Apostle Peter

Simon, later called Peter, was a first-century Jewish fisherman from Bethsaida on the northern shore of the Sea of Galilee. The New Testament names him son of Jonah (or John) and brother of the apostle Andrew. The Gospel of John identifies Bethsaida as the city of Andrew and Peter; the Synoptic Gospels place his household in Capernaum, where Jesus healed Peter’s mother-in-law, which is the principal evidence that Peter was married. He worked the lake as a fisherman, at times with James and John, the sons of Zebedee. The Gospels recount that Jesus called Simon and Andrew from their nets to become fishers of people, and that Simon received the name Cephas (Aramaic) or Petros (Greek), meaning “rock.” No contemporary source records a year of birth, and later estimates are conjectural.

Peter belongs to the inner circle of Jesus’ disciples and stands first in New Testament lists of the Twelve. The Gospels present him as spokesman of the group: he confesses Jesus as Messiah at Caesarea Philippi, is present at the Transfiguration, attempts to walk on the water, and, in Matthew, is associated with the saying about the keys of the kingdom and binding and loosing. The same narratives show him as impulsive and fallible: he rebukes Jesus over the Passion, sleeps in Gethsemane, and three times denies knowing Jesus during the trial. The Fourth Gospel and the appendix of John 21 describe a post-resurrection appearance by the Sea of Galilee in which the risen Jesus restores Peter and charges him to feed his sheep. These first-century texts are the main sources for Peter’s life with Jesus; they are theological portraits, not modern biographies, and they do not date his birth or death.

In the Acts of the Apostles, Peter is the leading figure of the Jerusalem community in the years after Jesus’ death. He preaches at Pentecost, is associated with healings, and speaks before the Sanhedrin. Acts attributes to him the baptism of the Gentile Cornelius of Caesarea, a turning point in the inclusion of non-Jews. He appears at the Council of Jerusalem, which addressed Gentile converts and the Mosaic law. Paul’s letter to the Galatians, a first-century source, mentions a confrontation at Antioch in which Paul opposed Cephas over table fellowship with Gentiles, showing that Peter traveled and that the two apostles did not always agree. Clement of Alexandria, writing around the turn of the third century, states that Peter was married and that he and Philip had children; the wife’s name is not given in early reliable sources. The New Testament itself does not narrate Peter’s later years or his death.

Later Christian tradition, already attested in the late first and second centuries, places Peter in Rome and identifies him as a martyr under Nero. The First Letter of Clement, written from Rome toward the end of the first century, refers to Peter’s martyrdom without specifying place or date. By the later second century, Irenaeus and, in the third century, Origen (as reported by Eusebius) associated Peter with Rome and with crucifixion; a tradition that he was crucified head downward appears in the apocryphal Acts of Peter and in Origen. Ancient chronology is not precise: martyrdom is commonly situated in the mid-60s of the first century, during or after Nero’s persecution following the fire of Rome, but no contemporary document records the exact year. Tradition also holds that Peter led the church in Antioch before going to Rome; later episcopal lists of Antioch and of Rome name him as first bishop of those sees. Catholic tradition regards him as the first Bishop of Rome and thus the first pope; Eastern tradition honors him as founder of the church of Antioch, later counted among the patriarchates.

Veneration of Peter is ancient. A memorial on the Vatican hill is mentioned by the Roman presbyter Gaius around the turn of the third century; Constantine built a basilica over the site in the fourth century, and the present St. Peter’s Basilica stands over the same area, where a tomb traditionally identified as Peter’s is located in the Vatican necropolis. The principal feast of Saints Peter and Paul is kept on 29 June in East and West; other observances include the Chair of Saint Peter. He is invoked as patron of fishermen, net makers, shipwrights, locksmiths, the papacy, and Rome, among many other causes and places. His name and the Petrine texts of the New Testament have been central to later debates about church authority, especially the role of the Bishop of Rome. Historical reconstruction beyond the New Testament and the earliest Roman traditions remains limited; named wives, a daughter Petronilla, and detailed itineraries belong to later hagiography and are not verified by first-century sources.
