Zoroastrianism in Armenia in the context of "Gregory the Illuminator"

Gregory the Illuminator (c. 257 – c. 331) was the founder and first official head of the Armenian Apostolic Church. He converted Armenia from Zoroastrianism to Christianity in the early fourth century (traditionally dated to 301), making Armenia the first state to adopt Christianity as its official religion. He is venerated as a saint in the Armenian Apostolic Church and in some other churches.

Gregory is said to have been the son of a Parthian nobleman, Anak, who assassinated the Arsacid king of Armenia Khosrov II. The young Gregory was saved from the extermination of Anak's family and was raised as a Christian in Caesarea of Cappadocia, then part of the Roman Empire. Gregory returned to Armenia as an adult and entered the service of King Tiridates III, who had Gregory tortured after he refused to make a sacrifice to a pagan goddess. After discovering Gregory's true identity, Tiridates had him thrown into a deep pit well called Khor Virap for 14 years. Gregory was miraculously saved from death and released after many years with the help of Tiridates' sister Khosrovidukht. Gregory then converted the King to Christianity, and Armenia then became the first country to adopt Christianity as a state religion in 301 AD. Gregory, the Illuminator, then healed King Tiridates, who the hagiographical sources say had been driven mad by his sins, and preached Christianity in Armenia. He was consecrated bishop of Armenia at Caesarea, baptized King Tiridates and the Armenian people, and traveled throughout Armenia, destroying pagan temples and building churches in their place.
