The emperor who accidentally split the early church in two

Sometime around the year 120 A.D., roughly 70 years after the events we're about to discuss, a Roman historian sat down to write a biography of Emperor Claudius. His name was Gaius Suetonius Tranquillus. He had access to imperial archives. He was careful, he was detailed, and in one sentence, he accidentally recorded one of the most significant moments in early Christian history, without having any idea what he was describing. The line reads, in Latin, that Claudius expelled the Jews from Rome because they were causing constant disturbances at the instigation of one Crestus. Crestus. Not a name Suetonius recognized. Not a name that appears anywhere else in Roman historical records. Because it wasn't a Roman name at all, it was a mishearing. And what Suetonius was actually describing, without knowing it, was a church in crisis. Claudius became emperor in 41 A.D., under circumstances that were, to put it gently, undignified. After the assassination of the deeply unstable Caligula, the Praetorian Guard, the imperial bodyguards, found Claudius hiding behind a curtain in the palace. They declared him emperor on the spot. He was fifty years old. He had a stutter. He had been kept out of public life his entire adult life because his family considered him an embarrassment. He turned out to be a surprisingly competent administrator. He expanded the empire into Britain. He reformed the legal system. He completed major infrastructure projects. Historians generally assess him as one of the more effective emperors of the first century. But he was also deeply anxious about public order. Riots in Rome, especially in the densely populated Jewish quarter of Trastevere, were a real problem for him. And in 49 A.D., the Jewish community of Rome was generating a lot of noise. The reason, as Suetonius tells us, was crestus. To understand what was actually happening, you have to picture the Jewish community of Rome in the late 40s A.D. It was large. Estimates range from 20,000 to 50,000 people in a city of about a million. It was organized into multiple synagogues scattered across different neighborhoods. And inside those synagogues, a debate had been building for years. Some members of the Jewish community had come to believe that Jesus of Nazareth, a man executed by Roman authority in Judea roughly 15 years earlier, was the Messiah. The promised deliverer of Israel. Others found this claim deeply offensive or simply impossible. This debate was not quiet. It was loud. It spilled into the streets. It created divisions inside families, inside communities that had known each other for generations. And at some point, it became disruptive enough, disorderly enough, that it attracted the attention of the Roman authorities. For Claudius, this was not a theological problem. He had no interest in whether Jesus was the Messiah or not. He had an order problem. And his solution was Roman. Remove the people causing the disturbance. In 49 A.D., he issued an edict of expulsion. All Jews, regardless of whether they were followers of Jesus or not, were ordered to leave the city of Rome. Let's stay with Suetonius for a moment, because his one sentence is doing a lot of work. He writes, He expelled the Jews from Rome who were constantly making disturbances at the instigation of Crestus. Three things to notice. First, Crestus was a common enough Roman name. Suetonius could have been referring to a specific Jewish troublemaker named Crestus. Some historians argue for this reading. But, and this is significant, Crestus appears nowhere else in Roman records as a leader of the Roman Jewish community. For someone who apparently caused the expulsion of tens of thousands of people, he's remarkably invisible. Second, the Greek names Crestus and Christos were frequently confused by Roman writers. We have multiple examples of this exact substitution in ancient texts. The vowels e and i were nearly identical in pronunciation in first-century Greek-influenced Latin. Third, and most tellingly, Suetonius writes as if Crestus is present in Rome, leading the disturbances. But if this is Jesus of Nazareth, he had been dead for 15 years by 49 A.D. What Suetonius is almost certainly recording, without understanding it, is not a riot led by a man named Crestus. It's the explosive debate inside the Roman synagogues over whether a man named Crestus, Christ, was the promised Messiah. The fights were real. The disruption was real. The expulsion was real. Suetonius just didn't know what he was looking at. The expulsion of 49 A.D. removed everyone of Jewish origin from Rome. That included Jewish followers of Jesus, who had been part of the Roman Church since its very beginning. Among them, a tentmaker named Aquila, and his wife Priscilla. We know this because Acts 18 tells us directly. When Paul arrived in Corinth on his second missionary journey, he found them there, recently arrived from Italy because of Claudius' edict. He moved in with them. They made tents together. They became, over time, some of his closest colleagues. Their names appear in Romans 16.3, in Paul's greetings to the Roman Church, written years later, after they had returned. But here's what most teaching on Romans never addresses. What happened in Rome during the five years of the expulsion? The Jewish believers were gone. Every single one of them. The leaders, the founders, the people who remembered the beginning. The Gentile believers, who had always been a minority in the community, were left holding the thing together. Think about what five years does. Five years of meeting without Jewish calendar observance, because there was no one to observe it with. Five years of reading the apostles' letters without the interpretive framework of Torah study. Five years of developing their own understanding of what it meant to follow Jesus without the Jewish background that had shaped everything. Five years is long enough to feel like this is just how things are. And then, in 54 A.D., it ended. Claudius died. Nero took the throne. The expulsion lapsed. Jewish believers began returning to Rome, and they walked into a church that had reorganized itself around their absence. To be clear about something, the Gentile believers hadn't done anything wrong. They had followed what the apostles taught them. Paul himself, and Peter and James, had spent years arguing that Gentiles were fully included in God's covenant through faith in Jesus without needing to take on the full framework of Jewish practice. This was not a fringe position. It was the majority position of the apostolic leadership. The Gentile Roman Church had built their community on solid ground. But here's the problem. The returning Jewish believers came back to a community that no longer looked Jewish. The calendar was different. The practices were different. The leaders were different. The whole shape of the thing was different. And some of the returning believers, understandably, humanly, started to question whether what had been built in their absence was really legitimate, whether it had drifted from the covenant, whether their Gentile brothers and sisters were cutting corners. And some of the Gentile believers, equally understandably, started to wonder whether the returning Jewish believers were going to try to reimpose a framework that the apostles themselves had said wasn't required. Both sides thought they had Scripture on their side. Both sides were probably right about some things. Both sides were wrong about what to do with the tension. This is the community. This is who Paul is writing to. When you know all of this, you start to read Romans differently. The famous opening, I am not ashamed of the gospel, to the Jew first, and also to the Greek, is not just a theological statement. It's a direct address to both groups in the room. Neither one of you is first. Neither one of you has a higher claim. The long argument in chapters 1 through 3, where Paul systematically demonstrates that both Jews and Gentiles stand equally before God's judgment, that's not abstract theology. It's the framework the Roman Church desperately needed to stop looking down on each other. Chapters 9 through 11, the famously difficult section about Israel's election and the Gentiles. Those chapters aren't an abstract philosophical puzzle. They're Paul explaining to a Gentile majority church why their Jewish brothers and sisters still matter. Why the covenant with Israel isn't canceled. Why you cannot build your theology on the assumption that God has moved on from His people. Every major section of Romans lands differently when you know what room it was written into. Paul gives the letter to a woman named Phoebe, deacon of the church at Sentrier, the port of Corinth, who is traveling to Rome on her own business. She carries it across the Mediterranean. When she arrives, she doesn't just hand it over. In the ancient world, the person who carried a letter was also expected to read it aloud and explain it. Phoebe is not a postwoman. She is the first interpreter of Romans. Picture Phoebe standing before the Roman Church, both groups in the same room, the tension between them unresolved, and beginning to read. I, Paul, a servant of Jesus Christ, called to be an apostle. She knows the history we've just walked through. She knows who's in the room. Paul knew she would. He wrote the letter, knowing it would be read by people who had been on opposite sides of one of the most painful fractures in the early church. He wrote it anyway. He wrote it for them. He wrote it, as Tertius put it, in the one line we still have from his hand, in the Lord. Next time, we'll look at what Paul actually says in the first three chapters, and why the first thing he does, writing into this specific room, is accuse everyone, both sides. Equally. See you then.
