"The citizens of the Jerusalem on high..."

Sts. Peter and Paul the Apostles (source)

  
The citizens of the Jerusalem on high, the rock of faith, the orators of the Church of Christ, the dyad of the Trinity, those who netted the world, today depart the things on earth, and proceed to God through their struggle, and they intercede to Him with boldness that our souls be saved.
-Idiomelon of the Litia in the Third Tone, by St. John of Damascus

Through the prayers of our Holy Fathers, Lord Jesus Christ our God, have mercy on us and save us! Amen!
