Troparion — Tone 8
O light of Orthodoxy, teacher of the Church, its confirmation, / O ideal of monks and invincible champion of theologians, / O wonder-working Gregory, glory of Thessalonica and preacher of grace, / always intercede before the Lord that our souls may be saved.
Kontakion — Tone 4
Now is the time for action! / Judgment Judgment is at the doors! / So let us rise and fast, / offering alms with tears of compunction and crying: / “Our sins are more in number than the sands of the sea; / but forgive us, O Master of All, / so that we may receive the incorruptible crowns.”
Kontakion — Tone 8
Holy and divine instrument of wisdom, / joyful trumpet of theology, / together we sing your praises, O God-inspired Gregory. / Since you now stand before the Original Mind, guide our minds to Him, O Father, / so that we may sing to you: “Rejoice, preacher of grace.”
