Receiving brothers

Within two verses, John accuses Diotrephes of refusing to “receive us” and refusing to “receive the brethren” (3 John 9-10). The first refers to an acknowledgement of authority; receiving “us,” the elder and his co-workers, would mean listening and obeying. The second refers to hospitality; receiving the brothers means welcoming and providing for them.

Is John perhaps hinting at some inherent connection between submission to authority and hospitality? Do these two forms of receiving something from outside somehow require each other?
