Canon of the Holy Hierarch, in Tone II—

Irmos: Come, ye people, let us chant a hymn to Christ God, Who divided the sea and guided the people whom He had led forth from the bondage of Egypt, for He hath been glorified.

Theotokion: With hymns we glorify her who gave birth to God: the pure treasure of virginity, the deliverance of the human race and the joy of the angels.

O Savior Christ, never-waning Light of the world, send thou Thy noetic light to illumine my mind, that I may hymn the divine Gregory, the primate of Rome.

That He Who foreseeth all things might show thy virtue to the world, O most wise one, He set thee upon the visible summit of the hierarchy.

Finding thee to be an honored and most pure dwelling-place, O divinely wise and holy Gregory, the all-holy Trinity dwelt within thee and filled thee with divine gifts.
