Byzantine Theology, Hesychasm and the Orthodox Liturgical Legacy

Byzantine Greek theological literature produced sustained and highly technical doctrinal debate across the empire's history, including the Christological controversies that split the Byzantine church from the Oriental Orthodox churches following Chalcedon in 451, the iconoclasm controversy over the legitimacy of religious images that convulsed Byzantine religious life through the eighth and ninth centuries before iconodule theology prevailed, and the fourteenth-century Hesychast controversy, in which the monk Gregory Palamas defended contemplative monastic prayer practices and a distinction between God's unknowable essence and knowable energies, a formulation that became authoritative Orthodox theology and remains influential in modern Eastern Orthodox spirituality. Byzantine Greek liturgical texts, hymnody and monastic literature continue to be studied directly by Orthodox seminarians and scholars, and Mount Athos, the autonomous Orthodox monastic community in Greece, maintains manuscript collections and living scholarly engagement with Byzantine Greek theological and liturgical texts largely unbroken since the Byzantine period itself, giving Byzantine Greek a continuous institutional life within Orthodox Christianity distinct from the purely academic study it receives in secular universities.
