Thascius Caecilius Cyprianus believed fervently that his conversion experience had been a passage from the darkness of the world of Graeco-Roman paganism to his new vision of Christianity. But Cyprian's response as bishop to the Decian persecution was to be informed by the pagan culture that he had rejected so completely. His view of church order also owed much to Roman jurisprudential principles of legitimate authority exercised within a sacred boundary spatially and geographically defined. Given the highly fragmented state of the non-Christian sources for this period, Cyprian is often the only really contemporary primary source for the events through which he lived. In this 2010 book, Allen Brent contributes to our understanding both of Roman history in the mid-third century and of the enduring model of church order that developed in that period.
