Venerable Paraskevi (Petka) of Serbia - Troparion & Kontakion
Troparion — Tone 2
You loved the solitary and hesychastic life, / and then, with diligence, you hastened after Christ, your Bridegroom, and took up His easy yoke in your youth. / Armed with the Sign of the Cross, / you contended courageously against noetic enemies; / through fasting, prayer, and by shedding tears, / you extinguished the embers of the passions, O glorious Paraskevḗ. / Now, standing in the heavenly Bridal Chamber of Christ, together with the wise virgins, / intercede for us who honor your holy memory.
Kontakion — Tone 6
Devoutly let us all praise the most honorable Paraskevḗ, / a holy intercessor for the afflicted; / for she left this perishable life behind and received eternal incorruption. / Therefore, she has been given the grace of working miracles, by the command of God.
