Gregory the Enlightener
Apostle
Commemorated September 30
Our father among the saints Gregory the Enlightener also Gregory the Illuminator (Armenian: Գրիգոր Լուսաւորիչ translit. Grigor Lusavorich , Greek: Γρηγόριος Φωστήρ or Φωτιστής , Gregorios Phoster or Photistes ), Equal of the Apostles and Enlightener of Armenia, was the religious leader credited with forging the Christian identity of Armenia by converting them from pagan beliefs. Armenia became the first country to establish itself as a Christian nation, an event traditionally dated to 301, now believed by most scholars to have occurred somewhat later, though before 314. This great missionary saint is commemorated on September 30 .
