John Wesley on Romans 13:1

St. Paul, writing to the Romans, whose city was the seat of the empire, speaks largely of obedience to magistrates: and this was also, in effect, a public apology for the Christian religion. Let every soul be subject to the supreme powers - An admonition peculiarly needful for the Jews. Power, in the singular number, is the supreme authority; powers are they who are invested with it. That is more readily acknowledged to be from God than these. The apostle affirms it of both. They are all from God, who constituted all in general, and permits each in particular by his providence. The powers that be are appointed by God - It might be rendered, are subordinate to, or, orderly disposed under, God; implying, that they are God's deputies or vicegerents and consequently, their authority being, in effect, his, demands our conscientious obedience.
