Armenian Apostolic Church marks on March 28 the commemoration of St. Gregory the Illuminator’s torments and commitment to the pit. This feast is the first one among the three commemoration days dedicated to the memory of St. Gregory the Illuminator, the first Catholicos of All Armenians. According to the Armenian Church Calendar, it is celebrated on the eve of the Fifth Sunday during the period of Great Lent. The feast is dedicated to the torments which St. Gregory suffered during his imprisonment.

In 301 A.D., after spending 13 years in the pit, St. Gregory the Illuminator is freed from the dungeon and emerges to spread the Light of Christ in Armenia. He thus becomes the first pontiff of the Armenian Church, baptizes the royal family, and evangelizes the whole of the Armenian Nation. Armenia becomes the first nation in the world to officially proclaim Christianity as her state religion.

St. Gregory the Illuminator is recognized by all of Christendom as a Saint, and he is commemorated in all traditional Christian Churches.
