It looks like the next phase in the study of Paul, after the New Perspective on Paul and Paul within Judaism, will be Paul (within Judaism) within paganism. See, for example, Paul Within Paganism: Restoring the Mediterranean Context to the Apostle, edited by Chantziantoniou, Fredriksen, and Young (2025), which presents “a florilegium of essays tracing the various ways in which Paul’s Jewish religious program is native to the ancient Mediterranean” (xi). The British New Testament Society conference this year will have a session on the book and related themes, to which I will be contributing.
