Several recent studies have argued for the importance of democratic practices and ideology for a proper understanding of the issues and debates reflected in Paul's Corinthian correspondence. This new perspective stands in tension with older scholarship which emphasised the role of patronage in the structure and dynamics of the house churches that made up the ekklēsia of Christ-believers at Corinth. This essay draws upon new research into the political sociology of Greek cities in the early Empire, which highlights evidence of the continuing vitality of democratic assemblies (ekklēsiai) in the first and second centuries, despite the limitations imposed upon local autonomy by Roman rule. Special attention is devoted to the epigraphic evidence of first-century Corinth, whose political institutions and social relations were those of a Roman colony. The essay seeks to ascertain whether the politics of the Christ groups mimicked those of the city in which they were located or represented an alternative.
