Dave - this is David Wayne from Glen Burnie Evangelical Pres in Glen Burnie, MD USA - I also have a blog called Jollyblogger - and I am friends with Adrian Warnock. i was looking for an e-mail and couldn't find one so i thought i would leave a comment on this. I think you and i may be kindred spirits on this issue of the nephilim/rephaim. Here in the states, those who are more conservative theologically tend to take a somewhat less than supernatural approach to Genesis 6 and nephilim, rephaim, and giants. Looks like you take the angelic view, which I do to. I'd love to correspond with you a bit on this if you have the time. don't know if you could e-mail me from the info left on the comment but as I say i would love to chat with you about this.
Seems we might well be! Glad to correspond. Not sure that I have much more insight than Dan Hames has posted but it's good to bat things around.
I'm happy to chat a little more on this if it's of interest. Might perhaps look at blogging some.
