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.
Having taken up the angelic life on earth, O venerable and divinely wise Theodore, by fasting and all manner of affliction thou didst kill the uprisings of the passions.
Theotokion: Thou alone gavest birth to the Creator and Lord of all, the hypostatic Life, O all-pure one; and loving Him, the multitude of venerable fathers lived in holiness.
Ever contemplating the hour of judgment, rising early thou didst drive from thy soul the sleep of despondency, adorned with divine love.
Loving the mansions on high as a true monk, thou didst raise up on the earth houses for monastics; and having been established therein by thee, they honor thee, O venerable one.
