About the Commemoration

Gregory, who was born about 257, is called “the Illuminator” or “the Enlightener” because he brought the light of the gospel to the people of Armenia. Extravagant legend clouds the details of Gregory’s life. He is said to have been the son of a Parthian who assassinated the Persian King Khrosrov I. The infant Gregory was taken for safety to Caesarea in Cappadocia, where he was baptized and brought up. He married and had two sons, returned to Armenia about 280, and converted King Tiridates (Tradt) III. Gregory, in about 300, was consecrated a bishop at Caesarea and spent the rest of his life preaching and organizing the church in Armenia. Shortly before his death, Gregory, having appointed his son Aristages to be chief bishop (katholikos) of the Armenian Church in his place, withdrew into solitude.

Armenia was the first country to become officially a Christian nation and thus set a precedent for the adoption of Christianity by the Roman Emperor Constantine.

Gregory is on the calendar in the Book of Common Prayer because the Anglican Communion has enjoyed a warm friendship with the Armenian Church for many years. He is not included in the General Roman Calendar.

From The Life of St. Gregory the Illuminator by Agathangelos

Throughout the whole land of Armenia, from end to end, Gregory extended the labor of preaching the Gospel.

All the time of his life, summer and winter, day and night, intrepidly and without hesitation in his course of preaching the good word, before the king and princes of all the heathen without let or hindrance he bore the name of Jesus the Savior of all, and he furnished every soul with divine vesture and spiritual arms.

He afforded salvation to many prisoners and captives and people oppressed by tyrants, freeing them by the awesome power of Christ’s glory….And to many in mourning or disheartened, through his consoling teaching he gave the expectation of hope in the appearance of the glory of our great God and Savior of all, Jesus Christ. And he turned everyone to the state of true piety….He himself at frequent intervals went out to deserted mountains where he made himself an example. He took various of the pupils from each monastery and went to live in the mountains in solitude; in grottoes and caverns they made herbs their daily food.
