An antipope is a person who claims to be Bishop of Rome and leader of the Catholic Church in opposition to the legitimately elected pope. Between the 3rd and mid-15th centuries, antipopes were supported by factions within the Church itself and secular rulers.
Baldassarre Cossa was Pisan antipope John XXIII (1410–1415) during the Western Schism. The Catholic Church regards him as an antipope, as he opposed Pope Gregory XII whom the Catholic Church now recognizes as the rightful successor of Saint Peter. He was also an opponent of Antipope Benedict XIII, who was recognized by the French clergy and monarchy as the legitimate Pontiff.
The Council of Constance was an ecumenical council of the Catholic Church that was held from 1414 to 1418 in the Bishopric of Constance (Konstanz) in present-day Germany. The council ended the Western Schism by deposing or accepting the resignation of the remaining papal claimants and by electing Pope Martin V. It was the last papal election to take place outside of Italy.
The pope, also known as the supreme pontiff, Roman pontiff or sovereign pontiff, is the bishop of Rome, head of the worldwide Catholic Church, and has also served as the head of state or sovereign of the Papal States and later the Vatican City State since the eighth century. From a Catholic viewpoint, the primacy of the bishop of Rome is largely derived from his role as the apostolic successor to Saint Peter, to whom primacy was conferred by Jesus, who gave Peter the Keys of Heaven and the powers of "binding and loosing", naming him as the "rock" upon which the Church would be built. The current pope is Francis, who was elected on 13 March 2013.
Pope Gregory XII, born Angelo Corraro, Corario, or Correr, was head of the Catholic Church from 30 November 1406 to 4 July 1415. Reigning during the Western Schism, he was opposed by the Avignon claimant Benedict XIII and the Pisan claimants Alexander V and John XXIII. Gregory XII wanted to unify the Church and voluntarily resigned in 1415 to end the schism.
The Avignon Papacy was the period from 1309 to 1376 during which seven successive popes resided in Avignon rather than in Rome. The situation arose from the conflict between the papacy and the French crown, culminating in the death of Pope Boniface VIII after his arrest and maltreatment by Philip IV of France. Following the subsequent death of Pope Benedict XI, Philip forced a deadlocked conclave to elect the French Clement V as pope in 1305. Clement refused to move to Rome, and in 1309 he moved his court to the papal enclave at Avignon, where it remained for the next 67 years. This absence from Rome is sometimes referred to as the "Babylonian captivity of the Papacy".
A papal coronation is the formal ceremony of the placing of the papal tiara on a newly elected pope. The first recorded papal coronation was of Pope Nicholas I in 858. The most recent was the 1963 coronation of Paul VI, who soon afterwards abandoned the practice of wearing the tiara. To date, none of his successors have used the tiara, and their papal inauguration celebrations have included no coronation ceremony, although any future pope may elect to restore the use of the tiara at any point during his pontificate.
The Western Schism, also known as the Papal Schism, the Great Occidental Schism, or the Schism of 1378, was a split within the Catholic Church lasting from 1378 to 1417 in which bishops residing in Rome and Avignon both claimed to be the true pope, and were joined by a third line of Pisan claimants in 1409. The schism was driven by personalities and political allegiances, with the Avignon papacy being closely associated with the French monarchy.
A papal conclave is a gathering of the College of Cardinals convened to elect a bishop of Rome, also known as the pope. Catholics consider the pope to be the apostolic successor of Saint Peter and the earthly head of the Catholic Church.
A papal renunciation also called a papal abdication, occurs when the current pope of the Catholic Church voluntarily resigns his position. As a pope's time in office has conventionally lasted from his election until his death, a papal renunciation is an uncommon event. Before the 21st century, only five popes unambiguously resigned with historical certainty, all between the 10th and 15th centuries. Additionally, there are disputed claims of four popes having resigned, dating from the 3rd to the 11th centuries; a fifth disputed case may have involved an antipope.
Pedro Martínez de Luna y Pérez de Gotor, known as el Papa Luna in Spanish and Pope Luna in English, was an Aragonese nobleman who, as Benedict XIII, is considered an antipope by the Catholic Church.
Habemus papam or Papam habemus is the announcement traditionally given by the protodeacon of the College of Cardinals or by the senior cardinal deacon participating in the papal conclave, in Latin, upon the election of a new pope of the Roman Catholic Church.
Sedeprivationism is a doctrinal position within Traditionalist Catholicism which holds that the current occupant of the Holy See is a duly-elected pope, but lacks the authority and ability to teach or to govern unless he recants the changes brought by the Second Vatican Council. The doctrine asserts that since this council, occupants of the See of Peter are popes materialiter sed non formaliter, that is "materially but not formally". As such, sedeprivationists teach that Pope John XXIII, Pope Paul VI, Pope John Paul I, Pope John Paul II, Pope Benedict XVI, and Pope Francis have not attained fullness of the papacy.
According to Roman Catholicism, the history of the papacy, the office held by the pope as head of the Catholic Church, spans from the time of Peter to the present day.
The Catholic Church in Africa is part of the worldwide Catholic Church in full communion with the Holy See in Rome.
Conclavism is the practice that has existed since the second half of the 20th century which consists in the convening of a conclave to elect rival popes (antipopes) to the current pope of Rome. This method is used by some Catholics, often Sedevacantists, who do not accept the legitimacy of their present papacy. Those who hold the position that a conclave can be convened to elect a pope to rival the current pope of Rome are called Conclavists.
Most Holy Family Monastery is a sedevacantist organization, based in Fillmore, New York. It is headed by two siblings, Michael and Peter Dimond.
Peter of Candia, also known as Peter Phillarges, named as Alexander V, was an antipope elected by the Council of Pisa during the Western Schism (1378–1417). He reigned briefly from 26 June 1409, to his death in 1410, in opposition to the Roman pope Gregory XII and the Avignon antipope Benedict XIII. In the 20th century, the Catholic Church reinterpreted the Western Schism by recognising the Roman popes, as legitimate. Gregory XII's reign was extended to 1415, and Alexander V is now regarded as an antipope.
