Propositional or Thematic?

An unfortunate trend in biblical interpretion is to understand the bible in terms of propositions as opposed to themes. This is a closely related idea to reading the bible in terms of a narrative. I assume this error is mostly related to the enlightenment, but very well may be able to be traced all the way back to middle-platonic influences on the early church fathers. Specifically what I am thinking of is that we tend to read the bible as a set of lots and lots of propositions, that we assume will all fit together. Well, upon further examination this type of reading renders many problems. How can God ask people to love one another as the greatest commandment yet command the destruction of entire cultures? How can God know us before we were in the womb yet still allow the birth of Hitler, Dahmer, and Osteen? (Probably slightly unfair) Well, for the propositionalist he cannot without having to make some very unsavory distinctions about God's character, i.e. that by virtue of being God that he can do as he pleases without guilt. But then, why does God command a type of justice entirely contrary to his own behaviour? Again, more complications for the propositionalist. What if the bible is not a "95,000 Theses" but instead a narrative of God's interaction with mankind that is held together by a common theme, not a loosely aligned confederation of assumedly agreeable yet ontologically isolated propositions? Ok, after writing that I see that sentence needs some unpacking. What I've been noticing for a few years now is that the Bible makes alot more sense if we look at the theme of the WHOLE story rather than assuming that any proof text can be removed from its context and still be just as coherent in the scheme of reality? This book is not a set of static reflections of reality, but dynamic fluxuations that consitute reality.
This morning at church I was surprised with several visitors. They were a group of three teenage girls and their leader, a woman who is helping procude a Christian sitcom called Heavenly High. You can catch it on SkyAngel if your satellite provider carries the network. The idea for their program is they take typical highschool problems and then scour the bible for verses that prove the bible answers all of today's questions and is still relevant. Really? When I was in highschool this thing rolled around called "cloning". Well Heavenly High, let me know when that episode airs because I am still pretty uncertain when the bible ever mentions the matter. You can see where I am going with this. The bible is not a set of propositions that can be ripped from their context and forced into ours. We think this though because we think of reality as this staticity which exist beyond our own existence. Maybe not though. The bible certainly is dynamic and tells a dynamic story, contingent upon the context in which the characters of the bible participated. Tired head yet? Me too. Try to sort some of this out later on...
