Later accounts expand on the brief Biblical mention of his visit to Antioch. The Liber Pontificalis (9th century) mentions Peter as having served as bishop of Antioch for seven years and having potentially left his family in the Greek city before his journey to Rome. Claims of direct blood lineage from Simon Peter among the old population of Antioch existed in the 1st century and continue to exist today, notably by certain Semaan families of modern-day Syria and Lebanon. Historians have furnished other evidence of Peter’s sojourn in Antioch. Subsequent tradition held that Peter had been the first Patriarch of Antioch.
Peter might have visited Corinth, as a party of “Cephas” existed there.
Eusebius of Caesarea (Eusebius Caesariensis, ca 260-ca 340), in his “Historia Ecclesiastica”, while naming some of the Seventy Disciples of Jesus, says:
“… and the history by Clement (of Alexandria, c.150 – c. 215), in the fifth (chapter) of Hypotyposeis; in which Cefas, the one mentioned by Paul (in the citation): «when Cefas came to Antioch, I confronted him face to face» (Galatians 2:11), it is said he was one of the Seventy Disciples, having the same name with Peter the Apostle“.
Non-canonical sayings of Peter
Two sayings are attributed to Peter in the gnostic Gospel of Thomas. In the first, Peter compares Jesus to a “just messenger.” In the second, Peter asks Jesus to “make Mary leave us, for females don’t deserve life.”
In the Apocalypse of Peter, Peter holds a dialogue with Jesus about the parable of the fig tree and the fate of sinners.
In the Gospel of Mary, whose text is largely fragmented, Peter appears to be jealous of “Mary” (probably Mary Magdalene). He says to the other disciples, “Did He really speak privately with a woman and not openly to us? Are we to turn about and all listen to her? Did He prefer her to us?” In reply to this, Levi says “Peter, you have always been hot tempered.”
Other noncanonical texts that attribute sayings to Peter include the Secret Book of James and the Acts of Peter.
