Book excerpt: The Social Structure of the Early Christian Communities deals with a small number of topics which, in one way or another, have long attracted the attention of students of early Christianity. Above all, it is an attempt to investigate the social origins and the social positions of the early Christians. Recent studies are arriving at the conclusion, contrary to long-held views, that the primitive Christian communities, those which emerge after the first chapters of Acts, did not consist of the 'dregs of the populace'. However, in spite of the important work which is being done on the subject, few of the recent books concerned with such sociological issues go far beyond the New Testament age. What still requires investigation is the composition of the early communities from the first years of the mission to the Gentiles down to the age of Constantine, when large sections of the population, from all social classes, started joining the Christian churches.
