Calvin on Ephesians 5:21

God has so bound us to each other, that no man ought to avoid subjection. And where love reigns, there is a mutual servitude. I do not except even kings and governors, for they rule that they may serve. Therefore it is very right that he should exhort all to be subject to each other.

But as nothing is more contrary to the human spirit than to submit to others, he recalls us to the fear of Christ, who alone can tame our fierceness, that we may not refuse the yoke, and subdue our pride, that we may not be ashamed of serving our neighbors.
