The Apostle Peter, also known as Saint Peter (from the Greek Petros, meaning "rock"), Shimon "Keipha" Ben-Yonah/Bar-Yonah, Simon Peter, Cephas an Keipha (Keipha and Cephas also mean rock)—original name Shimon or Simeon (Hebrew: שמעון) ( (Acts 15:14)—was one of the Twelve Apostles whom Jesus chose as his original disciples. His life is prominently featured in the New Testament Gospels and the Acts of the Apostles. Peter was a Galilean fisherman assigned a leadership role by Jesus (Matthew 16:18; John 21:15–16). Many within the early Church, such as St. Irenaeus, assert his primacy among the apostles.
