The planned series "Early Christian Centers" (Tübingen: Mohr Siebeck) investigates the emergence and institutionalization of early Christianity from its beginnings on into the 4th cent. CE in Alexandria, Antioch, Athens, Ephesus, Jerusalem, Corinth, Philippi, Rome, and Thessalonica. Through a consistently applied local-historical approach, a team of international experts will inquire into the ways in which early Christian groups were embedded in their urban cultural-religious milieu and how they developed into an influential and dominant entity.
