Who Was the Apostle Paul?

Understanding 1 Corinthians 15:9-10, Acts 9:1-19, Galatians 1:11-24, Philippians 3:4-11

Paul is arguably the most influential figure in Christian history after Jesus Himself. A Jewish Pharisee who hunted down Christians with official authorization, he was transformed by an encounter with the risen Christ into a tireless missionary, a profound theologian, and the author of nearly half the New Testament. His letters shaped Christian doctrine on justification, grace, the church, ethics, and the return of Christ — and continue to generate more theological scholarship than any other biblical writings.

Background: Saul of Tarsus

Paul was born as Saul in Tarsus, a major city in Cilicia (modern southeastern Turkey). He held Roman citizenship — a significant legal privilege — and was raised in a devout Jewish family of the tribe of Benjamin (Philippians 3:5). He was educated in Jerusalem under Gamaliel, one of the most respected rabbis of the era (Acts 22:3), and became a Pharisee — the strictest sect of Judaism.

Paul later described his pre-conversion credentials: 'Circumcised on the eighth day, of the people of Israel, of the tribe of Benjamin, a Hebrew of Hebrews; in regard to the law, a Pharisee; as for zeal, persecuting the church; as for righteousness based on the law, faultless' (Philippians 3:5-6). By every measure of Jewish piety, Saul was exceptional.

His zeal took a violent turn when the early Christian movement emerged. Saul was present at the stoning of Stephen, the first Christian martyr, 'giving approval to his death' (Acts 8:1). He then launched a systematic campaign: 'Saul began to destroy the church. Going from house to house, he dragged off both men and women and put them in prison' (Acts 8:3). He obtained letters from the high priest authorizing him to arrest Christians as far away as Damascus (Acts 9:1-2).

The Damascus Road (Acts 9)

On the road to Damascus, everything changed. '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).

This encounter was not a vision or a subjective experience in Paul's telling — it was an objective appearance of the risen Christ. Paul later listed it alongside the resurrection appearances to Peter, James, and the other apostles: 'Last of all he appeared to me also, as to one abnormally born' (1 Corinthians 15:8). The phrase 'abnormally born' acknowledges the unusual timing — Paul met the risen Christ after the ascension, outside the normal window of resurrection appearances.

Saul was blinded for three days and taken into Damascus, where a believer named Ananias — understandably terrified of the famous persecutor — was sent by God to restore his sight and baptize him (Acts 9:10-18). Immediately, Saul 'began to preach in the synagogues that Jesus is the Son of God' (Acts 9:20). The persecutor became the preacher.

Missionary journeys

After a period of preparation (including time in Arabia, Galatians 1:17), Paul launched three major missionary journeys that carried the gospel across the Roman Empire:

First journey (Acts 13-14): With Barnabas, Paul traveled through Cyprus and southern Asia Minor (modern Turkey), establishing churches in Pisidian Antioch, Iconium, Lystra, and Derbe. At Lystra, he was stoned and left for dead but recovered and continued (Acts 14:19-20).

Second journey (Acts 15:36-18:22): Paul traveled through Asia Minor and into Europe for the first time, establishing churches in Philippi, Thessalonica, Berea, Corinth, and Athens. In Athens, he delivered his famous Areopagus speech, engaging Greek philosophy with the gospel (Acts 17:22-31). In Corinth, he spent eighteen months and wrote 1 and 2 Thessalonians — his earliest surviving letters.

Third journey (Acts 18:23-21:17): Centered on Ephesus, where Paul spent over two years. His ministry was so effective that 'all the Jews and Greeks who lived in the province of Asia heard the word of the Lord' (Acts 19:10). During this period he wrote 1 Corinthians, 2 Corinthians, Galatians, and Romans — four of his most theologically significant letters.

Paul's theology

Paul's letters contain the most systematic theological reflection in the New Testament. His central themes include:

Justification by faith: Paul's most revolutionary contribution to theology. Against those who taught that Gentiles must keep the Jewish law to be saved, Paul argued that 'a person is not justified by the works of the law, but by faith in Jesus Christ' (Galatians 2:16). Righteousness is a gift received through faith, not a status earned through obedience. This does not mean works are irrelevant — genuine faith produces a transformed life — but the basis of acceptance before God is grace, not performance.

Grace: 'For it is by grace you have been saved, through faith — and this is not from yourselves, it is the gift of God — not by works, so that no one can boast' (Ephesians 2:8-9). Paul's understanding of grace was not abstract — it was rooted in his own biography. The man who deserved condemnation for persecuting the church received commission to build it.

The body of Christ: Paul developed the metaphor of the church as Christ's body — diverse members with different gifts, united by one Spirit, interdependent and essential (1 Corinthians 12). This vision of the church was radical in its inclusion: 'There is neither Jew nor Gentile, neither slave nor free, nor is there male and female, for you are all one in Christ Jesus' (Galatians 3:28).

The resurrection: Paul's fullest treatment appears in 1 Corinthians 15. The resurrection of Christ is the foundation of everything: 'If Christ has not been raised, your faith is futile; you are still in your sins' (15:17). But Christ has been raised, and His resurrection guarantees the future resurrection of all believers.

Ethics: Paul's ethical teaching flows from theology, not moralism. Because believers are united with Christ (Romans 6), they should live accordingly. His letters are typically structured with doctrinal sections followed by practical application — what God has done, therefore how we should live.

Suffering and imprisonment

Paul's ministry was marked by extraordinary suffering. He catalogued his hardships: 'Five times I received from the Jews the forty lashes minus one. Three times I was beaten with rods, once I was pelted with stones, three times I was shipwrecked, I spent a night and a day in the open sea. I have been constantly on the move. I have been in danger from rivers, in danger from bandits, in danger from my fellow Jews, in danger from Gentiles; in danger in the city, in danger in the country, in danger at sea; and in danger from false believers' (2 Corinthians 11:24-26).

He was imprisoned multiple times. His 'prison epistles' — Ephesians, Philippians, Colossians, and Philemon — were written from captivity, likely in Rome. Even in chains, he wrote: 'I have learned to be content whatever the circumstances' (Philippians 4:11) and 'For to me, to live is Christ and to die is gain' (Philippians 1:21).

Legacy and death

Tradition holds that Paul was executed in Rome under Emperor Nero, likely around AD 64-67, beheaded as a Roman citizen (crucifixion was reserved for non-citizens). His death is not recorded in Acts, which ends with Paul under house arrest in Rome, 'proclaiming the kingdom of God and teaching about the Lord Jesus Christ — with all boldness and without hindrance' (Acts 28:31).

Paul's thirteen letters (Romans through Philemon) constitute the largest single-author contribution to the New Testament. They were circulated among churches during his lifetime and recognized as Scripture within a generation of his death. Peter himself acknowledged their authority — and their difficulty: 'His letters contain some things that are hard to understand' (2 Peter 3:16).

Why Paul matters

Paul matters because he demonstrated that the gospel transforms the most unlikely people. The church's greatest enemy became its greatest advocate. His theology of grace — that God accepts sinners not because of their performance but because of Christ's finished work — remains the beating heart of Christian faith. And his life of relentless mission, endured suffering, and intellectual courage established the pattern for every generation of Christians who have carried the gospel across cultural boundaries since.
