What does the Bible say about Diotrephes?

Diotrephes is a significant figure mentioned in 3 John, characterized as one who desires to have preeminence among the believers. The Apostle John writes about him to Gaius, noting that Diotrephes not only refuses to receive the apostolic authority of John and his companions but also actively prevents others from welcoming them, thus casting them out of the church. This behavior reflects a spirit of pride and an unwillingness to submit to the authority of God’s appointed messengers, contrasting sharply with the humble service expected of true followers of Christ. Believers are urged to steer clear of such evil practices and to instead follow what is good, exemplifying the humility and servitude that Christ modeled.
