Peter's original name was Simon.
Jesus later gave him the name Peter, from the Greek Petros, meaning "stone" or "rock."
John records the first meeting:
"You are Simon the son of Jonah. You shall be called Cephas" (which is translated, A Stone).
— John 1:42
Cephas is the Aramaic form corresponding to Peter.
So Peter essentially carried three forms of his name:
Simon — his Jewish name
Cephas — his Aramaic name
Peter — the Greek form used throughout much of the New Testament
Paul frequently calls him Cephas, while the Gospel writers commonly call him Peter.
This already tells us something about the world Peter lived in. Galilee was a Jewish region, but it existed within the larger Greek-speaking and Roman world. Names could therefore move between Hebrew/Aramaic and Greek forms.
John gives us an important geographical detail:
"Now Philip was from Bethsaida, the city of Andrew and Peter."
— John 1:44
So Peter and his brother Andrew were associated with Bethsaida.
Bethsaida was located near the northern end of the Sea of Galilee.
This matters because Peter was not simply a rural farmer who happened to live near a lake.
He was a Galilean fisherman whose entire economic and social world revolved around the Sea of Galilee.
Matthew describes Jesus finding Peter and Andrew:
"They were casting a net into the sea; for they were fishermen."
— Matthew 4:18
Peter therefore grew up in a working environment where fishing was not merely recreation. It was a profession.
Peter's brother was Andrew.
This is one of the most important relationships in Peter's life.
Andrew appears to have encountered Jesus before Peter.
John tells us:
"One of the two who heard John speak, and followed Him, was Andrew, Simon Peter's brother."
— John 1:40
Andrew then went looking for his brother.
"He first found his own brother Simon, and said to him, 'We have found the Messiah' (which is translated, the Christ)."
— John 1:41
And then Andrew brought Simon to Jesus.
This is an interesting detail.
Peter did not initially discover Jesus on his own. His brother brought him.
Andrew was the one who introduced Simon to Jesus.
And that becomes a recurring pattern in Andrew's life.
Andrew is often the person who brings someone else to Jesus.
Peter would eventually become one of the most prominent apostles, but Andrew was the brother who first brought him to Christ.
Peter wasn't working alone.
Luke describes a fishing partnership:
"And so also were James and John, the sons of Zebedee, who were partners with Simon."
— Luke 5:10
This is extremely important.
Peter had an established business relationship with James and John.
These four men—Peter, Andrew, James, and John—formed part of a fishing network on the Sea of Galilee.
Luke specifically says James and John were partners with Simon.
That gives us a much better picture of Peter's social world.
He wasn't an isolated fisherman.
He belonged to a working network.
He had:
a brother;
business partners;
a fishing enterprise;
connections with other families;
and eventually a close relationship with Jesus.
And these relationships continued into the ministry of Christ.
This is something modern readers sometimes overlook.
Peter was married.
Paul explicitly refers to Peter's wife:
"Do we have no right to take along a believing wife as do also the other apostles, the brothers of the Lord, and Cephas?"
— 1 Corinthians 9:5
Paul uses Cephas, clearly referring to Peter.
So Peter was not a lifelong celibate bachelor.
He was a married man when Jesus called him.
That becomes even more interesting because Peter's family appears in the Gospels.
Matthew tells us:
"Now when Jesus had come into Peter's house, He saw his wife's mother lying sick with a fever."
— Matthew 8:14
Mark gives the same account:
"But Simon's wife's mother lay sick with a fever, and they told Him about her at once."
— Mark 1:30
This gives us a fascinating glimpse into Peter's household.
Peter had a wife.
His mother-in-law was living in the household or at least staying there at the time.
And Jesus entered Peter's house.
This is important because it tells us that Peter was not merely following Jesus as an unattached young man with nothing to lose.
He had a household.
He had family responsibilities.
He had an occupation.
He had a business partnership.
And yet he eventually left those things to follow Jesus.
Although Peter was from Bethsaida, the Gospels show him living in or having a household in Capernaum.
Matthew says:
"Now when Jesus had come into Peter's house..."
— Matthew 8:14
Mark likewise refers to Peter's house.
Capernaum became one of the major centers of Jesus' Galilean ministry.
The Gospel accounts suggest that Peter's home became something of a base of operations for Jesus and His disciples.
Jesus repeatedly returned to Capernaum.
And Peter's household became part of that ministry environment.
Peter wasn't presented as a member of Jerusalem's religious elite.
He was a fisherman.
That becomes important when we later see him standing before the Jewish authorities in Jerusalem.
Acts says:
"Now when they saw the boldness of Peter and John, and perceived that they were uneducated and untrained men, they marveled."
— Acts 4:13
The Greek wording does not necessarily mean Peter was stupid or illiterate.
It indicates that they were not formally trained in the recognized rabbinical system.
These were working-class Galileans, not graduates of Jerusalem's elite theological schools.
And yet these men were standing before the educated religious authorities and speaking boldly about Jesus.
That contrast is one of the great themes of Peter's story.
Peter was not a pagan who suddenly discovered the God of Israel.
He was Jewish.
He knew the Scriptures.
He participated in Jewish religious life.
We see this particularly clearly when Jesus and Peter encounter the temple-tax issue.
Matthew records:
"When they had come to Capernaum, those who received the temple tax came to Peter and said, 'Does your Teacher not pay the temple tax?'"
— Matthew 17:24
Notice something fascinating:
They approached Peter.
That suggests Peter was known within the community.
Jesus then used the occasion to teach Peter about His identity and authority.
Peter was therefore operating within the religious world of first-century Judaism.
Peter also appears to have been connected to the movement surrounding John the Baptist, at least indirectly through his brother Andrew.
John's Gospel says Andrew was originally one of the two disciples associated with John the Baptist who began following Jesus.
"Again, the next day, John stood with two of his disciples."
— John 1:35
Andrew was one of them.
He then went to find Simon.
So Peter entered Jesus' circle through a network that was already connected to the ministry of John the Baptist.
This is significant.
Peter didn't simply wake up one morning and decide to become a disciple of Jesus.
There was already a spiritual movement developing among Jews who were looking for the coming Messiah.
Andrew was part of that movement.
Then Andrew brought Peter.
This is where Peter becomes especially interesting.
Peter was not timid.
He was impulsive.
He was outspoken.
He frequently said what everyone else was thinking.
Sometimes that was wonderful.
Sometimes it got him into serious trouble.
When Jesus asked the disciples:
"But who do you say that I am?"
Peter immediately answered:
"You are the Christ, the Son of the living God."
— Matthew 16:15–16
That is one of the greatest declarations of faith in the Gospels.
But shortly afterward, Peter rebuked Jesus when Jesus explained that He would suffer and die.
Jesus responded:
"Get behind Me, Satan!"
— Matthew 16:23
Peter could go from great spiritual insight to serious spiritual error remarkably quickly.
That is Peter.
When Jesus was arrested, Peter did not simply run away immediately.
John tells us:
"Then Simon Peter, having a sword, drew it and struck the high priest's servant, and cut off his right ear."
— John 18:10
Peter was willing to physically fight for Jesus.
His courage was real.
But his understanding was incomplete.
Jesus commanded him:
"Put your sword into the sheath."
— John 18:11
Peter wanted to defend Jesus with the weapons of earthly warfare.
Jesus was going to defeat His enemies through obedience to the Father and the cross.
Peter had courage.
He simply hadn't yet learned how Jesus wanted that courage to be used.
Peter, James, and John occupied a unique position among the Twelve.
Jesus repeatedly took these three with Him when the others were left behind.
They were present at the raising of Jairus' daughter.
They accompanied Jesus to the Mount of Transfiguration.
They were taken farther into Gethsemane.
This means Peter had an extraordinary level of access to Jesus.
He saw things that most of the Twelve did not see.
He heard conversations that others did not hear.
He witnessed miracles that few others witnessed.
He was being prepared for leadership.
This may be the most important part of his character study.
Peter confidently told Jesus:
"Even if all are made to stumble, yet I will not be."
— Mark 14:29
He meant it.
Peter genuinely believed he would remain loyal.
But Jesus knew Peter better than Peter knew himself.
Jesus said:
"Before the rooster crows twice, you will deny Me three times."
— Mark 14:30
And Peter did.
Three times.
After the third denial, Peter remembered Jesus' words.
Mark tells us:
"And when he thought about it, he wept."
— Mark 14:72
This is not the end of Peter's story.
It is the beginning of his transformation.
After the resurrection, Jesus deliberately restored Peter.
In John 21, Jesus asked Peter three times:
"Simon, son of Jonah, do you love Me?"
Three denials.
Three questions.
Three opportunities for Peter to reaffirm his love.
Jesus then told him:
"Feed My sheep."
— John 21:17
This is one of the most beautiful moments in Peter's life.
Jesus did not pretend Peter had never failed.
He did not minimize the denial.
Instead, Jesus restored the broken disciple and entrusted him with responsibility.
The man who once denied Jesus in fear would eventually stand publicly and proclaim Jesus before thousands.
The transformation becomes obvious in Acts.
The same Peter who had been afraid of a servant girl's questions now stood before thousands of people and proclaimed Christ.
Acts 2 records Peter preaching at Pentecost.
He explained the death and resurrection of Jesus and called Israel to repentance.
Approximately three thousand people responded to the message.
The fisherman from Galilee had become a public preacher of the resurrection.
And the authorities noticed.
Peter appears repeatedly in the opening chapters of Acts.
He preached.
He healed.
He confronted opposition.
He testified before the Sanhedrin.
He refused to stop preaching Christ.
When commanded not to speak in Jesus' name, Peter and John answered:
"We ought to obey God rather than men."
— Acts 5:29
That is the same man who had once been terrified by a servant girl's question.
Something had changed.
Peter's courage was no longer merely personality.
His courage had become faithfulness to Christ.
Peter's life gives us a remarkable picture of spiritual growth.
He began as Simon.
He was a fisherman.
He was married.
He had a brother.
He had business partners.
He had a household.
He was connected to the Jewish religious world.
He was introduced to Jesus through his brother Andrew.
He became one of Jesus' closest disciples.
He saw extraordinary miracles.
He confessed Jesus as the Messiah.
He misunderstood the cross.
He tried to defend Jesus with a sword.
He denied Jesus three times.
He wept bitterly.
Jesus restored him.
Then Peter became one of the principal witnesses of the resurrection and one of the leading voices of the early church.
The Peter we meet in Acts is not simply the same Peter with more confidence.
He has been broken, restored, humbled, and transformed.
And that may be the central lesson of his life:
God did not throw Peter away because Peter failed.
Jesus knew exactly what Peter would become after his failure.
Jesus told him before the denial:
"And when you have returned to Me, strengthen your brethren."
— Luke 22:32
Peter's failure was not the end of his usefulness.
Christ's grace was greater than Peter's failure.
