The teachings of St Symeon (949-1022) created much controversy in Byzantium and led to his short-lived exile to Asia Minor in 1009. This book examines St Symeon from within the Byzantine mystical tradition, looking at him as both a highly personal and a very traditional ecclesiastical writer. For the first time in modern scholarship, this study explores St Symeon's attitude to Scripture and to church worship; his relations with his spiritual father, Symeon the Studite; and the Studite tradition in general.
