The Greek word Asianos (Ἀσιανός) means "belonging to Asia" or "an Asian" — a resident or native of the Roman province of Asia (western Turkey). It appears only once in the New Testament, in Acts 20:4, where it identifies Tychicus and Trophimus as men from the province of Asia.
Acts 20:4 lists the delegation accompanying Paul to Jerusalem with the collection for the poor: "Sopater from Berea, Aristarchus and Secundus from Thessalonica, Gaius from Derbe, Timothy, and Tychicus and Trophimus from the province of Asia." This multi-ethnic, geographically diverse team represented the churches that had participated in the collection — a living demonstration of the unity of the body of Christ across racial and regional lines. The collection itself was a profound act of solidarity: Gentile churches of Asia, Macedonia, and Achaia contributing to the impoverished Jewish believers in Jerusalem.
