You buy "WordPerfect for Dummies" and then declare that book to be a commentary on how to understand and use WordPerfect. If you want to call that an "interpretation", go ahead, I guess. ;)
I can't think of a single concept which Paul introduces in his commentary which isn't fundamentally grounded in an OT mindset. I can think of *plenty* of ideas and motivations which have been ascribed to both Paul and Jesus which don't have that grounding, mostly along the lines of "behavior X means Y in 21st-century white American culture; therefore when Jesus or Paul did X it means Y". Appalling anthropology, akin to writing a "WordPerfect for Dummies" which only talks about MS Word.
