Peter Brown writes for NYBooks.com:
A new history of Christianity traces its transformation over a thousand years from an enormous diversity of beliefs and practices to Catholic uniformity…
Peter Heather’s Christendom is a colossal book written by a colossus in the field. Aptly subtitled “The Triumph of a Religion,” it covers a millennium, from the conversion of the Roman emperor Constantine in 312 to the baptism of Grand Duke Mindaugas of Lithuania, the last pagan ruler in Europe, around 1250.
Heather resolutely rejects the romantic notion that Christianity rose to the top of late Roman society by its intrinsic merits alone, without the help of the powerful. His attitude is close to that of J.B. Bury, who argued that “it must never be forgotten that Constantine’s revolution was perhaps the most audacious act ever committed by an autocrat in disregard and defiance of the vast majority of his subjects.”
To justify this view, Heather offers a cogent analysis of the structure of Roman upper-class society and its relation to the Roman state—a relation that made elites peculiarly vulnerable to pressure from a Christian court. If pressure was exercised by Constantine and his Christian successors on the wider population, it was the gentle violence of a state that lacked the strength and organizational capacity of modern dictatorships. The late Roman state was not “a decadent Leviathan,” as many scholars from the 1930s onward deemed it to be. These scholars saw the later empire as a warning for their own society, faced with the rise of totalitarian states in Europe and with what struck some of them as the ominous expansion of government associated in America with the New Deal. As a result, they greatly exaggerated the Roman Empire’s coercive powers.
Heather points out that the late Roman state could not enforce an ideology; it was too “rickety.” But it could seduce. Its immense ambitions depended on networks of friends and clients that stretched from the court to the lower reaches of the gentry in a never-ceasing waterfall of favors asked and favors received. If one wanted to get anything done, one had to please someone. And ideally this was someone who had pleased the emperor and those around him.
Once the emperor made plain that he was an orthodox Christian and that he would shut the “divine ears” to the petitions of heretics, Jews, and pagans, the message trickled down with surprising speed. A confessional state was born.
