This article is the sixth in a seven-part series exploring the historical, literary, and theological reality of the Apostle Paul. Relying on modern historical-critical scholarship, this series unpacks who Paul was, what his core ideas were, and his true role in the early church. Part 6 explores the bitter, historical rivalry between Paul and the original disciples in Jerusalem, lifting the veil on a deeply divided early Christian movement.

When reading the New Testament, it is easy to imagine the early Christian church as a unified, harmonious community where all the apostles worked together in perfect agreement. The Book of Acts, written decades later, largely portrays the early movement this way—as a smooth, divinely orchestrated expansion from Jerusalem to Rome.

However, when historical-critical scholars read Paul’s own letters, a radically different picture emerges.

The historical reality is that the early Jesus movement was messy, fractured, and deeply divided. Paul was not universally loved by his fellow Christians. In fact, he engaged in a bitter, high-stakes theological war with the original disciples in Jerusalem—specifically Peter and James, the brother of Jesus. Their conflict centered on a question that threatened to tear the infant movement apart: Who gets to sit at the table?

The Myth of the Unified Church

To understand the conflict, one must understand the power dynamics of the early Jesus movement.

After the crucifixion, the center of the movement was firmly located in Jerusalem. The church there was led by the “Pillars”: Peter (whom Paul calls Cephas), John, and most importantly, James, the biological brother of Jesus. This Jerusalem community was strictly Jewish. They worshipped in the Temple, kept kosher dietary laws, and viewed their movement as a faithful sect within Judaism.

Paul, meanwhile, was out in the diaspora (places like modern-day Turkey and Greece), bringing non-Jews (Gentiles) into the movement. As established earlier in this series, Paul vehemently taught that Gentiles did not need to be circumcised or follow the Jewish Law to join.

When word reached Jerusalem that Paul was telling pagans they could be full members of God’s family without following the Torah, the conservative leaders in Jerusalem were alarmed. To them, Paul was preaching a dangerous, lawless compromise.

The Jerusalem Council

The tension came to a head around 49 CE, leading to a famous summit known as the Jerusalem Council. We have two accounts of this meeting: a highly sanitized version in the Book of Acts (Chapter 15), and Paul’s own raw, emotional account in his letter to the Galatians (Chapter 2).

According to Paul, he did not go to Jerusalem to get permission or to submit to Peter’s authority. He went because of a “revelation,” and he brought a Greek convert named Titus with him as a test case, deliberately refusing to circumcise him.

Paul met privately with the Pillars. According to his letter, they reached a fragile, grudging truce. James, Peter, and John agreed that Paul’s law-free gospel was valid for the Gentiles, while they would continue to preach a law-observant gospel to the Jews. They shook hands, dividing the ancient world into two distinct missionary spheres.

But this truce left a massive practical problem unresolved: What happens when Jewish believers and Gentile believers belong to the same local church?

The Explosion at Antioch

The fragile peace shattered shortly afterward in the city of Antioch (in modern-day Syria).

Antioch was a mixed community of Jewish and Gentile believers. In the ancient world, eating together (table fellowship) was a profound sign of unity. For the Christians, it was essential for sharing the Lord’s Supper. But the Jewish dietary laws (kashrut) strictly forbade Jews from sharing meals with Gentiles, whose food was considered ritually impure.

When Peter visited Antioch, he initially ate with the Gentile Christians, implicitly accepting Paul’s view that the old boundaries were gone. However, shortly after, a delegation of strict, conservative Jewish-Christians arrived from Jerusalem, sent by James.

Intimidated by James’s men, Peter panicked. He withdrew from the Gentiles and refused to eat with them anymore. The rest of the Jewish believers in Antioch, including Paul’s close companion Barnabas, followed Peter’s lead, segregating the church.

Paul exploded. In Galatians 2, he writes that he confronted Peter publicly, in front of the entire church, accusing the most famous disciple of Jesus of rank hypocrisy. “If you, though a Jew, live like a Gentile and not like a Jew, how can you compel the Gentiles to live like Jews?” Paul demanded.

Who Won the Argument?

In Sunday school lessons, it is usually assumed that Paul won this argument, Peter apologized, and everyone moved on. But historical-critical scholars point out a glaring omission in the text: Paul never tells the Galatians how the argument ended.

In ancient rhetoric, if you win a public debate, you boast about the victory. The fact that Paul leaves the story hanging strongly suggests to historians that Paul actually lost the confrontation at Antioch.

The historical evidence indicates that the church in Antioch likely sided with Peter and James. This devastating defeat may explain why Paul subsequently left the region of Syria, broke ties with Barnabas, and launched his independent missionary work further west into Greece and Asia Minor.

Ultimately, this bitter rivalry highlights how much the early church struggled to define itself. James and Peter represented a vision of a movement firmly anchored in Jewish law and tradition. Paul represented a radical, boundary-breaking universalism. While James’s faction dominated the earliest years in the East, the destruction of Jerusalem by the Romans in 70 CE eventually shattered their power base. It was Paul’s portable, Gentile-friendly theology that ultimately survived, forever shaping the trajectory of the Christian religion.

This concludes Part 6/7 of this series. In our final installment, Part 7 of “The Historical Paul: Life, Letters, and Legacy,” we will step inside the ancient Roman living room to explore the radical, controversial social dynamics of Paul’s earliest house churches.
