Saint Peter was a first-century fisherman from Bethsaida who became one of the Twelve Apostles of Jesus. Also known as Simon or Cephas, he emerged as a central leader within the early Christian movement. According to various traditions, he served as the first bishop of Antioch and the first bishop of Rome, making him a foundational figure for several major Christian denominations. He is traditionally believed to have been martyred in Rome during the reign of Emperor Nero.
