Irmos: O Lord, Bestower of light and Creator of the ages: guide us in the light of Thy commandments, for we know none other God than Thee.
The enemy is put to shame, and the heresiarchs become insane with rage, beholding thy shrine venerated with faith by the emperor and all thy flock, O divinely wise one.
Theotokion: Made comely by the descent of the all-holy Spirit, thou gavest suck unto God at thy breasts and heldest in thine arms Him Who holdeth all creation in His hand.
Like a dreadful scourge doth thy sacred shrine drive out the evil spirits of the demons, and it receiveth from God the victory of divine glory over them, O Nicephorus.
The crucible of conscience heated by the fire of the Spirit showed thee to be as lustrous as gold through thy faith, exposing the vileness of the heretics.
