I doubt thats what W meant. The common literal interpretation of the Bible in some Christian sects does not, in fact, have any idea of multi-dimensionality, not does it acknowledge that there is a probable gulf of understanding. Thats what St. Augustine was getting at.
Bush was addressing the idea of a literal reading in its common and very crude sense. In this his opinion is very conventional.
And is used by our enemies, and their name is Legion, against us.
W is a Christian like W is a conservative; lukewarm.
