Besides the special necessity for Christians in such an attitude toward rulers, namely, not giving occasion for Christians to be slandered, the Apostle also indicates several general grounds for it. First is God’s good pleasure in this. Second is that higher spirit of life by which Christians must be guided. They are persons who have wholly withdrawn from evil and wholly surrendered themselves to God. They are servants who have dedicated themselves to entire service of Him, that is, to the fulfillment of His good will, or to the doing of good.
This good should be pleasing to all chiefs, rulers, and kings. By the determination of the same will of God, they are appointed to encourage those who do good and to punish wrongdoers. “Do you wish not to fear authority?” says the Apostle Paul. “Do what is good, and you will receive praise from it” (Rom 13:3).
The Apostle’s conclusion is remarkable: “Honor all men. Love the brotherhood. Fear God. Honor the king.” Here, in a few words, the mutual relations of Christians are defined. Their duties toward God, the king, and other people are set forth. The first duties are indicated, whose fulfillment can lead to universal peace and salvation: Christian love, the fear of God, respect for one’s neighbors and for the king.
Jesus Christ said, “Render therefore to Caesar the things that are Caesar’s” (Mt 22:21). The Apostle advises obedience to every authority, or, more precisely, to every institution. By this he shows that Christians must obey even those authorities not directly appointed by God. They must carry out all their commands, except those contrary to God; see Acts 4:19.
