3 John 1:10
So when I come, I will call attention to what he is doing, spreading malicious nonsense about us. Not satisfied with that, he refuses to welcome the believers and hinders those who want to do so and puts them out of the church — Diotrephes' opposition manifests in multiple ways: slander against the elder, refusal of hospitality, suppression of hospitable impulses in others, and excommunication of those who resist his authority. The comprehensiveness of his opposition suggests a systematic campaign to consolidate power and eliminate rivals, making him a threat not merely to the elder's reputation but to the entire ecosystem of early Christian hospitality and itinerant ministry. His excommunication of faithful believers reveals a weaponization of church discipline for personal ends.
