Dr. Kim Riddlebarger recently completed a series on the New Perspective on Paul. This audio is a very good introduction to these issues.
Part 1 – Why a New Perspective on Paul? What’s Wrong With the Old Perspective?.
Part 2 – The Attack Upon the “Lutheran” Paul — Krister Stendahl and the “Introspective Conscience”.
Part 3 – Pelagian Jews? E. P. Sanders, Grace v. Works and Second Temple Judaism.
Part 4 – Why Can’t We All Get Along? James D. G. Dunn on Jews and Gentiles in the Apostolic Church.
The series will continue in the near future.
