The Greek name Galliōn (G1058) refers to Lucius Junius Gallio, the Roman proconsul of Achaia (Greece) during Paul's time in Corinth (Acts 18:12-17). Born Marcus Annaeus Novatus, he was adopted by the rhetorician Junius Gallio and took his name. He was the brother of the philosopher Seneca.
Gallio's dismissal of the Jewish charges against Paul — "I refuse to be a judge of these things" (Acts 18:15) — was providentially significant for the early church. His ruling effectively declared Christianity a matter of Jewish internal dispute rather than a Roman legal offense, giving Paul and the church legal breathing room in the Roman Empire. Gallio's indifference to spiritual matters is a warning; his inadvertent service to the gospel is a reminder of God's sovereignty over pagan rulers.
