Irmos: Once, in Babylon, the youths who had come forth from Judæa trod down the flame of the furnace with their faith in the Trinity, chanting: O God of our fathers, blessed art Thou!
Theotokion: O divinely joyous one, entreat Him Who was incarnate of thee in manner past understanding and recounting, that we be saved who honor thee with love and cry out together: O God of our fathers, blessed art Thou!
Made lustrous as gold by the fire of torments, thou wast shown to be a symbol of the sufferings of Christ, O glorious one, and hast now been laid up in the treasury of God, crying: O God of our fathers, blessed art Thou!
Strengthened by sufferings, thou didst show thyself to be a heaven-forged sword, O Callistratus, cutting down hordes of invisible demons and crying out: O God of our fathers, blessed art Thou!
Thou wast revealed as strong against impiety with the might of the Trinity, O Callistratus; and, illumined with the effulgence thereof, thou now criest out: O God of our fathers, blessed art Thou!
Loving Christ with steadfast mind, O divinely inspired martyr Gymnasius, thou wast slain with all thy fellow zealots, chanting in thanksgiving: O God of our fathers, blessed art Thou!
