The Holy Martyrs Porphyrius and Onesiphorus of Ephesus suffered during the persecution against Christians under the emperor Diocletian (284-305). They beat them and burned them. After this, they tied the saints to wild horses, which dragged them over the stones, after which the Martyrs Onesiphorus and Porphyrius died. Believers gathered the relics of the saints and reverently buried them.
Troparion - Tone 4
Your holy martyrs, Onesiphorus and Porphyrius, O Lord,
through their sufferings have received incorruptible crowns from You, our God.
For having Your strength, they laid low their adversaries,
and shattered the powerless boldness of demons.
Through their intercessions, save our souls!
Kontakion - Tone 2
The pair of glorious martyrs, Onesiphorus and Porphyrius,
endured their suffering with strength,
dashing down to the earth the arrogance of the enemy,
and shining with the grace of the uncreated Trinity;
together with the angels, they unceasingly pray for us all.
