3 John 1:2
"Beloved, I pray that all may go well with you and that you may be in good health, as it goes well with your soul."
The most personal greeting in the NT: the desire for physical prosperity and health linked to the well-being of the soul. Spiritual health is the standard for total health. John desires that Gaius’s outward condition correspond to his inward state.
3 John 1:9-11
"I wrote something to the church, but Diotrephes, who likes to put himself first, does not acknowledge us. So if I come, I will bring up what he is doing, talking wicked nonsense against us. And not content with that, he refuses to welcome the brothers, and also stops those who want to and puts them out of the church."
Diotrephes — the first documented case of ecclesiastical authoritarianism. Characteristics: (1) desires to be first (philoproteuon); (2) rejects apostolic authority; (3) speaks maliciously; (4) refuses to host the brothers; (5) expels those who do. The love of power is incompatible with love for the brothers.
