Peter was the son of John and was from the Bethsaida in the province of Gailile. He was born in the year 4 AD under the name Simon. His brother Andrew was also an apostle. He was originally a fisherman, but then became one of twelve apostles chosen by Jesus from his first disciples. He was a great leader and was with Jesus during events witnessed by only a few apostles, such as the Transfiguration.
"Blessed are you, Simon son of Jonah, for this was not revealed to you by flesh and blood, but by my Father in heaven. And I tell you that you are the rock, and on this rock I will build my church, and the gates of Hades will not overcome it. I will give you the keys of the kingdom of heaven; whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven." This is one of the most important moments between Peter and Jesus, because this shows that he will become a great leader to the Catholic Church. This becomes true when Peter is the first Pope. Peter wrote the Epistles in the New Testament.
Peter was crucified in Rome , and it is said that he was crucified upside down at his own request. He asked if this because he thought he was unworthy to be crucified in the same way as Jesus. Tradition holds that he was crucified at the site of the Clementine Chapel. His remains are at Peter's Basilica in Vatican City.
