This book addresses change and continuity in late antique Eastern Christianity, as perceived through the lens of the categories of institutional religion and personal religion. The interaction between personal devotion and public identity reveals the creative aspects of a vibrant religious culture that altered the experience of Christians on both a spiritual and an institutional level. A close look at the interrelations between the personal and the institutional expressions of religion in this period attests to an ongoing revision of both the patristic literature and the monastic tradition. By approaching the period in terms of 'revision', the contributors discuss the mechanism of transformation in Eastern Christianity from a new perspective, discerning social and religious changes while navigating between the dynamics of personal and institutional religion.
