Onesiphorus and Porphyrius of Ephesus
During the persecution of Diocletian and Maximian, about the year 290, Saints Onesiphorus and Porphyrius were betrayed as Christians to the persecutors. After many torments through which they stood fast in confessing their faith, they were bound by the feet to wild horses and dragged to death.
Apolytikion of Martyrs Onesiphorus & Porphyrius in the Fourth Tone
Thy Martyrs, O Lord, in their courageous contest for Thee received as the prize the crowns of incorruption and life from Thee, our immortal God. For since they possessed Thy strength, they cast down the tyrants and wholly destroyed the demons' strengthless presumption. O Christ God, by their prayers, save our souls, since Thou art merciful.
Kontakion of Martyrs Onesiphorus & Porphyrius in the Second Tone
The martyric pair contested with great steadfastness and dashed to the earth the boasting of the enemy and were made to shine with the grace of the uncreated Trinity, and now with the angelic Hosts the glorious Martyrs pray to God for us.
