"You both stand before the divine Throne..."

The Holy Glorious and All-Praised Leaders of the Apostles, Peter and Paul (source)

  
Peter, the leader of the glorious Apostles, the rock of faith, and Paul most sublime, the rhetor and light of the Holy Churches, you both stand before the divine Throne, entreating Christ on behalf of us.

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