Irmos: Madly did the Chaldæan tyrant heat the furnace sevenfold for the pious ones; but, beholding them saved by a higher Power, he cried out to the Creator and Deliverer: Ye children, bless; ye priests, hymn; ye people, exalt Him supremely for all ages!
The choir of athletes received thee as another of its number, shining with the beauties of martyrdom; the air was sanctified in thy return, O martyr, and multitudes of angels assembled; and the ground where thy body lieth is hallowed, O thrice-blessed Theodore of steadfast mind.
Being already heir of the Lord, led of thine own will to slaughter, O Callistus, thou didst not allow thyself to be bound with bonds when thy head was cut off. Wherefore, having ascended as one crowned, thou joinest chorus with the hosts on high for all ages.
Theotokion: O most pure Theotokos, cleanse thou the wounds of my soul and the stripes of my sins, washing them with springs which gush forth from the side of thine Offspring and purifying them with streams therefrom; for to thee do I cry, to thee do I flee, and thee, who art full of the grace of God, do I invoke.
Let Callistus be blessed, and let Theodore be praised, and the wondrous Basoës and the rest of the choir of the martyrs, joining chorus with the choirs of angels and chanting unceasingly: Ye children, bless; ye priests, hymn; ye people, exalt God supremely for all ages!
Cast into the river, the glorious martyrs were led, after the retribution of the sword, to the right calm haven which is rest in Christ; and having dried up the waters of deception with torrents of blood, they have taught all to chant: Ye children, bless; ye priests, hymn; ye people, exalt God supremely for all ages!
