Least of the Apostles is a study of Paul's relation, both in his ministry and through his epistles, to the rest of apostolic Christianity. Studies relating Paul to Judaism, the Roman empire, or Greco-Roman philosophy abound, we adopt the comparatively neglected approach of relating Paul specifically to his fellow apostles. The first three chapters explore the influence on Paul of sources from the earliest church (James and his circle, the "apostolic decree, " and proto-Synoptic traditions), while the final three explore Paul's influence on Hebrews, Luke and John, and the Petrine Epistles. We conclude by considering the implications of these findings for New Testament theology.
