St Paul was born with the Jewish name Saul in Tarsus, the principal city of Cilicia in the eastern Roman Empire. His exact birth year is unknown, although a date around AD 8 is a reasonable reconstruction from the age descriptions preserved in Acts and Philemon. Paul identified himself as an Israelite from the tribe of Benjamin, circumcised on the eighth day and formed as a Pharisee. Acts additionally presents him as a Roman citizen from birth and as a student educated in Jerusalem under the respected teacher Gamaliel.
Tarsus stood at the meeting point of Jewish, Greek and Roman cultures. Paul belonged to the Jewish diaspora and wrote in Greek, while his Roman citizenship later gave him significant legal protections. Acts describes his trade with the Greek word skēnopoios, traditionally translated as tentmaker. This may have involved working with leather, linen or the coarse goat-hair material used for tents and mats. Paul continued supporting himself through manual work during parts of his missionary ministry.
Paul’s Jewish name was Saul, while Paul was his Roman name. The New Testament does not say that Jesus changed his name during his conversion. Acts initially calls him Saul and later introduces him as “Saul, also known as Paul” when his mission among Gentiles becomes prominent. He therefore probably possessed both names before becoming a Christian, as was common among Jews living within the wider Greco-Roman world.
Paul was initially a determined opponent of the early Christian movement. He believed that the proclamation of Jesus as the crucified and risen Messiah threatened the faithfulness of Israel’s ancestral traditions. Acts first mentions Saul at the martyrdom of St Stephen, where the witnesses placed their cloaks at his feet. Saul approved of Stephen’s death and subsequently entered homes, arrested Christian men and women and attempted to destroy the Church. Paul later acknowledged this persecution repeatedly in his own letters.
While travelling towards Damascus with authority to arrest followers of Jesus, Paul experienced the decisive event of his life. Acts recounts that a light from heaven surrounded him, that he fell to the ground and that he heard the risen Jesus ask, “Saul, Saul, why are you persecuting me?” The identification of Christ with his persecuted people became fundamental to Paul’s later understanding of the Church as the Body of Christ.
Acts describes Paul as being blinded and led into Damascus, where he fasted for three days. The Lord sent a Christian named Ananias to him. Despite knowing Saul’s reputation, Ananias addressed him as a brother, laid hands upon him and announced that God had chosen him as a witness. Paul regained his sight, received Baptism and began proclaiming that Jesus is the Son of God. None of the three accounts of this event in Acts mentions a horse. The horse found in later paintings is an artistic addition rather than a detail of Scripture.
Paul’s letters describe the event less as an abandonment of Israel than as a revelation of Jesus Christ and a divine call to proclaim him among the Gentiles. Paul believed that the God of Israel had revealed Israel’s Messiah and commissioned him for a new mission. After his encounter with Christ, Paul travelled into Arabia and returned to Damascus. Three years later, according to Galatians, he visited Jerusalem and spent fifteen days with Cephas, or Peter, while also meeting James, the brother of the Lord. Acts credits Barnabas with introducing him to an understandably cautious Christian community.
Opposition forced Paul to leave Damascus, reportedly escaping through an opening in the city wall in a basket. He spent time in his native region of Cilicia before Barnabas brought him to Antioch in Syria. Antioch became the principal base for the mission to Gentiles. The community there sent Barnabas and Paul to Cyprus and the cities of southern Asia Minor. Their preaching established Christian communities, but it also brought resistance, expulsion and violence. At Lystra, Paul was stoned and left for dead, yet he returned to encourage the new disciples.
The reception of Gentiles raised one of the earliest Church’s most difficult questions: whether Gentile converts needed to be circumcised and observe the full Mosaic Law. Acts narrates a formal assembly in Jerusalem, while Paul describes a Jerusalem meeting in Galatians. These accounts are commonly connected, although their exact chronological relationship remains debated. Paul received recognition for his mission to the Gentiles, while Peter’s mission was principally associated with the circumcised. Paul and Barnabas were also asked to remember the poor, a responsibility Paul pursued through a collection for the Church in Jerusalem.
Paul later confronted Peter at Antioch when Peter withdrew from table fellowship with Gentile Christians under pressure from others. Paul believed that this behaviour endangered the truth that Jewish and Gentile believers were united in Christ. The episode shows Paul’s uncompromising concern for the Gospel, but it also preserves real disagreement among apostolic leaders rather than presenting the early Church as free from tension.
Paul and Barnabas subsequently disagreed over whether St Mark should accompany another journey. They separated, with Barnabas taking Mark and Paul choosing Silas. Paul travelled through Syria and Cilicia, recruited St Timothy at Lystra and crossed into Macedonia following a vision in which a Macedonian pleaded for help. At Philippi, Lydia and her household received Baptism. Paul and Silas were beaten and imprisoned, but after an earthquake opened the prison, they remained rather than escaping and the jailer and his household were baptised.
Paul continued through Thessalonica and Beroea to Athens, where Acts portrays him addressing philosophers at the Areopagus. He acknowledged their religious searching and proclaimed the God who created all people and raised Jesus from the dead. Paul then travelled to Corinth, where he worked alongside St Priscilla and St Aquila because they shared his trade. He remained there for approximately eighteen months. His appearance before Gallio, proconsul of Achaia around AD 51–52, provides the strongest fixed point for reconstructing the chronology of his ministry.
A further period of mission centred upon Ephesus, an important city in the Roman province of Asia. Paul taught there for more than two years and faced opposition from craftspeople whose livelihoods depended upon the temple of Artemis. He continued visiting communities across Macedonia and Achaia while organising a collection for impoverished Christians in Jerusalem.
Paul’s mission was never a solitary achievement. His letters name a broad network of male and female collaborators, including Barnabas, Silas, Timothy, Titus, Priscilla, Aquila, Phoebe, Junia, Epaphroditus and many others. He could exercise forceful authority, but he also depended upon hospitality, financial assistance, messengers, local leaders and house churches. His communities were interconnected rather than being the work of an isolated religious genius.
Paul’s surviving letters address the practical and theological problems of particular communities. He wrote about the death and Resurrection of Christ, salvation by grace, faith working through love, Baptism, the Eucharist, the Church as Christ’s Body, the gifts of the Holy Spirit, the resurrection of the dead and the unity of Jews and Gentiles. His teaching on love in 1 Corinthians 13, on the Body of Christ in 1 Corinthians 12 and on Christian hope in Romans 8 continues to shape the Church’s prayer and doctrine.
Thirteen New Testament letters identify Paul as their author. The Church receives all thirteen as canonical Scripture and as part of the Pauline apostolic witness. Scholars generally recognise Romans, 1 and 2 Corinthians, Galatians, Philippians, 1 Thessalonians and Philemon as directly Pauline, while continuing to discuss the precise composition of the other six and the possible involvement of disciples, secretaries or later Pauline communities. Hebrews does not name Paul as its author and should not be counted among the thirteen letters bearing his name, even though it was traditionally associated with the Pauline collection.
Paul returned to Jerusalem despite warnings that imprisonment awaited him. After disturbances in the Temple, Roman soldiers took him into custody. Acts records a lengthy period of detention in Caesarea under the governors Felix and Festus. As a Roman citizen, Paul appealed to Caesar and was sent to Rome. The journey ended in a violent storm and shipwreck on Malta. Paul encouraged those aboard the ship, survived the disaster and ministered among the island’s inhabitants before continuing to Rome.
Acts ends with Paul living for two years under guarded conditions in Rome while openly preaching the Kingdom of God. It does not describe the outcome of his appeal or his death. Later accounts of a release, a mission to Spain and a second Roman imprisonment remain possible but cannot be reconstructed with certainty.
Ancient Christian testimony agrees that Paul eventually suffered martyrdom in Rome during Nero’s reign. First Clement, written from Rome near the end of the first century, remembers Paul’s endurance, preaching and martyrdom. Later testimony specifies that he was beheaded, a manner of execution traditionally connected with his Roman citizenship. The responsible date range is approximately AD 64–68 rather than the traditional date of 29 June AD 67 treated as documented fact.
Paul was buried according to ancient tradition beside the Ostian Way. A Christian monument associated with his burial was known there by the early centuries, and the Basilica of Saint Paul Outside the Walls was eventually built above the site. Examination of material from the ancient sarcophagus beneath the basilica found fragments dated to the first or second century, evidence consistent with the tradition but not independent proof of personal identity.
Paul’s holiness does not consist in an impressive personality overcoming every obstacle through willpower. He knew that his past could not be undone and called himself the least of the Apostles because he had persecuted the Church. His confidence rested instead upon grace: Christ had confronted him, forgiven him and entrusted him with a mission. Paul spent the remainder of his life allowing that grace to bear fruit through preaching, pastoral care, theological reflection, physical labour, suffering and service to communities across the Roman world.
