Irmos: Thou hast come, O my Lord, as a light into the world: a holy light turning from the darkness of ignorance those who hymn Thee with faith.
With thy words of truth thou didst break the chains of the rhetors, O Porphyrius, establishing the dominion of faith in all ways.
Theotokion: Strengthened by thee, O all-pure one, with the power of the Spirit we vanquish the adverse foes of the truth of Christ.
Having drawn forth the Comforter on earth, O venerable one, thou didst pour forth bountiful rivers of the teachings of piety, O Porphyrius.
Having dried up the torrents of ungodliness with the fire of thy words, O Porphyrius, thou didst enlighten men with the proclamation of piety.
