Ten years after the death of this noble apostle of Armenia, the valiant defender of that divine faith also ended his useful career (342), after seeing the prosperous condition of the Church, which they loved and for which they toiled. Both were succeeded by their sons. The power of Armenia, however, was not equal to the conflicting forces on either side, though the descendants of Tiridates held the scepter of Armenia nearly a century longer, it was in a very enervated state. Nevertheless the Church of Christ made a decided advance within this period. The Armenian alphabetic characters[41] were recovered and completed by the distinguished scholar and prelate Mesrob, who, with St. Isaac, the patriarch, or bishop, translated the Scriptures into the Armenian language, the Old Testament from the Septuagint version and the New Testament from the original Greek.[42] After the conversion of the Armenians to Christianity not a few of the youths of Armenia flocked into the schools of Athens, Alexandria, and Constantinople, to sate their avidity for learning, who, afterwards, rendered great service to the nation, both by their writings, and many valuable translations from the Greek. Some of these originals have been lost and the world now has them in Armenian only. The rise of the Sassanian dynasty in Persia was a source of more or less perpetual misery and bloodshed in Armenia. The Persians had two reasons for their cruel attitude toward Armenia. The first was the continued existence of the Arsacide reign in Armenia; the second was Armenia’s conversion to Christianity, while Zoroastrianism was revived in Persia by the Sassanian Kings. Christianity was the permanent occasion for which Armenia has suffered and is still suffering indescribable miseries and innumerable cruelties. The Persians imagined that as long as the Armenians were Christians they were in alliance with the Greeks, while in reality the Greeks were no more in sympathy with them than the Persians were.
