Diotrephes

Diotrephes was a domineering church leader addressed in 3 John 9–10, condemned by the elder (John) for loving to be first among them, refusing to acknowledge the elder's authority, spreading malicious gossip against him, refusing to welcome itinerant missionaries, and expelling from the church those who did show hospitality to them. His behavior represents the kind of authoritarian personality that threatened the unity and hospitality of early house churches. He stands in sharp contrast to the commended Demetrius in the same letter.
