The Two Approaches in Pauline Interpretation

I think William Campbell has offered an insightful observation about the two competing approaches and resultant theologies in Pauline scholarship:

There are in fact two theologies of Paul in conflict. One derives from post-Augustine Christian theological terms and disputes which are considered normative even for Paul. The other seeks to avoid the overt theological conceptualization, to concentrate on the concrete realities of Israel and the nations in relation to God, and to limit discussion to the meaning and terminology of the contextualized letters of Paul.
