O Gregory the Wonderworker, light of Orthodoxy, support and teacher of the Church, glory of monks and invincible protector of theologians, pride of Thessalonica and preacher of grace, pray without ceasing for the salvation of our souls.

Holy divine instrument of wisdom, joyful trumpet of theology, with one accord we sing thy praises, O Gregory inspired by God. But since thou standest now, in mind and spirit before the Original Mind, guide our minds to Him, O father that we may cry to thee: Hail preacher of Grace.
