Relics held by Rome for centuries returned to Constantinople

In a show of Catholic-Orthodox unity, the Holy See in Rome has returned relics of St. Gregory Nazianzen and St. John Chrysostom to the Constantinople See. The relics of Gregory Nazianzen (330-390) have been in Rome since the 8th century iconoclastic controversy, and the relics of John Chysostom (349-407) were brought to Rome following the 13th century sacking of Constantinople by Western European crusaders.
