Saints Peter and Paul are two of the most important figures in early Christianity. Peter, originally a fisherman, became one of Jesus' closest disciples and is often considered the first leader of the Christian Church. He is known for his role in spreading Jesus' teachings and is traditionally believed to have been martyred in Rome. Paul, originally known as Saul, was a Pharisee who initially persecuted Christians. After a dramatic conversion experience, he became a devoted follower of Christ and traveled extensively to spread the Gospel. His letters, known as the Epistles, form a significant part of the New Testament and greatly influenced Christian theology.
