With remarkable breadth of vision encompassing such diverse phenomena as Sufi mysticism, the Rig-Veda, Australian tribal religions, and medieval religious poetry Prof. Arseniev indicates both the decisive significance of the Christian massage and the historical preparation for it. Based upon a series of lectures delivered at St Vladimir's Seminary in courses on Christian apologetics and Orthodox mysticism, these essays present an Orthodox evaluation of 'world religions.' They constitute an inspiring introduction to man's universal quest for God and its fulfillment in the Gospel.Nicholas Arseniev
