  • The See of St. Peter, the Rock of the Church, the Source of Jurisdiction, and the Centre of Unity, by Thomas William Allies (London: Catholic Truth Society, 1896). Available at Internet Archive and Open Library.

On the Feast of Pope St. Gregory the Great in the Latin church (Extraordinary Form of the Roman rite) and in the Eastern Catholic churches; and at the beginning of the conclave to elect the successor of Pope Emeritus Benedict XVI. Thus we pray:

“O Lord, with suppliant humility, we entreat you, that in your boundless mercy, you would grant the most holy Roman Church a pontiff, who, by his zeal for us, may be pleasing to you, and by his good government may ever be honoured by your people for the glory of your name.” (From the Catholic News Agency)
