Tiridates found favor with the Roman Emperor Diocletian, who, with a great force, sent him to Armenia to retake his father’s throne from the Persians. He was welcomed by his people, who joined his army and drove out of the country their common enemy (A.D. 286). It appears that Gregory had sought Tiridates and found him in Rome and entered his services, his sole “purpose being to win over to eternal life, through the gospel of Christ, the son of him who had been slain by his father, and thus to make amends for his father’s crime.” Though Gregory suffered many a torture and torment and a long period of imprisonment, yet this noble Christian hero and apostle was determined “to win (the king) over to eternal life, through the gospel of Christ.” The king, finally, was converted and baptized by St. Gregory. Tiridates himself became a worthy champion of the truth, and the first honored king who proclaimed throughout his dominions that henceforth the religion of Christ is the religion of Armenia. The Armenians were nationally converted to Christianity, from the king down to the servant; we must not forget, however, that there were some especially among the nobility, who with a heathenish tenacity held on to the Zoroastrian faith, but this was for mercenary purposes rather than a real appreciation of Zoroastrianism. For Christianity had made a great advance in the country. Moreover, the apostle of Armenia, by his evangelistic spirit and labors, had laid a firm foundation for the religion of Christ in the land of Ararat (A.D. 289). He was, by the request of the king, sent to Cæsarea, Cappadocia, to be ordained bishop over Armenia (A.D. 302).[40] The temples of the idols in every important city and town were pulled down and Christian churches in their stead were built. The most splendid of all these churches was Etchmiadsin, “the descent of the only begotten,” which was afterwards clustered about with other buildings and became a monastery and to this day the seat of St. Gregory’s successors to his prelatic chair. In those days, and during a century afterwards, Christian training was carried on by the catechisers, for very few had access to the Syriac or Greek literature, and the Armenian literature also was written in either of these characters; the characters of the Armenian alphabet were not yet wholly discovered or completed. So the reader will bear in mind that the advantages of imparting or disseminating a thorough Christian knowledge, if not lacking wholly, were very inadequate. After a long and useful life St. Gregory entered into the joy of the Lord and Master (A.D. 332).
