The author seeks to discuss all the evidence for the life of the early Christians in Ephesus from Paul to Ignatius, seen in the context of our knowledge of the city as a whole. Drawing on Paul's letters and the Acts of the Apostles, the author discusses the beginnings of the life of the early Christians in Ephesus, both before the Pauline mission and during that mission. He then shows that in the period from around 80-100CE there were a number of different groups in Ephesus who regarded themselves as Christians. Some key features of the life of each of these groups are discussed, as the evidence allows; this testifies to the diversity of early Christianity in Ephesus. It is also argued that the Pauline group and the Johannine group in Ephesus were distinct and separate communities, although they maintained non-hostile contact. Finally the information that Ignatius gives us about Christians in Ephesus in his time is discussed.
