Acts 18 records that while Gallio was proconsul of Achaia,
Paul's opponents made a united attack and brought him before the judgment seat, accusing him of persuading people to worship God contrary to the law. Before Paul could answer, Gallio dismissed the case. He said that if the matter involved wrongdoing or serious crime he would hear it, but disputes about words, names, and Jewish law were for them to settle themselves. He drove them from the tribunal. The crowd then seized Sosthenes, ruler of the synagogue, and beat him before the judgment seat, while Gallio did not intervene. Gallio is historically significant because an inscription from Delphi helps date his proconsulship and therefore provides an important chronological anchor for Paul's Corinthian ministry.
