The primacy of Peter, also known as Petrine primacy (from the ), is the position of preeminence that is attributed to Peter among the Twelve Apostles of Christianity.

Primacy of Peter among the Apostles The Evangelical Dictionary of Theology illustrates the leading role that Peter played among the Apostles, speaking up on matters that concern them all, being called by Jesus by a name linking him with the rock on which Jesus would build his church, being charged with pastoring the flock of Christ, and taking the leading role in the initial church.Walter A. Elwell (editor), Evangelical Dictionary of Theology (Baker Academic 2001 ), entry "Peter, Primacy of"

There is general agreement among scholars on the preeminence that the historical Peter held among the disciples of Jesus, making him "the most prominent and influential member of the Twelve during Jesus' ministry and in the early Church".Theodore Stylianopoulos "Concerning the Biblical Foundation of Primacy", in Walter Kasper (editor), The Petrine Ministry (Paulist Press 2008 ), pp. 43–44, citing John P. Meier, A Marginal Jew. 3. Companions and Competitors (Knopf Doubleday 2001 ), pp. 221–225, and others.

In one interpretation, the prominence that the New Testament and other early Christian writings attribute to Peter is due to their seeing him as a unifying factor in contrast to other figures identified with disputed interpretations of Christianity."For Peter was probably in fact and effect the bridge-man (pontifex maximus!) who did more than any other to hold together the diversity of first-century Christianity. James the brother of Jesus, and Paul of Tarsus, the two other most prominent leading figures in first-century Christianity, were too much identified with their respective "brands" of Christianity, at least in the eyes of Christians at the opposite ends of this particular spectrum. But Peter, as shown particularly by the Antioch episode in , had both care to hold firm to his Jewish heritage – which Paul lacked – and an openness to the demands of developing Christianity, which James lacked. John might have served as a figure of the center holding together the extremes, but if the writings linked with his name are at all indicative of his own stance, he was too much of an individualist to provide such a rallying point. Others could link the developing new religion more firmly to its founding events and to Jesus himself. But none of them, including the rest of the twelve, seem to have played any role of continuing significance for the whole sweep of Christianity—though James the brother of John might have proved an exception had he been spared."

Catholic view In Catholicism, it is held that the primacy of Peter is a basis for the primacy of the bishop of Rome over other bishops throughout the Catholic Church. This extension of Petrine primacy to popes is known as the primacy of the Bishop of Rome. This Catholic Church doctrine holds that the pope as Bishop of Rome has authority delegated from Jesus to rule over the entire Church. There are various views on the nature of the primacy and how it has been exercised and passed on. This belief makes a distinction between the personal prestige of Peter and the supremacy of the office of pope which Catholics believe Jesus instituted in the person of Peter.

In the New Testament, which some call the New Law or "New Greek Testament",Knight, Kevin. "Question 106. The law of the Gospel, called the New Law, considered in itself." New Advent. 11 September 2009: https://www.newadvent.org/summa/2106.htm Matthew 16:16–18 reports that Jesus changed Simon's name to Peter. Elsewhere in Scripture such a name change always denotes some change in status (e.g., Abram to Abraham, or Jacob to Israel). In the gospels, Peter is shown as a close associate of Jesus. His home at Capernaum was at Jesus' disposal, as was his fishing boat, when needed. Jesus cured Peter's mother-in-law, and Peter was among those who attended the wedding at Cana. He plays a prominent part in the account of the miraculous catch of fish, and the walking on the water."The Primacy of Peter", Catholic Tradition In John 20, when Peter and the other disciple run to the empty tomb, the other disciple arrives first, but it is Peter who enters the tomb.

Though among the twelve disciples, Peter is predominant in the first chapters of Acts of the Apostles, the focus shifting to Paul in the later chapters. James the Just, "the brother of the Lord" (Galatians 1:19), appears as the bishop of Jerusalem at the earliest church community in Acts 15. The Ecclesiastical History (4th century) states: "James, ... was the first (as the records tell us) to be elected to the episcopal throne of the Jerusalem church.... Clement, in Outlines Book VI, puts it thus, 'Peter, James and John, after the Ascension of the Saviour, did not claim pre-eminence because the Saviour had especially honored them, but chose James the Righteous as Bishop of Jerusalem.... James the Righteous, John, and Peter were entrusted by the Lord after his resurrection with the higher knowledge. They imparted it to the other apostles, and the other apostles to the seventy...Eusebius. Ecclesiastical History. Book 1:1.

For Catholics, St. Peter is commonly considered the first Bishop of Jerusalem. However, they believe the bishop of Jerusalem was not by that fact the head of the Catholic church, since the leadership rested in Peter as the "Rock" and "Chief Shepherd".Mckenzie, John L. The Dictionary of the Bible (Catholic) Catholics who believe Peter was the first bishop of Jerusalem also believe he entrusted the community to James when he was forced to leave Jerusalem, due to Herod Agrippa's persecution.The Navarre Bible, footnotes

The 4th century Latin Father Jerome, in his epistle to Augustine of Hippo, wrote that "nay more, that Peter was the prime mover in issuing the decree by which this was affirmed", in relation to the Council of Jerusalem, and again, "and to his opinion the Apostle James, and all the elders together, gave consent".

Jesus said to Peter in verse 19, "I will give to thee the keys of the kingdom of heaven." Especially for the Hebrew people, keys were a symbol of authority; keys are also used to symbolise power over death in Revelation 1:18. Cardinal Gibbons, in his book The Faith of Our Fathers, points out that keys are still a symbol of authority in today's culture; he uses the example of someone giving the keys of his house to another person, and that the latter represented the owner of the house in his absence. In receiving the keys, Peter takes on the office of prime minister, which was well-known to ancient and contemporary Hebrews, and depicted in the Old Testament, as the one who had authority from God to bind and loose.

The Dogmatic Constitution, Pastor aeternus, issued by the First Vatican Council, defined the primacy of the bishop of Rome over the whole Catholic Church as an essential institution of the church that can never be relinquished. This is based on the statement in Matthew 16:18 "And so I say to you, you are Peter, and upon this rock I will build my church, and the gates of the netherworld shall not prevail against it", and John 21:17 "He said to him the third time, 'Simon, son of John, do you love me?' Peter was distressed that he had said to him a third time, 'Do you love me?' and he said to him, 'Lord, you know everything; you know that I love you.' [Jesus] said to him, 'Feed my sheep. This conversation with Peter established Peter as the leader of the disciples in Jesus' absence."Church of the Primacy of Peter", FaithND

In December 1996, the Congregation for the Doctrine of the Faith held a doctrinal symposium on "The Primacy of the Successor of Peter". One of the "Reflections" on the essential points of Catholic doctrine on the primacy is that it is a necessary service to unity."The Primacy of the Successor of Peter in the Mystery of the Church", CDF A listing of some of the essential points of the doctrine was issued by the prefect of the CDF, Cardinal Joseph Ratzinger. Noting that in the list of the Twelve Apostles in the Synoptics and Acts, Simon/Peter appears first.

The Catechism of the Catholic Church states:

Individuals supporting Roman primacy Both Latin and Greek writers in the early church referred to "rock" as applying to both Peter personally and his faith symbolically, as well as seeing Christ's promise to apply more generally to his twelve apostles and the Catholic Church at large.

Irenaeus Irenaeus has been called the most important witness of Christianity in the 2nd century.Giles, E., ed. (1952). "Documents Illustrating Papal Authority: A.D. 96–454". London: S.P.C.K. p. 6. Taught by Polycarp, who had been instructed by John the apostle, Irenaeus became Bishop of Lyon in 178. In his Against the Heresies, Irenaeus wrote, "Although there are many dialects in the world, the force of the tradition is one and the same. For the same faith is held and handed down by the churches established in the German states, the Spains, among the Celtic tribes, in the East, in Libya, and in the central portions of the world."Giles, E., ed. (1952). Documents Illustrating Papal Authority: A.D. 96–454. London: S.P.C.K. p. 8. In Book 3, Irenaeus continues his defense of the unity of the church around the bishop, writing, "By pointing out the apostolic tradition and faith announced to mankind, which has been brought down to our time by successions of bishops, in the greatest, most ancient, and well known church, founded and established by the two most glorious apostles, Peter and Paul, at Rome, we can confound all who in any other way... gather more than they ought."Giles, E., ed. (1952). Documents Illustrating Papal Authority: A.D. 96–454. London: S.P.C.K. p. 9.

Irenaeus asserted the Doctrine of Apostolic Succession to counter the claims of heretics, especially the Gnostics who were attacking the theology and authority of the mainstream church. He stated that one could find true teaching in several leading episcopal sees, not just at Rome. The doctrine he asserted, therefore, has two parts: lineage from the Apostles and right teaching.

Ignatius of Antioch Ignatius, bishop of Antioch, was well known for his insistence on the authority of the bishop. In his writings to the church at Smyrna in 115 AD, he encouraged the Smyrnaeans to "Avoid divisions, as the beginning of evil. Follow, all of you, the bishop, as Jesus Christ followed the father; and follow the presbytery as the apostles. Let no man do aught pertaining to the Church apart from the bishop. Wheresoever the bishop appears, there let the people be, even as wheresoever Christ Jesus is, there is the Catholic Church."Giles, E., ed. (1952). Documents Illustrating Papal Authority: A.D. 96–454. London: S.P.C.K. p. 4.
