Saint Peter

According to New Testament accounts and patristic tradition summarized in modern reference works, Peter was born Simon bar Jonah in Bethsaida, became a fisherman in Galilee alongside his brother Andrew, and was called by Jesus to be one of the Twelve Apostles. In the gospels Jesus gives him the name Cephas (Aramaic kepha), rendered Petros in Greek, a renaming later interpreted by Christian tradition as designating a foundational role. Later church fathers and ecclesiastical historians (e.g., Irenaeus, Tertullian, Hegesippus, Clement of Alexandria, Lactantius, Eusebius) are cited in tradition as attesting that Peter lived his final years in Rome, founded the Roman church, and was martyred there (traditionally crucified upside down under Nero); these Roman and episcopal associations form the basis for later claims of apostolic succession and Petrine authority.

The supplied sources do not provide a sustained physical description. Biographical descriptors consistently recorded are that Peter was a Jewish male from Bethsaida, a fisherman by trade who worked with his brother Andrew and maintained a household (the gospels relate that Jesus healed his mother-in-law). He is treated in the literature as married or at least as head of a household. Beyond these social and occupational markers (birthplace, trade, kinship), no contemporary source details height, hair, clothing, facial features, or other bodily characteristics in the provided material.

The sources attribute to Peter human roles and social-religious functions rather than supernatural powers. He is presented in the New Testament as an apostle, preacher, and prominent eyewitness figure whose testimony shaped gospel traditions (the Gospel of Mark is traditionally associated with Peter's influence). Later tradition credits him with founding the Roman church and conferring episcopal office on successors (for example, Linus is named in patristic tradition as an early episcopal recipient). He is venerated as a saint and a model of apostolic authority; the supplied sources do not ascribe occult or non-human powers to him beyond the ordinary claim to apostolic witness and ecclesiastical primacy recorded in Christian tradition.
