Peter the Apostle: names, birthday and feast day

When was Saint Peter born?

A precise birthday is not established by the Gospel accounts discussed in Benedict XVI's biography of Peter. They place him in the first-century world of Jesus and identify his home town and work, but do not supply a birth date. June 29 is his liturgical celebration with Paul; it should not be copied into a biography as his date of birth.

Are Simon, Cephas and Peter the same person?

Yes, in these accounts they refer to the same apostle. Simon was his earlier name; Cephas is the Aramaic name given by Jesus, rendered Peter in Greek and associated with rock. Benedict XVI identifies him as Andrew's brother and a fisherman from Bethsaida. Simon the Zealot, another member of the Twelve, is a different apostle.

When is Saint Peter's feast day?

June 29 is the Solemnity of Saints Peter and Paul, Apostles, in the Roman Catholic calendar. It is a shared celebration, even though Peter and Paul have distinct life stories. In 2026, June 29 falls on a Monday. This is a date for the Church's worship, not evidence of Peter's historical birthday.

Biography

Peter, originally called Simon, was a fisherman whom Jesus called to discipleship with his brother Andrew. The Gospels place him at important moments in Jesus’ ministry, including the confession of Jesus as Messiah and the Transfiguration. They also preserve his failure: he denied knowing Jesus during the events leading to the Crucifixion.

The change from Simon to Peter is connected with his commission in Matthew 16, where the image of the keys expresses responsibility within the community. This is why keys became his familiar identifying symbol in Christian art and why Catholic tradition associates him with the foundations of the papacy.

His portrayal is not one of effortless certainty. Questions, misunderstanding, loyalty, and repentance all appear in the Gospel narratives. Read together, they explain a leadership grounded in an encounter with mercy rather than an account that conceals personal failure.

His calling took place within a working household. The Gospels associate him with Bethsaida, with fishing on the Sea of Galilee, and with a home at Capernaum where Jesus healed his mother-in-law. These details situate him as a married Jewish man with family and livelihood, not as someone whose life began only when he became an apostle. Discipleship changed the direction of an already established life.

Benedict XVI’s reflection on Peter emphasizes the mixture of determination and fear in his character. The same disciple who speaks boldly must learn that Jesus’ mission cannot be controlled by his own expectations. His importance for Christian readers includes that process of learning: faithfulness grows through correction and repentance. The Gospel portrait leaves his weaknesses visible alongside his distinctive responsibility, allowing his story to speak to people conscious of their own failures.

After the Resurrection, John’s Gospel describes Jesus entrusting Peter with care for his followers. Acts presents him as a prominent witness in the early Church. Christian tradition associates his final ministry and martyrdom with Rome. His shared feast with Paul on June 29 recalls two distinct lives that helped shape the Church’s beginnings.

Context & contribution

Why receiving service was difficult

Peter’s resistance when Jesus washes his feet adds a distinctive difficulty to his Gospel portrait. He is not only reluctant to suffer with Jesus; he must also learn to accept service from him. The episode challenges Peter’s expectations about what authority should look like.

Read beside the later charge to tend Christ’s followers, this scene gives pastoral responsibility a concrete shape. Leadership involves care received before care offered. Peter’s questions and objections remain in the narrative, allowing readers to see formation as a process rather than imagining that his commission removed the need to learn.
