Study Notes for Acts 18
Verse 1
Corinth was a major, wealthy, and morally lax Roman port city, making it a strategic center for Paul’s mission in Achaia (Southern Greece).
Verse 2
The expulsion of Jews from Rome by Emperor Claudius (c. AD 49) is a key historical marker, confirming the date of Paul's arrival (c. AD 50). This providential event connected Paul with Aquila and Priscilla, who became indispensable ministry partners.
Verse 3
Paul supported himself through manual labor (tentmaking), demonstrating the dignity of work and ensuring he could preach the gospel without being financially dependent on the new converts (cf. 1 Cor. 9:18).
Verse 5
The arrival of Silas and Timothy, likely bringing financial support from Macedonia, allowed Paul to stop working and devote himself entirely ('pressed in the spirit') to testifying that Jesus was the Messiah.
Verse 6
Shaking his garments symbolized severing responsibility for their rejection. This act formally marked a strategic turning point, shifting Paul’s primary mission focus in Corinth from the synagogue to the Gentiles.
Verse 7
The new meeting place was symbolically located right next door to the synagogue, positioning the burgeoning Christian church as a direct alternative to the Jewish center.
Verse 8
The conversion of Crispus, the chief ruler of the synagogue, was a significant blow to the Jewish establishment and a major victory for the Christian community.
Verse 9
This vision provided necessary divine encouragement when Paul was facing intense opposition, assuring him of protection and the effectiveness of his ministry.
Verse 10
God promises both security ('no man shall set on thee to hurt thee') and success ('I have much people in this city'), confirming that Paul's work in Corinth was divinely mandated.
Verse 11
Paul’s 18-month stay (c. AD 50-52) was foundational, during which he established the large and complex Corinthian church and likely wrote 1 and 2 Thessalonians.
Verse 12
Gallio was the Roman proconsul of Achaia. His time in office (c. AD 51-52) provides the most precise external date for Paul’s missionary career.
Verse 13
The charge was that Paul was persuading men to worship illegally, suggesting Christianity was not yet recognized under Roman law as a legitimate sect of Judaism (religio licita).
Verse 15
Gallio dismissed the case, viewing it as an internal Jewish dispute over 'words and names.' This decision established a crucial precedent, granting Christianity temporary legal immunity from Roman interference.
Verse 17
Sosthenes, likely the new synagogue ruler, was beaten, perhaps by Greeks who were anti-Jewish, or by Jews frustrated by the legal defeat. Gallio’s indifference (cared for none of those things) highlights the Roman lack of concern for religious squabbles.
Verse 18
Paul’s shorn head suggests he had completed a temporary Nazarite vow (Num. 6:1-21). This demonstrates his continued respect for Jewish piety and his desire to relate to Jewish believers.
Verse 19
Paul briefly ministered in Ephesus, a key city in Asia Minor, leaving Priscilla and Aquila there to establish the foundation for the future church.
Verse 21
Paul’s desire to keep the feast (likely Pentecost or Passover) reflects his continued commitment to maintaining ties with the mother church in Jerusalem. The phrase 'if God will' (Deo volente) shows submission to divine providence.
Verse 22
Landing at Caesarea, Paul went up to Jerusalem ('saluted the church') to report on the success of the mission, formally concluding his Second Missionary Journey, before returning to his home base in Antioch.
Verse 23
Paul immediately begins his Third Missionary Journey (c. AD 53-57), focusing first on revisiting and strengthening the churches he had previously founded in Galatia and Phrygia.
Verse 24
Apollos, an Alexandrian Jew, was highly educated, reflecting the intellectual center of Alexandria. His eloquence and mastery of the Hebrew Scriptures made him a formidable evangelist.
Verse 25
Apollos 'knew only the baptism of John,' meaning he understood repentance and the need for the Messiah, but lacked full knowledge of Jesus’ resurrection, ascension, and the indwelling of the Holy Spirit.
Verse 26
Priscilla and Aquila demonstrated humility and theological maturity by privately instructing the gifted Apollos. This highlights the vital teaching role of lay leaders in the early church.
Verse 27
The brethren provided Apollos with letters of recommendation, allowing him to move into Achaia (Corinth) where he would later play a significant role (cf. 1 Cor. 3:6).
Verse 28
Apollos’s strength lay in his powerful use of the Old Testament Scriptures to publicly refute Jewish opposition and demonstrate conclusively that Jesus was the promised Christ.
