Great Martyr Nicholas of Sofia (Bulgaria) - Troparion & Kontakion
Troparion — Tone 3
You were enriched by the dawn of the Spirit, O glorious one, / and from Whom you received boldness, you brought forth the Trinity one in essence at the Lord's judgment; / therefore, you were pelted with stones, but were not defeated by this. / You were burnt in the fire, and denounced the delusion of the godless. / O much-suffering Saint Nicholas, entreat Christ God to grant our souls great mercy.
Kontakion — Tone 2
Let us praise the godly Nicholas in songs, / a true champion of piety, and invincible helper in troubles; / for in his last year he appeared as a most luminous star, / enlightening the hearts of the faithful; / and now he stands with the Angels before the Holy Trinity, / praying unceasingly for all of us.
