Irmos: O Lord Who by divine knowledge brought the ends of the earth into the light out of the night of ignorance, enlighten me with the dawning of Thy love for mankind.
Theotokion: Thou wast shown to be the east of the Sun of righteousness, O most immaculate one. Him do thou entreat, that He save those who glorify thee in purity.
Loving Christ our God most ardently, O martyr, thou didst suffer, and hast destroyed the feeble strength of the enemy.
Thou was shown to be the leader of divine recruits, O martyr Callistratus, and, rejoicing, hast enlisted in the armies of the angels.
Adorned with the glory of the splendor of martyrdom, O Gymnasius, rejoicing, thou hast now passed over to the splendors of the angels.
