There is a huge gap between the vague God of philosphy and the mad old books, but no-one, theist or atheist sees it.

Saying no-one sees it is a bit of a leap. It's an argument I've often made when people resort to the god of the gaps type arguments - the god they're describing is not the god of their professed religion. I've seen the argument in other places as well - theists often claim Einstein as supporting their position which is a gross misrepresentation since what Einstein meant by 'god' was nothing like the god of any major religion. A number of prominent atheists have pointed that out.

Otherwise I agree with everything you say.
