It would depend upon your question. In the Book of Mark, Chapter 8, when Jesus says to His disciples, "Who do you say that I am?" Peter answers, "Thou art the Christ" (Mark 8:29).
When Peter said to Jesus, "I shall never deny you Master." Jesus, told Peter, "Before the cock crows twice, you will deny me three times." This was during the Last Supper.
Before the cock crowed twice, on the day of the Crucifixion, Peter denied three times that he knew Jesus. Peter later wept in repentance (Mark 14:72).
Jesus asked his disciples, "But who do you say that I am?" Peter answered, "You are the Christ." Peter, according to this passage, believed that Jesus was the Messiah.
Jesus said that Peter would deny Him three times before the cock crows and Peter replied that he would never deny Him. I am pretty sure that is how it went.
Peter denied Jesus three times.
Peter baptised jesus. (Matthew 16:18 -- "And I say to thee: thou art Peter, and upon this rock I will build my Church..")
It was Peter. Jesus asked him who Peter thought He was. Peter answered that Jesus was the only Son of the living God. Then Jesus told him (Peter), that he would be the foundation of the new church (Christianity).
Peter proudly denied that he would ever deny Jesus , but he denied Jesus three times just as Jesus said he would do. And he was a favourite disciple.
here we can say it is Simon Peter.
Jesus told Peter that he was his rock and on him Jesus would build his church. Peter was the first Pope.
Peter denied Jesus three times. Jesus foretold that Peter would deny him three times in Mark 14:30, and he did.
after Jesus had seen Peter and his brother at the fish
Off hand, I would say that of the twelve disciples, John and Peter were His two closest friends. John, in his gospel called himself "the disciple whom Jesus loved". Peter was the one who after he had denied Jesus three times, was asked by Jesus: "Peter do you love me?" three times.
While Jesus saw Peter and his brother Andrew along with James and John sll were fishing or repairing their fishing nets. Jesus told Peter , whose real name was Simon to follow me , and I will make you fishers of men.
