Papacy

Intro

"The papacy is the oldest continuously functioning institution in the Western world. Every other office (Roman emperor, medieval monarchy, parliamentary government) has come and gone; the bishop of Rome has been in his see, with brief interruptions, for nearly two thousand years."

The papacy is the office of the bishop of Rome, who in Catholic teaching is the successor of the apostle Peter and the visible head of the universal church. There are about 1.3 billion Roman Catholics in the world today, and all of them recognize the pope as their chief shepherd. There are no other Christian traditions that share that view in its full Catholic form. Eastern Orthodox Christians regard the pope as the bishop of one local church (an important one, historically the first in order of honor) but not as the head of the whole church. Protestants reject the office entirely.

The institution evolved in stages. In the first century, Peter and Paul ministered and died at Rome. By the late second century, the church at Rome had unusual prestige because it was the imperial capital and because it could trace its founding to two apostles. By the fifth century, Pope Leo the Great was articulating a theology of the papal office in mature form, claiming that Peter spoke through the pope. By the eleventh century, Pope Gregory VII could write the Dictatus Papae asserting that the pope could depose emperors. By the thirteenth century, Pope Innocent III was effectively the most powerful figure in Europe. By 1870, the First Vatican Council had defined papal infallibility, the strongest claim ever made for the office.

Then came a counter-arc. The Protestant Reformation in the sixteenth century rejected the papacy outright. The Avignon Papacy of the fourteenth century (when seven popes in succession resided in southern France under French influence) and the Western Schism that followed (when three rival claimants each declared himself the true pope) damaged the office's prestige. The papacy lost its temporal territories in 1870 when the Kingdom of Italy seized the Papal States. The Second Vatican Council (1962 to 1965) re-described papal authority in collegial terms, the pope working with the bishops rather than ruling over them.

The current papacy is a curious mix of old and new. The pope is still a head of state (Vatican City, the smallest sovereign state in the world). He is also a global media figure, with travels, encyclicals, and tweets. He oversees one of the world's largest charitable networks. He claims, in the strongest form of Catholic teaching, to be the successor of Peter with the ability to teach without error on matters of faith and morals.

This page covers all of that as history and institution. The biblical question, whether Peter himself had a unique office that could be passed on at all, is treated separately on Petrine Primacy. The wider Catholic Church is treated on Catholic Church.

A short note on language: the word pope comes from the Latin papa, originally a term of affection meaning father and applied in the early centuries to any senior bishop. By the eleventh century the term had been reserved for the bishop of Rome alone in Western usage. Eastern Orthodox usage still applies papa to other senior clergy (the bishop of Alexandria is the Coptic Pope, for example).

In full

The Papacy is the institution of the Bishop of Rome considered as a single continuous office, held in Catholic teaching to be of divine institution, descended from the apostle Peter as his episcopal successor, and exercising universal pastoral, doctrinal, and jurisdictional authority over the worldwide Catholic Church. Its formal claims rest on the doctrine of Petrine Primacy grounded in Matthew 16:18-19, Luke 22:32, and John 21:15-17, on a continuous succession of bishops at Rome from Peter (whose martyrdom in the city under Nero c. AD 64 is attested by 1 Clement 5, Ignatius, Irenaeus, and Eusebius), and on the lived practice of Roman intervention in the doctrinal and disciplinary affairs of the wider church traceable from the late first century. Its developed dogmatic formulation was given at the First Vatican Council (Pastor Aeternus, 1870), which defined two prerogatives: universal ordinary jurisdiction of the Roman Pontiff over the entire church, and papal infallibility when the pope speaks ex cathedra on matters of faith and morals. The Second Vatican Council (Lumen Gentium, 1964) reframed papal authority in collegial terms (the pope as head of the college of bishops sharing in supreme church authority) without retracting Vatican I. Eastern Orthodox theology grants the bishop of Rome a primacy of honor within the ancient pentarchy (the five great patriarchates: Rome, Constantinople, Alexandria, Antioch, Jerusalem) but rejects universal jurisdictional primacy and infallibility as Western innovations. Reformation and post-Reformation Protestant traditions reject the papal office in toto, holding that no New Testament warrant exists for a single universal episcopal head and that Christ alone is the head of the church (Westminster Confession of Faith 25.6; Belgic Confession Art. 31).

The first century: Peter and Paul at Rome

The papacy's foundation rests on the claim that Peter ministered, died, and was buried at Rome.

Peter at Rome. The New Testament does not explicitly place Peter at Rome (1 Peter 5:13's reference to "Babylon" is generally understood as code for Rome, but does not constitute a clear claim). The strongest early evidence comes from the First Letter of Clement (c. AD 96), which speaks of Peter and Paul as the two great Roman apostolic martyrs; from Ignatius of Antioch (c. AD 107, Letter to the Romans 4); from Dionysius of Corinth (c. AD 170) cited in Eusebius; and from Irenaeus (c. AD 180, Against Heresies 3.3.2-3) who calls Rome the church "founded and organized at Rome by the two most glorious apostles, Peter and Paul."
Peter's grave at the Vatican Hill. Excavations under St. Peter's Basilica in the 1940s and 1950s (under Pius XII) revealed an early Christian shrine over what was understood from the second century onward to be Peter's tomb. The identification is widely (though not universally) accepted by modern archaeology.
Paul at Rome. Acts ends with Paul under house arrest in Rome (c. AD 60 to 62). The First Letter of Clement and tradition place his execution along the Ostian Road outside Rome, traditionally during the Neronian persecution of c. AD 64 or 67.

The first-century evidence is enough to ground the historical claim that Peter and Paul ministered and died at Rome. It does not, on its own, ground the claim that Peter founded a perpetual office of jurisdictional primacy. That question lives on Petrine Primacy.

The second to third centuries: a senior see, not yet a monarchical papacy

The bishop of Rome in the second and third centuries was a senior figure but not a universal monarch.

Clement of Rome's letter to Corinth (c. AD 96) intervened in a Corinthian church dispute. Catholic historians read this as the first Roman exercise of pastoral authority over another church; Protestant historians point out the letter is written in the name of the Roman church corporately, not by Clement as monarchical pope.
The episcopal lists. Irenaeus (c. 180) and Eusebius (c. 320) preserve lists of Roman bishops from Peter onward (Peter, Linus, Anacletus, Clement, Evaristus, Alexander, etc.). The lists are the basis for Catholic claims to apostolic succession at Rome.
Conflicts of authority. When Pope Victor I (c. 189 to 199) attempted to enforce the Roman date for Easter on the churches of Asia Minor, he was rebuked by Irenaeus and other bishops, who treated the Roman bishop as a peer, not a sovereign.
Cyprian of Carthage (d. 258) acknowledged Roman honor (calling Rome "the chair of Peter") while insisting that "the episcopate is one, of which each bishop holds his part in the totality." He directly confronted Pope Stephen over the rebaptism of those baptized by heretics.

The Roman church was distinguished but not yet supreme. Disputes were typically resolved by regional councils, not by Roman fiat.

The fourth to fifth centuries: imperial Christianity and the rise of the papal claim

Three developments transformed the Roman bishop's status.

The Edict of Milan (313) legalized Christianity. Within a century, the empire was officially Christian and the bishop of Rome was an imperial figure.
The relocation of imperial power to Constantinople (330) left a power vacuum in the West that the bishop of Rome increasingly filled.
The Western theological tradition stabilized around Latin-speaking authorities, with Rome as the senior see.

The first articulate theology of the papal office was developed by Leo the Great (pope 440 to 461). Leo claimed that the apostle Peter continued to speak through the bishop of Rome, that the pope held the plenitudo potestatis (the fullness of power), and that papal pronouncements carried Petrine authority. His Tome (449), defining the two natures in Christ, was read at the Council of Chalcedon (451) and reportedly hailed by the bishops with the cry "Peter has spoken through Leo!"

The same Chalcedon, however, also issued Canon 28 giving the bishop of Constantinople equal honor with the bishop of Rome (because Constantinople was the new imperial capital). Leo rejected the canon. The disagreement foreshadowed the great schism with the East.

Gregory the Great (pope 590 to 604) consolidated the office further, reformed the liturgy, sent missions to convert the Anglo-Saxons (Augustine of Canterbury, 597), and exercised political authority in the absence of effective imperial protection. Gregory styled himself servus servorum Dei (servant of the servants of God), a title popes still use.

The medieval high papacy (c. 1050 to 1300)

The medieval period saw the papacy reach the height of its temporal and spiritual claims.

The Gregorian Reform (c. 1050 to 1100). Pope Gregory VII (1073 to 1085) led a sweeping reform of clerical morals and church-state relations. His Dictatus Papae (1075) asserted, among twenty-seven propositions, that the pope alone could depose bishops, that the pope could be judged by no one, that the pope could depose emperors, and that the Roman Church had never erred and never would err. The most famous moment was the Investiture Controversy with Emperor Henry IV, culminating in Henry's barefoot penance in the snow at Canossa (1077).
The East-West Schism (1054). Cardinal Humbert of Silva Candida, papal legate to Constantinople, mutually excommunicated Patriarch Michael Cerularius. The breach had been building for centuries (over papal primacy, the Filioque clause, the use of unleavened bread in the Eucharist, clerical celibacy). The 1054 excommunications were lifted by Paul VI and Athenagoras I in 1965, but the schism itself persists.
The Crusades (1095 to 1291). Pope Urban II called the First Crusade at the Council of Clermont (1095). The papacy claimed authority to direct armies in defense of Christendom.
Innocent III (pope 1198 to 1216). Innocent claimed the pope was "set between God and man, lower than God but higher than man." He summoned the Fourth Lateran Council (1215), the high-water mark of medieval canon law. He directed the Albigensian Crusade against the Cathars, deposed King John of England, and was the effective political arbiter of Europe.
Boniface VIII (pope 1294 to 1303). His bull Unam Sanctam (1302) declared that "submission to the Roman Pontiff is altogether necessary for salvation for every human creature." Boniface was attacked at Anagni by agents of Philip IV of France and died shortly afterward, marking the end of the high papal era.

The Avignon Papacy and the Western Schism (1309 to 1417)

A century of crisis followed.

The Avignon Papacy (1309 to 1377). Seven successive popes resided in Avignon in southern France under heavy French influence. Petrarch called it the "Babylonian Captivity" of the Church. Papal prestige declined; the papal court was widely accused of corruption and worldliness.
The Western Schism (1378 to 1417). When Gregory XI returned the papacy to Rome and died there in 1378, the cardinals elected Urban VI, then disowned him as mentally unstable and elected Clement VII, who returned to Avignon. Western Christendom now had two popes, each claiming legitimacy, each excommunicating the other, each backed by different European kingdoms. The crisis deepened when the Council of Pisa (1409) tried to settle the matter by electing a third pope, producing three rival claimants.
The Council of Constance (1414 to 1418). Resolved the schism by deposing or accepting the resignation of all three claimants and electing Martin V (1417). The council also passed the decree Haec Sancta asserting that a general council has authority over the pope (the conciliarist position).
Eugenius IV (pope 1431 to 1447) subsequently rejected conciliarism and restored papal supremacy, but the office's reputation had been permanently damaged.

The Reformation crisis (sixteenth century)

The papacy of the late fifteenth and early sixteenth centuries was characterized by Renaissance worldliness and political entanglement. Popes like Alexander VI Borgia (1492 to 1503) and Julius II (1503 to 1513) were as much princes as priests. The sale of indulgences to fund the rebuilding of St. Peter's Basilica triggered Martin Luther's Ninety-Five Theses (1517).

The Protestant reformers rejected the papacy categorically:

Luther initially appealed to the pope against indulgence abuses, then progressively identified the papacy with the Antichrist of 2 Thessalonians 2.
Calvin in the Institutes (Book 4, ch. 6 to 7) systematically dismantled the case for papal primacy.
The Anglican Reformation rejected papal authority and substituted the monarch as supreme governor of the Church of England (Act of Supremacy, 1534).

The Catholic response was the Council of Trent (1545 to 1563), which reaffirmed Catholic teaching on the sacraments, justification, scripture and tradition, and the role of the bishops, without directly defining papal infallibility. Trent shaped Catholic life until Vatican II.

The early modern papacy (seventeenth to nineteenth centuries)

The papacy gradually lost political dominance.

The Galileo affair (1633) damaged the papacy's reputation among the new scientific establishment.
Gallicanism (in France) and Josephinism (in Austria) asserted national church autonomy from Rome.
The French Revolution (1789 onward) attempted to nationalize the church; Pope Pius VI died a prisoner of the revolutionary regime in 1799.
Napoleon crowned himself in Pius VII's presence (1804), then later imprisoned the same pope.
The Papal States (the central Italian territories ruled by the pope since the Donation of Pepin in 756) were progressively absorbed by the Kingdom of Italy, finally falling with the seizure of Rome itself in 1870.

In response to this loss of temporal power, the spiritual claims of the papacy were sharpened.

The First Vatican Council (1869 to 1870)

Pope Pius IX (1846 to 1878) convened the First Vatican Council. Its constitution Pastor Aeternus defined two doctrines:

Universal ordinary jurisdiction. "This power of jurisdiction of the Roman Pontiff is both episcopal and immediate. Toward it pastors and faithful of whatever rite and dignity, both individually and collectively, are bound by the duty of hierarchical subjection and true obedience."
Papal infallibility. "The Roman Pontiff, when he speaks ex cathedra, that is, when in discharge of the office of pastor and teacher of all Christians, by virtue of his supreme apostolic authority, he defines a doctrine regarding faith or morals to be held by the universal Church, by the divine assistance promised to him in blessed Peter, is possessed of that infallibility with which the divine Redeemer willed that His Church should be endowed in defining doctrine regarding faith or morals."

Conditions for an infallible ex cathedra statement: the pope must be (a) speaking as pope, (b) addressing the whole church, (c) defining a doctrine of faith or morals, (d) intending to engage his supreme apostolic authority. Ex cathedra statements are rare; the only universally agreed instances since 1870 are the definitions of the Immaculate Conception of Mary (1854, technically before Vatican I but generally treated as paradigmatic) and the bodily Assumption of Mary (1950).

The minority bishops at Vatican I (including the German and American bishops most worried about the political reception of the doctrine) acquiesced after the vote. Some, including the historian-bishop Ignaz von Döllinger, refused and left the church, forming the Old Catholic Church.

The Second Vatican Council (1962 to 1965)

Pope John XXIII (1958 to 1963) convened the Second Vatican Council with a different posture, seeking aggiornamento (bringing up to date). The council's dogmatic constitution Lumen Gentium (1964) reframed the papal office in collegial terms:

The college of bishops, with and under the pope, exercises supreme authority over the church.
The pope remains its head and acts both with the college and at times alone, but the bishops are not merely his delegates.
Local bishops have ordinary jurisdiction in their own dioceses by divine right, not by papal delegation.

Vatican II also dramatically opened Catholic engagement with non-Catholic Christians (the decree Unitatis Redintegratio), with non-Christian religions (Nostra Aetate), and with the modern world (Gaudium et Spes). The papal office became more pastoral and less monarchical in style without changing the dogmatic substance.

The modern papacy

Paul VI (1963 to 1978) continued Vatican II's reception, traveled internationally, and issued Humanae Vitae (1968) reaffirming traditional teaching against artificial contraception.
John Paul II (1978 to 2005) reshaped the modern papacy through international travel (104 trips), engagement with non-Catholic Christians and with Judaism, opposition to communism in Eastern Europe, and a long, public, photogenic decline that ended with his death in 2005. His encyclical Ut Unum Sint (1995) invited dialogue about the form of the papal ministry in a reunified church.
Benedict XVI (2005 to 2013) is best known as a theologian (Joseph Ratzinger) and for his resignation, the first papal resignation since Gregory XII in 1415.
Francis (2013 to 2025), the first Latin American and the first Jesuit pope, emphasized pastoral mercy, ecological responsibility (Laudato Si', 2015), and engagement with the poor.

The non-Catholic views

Eastern Orthodox

Eastern Orthodox theology grants Rome a primacy of honor among the ancient patriarchates but rejects universal jurisdiction and infallibility. Orthodox theologians have offered to discuss a renewed Petrine ministry in a reunified church (responses to Ut Unum Sint), but on terms incompatible with Vatican I's mature claims.

Protestant

Protestant traditions across the spectrum (Lutheran, Reformed, Anglican, Baptist, Methodist, Pentecostal) reject the papal office. Key elements:

No New Testament warrant. The New Testament knows no single universal episcopal head.
Christ alone as head of the church. Ephesians 1:22-23, Colossians 1:18.
The doctrine developed in stages. What develops over fifteen centuries cannot have been instituted by Christ in apostolic clarity.
Historical abuses (the medieval indulgence trade, the Avignon worldliness, the Borgia popes) undermined Roman credibility in the sixteenth century and are still cited.

The classic Protestant identification of the papacy with the Antichrist (Luther, Calvin, the Westminster Confession 25.6) is largely retired in contemporary mainline Protestantism but still affirmed by some confessional Reformed and Lutheran bodies.

Old Catholic, Independent Catholic, and similar bodies

Various bodies have separated from Rome over papal claims while preserving Catholic sacramental and liturgical forms: the Old Catholics (after Vatican I), the Polish National Catholic Church, and various smaller independent jurisdictions.

Tensions

Development vs novelty. Catholics argue the papal office developed organically from apostolic seeds. Critics argue what developed was a Roman political-ecclesial structure with little continuity to the New Testament Peter.
Conciliar vs papal. The conciliarist tradition within Catholicism (Constance, Basel) held that general councils have authority over the pope. The papal absolutist tradition (Vatican I) reversed that. The argument is not entirely settled in Catholic theology.
Infallibility's scope. What exactly counts as an ex cathedra statement? How does ordinary papal teaching differ in authority? The questions are technically contested even within Catholic theology.
The historical popes. The Catholic Church has not always had reputable popes (the Borgia popes, the Avignon popes, John XII who reportedly died in adultery). Catholic theology distinguishes the office from the man holding it, but the historical record makes the Petra foundation argument harder to maintain in some periods.
The ecumenical question. The papacy remains the central obstacle in Catholic-Orthodox and Catholic-Protestant reunion. Modern Catholic and Orthodox dialogues (the Ravenna Document, 2007) explore how Petrine ministry could be exercised more synodally without retracting Vatican I.

Significance

Institutional. The longest continuous office in the Western world. The papacy outlasted the Roman Empire, the medieval kingdoms, and the modern colonial powers.
Doctrinal. For Catholics, the indispensable visible center of Christian unity. For Protestants, the institutional embodiment of the corruption of apostolic Christianity.
Political. The pope is still a head of state (Vatican City) and a global moral voice.
Ecumenical. The papacy is the live question in Catholic-Orthodox and Catholic-Protestant reunion negotiations.
