This work provides a survey of the history of the earliest Christian church in the period up to the fall of Jerusalem. It concentrates on: the figure of Paul; judicious and critical use of information in the Book of Acts; Judaizing versions of Christianity; and the Johannine tradition. The approach steers a middle way between an over-simplified account which fails to warn students where scholarly opinion is divided, and an in-depth academic study which attempts to document and discuss every hypothesis. Wedderburn focuses on aspects of central importance: the changing shape of church life and developing Christianity in relation to the Roman Empire and to Judaism. This book seeks to draw together and make more readily accessible many new insights gained from an enormous range of recent scholarly studies in German and English, and places them in the context of a more general account.
