Diotrephes is causing problems
9 I have already written something to the group of believers there. But Diotrephes refuses to accept our authority. He really wants to be the only leader among them. 10 So, when I arrive there myself, I will speak to the believers about this. I will tell them clearly about the bad things that Diotrephes is doing. He tells other people bad things about us that are not true. Even that is not enough for him. He himself refuses to receive the believers who are visiting. Then he stops anyone else who wants to receive those visitors. If anyone tries to do that, Diotrephes sends them away from the group of believers.
1:10These visitors are Christians who are travelling to different places to teach the message about Jesus Christ. See 3 John 1:7.
