Acts 18
Acts 18 — Commentary and Meaning
The short answer
Acts 18 opens with Paul arriving in Corinth, a busy port city, where he meets a Jewish couple named Aquila and Priscilla. They have recently fled Rome because the emperor Claudius expelled the Jews from the city. Paul moves in with them and works alongside them, since all three are tentmakers by trade. The chapter shows the mission moving forward not through spectacle but through shared work, shared housing, and steady teaching — Paul reasons in the synagogue every Sabbath and eventually stays in Corinth a year and six months.
Then comes the courtroom scene. Paul's opponents drag him before Gallio, the Roman proconsul of Achaea, at the judgment seat. Gallio refuses to hear the case, dismissing it as a dispute about Jewish law rather than a crime — he declares he doesn't want to be "a judge of these matters." It reads like a minor episode, but it turns out to be one of the most historically important moments in the New Testament. An inscription discovered at Delphi names Gallio as proconsul in 51–52 CE, which means this scene can be pinned to a real date on a real calendar — and from that fixed point, the rest of Paul's ministry can be dated too.
The chapter's final movement belongs to Priscilla and Aquila. They travel with Paul to Ephesus and stay there when he moves on. When an eloquent teacher named Apollos arrives, knowing the story of Jesus only in part, the couple take him aside and explain the way of God more accurately. Notably, Priscilla is often named before her husband — unusual for the time, and a quiet signal of her prominence. Acts 18 thus holds two things together: history solid enough to date, and ministry ordinary enough to imitate.
What scholars say
N. T. Wright explains why the brief mention of Gallio in Acts 18:12 matters so much: a Delphi inscription placing him as proconsul of Achaea in 51–52 CE gave scholars a long-sought fixed point for dating Paul's life. Jaime Clark-Soles then turns to Prisca and Aquila — expelled from Rome, tentmaking alongside Paul, and later instructing Apollos — noting that Prisca's being named first may signal her prominence.
“That is the sense that historians have had when Gallio appears on the scene in Acts 18.12. Figuring out how to date Paul’s life and journeys has been a notorious puzzle for many generations of scholars. There were no fixed points, no landmarks, nothing really you could latch on to and say, ‘Here at least we are on solid ground.’ Then the archaeologists turned up an inscription in Delphi, a few miles north-west of Corinth, and quite suddenly we knew exactly where we were. Gallio, who was the younger brother of the famous philosopher Seneca (who was himself tutor to the Emperor Nero) was proconsul of Achaea in the second half of 51 and on into early 52, before leaving through ill health.”
“It’s noteworthy that Prisca is named first in Romans, since normally primacy went to the male. It may mean she is of a higher social status or is a more prominent leader. Acts 18:2–3 indicates she and Aquila left Rome under the edict of Claudius that expelled all Jews from Rome and went to Corinth, where, along with Paul, they plied their tent-making trade and spread the gospel. They then accompanied Paul first to Syria, then to Ephesus, where they remained while he traveled on (Acts 18:18–19). While they were in Ephesus, an Alexandrian Jew named Apollos arrived and began teaching Christian faith in the synagogue. Prisca and her husband (again, she is mentioned first) took him aside and schooled him more fully in Christianity.”
What it means for you
Acts 18 is encouraging precisely because so much of it is unglamorous. Paul makes tents. A displaced couple opens their home and their workshop. A gifted speaker accepts correction from two ordinary believers. If you have ever felt your work, your hospitality, or your quiet conversations don't count as real ministry, this chapter says otherwise.
It also offers reassurance of a different kind: the faith described here is anchored in actual history. The same chapter that models everyday discipleship also contains a scene that archaeology can date. Believing and doing, trusting and working — Acts 18 keeps them side by side.
Acts 18 in context
Acts 18 sits in the middle of Paul's second missionary journey. He has just left Athens, where his speech at the Areopagus met a mixed response, and he arrives in Corinth apparently alone until Silas and Timothy rejoin him. After the long Corinthian stay and the hearing before Gallio, Paul sails for Syria, stopping at Ephesus, where Priscilla and Aquila remain. The chapter closes by introducing Apollos, setting up Paul's own extended ministry in Ephesus in Acts 19.
