Who Was Peter?

Peter, originally named Simon, was a Galilean fisherman who became one of Jesus's twelve apostles and a leading figure in the early church. His story runs through the Gospels, especially Matthew 16 and John 21, and through Acts 1 to 12, and two New Testament letters bear his name.

What Peter is known for

Peter’s life in order

  1. Brought to Jesus

    John 1:40–42

    Andrew, a follower of John the Baptist, tells his brother Simon that he has found the Messiah and brings him to Jesus. Jesus looks at Simon and gives him a new name, Cephas, which is translated Peter.

  2. Fishers of people

    Luke 5:1–11

    After a night of catching nothing, Simon lets down his nets at Jesus's word and hauls in so many fish that the boats begin to sink. Overwhelmed, he falls at Jesus's knees, and then leaves everything to follow him.

  3. Walking on the water

    Matthew 14:22–33

    When Jesus comes to the disciples across the stormy lake, Peter asks to come to him and steps out of the boat. He begins to sink when he notices the wind, and Jesus catches him.

  4. The great confession

    Matthew 16:13–20

    Asked who the disciples think he is, Peter answers that Jesus is the Messiah, the Son of the living God. Jesus blesses him and speaks of building his church on this rock, words that traditions have read in different ways.

  5. On the mountain

    Matthew 17:1–8

    Peter, James and John see Jesus transfigured, with Moses and Elijah beside him. Peter offers to build three shelters, but a voice from a bright cloud interrupts him.

  6. Three denials

    Luke 22:54–62

    After Jesus's arrest, Peter follows at a distance into the high priest's courtyard. Three times he denies knowing Jesus, and when the rooster crows he remembers Jesus's warning and weeps bitterly.

  7. Restored by the lake

    John 21:15–19

    After the resurrection, Jesus meets the disciples by the Sea of Galilee and three times asks Peter whether he loves him. Each time he gives Peter the task of caring for his followers, and hints at the kind of death Peter will die.

  8. Preaching at Pentecost

    Acts 2:14–41

    When the Holy Spirit comes on the believers in Jerusalem, Peter stands up and explains what is happening to the crowd. Acts records that about three thousand people were baptized that day.

  9. The vision and Cornelius

    Acts 10:1–48

    Through a vision of clean and unclean animals, Peter comes to understand that God welcomes people of every nation. He visits the home of Cornelius, a Roman centurion, and baptizes the first Gentile household described in Acts.

What does the name Peter mean?

His given name was Simon, and he is sometimes called Simon son of John or Simon son of Jonah. Jesus gave him the name Cephas, an Aramaic word meaning rock, translated into Greek as Petros, from which Peter comes (John 1:42).

Jesus plays on this name in Matthew 16:18. The New Testament uses Simon, Peter, Simon Peter and Cephas for the same man; Paul often calls him Cephas.

What Peter’s story shows

Failure is not the end

Peter's denial is one of the most painful moments in the Gospels, yet it is followed by restoration and a new task. His story has comforted many people who feel they have let others down.

Bold and human at once

Peter speaks first, acts quickly and sometimes gets it wrong. The Gospels do not polish his image, which makes his growth easier to recognize.

Learning to widen the circle

Peter's visit to Cornelius shows a person changing long-held assumptions about who belongs. Even later, Galatians 2 shows he still had to work this out in practice.

Leadership as care

The charge Peter receives in John 21 is about looking after others. His first letter returns to this theme when it urges leaders to serve willingly rather than for gain.

How traditions view Peter

The Catholic Church regards Peter as the first bishop of Rome and the first pope, reading Matthew 16:18-19 as giving him a unique role passed on to his successors. Eastern Orthodox churches honor Peter as the foremost of the apostles but understand his primacy and its succession differently.

Many Protestant traditions read the rock of Matthew 16:18 as Peter's confession of faith, or as Peter in his role as a founding apostle, without a line of succession. All of these traditions agree that Peter was a central leader of the earliest church.

Did Peter write 1 and 2 Peter?

Both letters open with Peter's name, and Christian tradition has long accepted them as his. Many modern scholars question whether Peter wrote 2 Peter, and some also question 1 Peter, noting its polished Greek; others point out that 1 Peter 5:12 mentions Silvanus helping with the writing.

How did Peter die?

The New Testament does not describe Peter's death, though John 21:18-19 points toward it. Early Christian tradition holds that he was crucified in Rome under Emperor Nero; the detail that he was crucified upside down comes from later tradition.

Frequently asked questions

Who was Peter in the Bible?

Peter was a fisherman from Galilee, originally called Simon, who became one of Jesus's closest disciples. He is listed first in every list of the twelve apostles, denied Jesus during his trial, and later became a leading preacher in the early church in Jerusalem.

Why did Jesus call Simon "Peter"?

Jesus gave Simon the name Cephas, Aramaic for rock, which in Greek is Petros (John 1:42). In Matthew 16:18 Jesus connects the name with building his church, a verse that different Christian traditions interpret in different ways.

How many times did Peter deny Jesus?

Three times. All four Gospels record that Peter denied knowing Jesus while Jesus was being questioned, as Jesus had predicted. Luke 22:61-62 adds that Jesus turned and looked at Peter, who went out and wept.

Was Peter the first pope?

The Catholic Church teaches that Peter was the first bishop of Rome and so the first pope. The New Testament does not use that title, and Orthodox and Protestant Christians understand Peter's leadership differently, though all recognize his importance in the early church.

Was Peter married?

Yes. The Gospels mention that Jesus healed Peter's mother-in-law in Capernaum (Mark 1:29-31), and Paul notes in 1 Corinthians 9:5 that Cephas took a believing wife with him on his travels. Her name is not recorded.

What happened to Peter after Acts?

Peter appears in Acts until the council in Jerusalem in Acts 15, and Paul mentions meeting him in Galatians 1 and 2. After that the Bible is silent; early tradition places him in Rome, where he is said to have been martyred under Nero.
