Irmos: Once, in Babylon, the youths who had come forth from Judæa trod down the flame of the furnace with their faith in the Trinity, chanting: O God of our fathers, blessed art Thou!
Those who would deprive Christ of His two activities and wills deprived thee of thy see, O father, giving over to remote exile thee who criest: O God of our fathers, blessed art Thou!
Theotokion: He Who was ineffably born of thee in two wills and two activities, O all-immaculate one, saveth those who believe thus in Him and cry out: O God of our fathers, blessed art Thou!
Passing through long incarceration as a preserver of the unadulterated Faith, thou didst diminish the darkness of heresy and didst illumine the faithful to chant: O God of our fathers, blessed art Thou!
Trusting like a lion in thy strength, O father, thou didst boldly lay hold of the iniquitous Theodore, Cyrus, Sergius and Pyrrhus, separating them from the holy Churches of God, which are of like mind.
