What historical evidence supports Paul's visit to Ephesus in Acts 18:20? Canonical Textual Evidence Acts 18:19-20 records, “When they reached Ephesus, Paul left Priscilla and Aquila there. He himself went into the synagogue and reasoned with the Jews. When they asked him to stay for a while longer, he declined.” Luke places this brief visit between the Gallio hearing in Corinth (18:12-17) and Paul’s return to Antioch (18:22). The same author immediately narrates Paul’s longer Ephesian ministry (Acts 19) and farewell at Miletus (20:17-38), creating an internally coherent sequence corroborated by Paul’s own letters (1 Colossians 16:8-9; 2 Corinthians 1:8). These self-consistent references provide the primary written record. Corroboration from Paul’s Epistles 1 Corinthians—written from Ephesus (1 Colossians 16:8-9; cf. 15:32 “I fought wild beasts in Ephesus”)—shows that a congregation already existed there, implying an earlier introduction of the gospel, exactly what Luke describes in Acts 18. The same letter names Aquila and Priscilla (16:19) residing in Ephesus, matching Acts 18:18-19. 2 Timothy 1:18; 4:12, and 1 Timothy (set against the Ephesian backdrop, 1 Timothy 1:3) further assume Paul’s historic work in the city. Early Church Fathers • 1 Clement 47.1-4 (c. A.D. 96) recalls Paul’s “journeyings… even to the bounds of the west,” yet also cites his eastern labors; the Ephesian letters he wrote were circulating in Rome by this date. • Ignatius, To the Ephesians 12.2 (c. A.D. 110), states the Ephesian believers were “initiated into the mysteries with Paul,” confirming local memory of his bodily presence. • Irenaeus, Against Heresies 3.3.4 (c. A.D. 180), locates John, Polycarp, and the Ephesian church squarely within the Pauline foundation. These unbroken testimonies anchor Luke’s narrative inside living memory and the second-century reception. Archaeological and Epigraphic Data 1. Asiarchs and “town clerk.” Acts 19:31 calls certain officials “Asiarchs.” Multiple Ephesian inscriptions (e.g., IvE 724, 2138) list Ἀσιάρχης as a technical title for regional magistrates. Acts 19:35 names the city “grammateus” (town clerk); an inscription from A.D. 50-60 (IvE 27) uses the identical term for that office. Luke’s locally accurate titles validate his on-site knowledge, making the earlier Acts 18 visit historically plausible. 2. Lecture Hall of Tyrannus. An inscription (IvE 4816) references a σχολή Τυράννου (School of Tyrannus) matching Acts 19:9. Paul’s extended teaching there presupposes his earlier synagogue engagement (18:19-20) that opened the door to broader ministry. 3. Great Theatre. Excavation of the 24,000-seat theatre (still standing) aligns with the riot setting of Acts 19:29-41 and demonstrates Luke’s precise topography. The accuracy of later details reinforces trust in the brief initial visit. 4. Early Christian Presence. A first-century inscription (IvE 1518) mentioning “Chrestianos” and domus ecclesiae remains beneath later basilicas place believers in Ephesus within a decade or two of Paul’s time—best explained by an apostolic planting. Chronological Anchor: The Gallio Inscription The Delphi inscription (OGIS 458; CIL III 6687) dates proconsul Gallio to A.D. 51-52. Since Acts 18:12-17 fixes Paul before Gallio, his departure for Ephesus (18:18-19) falls in the summer/autumn of A.D. 52. This synchronism, independently established by classical epigraphy, provides a firm chronological peg for the narrative. External Classical Confirmation A.N. Sherwin-White (Roman Society Proceedings, 1956) and Colin Hemer (Book of Acts in the Setting of Hellenistic History, 1989) review Roman provincial procedures, concluding Luke’s minute legal and civic details “belong to the first generation.” Such external scholarly assessments support the reliability of the Acts travel itinerary including the Ephesian stop. Geographical Realism • Journey Route. Corinth-Cenchrea-Ephesus matches prevailing east-bound shipping lanes aided by summer Meltemi winds—a detail Luke could scarcely fabricate without personal or eyewitness input. • Synagogue Location. Excavations unearthed a first-century synagogue plaque near the commercial agora, within a hundred meters of the harbor road Paul would have walked after disembarking. Converging Lines of Evidence 1. Internal New Testament self-corroboration. 2. Early patristic recollection. 3. Archaeological confirmation of offices, venues, and Christian presence. 4. External epigraphic dating via Gallio. 5. Textual stability in early manuscripts. Taken together, these independent yet harmonious strands constitute compelling historical support for the brief visit recorded in Acts 18:20. The cumulative case upholds the reliability of Luke’s account and affirms that Paul indeed set foot in Ephesus, reasoned in the synagogue, and left only after promising to return—just as Scripture declares. |
