Therefore subject yourselves to every ordinance of man for the Lord's sake: whether to the king, as supreme;
Whether it be to the king - It has been commonly supposed that there is reference here to the Roman emperor, who might be called king, because in him the supreme power resided. The common title of the Roman sovereign was, as used by the Greek writers, ᾀυτοκράτωρ autokratōr, and among the Romans themselves, “imperator,” (emperor;) but the title king was also given to the sovereign. John 19:15, “we have no king but Cesar.” Acts 17:7, “and these all do contrary to the decrees of Cesar, saying that there is another king, one Jesus.” Peter undoubtedly had particular reference to the Roman emperors, but he uses a general term, which would be applicable to all in whom the supreme power resided, and the injunction here would require submission to such authority, by whatever name it might be called. The meaning is, that we are to be subject to that authority whether exercised by the sovereign in person, or by those who are appointed by him.
