Irmos: Once, in Babylon, the fiery furnace divided its activity at the command of God, consuming the Chaldæans, but bedewing the faithful, who chant: Bless the Lord, all ye works of the Lord!
Theotokion: O Virgin, we know thee to be another ark of the covenant and a house full of the glory of God; for the All-divine One chose thee before all generations and was pleased, as God, to make His abode within thee.
As a successor to the apostles in throne, grace, faith and purity, thou wast shown to be a healer of illnesses and passions and an expeller of evil spirits, O venerable one.
By abstinence thou didst vanquish the passions and the sowers thereof, O Gregory, and, having attained dispassion, thou didst chant to thy Master: Bless the Lord, all ye works of the Lord!
Anointed with noetic myrrh, thou hast poured forth myrrh, both tangible and noetic, from thy divinely inspired words and the shrine of thy relics, as a wonderworker.
