John Wesley on Acts 10:1

And there was a certain man - The first fruits of the Gentiles, in Cesarea - Where Philip had been before, Acts 8:40; so that the doctrine of salvation by faith in Jesus was not unknown there. Cesarea was the seat of the civil government, as Jerusalem was of the ecclesiastical. It is observable, that the Gospel made its way first through the metropolitan cities. So it first seized Jerusalem and Cesarea: afterward Philippi, Athens, Corinth, Ephesus, Rome itself. A centurion, or captain, of that called the Italian band - That is, troop or company.
