Therefore you must be subject, not only for wrath, but also for conscience's sake.
All Commentaries on Romans 13:5 Go To Romans 13
Augustine of Hippo
AD 430
This is helpful for understanding that because of this life we must be subject and not offer resistance if anyone wants to take something from us, if it is in his power to do so, because authority has been given to him over temporal things, which will pass away. We are not to be subject in those good things which remain forever but only in the needs of this age. But when he says “one must be subject,” lest anyone submit to the authorities halfheartedly and not from pure love, Paul adds: “not only to avoid … wrath but also for the sake of conscience.” That is to say, you should not submit simply to avoid the authority’s anger, which can be done by pretense, but so that you might be assured in your conscience that you are doing this out of love for him. For you submit at your Lord’s command.
