What was Paul doing before his conversion?

He was actively persecuting the early Church, traveling toward Damascus specifically to find and arrest Christians there — the text introduces him "breathing out murderous threats against the Lord's disciples" before the journey that would change his life.

What happened on the road to Damascus?

"Suddenly a light from heaven flashed around him. He fell to the ground and heard a voice say to him, 'Saul, Saul, why do you persecute me?'" (Acts 9:3-4) — Jesus identifies himself directly, and Paul is left blinded, needing to be led by the hand into the city.

Was Paul always called Paul?

No — he is introduced in Scripture as Saul, his Hebrew name, and the name Paul (his Roman name) becomes the one used consistently once his ministry turns toward the wider Gentile, Greek-speaking world.

How much of the New Testament did Paul write?

Thirteen of the New Testament's twenty-seven books are traditionally attributed to Paul, in the form of letters written to specific churches and individuals — making him, by output, the most prolific single contributor to the entire New Testament.

Saint Paul the Apostle

A persecutor, not a convert waiting to happen

Before he was an apostle, Paul — introduced in Scripture by his Hebrew name, Saul — was one of early Christianity's most committed opponents. He is present at the stoning of Stephen, the Church's first martyr, approving of the killing, and Acts describes him afterward as a man "breathing out murderous threats against the Lord's disciples," actively seeking authorization to travel to Damascus and arrest Christians there. Nothing in his introduction reads as a man on the verge of a change of heart. He is, by every account, moving in the opposite direction, with real authority and real intent.

Struck down on the road

The turning point comes without warning, mid-journey: "As he neared Damascus on his journey, suddenly a light from heaven flashed around him. He fell to the ground and heard a voice say to him, 'Saul, Saul, why do you persecute me?' 'Who are you, Lord?' Saul asked. 'I am Jesus, whom you are persecuting,' he replied" (Acts 9:3-5, NIV). The man he has been hunting identifies himself directly, by name, from a light Paul cannot see past. He is then told simply to "get up and go into the city, and you will be told what you must do" (Acts 9:6, NIV) — left blinded, and entirely dependent on the very community he had set out to destroy.

From Saul to Paul

The name change that follows the conversion — from Saul, his Hebrew name, to Paul, his Roman one — tracks the direction his ministry would take: away from a mission focused on the Jewish community he'd once policed on behalf of the religious authorities, and toward the wider Greek-speaking, Gentile world that would become the primary audience of his life's work. He would go on to make multiple extended missionary journeys across the Roman world, planting and corresponding with churches from Asia Minor to Greece to Rome itself.

The most prolific writer in the New Testament

Thirteen of the New Testament's twenty-seven books are traditionally attributed to Paul — letters written to specific churches and individuals, addressing real disputes, real theology, and real relationships rather than composed as abstract treatises. No other figure in the New Testament comes close to that volume of surviving material. It's a strange, almost uncomfortable fact of Christian history that so much of its foundational writing comes from a man who spent his early adulthood trying to destroy the very movement he would later spend the rest of his life building — and Paul himself never asked anyone to forget that part of the story.
