"For a generation that thinks it approves of those who challenge the conventional wisdom, it can come as quite a shock when someone actually does it. In this book, Peter Leithart takes up the daunting challenge of defending Constantine, and he does it with biblical grace, deep wisdom, profound learning and scholarship that has let the clutch out. This is a magnificent book."

"An excellent writer with a flair for the dramatic, Peter Leithart is also one of the most incisive current thinkers on questions of theology and politics. In this book, Leithart helpfully complicates Christian history, and thereby helps theologians recover the riches of more than a millennium of Christian life too easily dismissed as 'Constantinian.' If the Holy Spirit did not simply go on holiday during that period, we must find ways to appreciate Christendom. Any worthwhile political theology today cannot fail to take Leithart's argument seriously."

"There have been of late a splurge of populist history books damning Constantine the Great as the villain of the piece. Almost without exception they have drawn their picture of this most complex and complicated of late-antique Roman emperors from secondhand, clichéd and hackneyed books of an older generation, adding their own clichés in the process. Constantine has been sketched luridly, as the man who corrupted Christianity either by financial or military means. At long last we have here, in Peter Leithart, a writer who knows how to tell a lively story but is also no mean shakes as a scholarly historian. This intelligent and sensitive treatment of one of the great military emperors of Rome is a trustworthy entrée into Roman history that loses none of the romance and rambunctiousness of the events of the era of the civil war, but which also explains why Constantine matters: why he was important to the ancient world, why he matters to the development of Christianity (a catalyst in its movement from small sect to world-embracing cultural force). It does not whitewash or damn on the basis of a preset ideology, but it certainly does explain why Constantine gained from the Christians the epithet 'The Great.' For setting the record straight, and for providing a sense of the complicated lay of the land, this book comes most highly recommended."

"Too many people, for far too long, have been able to murmur the awful word Constantine, knowing that the shudder it produces will absolve them from the need to think through how the church and the powers of the world actually relate, let alone construct a coherent historical or theological argument on the subject. Peter Leithart challenges all this, and forces us to face the question of what Constantine's settlement actually was, and meant. Few will agree with everything he says. All will benefit enormously from this challenge to easygoing received 'wisdom.'"
