Once the Cardinals have elected a new Pope, the most junior of the Cardinal Deacons calls the Secretary of the College of Cardinals and the Master of Pontifical Liturgical Celebrations into the Sistine Chapel.
The most senior Cardinal, speaking on behalf of all the electors, asks for the elected candidate’s consent with the following words: “Do you accept your canonical election as Supreme Pontiff?”
Upon receiving consent, he then asks: “What name do you wish to be called?”
The functions of a notary, with two Masters of Ceremonies acting as witnesses, are carried out by the Master of Pontifical Liturgical Celebrations, who drafts the document of acceptance and records the chosen name.
From this moment, the newly-elected Pope acquires full and supreme authority over the universal Church. The Conclave ends immediately at this point.
The Cardinal electors then pay homage and pledge obedience to the new Pope, and thanks are given to God.
The Cardinal Proto-Deacon then announces to the faithful the election and the name of the new Pontiff with the famous line: “Annuntio vobis gaudium magnum; Habemus Papam.”
Immediately afterward, the new Pope gives the Apostolic Blessing Urbi et Orbi from the Loggia of St. Peter’s Basilica.
The final step required is that, after the solemn inauguration ceremony of the Pontificate and within a suitable time, the new Pope formally takes possession of the Patriarchal Archbasilica of St. John Lateran. www.vaticannews.va
