Papacy - pāˈpəsē, office of the pope, head of the Roman Catholic Church. He is pope by reason of being bishop of Rome and thus, according to Roman Catholic belief, successor in the see of Rome (the Holy See) to its first bishop, St.
Peter. The pope therefore claims to be the shepherd of all Christians and representative (vicar or vicegerent) of Christ. The claim of Petrine supremacy and (by virtue of Peter's connection to Rome) Roman supremacy, is based on Matthew 16:18–19. Papal supremacy is not acknowledged outside the Roman Catholic Church. That church further holds that God will not permit the pope to make an error in a solemn official declaration concerning a matter of faith or morality (see
infallibility). The pope is also patriarch of the West; the great majority, although not all, of the Christians recognizing his authority as pope are also under his authority as
patriarch. This question of areas of authority is practical only with regard to some of the Eastern-rite patriarchs who may, for example, appoint bishops without papal confirmation. The pope generally lives in Rome, of which a portion (Vatican City) is politically independent and under his rule; the pope is thus head of a state and owes no political allegiance (see
Vatican;
Rome;
cardinal;
papal election). For a chronological list of popes and antipopes see the table entitled
Popes of the Roman Catholic Church. For the ecclesiastical framework, the teaching, the history, and the geographical distribution of the church, see

Christianity. In the Early Church There is no unequivocal evidence about the status of the pope in the earliest days of the church. That he was accorded special honor as the successor of St. Peter is acknowledged, but whereas Roman Catholic historians hold that the peculiar position of the Holy See was recognized and accorded authority, non-Catholic historians in general contend that the bishop of Rome was accorded honor over the other bishops, not authority. As missionaries sent directly from the city founded new churches throughout the West, more and more reverence was given to the pope. The Roman church was being enriched with gifts by converts, and it supported struggling young churches everywhere and supplied funds for charitable foundations all over Italy. As the political power of the city of Rome declined, the pope inherited some of the Roman emperor's position as symbol and defender of civilization. The combination of assurance and intrepidity in dealing with barbarian attacks and rulers of emerging states in this period (300–700) was a mark of the great popes—saints
Julius I,
Innocent I,
Leo I,
Gregory I, and
Martin I. The papacy gained prestige in the West and was powerful in doctrinal disputes, especially in the struggles over
Arianism,
Monophysitism, and
Monotheletism. In the Middle Ages A fateful event for the papacy was the donation of lands made to the pope by the Frankish king
Pepin the Short in 756. The papacy had already been given lands (since the 4th cent.), but it was the Donation of Pepin that came to be considered the real as well as the symbolic founding of the
Papal States. The pope thus became a powerful lay prince as well as an ecclesiastical ruler. This intermingling of powers was a determining condition in the struggle between
church and state that was a main theme in the history of the West in the
Middle Ages. Strong lay princes attempted to direct the church just as the pope tried to establish secular as well as spiritual supremacy over the rulers. A central point at issue in the 11th and 12th cent. was
investiture, but the conflict was far wider and deeper. Although all in the West affirmed that Christendom was under the pope in Rome, that affirmation had little bearing on the question of papal supremacy in secular affairs. By crowning (800)
Charlemagne,
Leo III at once sponsored the empire and sanctioned the creation of a state which, as the Roman Empire (see
Holy Roman Empire), was to be the chief antagonist of the papacy for centuries. The papacy reached a high point of corruption in the 10th cent., when the Holy See was cynically bought and sold. Under Leo IX reform began, but bitter feeling between East and West brought the break with patriarch of Constantinople (1054); late in the 11th cent. sweeping reforms were carried out by the forceful
Gregory VII. From that time forward the relative power of the papacy in quarrels with the emperor and with the kings of England, France, Naples, and Spain depended largely on the successes of individual popes and individual rulers. Pope
Alexander III was pitted against Roman Emperor
Frederick I and against King
Henry II of England, and Pope
Innocent III, despite opposition by Emperor
Otto IV and Emperor
Frederick II, made himself virtual arbiter of the West. Innocent's reign (1198–1216) marked the zenith of papal secular power. As a religious leader Innocent worked to reform clerical morals and combat heresy. He ordered (1208) a crusade against the heretical
Albigenses in S France that ended disastrously and cast a shadow over his pontificate. A century later
Boniface VIII, an able canon lawyer, proved himself no match for the ruthless king of France,
Philip IV. Pope
Clement V in 1309 deserted Rome for
Avignon and the domination of France. During the so-called Babylonian captivity (1309–78) all the popes were French, all lived at Avignon, and all were under the control of the French kings. The Avignonese papacy represented the culmination of the administrative structure of the church, which reached into almost all corners of Europe. Pope
Gregory XI—acting partly on the advice of St.
Catherine of Siena and St.
Bridget of Sweden—moved the papacy back to Rome. But the church was immediately plunged into the disorder of the Great
Schism (1378–1417). There were two or even three rival popes at a time (in later determination of true succession, those claimants ruled out of the succession are called antipopes). The schism ended in the Council of Constance (see
Constance, Council of). Since then, apart from the abortive revolt at the Council of Basel (see
Basel, Council of), there has been no schism in the papacy. Subsequently, the pope had little real power outside Italy, and no 15th-century pope was prepared to attempt serious reform, which would have required challenging the vested interests of bishops, cardinals, and princes. Indeed, in the 15th cent. the papal court made Rome a brilliant Renaissance capital, enriched by some of the finest art of the West. The Renaissance popes, however, were little distinguished from other princes in the extravagance and immorality of their courts. In the Reformation Papal corruption during the Renaissance provided the background for the Protestant
Reformation and alienated many followers of the established church. Martin
Luther and his colleagues entered upon a basic theological revolution, reacting in part to the state of the papacy. They denounced the whole accepted view of God's relation to humanity and began a movement that split the Western Church. Although reformation within the church began in the 1520s, papal involvement did not begin until the election (1534) of
Paul III (see
Counter Reformation). The Council of Trent (1545–47, 1551–52, 1562–63; see
Trent, Council of) undertook to lay out the new definitions and regulations that reconstructed the church, including the papacy. The other major work of the 16th-century popes was the new development of foreign missions, which, as in ancient times, enhanced papal prestige. Of the several orders concerned with reform and missions, the Jesuits (see
Jesus, Society of) were the best known. The 16th cent. also saw the stabilization of the Papal States as they would remain until the 19th cent. In the Eighteenth and Nineteenth Centuries After the Counter Reformation, the papacy continued to be plagued by another problem, one that reform had (of necessity) left untouched. This was the position in the church of the rulers of largely Roman Catholic states. Once one of these Catholic princes, whether devout or notoriously immoral, was sure of his power, he determined to include the church within it (e.g., insisting on the deciding voice in selecting the clergy). The kings of Spain even conducted their own
Inquisition. It was accepted that Catholic rulers should hold a veto in papal elections. By the 18th cent. every Catholic prince was at odds with the papacy. Spain had the longest record of this sort, lasting into the 20th cent. In France the triumphant Bourbons developed
Gallicanism as a theory to justify their ecclesiastical pretensions;
Louis XIV was its chief proponent, but the revolutionists of 1790 used it (in the Civil Constitution of the Clergy, banned by
Pius VI), and so did
Napoleon I as soon as he had signed the
Concordat of 1801. Most extreme, and least enduring, were the schemes of Holy Roman Emperor
Joseph II. In the 18th cent. the papacy seemed doomed; its weakness became a spectacle when
Clement XIV was forced into suppressing the Jesuits, the only group in the church consistently loyal to the pope. Early in the 19th cent., when
Pius VII tried to protect the sanctity of the Holy See, Napoleon had him ignominiously imprisoned. After the fall of Napoleon, with the increasing decline of the old absolutist states, the papacy imperceptibly gained. Papal opposition to the reunification of Italy deepened the suspicious dislike of most liberals for the papacy. The loss (1870) of the Papal States proved in the end a blessing for the papacy, although it took 60 years to solve the Roman Question—the problem of assuring the pope nonnational status in a nationally organized world (see
Lateran Treaty). The First
Vatican Council enunciated the doctrine of papal infallibility in 1870. In |
