Julien M. Ogereau explores the socio-economic dimension of Paul's koinonia with the Philippians from a Graeco-Roman perspective. After conducting a rigorous philological study of the business terminology Paul employs in Philippians in the light of documentary sources (papyri and inscriptions), he offers a thorough socio-economic reading of the letter that is informed by ancient cultural conventions. Challenging recent scholarship, Ogereau concludes that Paul's relationship with the Philippians followed the well-established pattern of economic partnerships ( koinonia/societas), whereby Paul supplied the ars and opera (skill and labour), while the Philippians contributed the pecunia (funds).
