Origin of the Church at Corinth

Paul established the church in Corinth during his second missionary journey some twenty years after the resurrection of Jesus Christ. The detailed account of its foundation is given in Acts 18:1-17. Before coming to Corinth Paul ministered in Macedonia and Athens, but he had very little success. He then came to Corinth and stayed there for 18 months or more. Paul stayed in Corinth more than any other cities, with single exception of Ephesus. We read that Paul stayed with Aquila and Priscilla (Acts 18:2, 3). They evidently were believers, and recently expelled from Rome by a decree of the emperor Claudius.
Paul began his ministry by preaching in the synagogue each Sabbath and working during the week at his trade of tent making Acts 18 1-4. During that time many of the Corinthians hearing the gospel believed, and were baptized. Some of the Carly believers in Corinth were Crispus, Sosthenes, Gaius, Erastus, Justus etc. This group formed the nucleus of the Corinthian church which grew rapidly Acts. 18:8, 10. There were Jewish converts but majority were Gentiles. Paul suffered constant opposition from Jewish authorities, but by the time he left he had firmly established the Corinthian church.
