War in Heaven

This is a question asked on the moderated Charles Williams list. I would
appreciate hearing from CSL people about what he might have written/said
about it.

Question about the War in Heaven, and Principalities and Powers both good
and evil here on earth:
>I want to ask -- do you think that Lewis
> thought of the war he was depicting as real?
> Literally a war being played out before us then and
> now?

I can't find a reference to Lewis' thought on this. Just a reference to the
Book of Revelation where justice meted out by "the Blood of the Lamb" makes
the blood run cold. That Hideous Strength has some clues, perhaps.
And do any of you believe that there IS a spiritual war going on here on
earth? And/or in Heaven? And why?

I'm looking up the Scripture on "binding and loosing" which may enlighten.
But please comment on the matter of spiritual warfare.

Thanks so much.
Blessings,
Ann
