The Greek noun anthupatos (ἀνθύπατος) refers to a Roman proconsul — a former consul appointed by the Roman Senate to govern a senatorial province. It appears four times in the New Testament, in Acts 13 (Sergius Paulus of Cyprus), Acts 18 (Gallio of Achaia), and Acts 19 (reference to "proconsuls").
The proconsuls in Acts represent the intersection of the gospel with Roman imperial power. Sergius Paulus (Acts 13:7–12) is remarkable: described as "an intelligent man," he summoned Barnabas and Paul, eager to hear the word of God. After Paul blinds the sorcerer Elymas, Paulus believed — one of the first senior Roman officials to respond to the gospel. Gallio (Acts 18:12–17) dismissed the Jewish charges against Paul as internal religious dispute, inadvertently protecting Paul's ministry by Roman law. The gospel did not operate in a religious vacuum — it engaged real political authorities, and God used both the open and closed doors of Roman governance to advance His kingdom.
