In the New Testament, Peter appears repeatedly and prominently in all four gospels as well as the Acts of the Apostles. He is the brother of Saint Andrew, and both brothers were fishermen. The Gospel of Mark in particular was traditionally thought to show the influence of Peter's preaching and eyewitness memories. He is also mentioned, under either the name Peter or Cephas, in Paul's First Letter to the Corinthians and the Epistle to the Galatians. The New Testament also includes two general epistles, First Peter and Second Peter, that are traditionally attributed to him, but modern scholarship generally rejects the Petrine authorship of both.[8]
Outside of the New Testament, several apocryphal books were later attributed to him, in particular the Acts of Peter, Gospel of Peter, Preaching of Peter, Apocalypse of Peter, and Judgment of Peter, although scholars believe these works to be pseudoepigrapha.[9][10][11]
