be aware of. The 607/1914 teaching is foundational to the JW leadership's claims to divinely-given authority, of being specially chosen by God (in 1918/19) to be His sole channel for dispensing spiritual truth. It is this notion that will, if your wife continues to progress in her study, ultimately lead her to being 'locked' into this religion.
