Diotrephes was a man mentioned in the Third Epistle of John (verses 9–11). His name means "nourished by Jupiter". As Raymond E. Brown comments, "Diotrephes is not a particularly common name." In addition to being ambitious, proud, disrespectful of apostolic authority, rebellious, and inhospitable, the author of the letter says that Diotrephes tried to hinder those desiring to show hospitality to the brothers and to expel these from the congregation. Not even the location of Diotrephes' church can be determined from the letter. It is debatable whether the antipathy expressed in 3 John is based on "a theological dispute, a clash of competing ecclesiastical authorities, a disagreement about financial responsibilities for the mission, or personal dislike".
