This Roman-named believer from Thessalonica traveled with Paul's delegation carrying the collection for Jerusalem's poor. His name ('second' in Latin) was common in the empire, possibly indicating birth order. Luke's brief mention situates Secundus among a multi-ethnic team representing various churches: Sopater from Berea, Aristarchus and Secundus from Thessalonica, Gaius from Derbe, Timothy, and Tychicus and Trophimus from Asia. The list illustrates the geographical scope and unity of Paul's Gentile mission.
