The widely acclaimed comprehensive survey of the role of the medieval Orthodox Church in the Byzantine Empire (c.600-c.1453), by the late Professor J. M. Hussey. Discusses landmark events in ecclesiastical affairs, the influence of the Church on the West, its officials and organization, and the spirituality of laity, monks, and clergy. When Prof. Hussey's history of the Orthodox Church was published in 1986, it was immediately recognized as the standard treatment in English of its subject. Twenty years later, it is still the first book on the subject for any serious student.
