Irmos: Once, in Babylon, the fire stood in awe of the condescension of God; wherefore, the youths, dancing with joyous step in the furnace, as in a meadow, chanted: Blessed art Thou, O God of our fathers!
The boast of the fathers and pride of the holy teachers, the luminary of the Church and immovable pillar of piety hast thou been shown to be, O Gregory, who criest out: Blessed is the God of our fathers!
Theotokion: Now are all things full of divine light through thee, O all-pure one; for thou art shown to be the door through which God hath communed with the world, enlightening those who cry with faith: Blessed is the God of our fathers!
Shining forth in miracles, thou didst enlighten the whole world, O divinely wise Gregory; wherefore, having assembled together, we bless thee, nurtured by thy words and chanting: Blessed is the God of our fathers!
O divinely wise one, thou hast poured forth healing upon all the infirm; for most abundant and wonder-working grace was poured into thy mouth, whereby thou didst cry: Blessed is the God of our fathers!
