We have found your sacred shrine to be a clinic of the soul, O holy one, and all we faithful now accord honor to you with our voices strong, devout Martyr Paraskevi extolled by all.
The voice of the Bridegroom called you as a bride, and gave you an incorruptible crown, O godly-minded and all glorious Paraskevi; and He enrolled you, as one worthy, together with the august martyrs and prizewinners. As you rejoice with them, remember us who observe your holy feast and who assemble in your church. For as we stand in it now, we soulfully offer up hymns to you, devout Martyr Paraskevi extolled by all.
Prosomoia of the Praises - 1st Tone. For the celestial orders.
You dashed the might of the godless impious kings to the ground, * and unto God, O Virgin, * you directed your footsteps. * Therefore you were not frightened by the lead * hammers pounding you, nor the fire, * nor by the scraping of your body, nor by the heat * of the cauldron, nor the death by sword.
Firstly you wore out your body with your ascetic feats, * fair Virgin, then you hardened * your resolve in the contest. * Thus, O holy glorious Martyr of Christ, * you became like a holy sword * wrought in the heavens, like gold smelted and refined * by the tortures you endured for God.
