The Mission to the Jews: Why It Probably Succeeded"Perhaps only a sociologist would be foolish enough to suggest that, contrary to the received wisdom, Jewish Christianity played a central role until much later in the rise of Christianity— that not only was it the Jews of the diaspora who provided the initial basis for church growth during the first and early second centuries, but that Jews continued as a significant source of Christian converts until at least as late as the fourth century and that Jewish Christianity was still significant in the fifth century. In any event, that is the argument I shall make in this chapter."
Conversion and Christian Growth"...[A]ll questions concerning the rise of Christianity are one: How was it done? How did a tiny and obscure messianic movement from the edge of the Roman Empire dislodge classical paganism and become the dominant faith of Western civilization? Although this is the only question, it requires many answers—no one thing led to the triumph of Christianity...[I]n this chapter I will pose the question in a more precise way than has been done. First, I shall explore the arithmetic of growth to see more clearly the task that had to be accomplished...Having established a plausible growth curve for the rise of Christianity, I will review sociological knowledge of the process by which people convert to new religions in order to infer certain requirements concerning social relations between Christians and the surrounding Greco-Roman world. The chapter concludes with a discussion of the legitimate uses of social scientific theories to reconstruct history in the absence of adequate information on what actually occurred."
