I've been reading various materials on this topic. This is really a fresh view that challenges a lot of traditional theological/philosophical thinking.
Remembering how our approach and philosophy affects how the Bible is interpreted, OT gives some really compelling insights to consider.
I am not "promoting" OT, but I have found that it gives better answers than the traditional Classical Theology on some things.
Here is a good "starter page" that describes what OT is. What are your thoughts?
