This book is the first exploration of the remarkable odyssey of Thomas Aquinas in the Orthodox Christian world, from the Byzantine to the modern era. Aquinas was received with astonishing enthusiasm across the Byzantine theological spectrum. By contrast, modern Orthodox readings of Aquinas have been resoundingly negative, routinely presenting Aquinas as the archetype of as a specifically Western form of theology against which the Orthodox East must set its face. Basing itself primarily on a close study of the Byzantine reception of Thomas, this study rejects such hackneyed dichotomies, arguing instead for a properly catholic or universal construal of Orthodoxy – one in which Thomas might once again find a place.
