In this book, Sarah Emanuel, a Jewish scholar of the New Testament, argues that Paul was not a universalist. Instead, Emanuel shows that, stemming from his Hellenistic Jewish worldview, Paul understood Jews as needing to maintain the law in Christ and gentiles as needing to abstain from the law in Christ. Both groups, in other words, needed to maintain particular ethnic difference in their Christ-following orientations lest they be "left behind" from Paul's imagined end of days.
Also argues that the way in which Paul understood these groups was through ethnonationalistic and hierarchical means. By "ethno-nationalistic," she means that Paul viewed the end of days as a new, Israel-centric nation requiring particular polyethniccultural affiliation: Jews for Christ and gentiles for Christ. By "hierarchical," she means that Paul valued Jews for Christ over gentiles for Christ (and also males over females and free persons over enslaved persons); after all, Paul's end of days was itself Israelcentered (i.e., Jewish-centered) with the God of Israel (i.e., the Jewish God) at the helm.
Finally, none of these beliefs made Paul exceptional in his Judaism. It made him average in his Judaism. Wrestling with Paul shows that scholars in a post-Holocaust world have often sanitized this ethnocentric exclusivism so as to make Paul ahistorically "good" for modern Jews and Judaism. It also shows that readers of Paul have--for millenia--made sense of him in light of contemporaneous attitudes toward Jews.
