From the Eastern Liturgy:
Liberator of captives, defender of the poor, physician of the sick, and champion of kings, O trophy-bearer, Great Martyr George, intercede with Christ God that our souls be saved.
Cultivated by God, you became manifest as an honorable tiller gathering for yourself the sheaves of virtue. For you sowed with tears but reaped with gladness; in the contest you competed with your blood and came away with Christ. By your intercessions, O Holy One, all are granted forgiveness of sins.
