Irmos: Thou art my strength, O Lord, Thou art my power; Thou art my God, Thou art my joy, Who, without leaving the bosom of the Father, hast visited our lowliness. Wherefore, with the Prophet Habbakuk I cry unto Thee: Glory to Thy power, O Thou Who lovest mankind!
Having ploughed the good earth, O divinely wise father, and sown the seed of the Word, thou dost even now evangelically increase thy yield an hundredfold, O Gregory, by thy teachings bringing to God those who chant: Glory to Thy power, O Thou Who lovest mankind!
Theotokion: From of old the ark prefigured thee, O all-immaculate one, who received within thy womb the divinely written Law, ineffably conceiving the life-creating Word, Who doth richly nourish the souls of those who cry: Glory to Thy power, O Thou Who lovest mankind!
Shining forth like lightning, O father, thy life hath dispelled the deception of the demons; for their darkness could not withstand the light of thy virtues. Wherefore, the minister of spiritually pernicious deception, moved like the stone he beheld, was enlightened.
Thou wast vouchsafed to behold the darkness of most divine Light, O father, and, having received the divinely written law like Moses, thou didst attain the precision of theology. Hence, thou hast been shown to be a law-giver of the Church of Christ, O divinely wise Gregory.
Having turned away from the foolish talk of the rhetors and being enlightened by the word of grace, O father, thou didst truly receive the apostles’ power over the demons, for the prince of darkness fled before thy brilliant splendor.
