Narsai († ca. 500) was a founding theologian of the Church of the East. Active first at the School of the Persians in Edessa and later at the School of Nisibis, Narsai creatively synthesized his native Syriac tradition with the newly translated works of Antiochene theology and exegesis. In a time of theological upheaval, his works helped forge a new theological tradition in Syriac. This groundbreaking collection of original essays refocuses attention on this fascinating Late Antique thinker and illustrates his importance for understanding Christianity in Late Antiquity. The essays highlight Narsai's contributions to exegesis, asceticism and moral formation, Jewish-Christian relations, liturgical theology, and place his work and thought within the cultural and intellectual world of two leading Christian centers in the Roman-Persian frontiers in the fifth century.
