As Gregory was consecrated by the bishop of Caesarea, he also accepted the Byzantine Rite. However, the Armenian Church, due to the influence of the Church in Edessa, the large presence of Syriacs in Armenia, as well as the number of Syriac priests that arrived in Armenia with Gregory, also cultivated the West Syriac Rite (Antiochian Rite). Since Armenians at the time didn't have an alphabet, its clergy learned Greek and Syriac. From this synthesis, the new Armenian Rite came about, which had similarities both with the Byzantine and the Antiochian Syriac rite.
