Saint Peter

• 1. Introduction

  ›

  Saint Peter began life as Shimon bar Yonah, a fisherman from Bethsaida. He died, according to tradition, crucified upside down on Vatican Hill under the Emperor Nero. Between those two points lies one of the most consequential lives in the history of religion. How does a man who pulled nets on the Sea of Galilee become the figure upon whom an institution of global reach claims its founding authority? And how does someone whose own gospels record three explicit betrayals of his teacher end up remembered as the rock on which a church was built? These are the questions that make Peter so enduring, and so human.

• 2. A Fisherman's Name

  Simon was his birth name, the son of a man called Jonah or John. In only two New Testament passages does his name appear as "Simeon" rather than "Simon", a variation scholars link to the Jewish practice of pairing a Hebrew patriarchal name with a similar-sounding Greek or Roman equivalent. The name Peter came later, a gift from Jesus himself at Caesarea Philippi. Jesus gave him the Aramaic name Cephas, from a word whose precise meaning scholars still debate. Some say it means rock or crag; others say stone, with the particular sense of a jewel. Catholic theologian Rudolf Pesch argued the Aramaic would signal "precious stone", designating a distinguished person, though other scholars find this reading hard to prove. What most agree on is that as a proper name, the word carried a sense of rough or tough character. The Greek form, Petros, was a masculinized coinage. Petros had not previously existed as a name. The combined form Simon Peter appears exactly 19 times in the New Testament, and after the tradition of his prominence spread through the Greek-speaking world, Petros became a popular Christian name in its own right.

• 3. Closest to the Center

  ›

  Peter is always listed first among the Twelve Apostles, in the Gospels and in the Acts of the Apostles alike. Along with James the Elder and John he formed an informal inner group, and Jesus allowed these three alone to witness three specific moments: the raising of Jairus's daughter, the Transfiguration, and the Agony in the Garden of Gethsemane. Peter is depicted repeatedly as the spokesman for the wider group, the one who steps forward to articulate what others are thinking. It was Peter who, at Caesarea Philippi, answered Jesus's question directly: "You are the Messiah, the Son of the living God." In Luke's gospel, Simon Peter owns the very boat that Jesus uses to preach to crowds pressing on him at the shore of Lake Gennesaret, and it is Peter whom Jesus instructs to lower his nets before the catch that draws Peter and his companions immediately into discipleship. In the Gospel of John, when Andrew brings his brother Simon to Jesus for the first time, Jesus looks at him and names him Cephas on the spot, without preamble. The Gospel of Mark, in particular, is traditionally held to reflect Peter's own preaching and eyewitness memory, giving that text a distinctive texture among the four.

• 4. Denial and Restoration

  ›

  All four canonical gospels record that during the Last Supper, Jesus told Peter he would deny him three times before the cockcrow. Mark specifies "before the cock crows twice". The three denials followed the arrest of Jesus in the garden. A female servant of the high priest recognized Peter and said he had been with Jesus. Peter denied it. A second challenge came at the gateway, away from the fire. He denied it again. The third denial came when bystanders took his Galilean accent as proof of his connection to Jesus. Matthew, Mark, and Luke all record the rooster crowing at that moment. Luke notes that, rather than a crowd accusing Peter the third time, it was a single individual. In Luke's gospel, Jesus had said to him beforehand: "Simon, Simon, behold, Satan hath desired to have you, that he may sift you as wheat: but I have prayed for thee, that thy faith fail not: and when thou art converted, strengthen thy brethren." In the epilogue of John's gospel, the restoration is played out with a deliberate symmetry: Peter three times affirms his love for Jesus, balancing each denial. Paul's First Epistle to the Corinthians records that the first resurrection appearance of Jesus was to Peter, a tradition that seems to have predated the written gospels. Jesuit scholar Daniel J. Harrington described Peter as an unlikely symbol of stability precisely because of this pattern: the exemplar not of perfect faith, but of the forgiven sinner.

• 5. Bridge Between Worlds

  ›

  Peter's missionary activity after the crucifixion took him from Jerusalem to Lydda, then Joppa, then Caesarea. At Joppa he received a vision permitting the eating of previously forbidden animals, which early believers interpreted as divine authorization to bring the gospel to Gentiles. When Peter met Cornelius the Centurion, he declared that "God shows no partiality". Acts 12 records that Peter was imprisoned by Herod Agrippa, who reigned from AD 42 to 44, and was freed by an angel. After that liberation, the biblical record of his movements becomes fragmentary. Methodist historian James D. G. Dunn proposed that Peter functioned as a "bridge-man" between the two most divergent currents in early Christianity: the conservative Jewish Christianity of James the Just, and the Gentile-directed mission of Paul. Paul himself affirmed that Peter held the special charge of apostle to the Jews, while Paul was apostle to the Gentiles. When Peter came to Antioch, Paul opposed him openly, accusing him of behaving inconsistently toward Gentile believers. That confrontation is recorded in the Epistle to the Galatians. The Clementine literature, written in the fourth century but believed to draw on earlier sources, describes Peter traveling with a group of twelve to sixteen followers from Caesarea Maritima to Antioch, ordaining Zacchaeus as the first bishop of Caesarea and Maro as the first bishop of Tripolis along the way. He was soon eclipsed in the leadership of the Jerusalem church by James the Just, though historians differ on whether this was a displacement or simply the consequence of Peter's commitment to missionary travel.

• 6. Rome and the Upturned Cross

  ›

  The question of Peter's presence in Rome has divided scholars for centuries. No New Testament text explicitly places him there. Paul's Epistle to the Romans, written around AD 57, greets some fifty people by name without mentioning Peter. Acts 28 describes Paul's two-year stay in Rome around AD 60-62 without naming Peter among his visitors. The case for Rome rests on the Church Fathers. Irenaeus of Lyons, writing in the second century, stated that Peter and Paul had founded the church in Rome and appointed Linus as the next bishop. Clement of Alexandria stated that Peter had preached publicly in Rome. Lactantius, writing around 318, reported that during Nero's reign Peter came to Rome and built up a faithful community. Jerome wrote that Peter arrived in Rome in the second year of the Emperor Claudius to confront a figure called Simon Magus and held the bishop's chair there for twenty-five years, through the fourteenth year of Nero. According to Jerome and Eusebius, Peter died in Rome in AD 67-68. Tertullian at the end of the second century wrote in his work Scorpiace: "The budding faith Nero first made bloody in Rome. There Peter was girded by another, since he was bound to the cross." Origen, writing in the third century, stated that Peter was crucified in Rome with his head facing downward, at his own request. The apocryphal Acts of Peter is the source for the story of Peter fleeing Rome and meeting the risen Jesus on the road. In the Latin version, Peter asks Jesus "Quo vadis?" and Jesus replies "Romam eo iterum crucifigi" - "I am going to Rome to be crucified again." Peter then turns back and accepts his martyrdom. That exchange is commemorated in an Annibale Carracci painting and in the Church of Quo Vadis near the Catacombs of Saint Callistus, which houses a stone said to bear Jesus's footprints from that encounter.

• 7. Bones, Relics, and Dispute

  ›

  In 1950, human bones were found beneath the altar of St. Peter's Basilica. The bones had been claimed as Peter's remains for some time, but in the 1960s a forensic re-examination identified them as those of a male of about 61 years of age from the first century. That finding led Pope Paul VI in 1968 to announce they were most likely the relics of the Apostle Peter. In November 2013, Pope Francis presented fragments of the relics publicly for the first time during a Mass in St. Peter's Square. In July 2019, Pope Francis transferred nine bone fragments in a bronze reliquary to Orthodox Ecumenical Patriarch Bartholomew of Constantinople, who described the gesture as "brave and bold". Francis said the decision was born "out of prayer" and was a sign of the ongoing work toward communion between the Catholic and Orthodox churches. The skull of Saint Peter is claimed to have resided in the Archbasilica of Saint John Lateran since at least the ninth century, alongside the skull of Saint Paul. The Emperor Constantine I, in the early fourth century, chose to honor Peter with a large basilica at the precise location where Roman Christians believed he was buried. The slope of Vatican Hill had to be excavated, even though flatter ground lay only slightly to the south, and an existing cemetery had to be demolished. The 2025 paper proposing that Peter and Paul's deaths may have been caused by intra-community violence rather than imperial persecution represents the latest challenge to the established account of how this fisherman from Bethsaida died.
