Saint Gregory the Illuminator or Saint Gregory the Enlightener (Armenian: Գրիգոր Լուսաւորիչ translit. Grigor Lusavorich, Greek: Γρηγόριος Φωστήρ or Φωτιστής, Gregorios Phoster or Photistes) (c. 257 – c. 331) is the patron saint and first official head of the Armenian Apostolic Church. He was a religious leader who is credited with converting Armenia from paganism to Christianity, Armenia thus being the first nation to adopt Christianity as its official religion in 301.

Gregory was the son of the Armenian Parthian noblesAnak and Okohe. His father Anak, who was a Prince said to be related to the Arsacid Kings of Armenia or was from the house of Suren-Pahlaw, one of the seven branches of the ruling Arsacid dynasty of Bactria. Anak was charged with assassinating Khosrov II, one of the kings of the Arsacid dynasty and was put to death. Gregory narrowly escaped execution with the help of Sopia and Yevtagh, his caretakers. He was taken to Caesarea in Cappadocia where Sopia and Yevtagh hoped to raise him. Gregory was given to the Christian Holy Father Phirmilianos (Euthalius) to be educated and was brought up as a devout Christian.
