This volume's focus is threefold, thus corresponding to its tri-partite topical division: to analyze Eastern monasticism's unique place in the life transforming journey to theosis; Eastern monasticism's hospitality and mutual encounters with culture; and Eastern and Western monasticism's hospitality to Christian and non-Christian religions, including Buddhism, Hinduism and Islam (even though Islam does not have any monastic institution, its adherents have been historically in dialogue with Christian monastics and have the potential to achieve a spiritual affinity with monks of other religious traditions). The three parts of the volume share one unifying argument: monasticism's special call to spiritually symbiotic relationship or impact on the very socio-politic-historic structures of reality. The topics are explored from various standpoints which include historical, theological, and literary, providing both breath (application) and depth (conclusion) to the principal argument. The volume's overall intention is to help make monastic ecumenical engagement or its potential for inter-faith dialogue better known, appreciated, and relevant within inter-religious dialogue.
