Paul arrived in Corinth during his second missionary journey after preaching in Athens. Acts 18 states that he met Aquila and Priscilla and worked with them because they shared the trade of tentmaking. Paul initially reasoned in the synagogue and later continued his ministry from the house of Titius Justus.
The Lord encouraged Paul in a vision to continue speaking, and Acts records that he remained in Corinth for a year and six months. Among those who believed was Crispus, the ruler of the synagogue.
Jewish opponents eventually brought Paul before Gallio, the proconsul of Achaia. Gallio refused to adjudicate what he regarded as an internal religious dispute. The Corinthian church subsequently became the recipient of important Pauline teaching concerning division, morality, marriage, spiritual gifts, love, resurrection, generosity, and Christian worship.
