The next pope will be elected at a papal conclave, a meeting of the College of Cardinals. The authority of the pope as leader of the Catholic Church is based on the fact that he is the Bishop of Rome and successor to Peter. The Diocese of Rome includes the Vatican State and the city of Rome. Since 1059 the election of the pope is reserved to the pastors of churches in either the Diocese of Rome or one of the seven adjacent (or suburbicarian) dioceses. When cardinals receive their red hats, they also become titular pastors (an appointment without formal authority) of a parish in the Diocese of Rome or in one of the suburbicarian dioceses adjacent to Rome. It is as titular pastors of these churches that they have the authority to elect the new pope.
After the death of a pope, there is a 15 day period to celebrate the funeral Mass and burial of the pope, as well as a period of mourning.
The death of a pope has been the usual time for the election of a new pontiff. The Cardinal Camerlengo, or Chamberlain, declares the death of the pope in the presence of the Master of Papal Liturgical Celebrations, the Cleric Prelates, and the Chancellor of the Apostolic Camera. The Cardinal Camerlengo takes possession of the Ring of the Fisherman, the symbol of papal authority. Then the ring and the papal seal are destroyed before the College of Cardinals.
There will be 135 eligible cardinals in the 2025 conclave.
On the morning designated for the beginning of the conclave, the cardinal electors will celebrate the Eucharist in St. Peter’s Basilica. In the afternoon they will gather and process from the Pauline Chapel of the Palace of the Vatican to the Sistine Chapel, while singing Veni Creator Spiritus.
Upon arriving in the Sistine Chapel, the cardinals will take an oath to defend the liberty of the Holy See, to keep all the proceedings secret, and to ignore any instructions they might have received from secular authorities on how to vote.
The cardinals will have to give up their cell phones and any other electronic devices.
On the first afternoon of the conclave, the first ballot may be held. There can be as many as four ballots on each day following. Before voting on each ballot, the cardinals take an oath to follow the rules of the conclave.
If there is no one elected pope at the end of three days of balloting, the cardinals have a day of reflection and prayer. If there are seven more ballots without result, the process may be suspended once again.
The voting continues until a two-thirds majority is reached for a candidate. If there are more than 33 votes without an election, the pope may be chosen by a simple majority.
If a new pope is not elected in a ballot, the ballots are burned with chemicals that cause the smoke from the chimney to come out as black. Upon the election of the pope, the smoke from the ballots will be white, and bells will ring to announce a successful election.
When a cardinal has been elected, he is asked in Latin by the Cardinal Dean “Acceptasne electionem de te canonice factam in Summum Pontificem?” (“Do you accept your canonical election as Supreme Pontiff?”) The cardinal who is elected has the choice of saying “non accepto” (“I don’t accept”). If a cardinal does not intend to accept the papacy, he will explicitly state this before he receives a sufficient number of votes to become pope-elect. Cardinal Giovanni Colombo declared his intention not to accept the papacy in the conclave of 1978.
After the newly-elected pope accepts his election, the Cardinal Dean asks him about his papal name, saying in Latin: “Quo nomine vis vocari?” (“By what name do you wish to be called?”) After the papal name is chosen, the officials are readmitted to the conclave, and the Master of Pontifical Liturgical Ceremonies writes a document recording the acceptance and the new name of the pope.
In theory, any baptized Catholic male can be elected pope. Current law states that he must be an ordained bishop. Only cardinals have been elected since the 15th century.
Thirty-four popes have been members of religious orders. They include 17 Benedictines, six Augustinians, four Dominicans, four Franciscans, two Cistercians, and one Jesuit: Pope Francis.
Choosing a name is a personal decision. John XXIII chose his father’s name. John Paul I was the first to choose two names to honor his immediate predecessors, John XXIII and Paul VI. John Paul II chose his name to show his esteem for John Paul I. Benedict XVI took the name to honor Benedict XV (pope from 1914 to 1922) and St. Benedict of Nursia, who founded and inspired the Benedictine monastic tradition in the Western Church. Pope Francis chose his name after St. Francis of Assisi, who is known for his care for the poor.
During the transition period, certain limited powers pass to the College of Cardinals. Vatican offices suspend activities until a new pope is elected. The Particular Congregation deals with the everyday matters of the Church.
