Because of its belief in one God the church found itself engaged in a struggle with the Roman state which permitted no compromise and from which eventually only one of the two parties would emerge victorious. The Martyrdom of Polycarp sets out quite clearly both the issue at stakeLord Christ versus Lord Caesarand the states (as well as the general populations) view of Christians as disloyal atheists who threatened the well-being of the empire.1
The Christian was faced with a cruel dilemma. His safety was assured only by preparedness, in time of need, to identify Himself either with pagan society, by sacrifice to the emperor and the expected participation in the religious aspects of guilds and social life. . . or with Judaism on whatever terms would gain him acceptance in the synagogue, that is, probably, at least an implicit denial of his Lord. The first inducement was naturally strongest in those places where the pressures of authority and pagan society were most direct (Pergamum and Thyatira, and also Ephesus, where it was steadfastly rejected): the synagogues of Satan brought the opposite threat against those who scorned the pagan compromise (Smyrna and Philadelphia, and perhaps the commended minority in Sardis). The situation also introduced a new occasion of disunion between Jewish and Gentile Christians, on whom it impinged differently.2
