Before I start, I want to note my usual disclaimers regarding religion (i.e. I'm hoping not to offend, etc) and that this is not the forum for discussing views that do not have some Tolkien context.
The last book of Christian Bible is called
Revelation, or the Revelation to John or the Apocalypse of John. The book contains prophecy that, to me and others, details the fall of Jerusalem in 70 AD. Others see in the text a description of the end times, the end of the world, Armegeddon,
the Apocalypse. The book contains interesting descriptions of actors (persons, nations?) such as a dragon, a beast, along with a bunch of calamities and other (to me) metaphorical language. Also, it's been noted by those who study the book that there are many references back to the Old Testament.
Is it then coincidental that Tolkien's 'Notion Club papers' have someone 'dreaming' or having a vision about the destruction of a place, and that the history of that place would lead the reader back to even 'earlier time' tomes?
Hope that that's clear.
Another comparison would be those who see portents in the Notion Club papers and see doom coming in 2012.
Some Christians read Revelation in a different light, and with newspaper in hand, see doom like a wave coming over the horizon.
