Title and etymology The word
pope derives . In the early centuries of Christianity, this title was applied, especially in the East, to all
bishops and other senior clergy, and later became reserved in the West to the bishop of Rome during the reign of
Pope Leo I (440–461), a reservation made official only in the 11th century. The earliest record of the use of the title of 'pope' was in regard to the by-then-deceased
patriarch of Alexandria,
Heraclas (232–248). The earliest recorded use of the title "pope" in English dates to the mid-10th century, when it was used in reference to the 7th century Roman
Pope Vitalian in an Old English translation of
Bede's .
Position within the Church The Catholic Church teaches that the pastoral office, the office of
shepherding the Church, that was held by the apostles, as a group or "college" with
Saint Peter as their head, is now held by their successors, the bishops, with the bishop of
Rome (the pope) as their head. This gives rise to another title by which the pope is known: "supreme pontiff". The Catholic Church teaches that
Jesus personally appointed Peter as the visible head of the Church, and the Catholic Church's dogmatic constitution makes a clear distinction between apostles and bishops, presenting the latter as the successors of the former, with the pope as successor of Peter, in that he is head of the bishops as Peter was head of the apostles. Some historians argue against the notion that Peter was the first bishop of Rome, noting that the episcopal see in Rome can be traced back no earlier than the 3rd century. The writings of
Irenaeus, a
Church Father who wrote around 180 AD, reflect a belief that Peter "founded and organized" the Church at Rome. Moreover, Irenaeus was not the first to write of Peter's presence in the early Roman Church. The Church of Rome wrote in a letter to the Corinthians (which is traditionally attributed to
Clement of Rome ) about the persecution of Christians in Rome as the "struggles in our time" and presented to the Corinthians its heroes, "first, the greatest and most just columns", the "good apostles" Peter and
Paul.
Ignatius of Antioch wrote shortly after Clement; in his letter from the city of Smyrna to the Romans, he said he would not command them as Peter and Paul did. Given this and other evidence, such as Emperor Constantine's erection of the "
Old St. Peter's Basilica" on the location of
Saint Peter's tomb, as held and given to him by Rome's Christian community, many scholars agree that Peter was martyred in Rome under
Nero, although some scholars argue that he may have been martyred in Palestine. Although open to historical debate, first-century Christian communities may have had a group of presbyter-bishops functioning as guides of their local churches. Gradually, episcopal sees were established in metropolitan areas. Antioch may have developed such a structure before Rome. Some writers claim that the emergence of a single bishop in Rome probably did not occur until the middle of the 2nd century. In their view, Linus, Cletus and Clement were possibly prominent presbyter-bishops, but not necessarily monarchical bishops. though the detail of what this meant is unclear.
Early Christianity (c. 30–325) Sources suggest that at first, the terms and
presbyter were used interchangeably, with the consensus among scholars being that by the turn of the 1st and 2nd centuries, local congregations were led by bishops and presbyters, whose duties of office overlapped or were indistinguishable from one another. Some say that there was probably "no single 'monarchical' bishop in Rome before the middle of the 2nd century ... and likely later." In the early Christian era, Rome and a few other cities had claims on the leadership of worldwide Church.
James the Just, known as "the brother of the Lord", served as head of the
Jerusalem church, which is still honoured as the "Mother Church" in Orthodox tradition.
Alexandria had been a center of Jewish learning and became a center of Christian learning. Rome had a large congregation early in the apostolic period whom Paul the Apostle addressed in his
Epistle to the Romans, and according to tradition Paul was martyred there. During the 1st century of the Church (), the Roman capital became recognized as a Christian center of exceptional importance. The church there, at the end of the century, wrote an
epistle to the Church in
Corinth intervening in a major dispute, and apologizing for not having taken action earlier. There are a few other references of that time to recognition of the
authoritative primacy of the
Roman See outside of Rome. In the
Ravenna Document of 13 October 2007, theologians chosen by the Catholic and the Eastern Orthodox Churches stated: In AD 195, Pope Victor I, in what is seen as an exercise of Roman authority over other churches, excommunicated the
Quartodecimans for observing Easter on the 14th of
Nisan, the date of the Jewish
Passover, a tradition handed down by
John the Evangelist (see
Easter controversy). Celebration of Easter on a Sunday, as insisted on by the pope, is the system that has prevailed (see
computus).
Nicaea to East–West Schism (325–1054) The
Edict of Milan in 313 granted freedom to all religions in the Roman Empire, beginning the
Peace of the Church. In 325, the
First Council of Nicaea condemned
Arianism, declaring
trinitarianism dogmatic, and in its sixth canon recognized the special role of the Sees of Rome, Alexandria, and Antioch. Great defenders of Trinitarian faith included the popes, especially
Liberius, who was exiled to
Berea by
Constantius II for his Trinitarian faith,
Damasus I, and several other bishops. In 380, the
Edict of Thessalonica declared
Nicene Christianity to be the state religion of the empire, with the name "Catholic Christians" reserved for those who accepted that faith. While the civil power in the
Eastern Roman Empire controlled the church, and the
patriarch of Constantinople, the capital, wielded much power, in the
Western Roman Empire, the bishops of Rome were able to consolidate the influence and power they already possessed.
Clovis I, king of the
Franks, was the first important barbarian ruler to convert to the mainstream church rather than Arianism, allying himself with the papacy. Other tribes, such as the
Visigoths, later abandoned Arianism in favour of the established church. This practice had become common in part because the prelates and secular rulers were also often participants in public life. To combat this, and other practices that had been seen as corrupting, between the years 900 and 1050, centres emerged promoting ecclesiastical reform, the most important being the
Abbey of Cluny, which spread its ideals throughout Europe. In 1095, the Byzantine emperor,
Alexios I Komnenos, asked for military aid from
Pope Urban II in the ongoing
Byzantine–Seljuq wars. Urban, at the
council of Clermont, called the
First Crusade to assist the Byzantine Empire to regain the old Christian territories, especially Jerusalem.
East–West Schism to Reformation (1054–1517) began in 1054 and continues, while the
Western Schism lasted from 1378 to 1417. With the
East–West Schism, the
Eastern Orthodox Church and the Catholic Church split definitively in 1054. This fracture was caused more by political events than by
slight divergences of creed. Popes had galled the Byzantine emperors by siding with the king of the Franks, crowning a rival Roman emperor, appropriating the
Exarchate of Ravenna, and driving into Greek Italy. In the
Middle Ages, popes struggled with monarchs over power. Various
Antipopes challenged papal authority, especially during the
Western Schism (1378–1417). It came to a close when the
Council of Constance, at the high point of Concilliarism, decided among the papal claimants. The Eastern Church continued to decline with the Eastern Roman (Byzantine) Empire, undercutting Constantinople's claim to equality with Rome. Twice an Eastern emperor tried to force the Eastern Church to reunify with the West. First in the
Second Council of Lyon (1272–1274) and secondly in the
Council of Florence (1431–1449). Papal claims of superiority were a sticking point in reunification, which failed in any event. In the 15th century, the
Ottoman Empire captured
Constantinople and ended the Byzantine Empire.
Reformation to present (1517 to today) (1534–1549) initiated the
Council of Trent (1545–1563), which established the triumph of the papacy over those who sought to reconcile with Protestants or oppose papal claims.
Protestant Reformers criticized the papacy as corrupt and characterized the pope as the
antichrist. Popes instituted a
Catholic Reformation Gradually forced to give up secular power to the increasingly assertive
European nation states, the popes focused on spiritual issues. Later the same year,
Victor Emmanuel II of Italy seized Rome from the pope's control and substantially completed the
unification of Italy. In 1929, the
Lateran Treaty between the
Kingdom of Italy and the Holy See established
Vatican City as an independent
city-state, guaranteeing papal independence from secular rule. In 1950,
Pope Pius XII defined the
Assumption of Mary as dogma, the only time a pope has spoken since papal infallibility was explicitly declared. The
Primacy of St. Peter, the controversial doctrinal basis of the pope's authority, continues to divide the eastern and western churches and to separate Protestants from Rome. == Early Christian mentions ==
