“The ultimate triumph of Christianity was aided by the internal drive within Roman paganism toward some kind of monotheism. By 150 A.D., whatever vitality had once existed in ancient polytheism had mostly declined, and the gods played little or no role in individual lives. The state temples to the old gods became civic centers rather than religious entities."But paganism went about reforming itself. It drew upon the Alexandrian mystical form of Platonism, taught by Plotinus -- what we call Neoplatonism -- to conjure an image of the deity as a single spiritual fountain of life that fructifies the world."This Neoplatonic monotheism became popular in aristocratic circles in fourth-century Rome and gave such renewed vitality to paganism that the triumph of Christianity had to be bolstered by state proscription of this latter-day monotheistic paganism. By 390, Roman paganism was almost as close to monotheism as was Christianity.”

“Judaism was a legal religion in the Roman Empire; Christianity was not until the first Christian emperor ascended the throne in the fourth century A.D. There were periodic persecutions of the Christians by the imperial state and local officials. The resulting martyrs, often upper-class women of unusual devotion, only served to draw more attention and converts to the Church.”

“The most important fact to know about the Christian Church in the two hundred years after Jesus' death is that only at the end of this period did the Church comprise as many people as the far-flung Jewish community numbered (five million) in the Roman Empire. Christianity developed an intense rivalry with Judaism, and for many decades was compared to the Jews as a minority. This accounts for the intense anti-Semitism that became enshrined in Christianity by 200 A.D. ”

“The mindset of antiquity lacked economic science and sociological theory. The ancients did rather well with political narrative, although, except for Thucydides, no first-rate political annalist and analyst emerged from the literary populace. But the ancients never showed a capacity, or even an inclination, to examine closely the urban world they themselves inhabited."Neither, however, was the medieval world in the 500s through the 1500s, which succeeded antiquity, much better at economics and sociology. It was only in the eighteenth and early nineteenth centuries that this kind of thinking emerged with Adam Smith and Alexis de Tocqueville in response to industrial and political revolutions."What interested the urban dwellers of antiquity were the gods. During the Hellenistic and Roman eras the theoretical capacity of the literate urban population was given over to thinking about the nature of divinity. The chief theological formats were polytheism (many gods); monotheism (one god); dualism (two dogs, one good, the other evil); and dying and reborn savior gods that could also be fitted into the other three categories of divinity.”

“Christian legend later claimed that Peter also went to Rome and there became head of the Christian community, that is, a bishop. Both Peter and Paul, according to the Catholic version, died as martyrs in the Eternal City. Paul definitely went to Rome, and may have been martyred there. But that Peter, a very devout, timid Jewish fisherman, uneducated, and knowing little or no Greek, and no Latin, would have ended in Rome is most unlikely. Thus the whole claim of later bishops of Rome (the popes) that their authority in the Church was derived from its alleged first bishop, Saint Peter, was likely wishful thinking, if not an absolute hoax, that developed in the late second century A.D.”

“At this point, a social flaw that always existed with regard to the [Roman] aristocrats in their townhouses became more evident. No longer finding urban life as secure and amenable as in the early empire, the landed rich gave primacy not to their urban mansions but to their country estates, making the latter their principal residences. The dominant forces in urban life increasingly became the bishops and cathedral clergy.”

“Saint Paul was proud of his Roman citizenship, and his letter to various Christian communities in the empire presupposed an effective communications system that only Roman government, law, and military might allowed."The Church's administration evolved as the imperial government's structured was modified over time. An archbishop ruled a large territory that the Romans called a province. A bishop ruled a diocese, a smaller Roman administrative unit dominated by a large city."The capitals of the eastern and western parts of the empire -- Constantinople and Rome -- came in time to signify unusual and superior power for the bishops resident there. When the Roman state was dissolved in the Latin-speaking world around 458 A.D., the pope replaced the emperor as the political leader of the Eternal City.”
