I Changed My Mind

Let's say the Cardinal Dean says to you,  "Acceptasne electionem de te canonice factam in Summum Pontificem? (Do you accept your canonical election as Supreme Pontiff?)".  You can respond "non accepto" (I don't accept). Or you could say, "Sure. Why not?"If you are already a Bishop, you're in! The Cardinal  Dean then asks, "Quo nomine vis vocari? (By what name do you wish to be called?)". The Master of Pontifical Liturgical Ceremonies writes a document recording the acceptance and the new name of the pope. You go then to"The Room of Tears" just off the Sistine Chapel and choose a cassock, rochet, and red .mozzetta.The Senior Cardinal Deacon takes you to the balcony of the Basilica and announces:

Annuntio vobis gaudium magnum:
Habemus Papam!
Eminentissimum ac Reverendissimum Dominum,
Dominum [forename],
Sanctae Romanae Ecclesiae Cardinalem [surname],
qui sibi nomen imposuit [papal name].

 "I announce to you a great joy:
We have a Pope!
The Most Eminent and Most Reverend Lord,
Lord [forename],
Cardinal of the Holy Roman Church [surname],
who takes to himself the name [papal name]."

Then you say, "Urbi et Orbi ("to the City [Rome] and to the World")

Then it's party time, Jack!
