Irmos: Thou art my strength, O Lord, Thou art my power; Thou art my God, Thou art my joy, Who, without leaving the bosom of the Father, hast visited our lowliness. Wherefore, with the Prophet Habbakuk I cry unto Thee: Glory to Thy power, O Thou Who lovest mankind!
Adorned with the beauties of thy struggles, invested with a robe empurpled with thy martyr’s blood, thou wast adorned with the diadem of victory. Wherefore, thou joinest chorus with the martyrs before the face of the Lord, O most blessed Theodore.
Theotokion: Thou art the boast of the faithful, O unwedded one; thou art the intercessor, thou art the refuge, the bulwark and haven of Christians; for thou bearest entreaties to thy Son, O most immaculate one, and savest from tribulations those who with faith and love glorify thee as the pure Theotokos.
Thy feet fettered with iron in prison, O invincible Callistus, thou didst pray that thou mightest walk the straight path without faltering; and, parted from thy body by the sword, thou wast straightway bound by the love of the Creator.
Having contended lawfully and been beheaded for Christ, the Head of all, the divine army, the regiment mustered by God, the forty-two athletes from many places and cities, have now shone forth.
