Good question by the way.
I'm sure there are lot of believers that don't feel their view of the bible to be literal but allegorical in nature I think most Catholics are not taking the bible literally.
Only fundy groups take every thing the bible says literally as unquestioning Truth the word of god almighty that must be obeyed or meet with god's wrath.
Which brings to mind why would a supreme Being require belief in his existence and make it a matter of life or death,, me smells a over zealous bigot for his deity of choice, writing down these words in a text to strike fear into the reader and take over his mind with more bull shit to follow.
