Diotrephes is a figure mentioned in the New Testament, specifically in the Third Epistle of John. He is noted for his negative example within the early Christian community. The Apostle John writes to Gaius, a beloved friend, and contrasts the behavior of Diotrephes with that of others who are faithful to the truth.

In 3 John 1:9-10 , John states, "I wrote to the church, but Diotrephes, who loves to be first, will not accept our instruction. So if I come, I will call attention to what he is doing, spreading malicious nonsense about us. Not satisfied with that, he even refuses to welcome the brothers and stops those who want to do so and puts them out of the church."

Diotrephes is characterized by his desire for preeminence and his rejection of apostolic authority. His actions include spreading false accusations against the Apostle John and refusing to show hospitality to traveling missionaries, which was a significant breach of Christian duty at the time. Furthermore, he actively hinders others who wish to support these missionaries, even going so far as to excommunicate them from the church.

The behavior of Diotrephes serves as a warning against pride and the rejection of legitimate spiritual authority. His example is often cited in discussions about church leadership and the dangers of self-centered ambition within the Christian community.

Demetrius

Demetrius is another individual mentioned in the Third Epistle of John, serving as a positive contrast to Diotrephes. While little is known about Demetrius outside of this brief mention, his character is commended by the Apostle John.

In 3 John 1:12 , John writes, "Demetrius has received a good testimony from everyone—and from the truth itself. We also testify for him, and you know that our testimony is true."

Demetrius is praised for his adherence to the truth and his good reputation among the believers. The commendation from John suggests that Demetrius is a faithful and trustworthy member of the Christian community, likely involved in the work of the church and supportive of the apostolic mission.

The mention of Demetrius highlights the importance of living a life that aligns with the truth of the Gospel and maintaining a good testimony among fellow believers. His example serves as an encouragement to Christians to uphold integrity and faithfulness in their walk with Christ.

Together, the accounts of Diotrephes and Demetrius in the Third Epistle of John provide a study in contrasts, illustrating the impact of one's character and actions on the health and unity of the church.
