A short little primer on the New Perspective on Paul (NPP).
There's been a massive shift in New Testament scholarship, beginning more than 40 years ago, in which Biblical scholars of the NPP have been questioning the traditional Protestant interpretation of Paul's writings. The idea is that some of the main assumptions of Luther, and the theologians who came after him, are built on a mischaracterization of the Jewish religion, and the ignoring of the context in which the New Testament books were written. These misinterpretations were committed (unintentionally, of course) as Luther and others applied the scriptures to their present theological concerns and in the context of the Reformation, but without the knowledge of the first century cultural context surrounding the Bible which has recently been so helpful in interpreting New Testament texts. For example one such assumption is that the Judaism of Paul's day was a religion based on legalism--that one achieved salvation through perfect obedience to the law--a characterization that has been demonstrated to be completely false. Saunders, Wright, and others of the NPP have made a strong challenge that Paul's gospel was not primarily about salvation by faith vs. works righteousness, but was more about the salvation of God being opened up to Jew and Gentile alike, without requiring the badges of Jewish identity, for example circumcision. This has, of course, ignited a firestorm among Protestant theologians, including a feisty exchange of books between N. T. Wright and the Neo-Calvinist writer, John Piper.
This book gives a succinct and helpful explanation of how the New Perspective on Paul (NPP) came about, what its chief points and evidences are (in all their variety), how its affecting the world of Biblical scholarship, and the arguments its opponents are making. While the author himself seems to have landed on the side of the NPP, the book seeks to be balanced in its portrayal of both sides.
I'd already been aware of the NPP debate and have my own perspective, but I still found this book quite helpful in its simplicity.
