Saint Peter the Apostle.

The divinely-blessed Peter was from Bethsaida of Galilee. He was the son of Jonas and the brother of Andrew the First-called. In the synoptic gospels, Peter (then Simon) was a fisherman along with his brother Andrew and the sons of Zebedee, James and John. His early life was ordinary, rooted in the daily labour of fishing the waters of Galilee. However, Simon's older brother, Andrew, was already a disciple of John the Baptist before both brothers encountered Jesus.

In Matthew and Mark, Jesus called Simon and his brother Andrew to be "fishers of men". This calling marked a radical transformation. From that moment, Simon left his nets to follow the Teacher, becoming one of Jesus' most intimate companions and a witness to the central events of His ministry—the Transfiguration, the Last Supper, the Crucifixion, and the Resurrection.

According to Origen (184–253) and Eusebius, Peter "after having first founded the church at Antioch, went away to Rome preaching the Gospel, and he also, after [presiding over] the church in Antioch, presided over that of Rome until his death". After presiding over the church in Antioch for a while, Peter would have been succeeded by Evodius and thereafter by Ignatius, who was a disciple of John the Apostle. In Jerusalem, Peter exercised leadership among the apostles and became the primary voice of the early community, performing miracles and proclaiming the Gospel with boldness.

After Pentecost, Peter played a crucial role in the establishment of the early Church in Jerusalem, delivering powerful sermons and performing miracles. His interactions with Gentiles marked a significant shift in early Christian outreach, highlighting the movement's expansion beyond its Jewish roots. The Eastern Orthodox Church recognizes Peter as a chief apostle and foundational bishop, though without the papal authority claimed by Roman tradition.

After an extensive ministry in Jerusalem, Judea, Samaria, Syrian Antioch, and beyond, he traveled to Rome, where he was killed at some point between AD 64 and 67, during the reign of Nero (54–68). Jerome (327–420) wrote that "at Nero's hands Peter received the crown of martyrdom being nailed to the cross with his head towards the ground and his feet raised on high, asserting that he was unworthy to be crucified in the same manner as his Lord".

According to the writings of Church Fathers such as Origen and Jerome, Peter requested that his cross be inverted, declaring himself unworthy to imitate the death of Jesus. This detail came from the apocryphal Acts of Peter, and Roman soldiers, with no concern for religious symbolism, reportedly granted the request, which they simply interpreted as a further act of humiliation. His martyrdom under Nero affirmed the testimony of his faith and sealed with his blood the Gospel he had proclaimed throughout his life.

His feast is celebrated on June 29 along with the Apostle Paul. The Eastern Orthodox Church honors Peter as a principal apostle and pillar of the Church, commemorating him together with Paul, the Apostle to the Gentiles. The Orthodox Church has a beautiful presentation of the importance and prominence of the Apostles Peter and Paul with the icon that shows both Apostles standing together holding an image of the Church. Peter's example of transformed weakness—from threefold denial to rock-like steadfastness—remains a powerful witness to the redemptive grace of Christ.

Throughout the Orthodox world, churches and monasteries bear his name, and his intercession is sought by the faithful. They were exposed to the veneration of the faithful during the solemn Divine Liturgy presided by His All-Holiness Ecumenical Patriarch Bartholomew on the occasion of the feast of the Holy Twelve Apostles, on 30 June, 2019, celebrated in the Church of the Holy Apostles in Feriköy, in the neighborhood of Şişli in Istanbul. After that, the reliquary will be kept at the Ecumenical Patriarchate. His memory endures as a beacon of apostolic faith and pastoral love.

Peter the Apostle stands as one of the most prominent figures in early Christianity and remains central to Orthodox tradition. The holy, glorious and all-laudable Apostle Peter is the leader of the twelve apostles of Jesus Christ. Originally named Simon, a Jewish fisherman born in Bethsaida, he was the son of a man named Jonah or John. He was the brother of Andrew the First-called.

He was renamed Peter by the Lord Jesus Christ himself, who looked at him and said, "Thou art Simon the son of Jonas; thou shalt be called Cephas (which is by interpretation, Peter)" (John 1:42). This new name held profound theological meaning: Peter (Greek Petros) means "rock," and Jesus used this name to signal Peter's foundational role in the Church.

Throughout Jesus' earthly ministry, Peter demonstrated both fervent devotion and human weakness. On being raised by the Lord to the dignity of an Apostle and becoming inseparable from him as his zealous disciple, he followed him from the beginning of his preaching of salvation up until the very Passion, when, in the court of Caiaphas the high priest, he denied Him thrice because of his fear of the Jews and of the danger at hand. Yet after the Resurrection, Christ lovingly restored him and entrusted him with pastoral authority over the Church.

After the Resurrection of Christ and the descent of the Holy Spirit, he preached in Judea, Antioch, and certain parts of Asia, and finally came to Rome, where he was crucified upside down by Nero, and thus he ascended to the eternal habitations about the year 66 or 68, leaving two Catholic (General) Epistles to the Church of Christ. Both Apostles, being chosen by our Lord, were instrumental in the establishment and growth of the early Church through their boldness, spiritual strength, and wisdom. Thus they are recognized as "pillars" of the Church, having offered all even unto death for the sake of the Gospel of Christ.
