The great ancient Latin hymn Vexilla Regis that exults in the Cross as the banner of Christ the King sung in the Church of the Holy Sepulchre by the Magnificat Custody Choir at the close of the prayer service conducted by the Holy Father Pope Francis and the Ecumenical Patriarch of Constantinople Bartholomew:

Pray the Joyful Mysteries of the Rosary on Monday for the See of Constantinople, the Sorrowful Mysteries of the Rosary on Tuesday for the See of Antioch, the Glorious Mysteries on Thursday for the See of Alexandria, and the Sorrowful Mysteries on Friday for the See of Carthage; for their liberty and their salvation and the restoration of their ancient position as pillars of the one, holy, catholic, and apostolic Church in communion with the See of Peter in Rome; for the conversion of the Jewish people and the conversion of the Muslim peoples.
