John Chrysostom, or "Golden Mouth", was a famous ascetic and preacher of the fourth/fifth century, a controversial bishop of Constantinople, and a brilliant orator - hence the epithet. This is the first comprehensive study of him in the English language in over a century. In the early chapters John Kelly highlights Chrysostom's youthful experiments with asceticism at Antioch in Syria, his six years as a monk and then a recluse in the nearby mountains, and his influential role as Antioch's leading preacher. The central section of the book shows him as a fearlessly outspoken populist bishop of the capital. Kelly focuses on his authoritarian style, his interventions in political crises, and his clashes with the Empress Eudoxia, as well as his efforts to promote the primacy of the see of Constantinople in the east. The final chapters reconstruct the plots that led to Chrysostom's downfall, the drama of his trial, and his exile and death. Golden Mouth also provides fresh analyses of Chrysostom's principal treatises and public addresses, and discussions of his views on monasticism, sexuality and marriage, education, and suffering.
