Troparion:
Light of Orthodoxy, pillar and teacher of the Church, adornment of monks and champion of theologians, O Gregory, wonderworker and boast of Thessalonika, preacher of grace, pray that our souls may be saved!
Kontakion:
Organ of wisdom, clear trumpet of theology, Gregory of divine speech, we praise thee. As thou dost stand before the Original Mind, direct our minds to Him, that we may cry: Rejoice, O Gregory, Herald of Grace!
