How Do We Think About the Bible From a Philosophical Point of View?
I think the Bible can serve as a starting point in exploring philosophical questions; it certainly did for me, and probably has for a lot of people raised in the Church. If anything, it still acts more as an irrational specter in the back of my mind when I address philosophical questions. I still find myself thinking in it's terms; "I'm too selfish", "I judge others too quickly", "I don't love others enough", etc.
As other people pointed out, whatever philosophical information one might be able to glean from the Bible is generally couched in a lot of interpretation; in other words, it
requires rigorous interpretation to get anywhere. There is actually a lot of very rich stuff to be found; The Art of Biblical Poetry by Robert Alter is a fascinating exposition on that topic and is still to this day an influence on how I create music as an artist. Stories from the Old Testament such as Job, Jacob wrestling with the angel, and God cutting in half sacrificial offerings made to him (which is interpreted Messianically in Christianity) are deeply rich with suggestive meaning and can hold their own with not only other religious texts but with philosophical texts and great art as well.
So I think it's possible to glean valuable stuff from the Bible, in the same way other religious texts have value. It just carries such an ideological weight with it in the Western world that a middle position such as the one you're attempting to hold is rare and often attacked from both sides.
I've recently been obsessed with learning about Nag Hammadi and early church history. Fascinating to what extent there appears to have been a political bent or power struggle that gave birth to orthodoxy. The Gospel of Thomas in particular has some interesting statements, such as "do not tell lies and do not do what you hate." Sounds good to me...
