Troparion — Tone 4
By sharing in the ways of the Apostles, / you became a successor to their throne. / Through the practice of virtue, you found the way to divine contemplation, / O inspired one of God; / by teaching the word of truth without error, / you defended the Faith, even to the shedding of your blood. / Hieromartyr Gregory entreat Christ God to save our souls.
Kontakion — Tone 2
Today, let us the faithful, praise with songs and hymns / the admirable hierarch Gregory as an initiate in the sacred mysteries. / He was a contender for the truth, a vigilant pastor and teacher, / a light for the whole world, / interceding with Christ that our souls may be saved!
