Who Was the Apostle Paul? His Life, Mission and Legacy

Few figures have shaped the Christian faith as profoundly as the Apostle Paul. A man of two worlds — a devout Jew steeped in the Law and a citizen of the Roman Empire — he carried the Gospel from the synagogues of the eastern Mediterranean to the very heart of Rome. His letters remain among the most read and most studied texts in the world, and his story of transformation continues to speak to believers of every tradition. This is an overview of his life, his mission and the legacy that endures.

A Son of Tarsus

Paul was born in Tarsus, the principal city of Cilicia in what is today southern Türkiye. He tells us so himself, describing his birthplace in his own words as "a citizen of no mean city" (Acts 21:39). Tarsus was no provincial backwater. It was a prosperous centre of trade and learning, sitting where inland routes met the sea, home to schools of philosophy and a mingling of Greek, Roman and Jewish cultures.

Into this cosmopolitan setting Paul was born a Jew of the tribe of Benjamin, and — remarkably — a Roman citizen by birth (Acts 22:28). Roman citizenship was a rare and valuable inheritance in the eastern provinces. It would later shape the course of his ministry, granting him legal protections and, ultimately, the right to appeal his case to Caesar in Rome.

To understand why this single city matters so much to the Christian story, it is worth reading more about where Tarsus is and why it holds such enduring significance.

A Pharisee Trained in the Law

Though born in Tarsus, Paul received a rigorous religious formation. In his defence before the crowd in Jerusalem he describes himself as "brought up in this city at the feet of Gamaliel, and taught according to the perfect manner of the law of the fathers" (Acts 22:3). Gamaliel was among the most respected teachers of the age, and to have studied under him marked Paul as a scholar of the first rank.

He was, by his own account, a Pharisee — zealous, learned and utterly devoted to the traditions of his people (Philippians 3:5–6). That zeal, however, first expressed itself in opposition to the followers of Jesus. Paul, then known by his Hebrew name Saul, became a determined persecutor of the early Church. He was present, consenting, at the stoning of the deacon Stephen (Acts 7:58–8:1), and he set out for Damascus armed with letters authorising him to arrest the disciples he found there.

The Road to Damascus

Everything changed on that road. As Saul neared Damascus, a light from heaven flashed around him, and he fell to the ground and heard a voice: "Saul, Saul, why persecutest thou me?" (Acts 9). Blinded, he was led into the city, where a disciple named Ananias, sent by the Lord, laid hands on him. His sight was restored, he was baptised, and the persecutor became a preacher.

Paul never tired of returning to this moment. In his letter to the Galatians he insists that the Gospel he preached came not from any human source but through a direct revelation of Jesus Christ (Galatians 1). The conversion near Damascus is not merely a dramatic episode; it is the foundation of his entire apostolic authority and the pattern of grace he would proclaim for the rest of his life — that God calls, transforms and commissions even those who once opposed him.

The Missionary Journeys

From Damascus and Antioch, Paul set out on the great journeys that would define his life. Over some fifteen years he travelled thousands of miles by land and sea, across Cyprus, Asia Minor, Macedonia and Greece, planting communities of believers in city after city — Antioch, Ephesus, Philippi, Thessalonica, Corinth and many more.

His method was consistent: he preached first in the synagogues, reasoned from the Scriptures, and then turned to the wider Gentile world. His labours were marked by hardship — shipwreck, imprisonment, beatings and constant danger — which he catalogues with unflinching honesty (2 Corinthians 11:24–28). Yet the churches he founded became the seedbed of Christianity across the Roman world. It was at Antioch, the city where the disciples were first called Christians, that his missionary vocation took shape, and those who wish to trace his routes can explore the missionary journeys of Saint Paul in fuller detail.

The Letters

Wherever Paul could not remain, he wrote. His epistles — to the Romans, the Corinthians, the Galatians, the Philippians and others — were letters of encouragement, correction and profound theological reflection, addressed to real communities facing real questions. In them he articulated the heart of the Christian message: justification by faith, the reconciling work of the Cross, life in the Spirit, and the unity of Jew and Gentile in one Body of Christ.

These letters are among the earliest Christian writings we possess, several of them composed before the Gospels reached their final written form. Read together, they offer not abstract philosophy but a pastor's heart poured out for the people in his care — a witness that opens up its richness anew for every generation of readers.

Martyrdom and Enduring Legacy

Paul's journeys eventually brought him, as a prisoner, to Rome. There, according to ancient and unbroken Christian tradition, he was martyred during the reign of Nero, put to the sword as a Roman citizen. He is honoured together with the Apostle Peter, who was martyred in the same city — the two great pillars of the Church in the imperial capital.

For this reason the Church keeps 29 June as the Solemnity of Saints Peter and Paul, one of the most venerable feasts in the Christian calendar, celebrated across the Catholic, Orthodox and many Protestant communions. You can read more about the Feast of Saint Paul and its meaning.

Why does Paul still matter? Because his life is the story of grace itself — a persecutor made an apostle, a proud scholar humbled and remade. His letters continue to form Christian faith and thought, his missionary zeal remains a model for evangelisation, and his witness unto death testifies to a conviction stronger than fear. Nearly two thousand years on, the tentmaker of Tarsus still teaches, still challenges and still consoles.

A Word About 2027

From 28 to 30 June 2027, the inaugural St Paul Global Week will gather pilgrims in Tarsus and Mersin, in the very region where Paul was born, to honour his life and mission around the Solemnity of Saints Peter and Paul. The Feast Day programme will be shared live with the wider world for all who cannot travel. For those who feel drawn to walk, even briefly, in the footsteps of the Apostle, a pilgrimage to Tarsus offers a quiet and moving encounter with the place where his story began.
