For quite some time, I had been meaning to refer to a couple (now a few) useful sites for the study of Paul of Tarsus, a.k.a. the apostle Paul.
There is an extensive website on Paul by the late J. Peter Bercovitz (University of Edinburgh): “As Paul tells it . . . “. There you can read about a variety of important historical issues surrounding this self-proclaimed apostle (through the lens of one particular scholar’s historical interpretations, of course).
Another important issue in the study of Paul is the question of who were the followers of Jesus that Paul opposed. Jerry Sumney has done extensive research on the question of Paul’s opponents, and he has also done a brief web write-up for the Bible and Interpretation website: Who are those “servants of Satan”? There are many other useful articles on that same website, which I may come back to another time.
A third very useful site is The Paul Page: Dedicated to the New Perspective on Paul (by Mark M. Mattison). There you will find brief discussions and many links to resources regarding Paul within the context of second-temple Judaism. Scholars such as E. P. Sanders have been instrumental in revising our view of Judaism in Paul’s time and Paul’s relation to the various groups within Judaism; this view is known as the “new persepective”, which is very well explained on that website.
