Six key facts about Peter, drawn from biblical and historical sources, show the arc of his life:

Label Value
Full name Simon Peter
Birthplace Bethsaida, Galilee (New Advent Catholic Encyclopedia)
Occupation Fisherman (Bart Ehrman, historian)
Biblical books Gospels, Acts, 1–2 Peter
Feast day June 29 (with Paul) (Vatican News)
Symbol Keys, rooster, upside-down cross

The pattern: every attribute is anchored either in the New Testament or in ancient Christian tradition that has been passed down through the church.

What is Saint Peter known for?

Role as leader of the Apostles

Peter acts as the spokesman for the Twelve in every Gospel. He is the first disciple Jesus calls, the one who tries to walk on water, and the one who denies him three times—and then is restored. The Vatican News (the Holy See’s official news service) notes that Peter is the most frequently mentioned apostle in the Gospels.

First Pope in Catholic tradition

Jesus’ words in Matthew 16:18—“You are Peter, and upon this rock I will build my church”—are understood by Catholic Answers (apologetics organization) as the founding moment of the papacy. The Catholic Telegraph (U.S. Catholic newspaper) calls this “the most important verse in the New Testament for Catholic ecclesiology.” Not all Christian traditions agree: GotQuestions.org (evangelical perspective) argues that the New Testament does not show Peter exercising papal supremacy.

Symbol of the keys

Peter is routinely depicted holding two keys, referencing Jesus’ promise in Matthew 16:19: “I will give you the keys of the kingdom of heaven.” This symbol appears in papal heraldry and on the Vatican coat of arms. The Vatican News explains that the keys represent “the authority to bind and loose on earth and in heaven.”

Bottom line: Saint Peter is known as the leader of the apostles, the first pope in Catholic tradition, and the keeper of the keys—all rooted in the New Testament and early church writings, though Protestant traditions interpret these roles differently.

Why did Jesus pick Saint Peter?

Peter’s confession of faith

In the Gospel of Matthew, when Jesus asks his disciples who they believe he is, Peter answers: “You are the Christ, the Son of the living God.” Jesus responds by declaring him “Peter” and saying the church will be built upon that rock. The Catholic Telegraph cites this confession as the reason Jesus gave Peter special authority.

His impulsive and passionate nature

Peter’s personality is anything but reserved. He steps out of a boat to walk on water (Matthew 14:29), cuts off a servant’s ear at Jesus’ arrest (John 18:10), and later weeps bitterly after denying his master. Bart Ehrman (historian of early Christianity) describes Peter as “the most human and relatable of the apostles” precisely because of his impulsive mistakes and later restoration.

Biblical basis in Matthew 16:18

Jesus chose Peter not for flawless behavior but for his foundational confession. The New Advent Catholic Encyclopedia interprets Matthew 16:18-19 as Jesus designating Peter as the earthly foundation of the church. The same passage is disputed among scholars, but the historical consensus is that it reflects an early tradition of Peter’s unique leadership role.

The paradox

The same man who denied Jesus three times became the anchor of the early church. That contrast is why Peter’s story resonates so deeply across denominations.

What happened to Peter after Jesus died?

Peter’s role in the early church

After the resurrection, Peter re-emerges as the leader of the twelve. He preaches the sermon at Pentecost that leads to 3,000 baptisms (Acts 2:41). He heals a lame man at the Temple (Acts 3) and appears before the Jewish council. The Vatican News notes that “Peter’s primacy in the early chapters of Acts is beyond doubt.”

His missionary journeys

Paul mentions in Galatians 2:9 that Peter, James, and John were recognized as “pillars” of the church in Jerusalem (Wikipedia). Peter traveled to Samaria, Lydda, Joppa, and Caesarea. The New Advent Catholic Encyclopedia states that “it is an indisputably established historical fact” that Peter later labored in Rome during the last portion of his life.

Martyrdom in Rome

Christian tradition consistently holds that Peter was martyred in Rome under Emperor Nero. EWTN (Catholic network) gives AD 67 as the traditional date. Vatican News adds that the feast of Saints Peter and Paul on June 29 commemorates their martyrdom. National Geographic reports the tradition that he was crucified upside down at his own request.

Bottom line: After Jesus’ death, Peter led the Jerusalem church, took the gospel to the Gentile world, and ultimately died in Rome during Nero’s persecution—a journey that shaped Christianity’s early expansion.

Why was Saint Peter put to death?

Persecution under Emperor Nero

After the Great Fire of Rome in AD 64, Nero blamed Christians and launched a brutal crackdown. Wikipedia notes that Peter was among those executed during this period. EWTN links Peter’s death directly to Nero’s persecution, citing the traditional date of AD 67.

Refusal to renounce faith

Early church historians such as Eusebius record that Peter refused to stop preaching about Jesus even under threat of death. The New Advent Catholic Encyclopedia says Peter’s death was a direct result of his unwavering public witness.

Crucifixion details

The most widely repeated account—found in the apocryphal Acts of Peter and echoed by The Catholic Telegraph—states that Peter asked to be crucified upside down because he felt unworthy to die in the same manner as Jesus. National Geographic confirms that this tradition is widely accepted in Catholic and Orthodox circles. His burial site on Vatican Hill is now under St. Peter’s Basilica.

The catch

No contemporary Roman record of Peter’s execution survives. The earliest written accounts come from the late second century, so the details rely heavily on church tradition rather than secular corroboration.

What are 5 interesting facts about Peter as a person?

His original name was Simon

Jesus renamed Simon to Peter (Greek: Petros, meaning “rock”). The Vatican News explains the renaming as a sign of his new mission. His original name appears throughout the Gospels before the name change.

He was a fisherman

Peter worked as a professional fisherman on the Sea of Galilee alongside his brother Andrew before being called. Bart Ehrman (historian) notes that this was a modest but stable livelihood, and Peter likely owned a house in Capernaum (Mark 1:29).

He walked on water

In Matthew 14:22-33, Peter briefly walks on water toward Jesus before sinking in fear. This story is unique to Matthew’s Gospel and is often cited to illustrate Peter’s combination of boldness and doubt.

He denied Jesus three times

During the night of Jesus’ trial, Peter denied knowing him three times before the rooster crowed—just as Jesus had predicted. The Vatican News treats the denial as a pivotal moment that makes Peter’s restoration all the more powerful.

He was married

The Bible mentions Peter’s mother-in-law in Matthew 8:14-15, confirming he was married. Early Christian writers such as Clement of Alexandria also reference Peter’s wife. Her fate is not recorded, but tradition holds she may have accompanied him. A related internal resource is Pope Leo XIV: Biography of the First American Pope, which explores the modern papacy’s lineage.

“You are Peter, and upon this rock I will build my church, and the gates of Hades will not prevail against it.”

“James, Cephas [Peter] and John, those esteemed as pillars, gave me and Barnabas the right hand of fellowship.”

— Paul (Galatians 2:9), acknowledging Peter’s leadership (Wikipedia)

“Peter, the first of the apostles, was condemned to death and crucified, and he requested to be fastened to the cross head downwards.”

— Eusebius, Church History (c. 4th century), as cited by National Geographic

Summary: The legacy of Saint Peter

Peter’s story—from a Galilean fisherman to the foundational leader of the Christian church—remains one of history’s most dramatic transformations. For Catholics, he is the first pope, the rock upon which the church is built. For many Protestants, he is a flawed but faithful disciple whose weaknesses make him relatable. The archaeological evidence under St. Peter’s Basilica, explored in National Geographic, suggests that the early Roman Christian community venerated a tomb there from very early times. For anyone interested in the origins of Christianity, the figure of Peter is inescapable. The choice for modern readers is not whether to believe, but how to interpret the layers of history, tradition, and faith that surround this extraordinary apostle.
