From Vatican Radio:
Pope Francis has declared Armenian poet and monk, Saint Gregory of Narek, a Doctor of the Universal Church. Meeting with Cardinal Angelo Amato, Prefect of the Congregation for the Cause of Saints on Saturday ahead of his departure for Aricca on Lenten retreat, the Pope confirmed the proposal put forward by the Plenary Session of the Congregation to confer the title of Doctor of the Universal Church on the 10th century saint.
St. Gregory of Narek is widely revered as one of the greatest figures of medieval Armenian religious thought and literature. Born in the city of Narek in about 950 A.D., St. Gregory came from a line of scholars and churchmen.
St. Gregory received his education under the guidance of his father, Bishop Khosrov, author of the earliest commentary on the Divine Liturgy, and from Anania Vartabed, abbess of Narek Monastery. He and his two brothers entered monastic life at an early age, and St. Gregory soon began to excel in music, astronomy, geometry, mathematics, literature, and theology.
He became a priest at the age of 25 and dedicated himself to God. He lived most of his life in the monastery of Narek, where he taught at the monastic school. St. Gregory began his writings with a commentary on the “Song of Songs,” which was commissioned by an Armenian prince. Despite his reservations that he was too young for the task, the commentary became famous for its clarity of thought and language and its excellence of theological presentation.
He also wrote a number of famous letters, sharagans, treasures, odes, melodies, and discourses. Many of his prayers are included in the Divine Liturgy celebrated each Sunday in Armenian Churches around the world.
