NT Wright and the New Perspective on Paul

This is, in most part, a response to a question by Blake:
“What is your opinion on the New Perspective on Paul?”
I am, admittedly, Wrightian (as in NT Wright) in my understanding of Paul and will draw on his understanding of this controversial topic.*

The Church’s relationship to government has been historically messy. From the approved execution of Jesus by the Roman prefect Pontius Pilate, to the merging of Church and Government that lead to the violent Crusades and to the modern Christian struggle of political involvement in democracy, there have been differing views on what exactly is the “Biblical” relationship of the Church, Christians and government.

Have you ever read the New Testament’s use of Old Testament Scripture and became puzzled that the authors didn’t employ historical-grammatical exegesis on the text, but rather employed what looked like a metaphorical interpretation, mistranslation or an odd application of the Old Testament that disregarded the Old Testament context? (Or is that just me?)
