Death and Election
Under present canon law, on the death of the Pope the government of the Catholic Church passes to the Chamberlain of the Holy Roman Church, a Cardinal of the Holy Roman Church appointed by the Pope during his lifetime; however, canon law specifically forbids the Cardinal Chamberlain from introducing any innovation in the government of the Church during the vacancy of the Holy See (sede vacante).
Theoretically, the Pope's death is officially determined by the Cardinal Chamberlain by gently tapping the late Pope's head thrice with a golden hammer and calling his name (it is not clear when this ceremony ceased to be observed, as it does not appear to have been practised in the XX Century at all). The Cardinal Chamberlain then removes the Fisherman's Ring from the Pope's right hand and smashes it (theoretically with the same hammer used to determine the Pope's death), and the body then lay in state for a number of days before being interred in the crypt of a leading church or cathedral; the Popes of the XX Century have all been interred in St. Peter's Basilica, but it is expected that the reigning Pope, Ioannes Paulus PP. II, will be interred in his native Poland. A nine-day period of mourning (novem dialis) follows after the interment of the late Pope.
The Pope was originally chosen by those senior clergymen resident in and near Rome. In 1059, the electorate was restricted to the Cardinals of the Holy Roman Church, and the individual votes of all Cardinal Electors were made equal in 1179. The Pope is usually a member of the College of Cardinals, but any male Catholic (including a layman) may be elected; Urbanus PP. VI was the last Pope who was not already a cardinal at the time of his election. Canon law requires that if a layman or non-bishop is elected, he receives episcopal consecration from the Dean of the College of Cardinals before assuming the Pontificate. Under present canon law, the Pope is elected by the cardinal electors, viz., those cardinals who are under the age of 80.
The Second Council of Lyons was convened on May 7, 1274, to regulate the election of the Pope. This Council decreed that the cardinal electors must meet within ten days of the Pope's death, and that they must remain in seclusion until a Pope has been elected; this was prompted by the three-year Sede Vacante following the death of Clemens PP. IV in 1268. By the mid-XVI Century, the electoral process had more or less evolved into its present form, allowing for alteration in the time between the death of the Pope and the meeting of the cardinal electors.
Traditionally the vote was conducted by acclamation, by selection by committee, or by plenary vote. Acclamation was the simplest procedure, consisting entirely of a voice vote, and was last used in 1621. The reigning Pope, Ioannes Paulus PP. II, has abolished vote by acclamation and by selection by committee, and henceforth all Popes will be elected by full vote of the Sacred College of Cardinals by ballot.
The election of the Pope almost always takes place in the Sistine Chapel, in a meeting called a "conclave" (so called because after twenty days after the Pope's death, the present cardinal electors are theoretically locked in, cum clavi, until they elect a new Pope). Three cardinals are chosen by lot to collect the votes of absent cardinal electors (by reason of illness), three are chosen by lot to count the votes, and three are chosen by lot to review the count of the votes. The ballots are distributed and each cardinal elector writes the name of his choice on it and pledges aloud that he is voting for "one whom under God I think ought to be elected" before depositing his vote. Balloting continues until a Pope is elected by two-third majority (since the promulgation of Universi Dominici Gregis in 1996 the rules allow for a simple majority after a deadlock of twelve days).
One of the most famous parts of the conclave is the means by which the results of a ballot are announced to the world. Once the ballots are counted, they are burned, and the smoke indicates the results: black smoke (sfumata), created using straw with the ballots, announces that the vote was not decisive, and white smoke announces the election of a new Pope. The Dean of the College of Cardinals asks the Pope-elect to confirm his acceptance, and then announces the name he has chosen for himself (starting in 535, the Pope has customarily chosen a new name for himself during his Pontificate). The senior cardinal deacon then announces from a balcony over St. Peter's Square the following proclamation: Annuntio vobis gaudium magnum! Habemus Papam! ("I announce to you a great joy! We have a Pope!")
Until 1978, the Pope's election was followed in a few days by a procession in great pomp and circumstance from the Sistine Chapel to St. Peter's Basilica, with the newly-elected Pope borne in the sedia gestatoria. There the Pope was crowned with the triregnum and he gave his first blessing as Pope, the famous Urbi et Orbi ("to the City [Rome] and to the World"). Another famed part of the coronation was the lighting of a torch which would flare brightly and promptly extinguish, with the admonition Sic transit gloria mundi ("Thus fades worldly glory").
As has been hitherto noted, the Latin term Sede Vacante ("vacant seat") refers to a Papal interregnum, or the period between the death of the Pope and the election of his successor. From this term is derived the name Sedevacantist, which designates a category of dissident, schismatic Catholics who maintain that there is no canonically and legitimately elected Pope, and that there is therefore a Sede Vacante; one of the most common reasons for holding this belief is the idea that the reforms of the Second Vatican Council and especially the replacement of the Tridentine Mass with the Novus Ordo Missae are heretical, and that, per the dogma of Papal infallibility (see above), it is impossible for a valid Pope to have done these things.
Objections to the Papacy
The Pope's position as Supreme Pontiff of the Universal Church is dogmatic and therefore not open to debate or dispute within the Catholic Church; the First Vatican Council anathematised all who dispute the Pope's primacy of honour and of jurisdiction (it is lawful to discuss the precise nature of that primacy, provided that such discussion does not violate the terms of the Council's Dogmatic Constitution). However, the Pope's authority is not undisputed outside the Catholic Church; these objections differ from denomination to denomination, but can roughly be outlined as (1.) objections to the extent of the primacy of the Pope; and (2.) objections to the institution of the Papacy itself.
Some non-Catholic Christian denominations, such as the Assyrian Church of the East, the Oriental Orthodox Church, the Eastern Orthodox Church, and the Anglican Communion, accept the doctrine of Apostolic Succession, and therefore accept (to varying extents) the claim that the Pope as successor to St. Peter is heir to Petrine primacy of honour. These churches deny, however, the claim that the Pope is also heir to Petrine primacy of jurisdiction. Because none of these denominations recognise the First Vatican Council as ecumenical, they regard its definitions of Papal jurisdiction and infallibility (and anathematisation of those who do not accept them) as non-binding.
Other non-Catholic Christian denominations do not accept the doctrine of Apostolic Succession, or do not understand it in hierarchical terms, and therefore do not accept the claim that the Pope is heir either to Petrine primacy of honour or to Petrine primacy of jurisdiction. These denominations vary from simply not accepting the Pope's authority as legitimate and valid, to believing that the Pope is the Antichrist or one of the beasts spoken of in the Book of Revelation. These denominations tend to be more heterogeneous amongst themselves than the aforementioned hierarchical churches, and their views regarding the Papacy and its institutional legitimacy (or lack thereof) vary considerably.
