The Elevation of the Cross, celebrated on the fourteenth of September, commemorates the finding of Christ’s Cross by Saint Helen, the mother of the Emperor Constantine in the fourth century; and, after it was taken by the Persians, of its recovery by the Emperor Heraclius in the seventh century at which time it was “elevated” in the Church of the Resurrection in Jerusalem. From this latter event the “universal elevation” of the Cross was celebrated annually in all of the churches of the Christian Empire.
O Lord, save Thy people and bless Thine inheritance. Grant victories to the Orthodox Christians over their adversaries; and by the virtue of Thy Cross, preserve Thy habitation (Troparion).
As Thou was mercifully crucified for our sake, grant mercy to those who are called by Thy name; make all Orthodox Christians glad by Thy power, granting them victories over their adversaries, by bestowing on them the invincible trophy, Thy weapon of peace (Kontakion).
