When Heraclius was crowned Emperor on October 5, 610, after the overthrow of the unworthy Phocas, the provinces on all sides were overrun by the Persians, Avars, and Slavs. He started on a series of internal reforms, such as canceling the dole of grain, which enabled a great many able-bodied loafers in Constantinople to spend their time attending the circus and games instead of doing something useful, and in trying to improve the finances of the government. He embarked on a series of campaigns in due course of time to re-establish Byzantine rule in the neighboring parts of the Empire. The Persians had for some years been harassing Syria and Asia Minor, and in 613 they attacked the city of Damascus. The next year they took Jerusalem, and left a garrison in charge of the city. The population revolted as soon as the main body of the invading army left, and slaughtered the garrison. This brought back the conquerors, who are said to have killed 90,000 of the inhabitants, sparing only the Jews who aided them in the conquest. They took the Patriarch Zacharias and the case containing the relics of the cross back to Persia with them.
This event was regarded by all the Christians as the greatest possible disaster, since they regarded the sacred relics as the palladium of the city. Added to this was the insolence of Chosroes, King of the Persians, who taunted the Christians with their religion and their Lord, who so obviously had failed to deliver them. For the next eight years Heraclius was busy with the Avars, and was not able to go out against the Persians until 622. He waged six campaigns between 622 and 627, and finally defeated Chosroes and his generals decisively, but at great cost. The Empire was in great danger: in 626 the Persians were in Asia Minor right across the Bosporus from the City, while their barbarian allies were encamped on the north in Thrace. But Heraclius managed to fight them all off, and restore some control.
He brought back to Jerusalem the Patriarch and the relics of the cross, which had not been molested. The populace demanded to see and venerate the relics, and accordingly they were solemnly elevated for all to see and reverence. The Emperor took a part of the sacred wood back to Constantinople with him. From the time of the finding of the cross by the Empress Helena, small bits of the wood were sent all over the world as most sacred relics, and the part which remained, although large, was still portable.
The hard-won peace of 626 left both the Persian anti Byzantine empires exhausted. At this very time a new danger appeared on the horizon: both Chosroes and Heraclius received letters from the Arab Mohammed, who invited them to adopt Islam, his newly founded faith. They both declined, but their contacts with the Moslems were to be many and difficult. In 629 Arab attacks on the empires began, and in 635 Damascus was taken, and Jerusalem in 637. Heraclius went back to Jerusalem and removed the sacred relics to Constantinople for safe keeping, but the Patriarch remained behind to greet the new rulers.
The ceremony of Elevation as performed in Church is actually a patriotic one, with prayers for the Rulers and their people, for Church and State, and for their establishment and preservation. The key to the observance is to be found in the Hymn for the Feast, the Troparion, which runs as follows:
“O Lord, save Your people, and bless Your inheritance.
Grant victories to the Orthodox Christians over their adversaries
and by virtue of Your Cross, preserve Your habitation.”
To the Byzantines, their Empire was the civilized world, the Oikoumene, the habitation of law and order; outside the pale were the barbarians, the people who spoke some other language that no one could understand, and whose ways were violent and strange. The Christian religion was a part of this, the vehicle of salvation and civilization. This is the heritage that was transmitted down through the ages by the Byzantine Empire, the struggle for civilization against the power of the destroyers. When we celebrate the feast today, we should have this in mind; it is apt that the Feast of the Cross is always a Fast. This paradox is striking, but accentuates the understanding our ancestors had that victory comes hard, and that nothing good is achieved without sacrifice.
