The conflict shows up in words and actions. Diotrephes spreads hostile accusations (“unjustly accusing us with wicked words”), refuses to welcome “the brothers,” blocks others who want to welcome them, and removes those people from the assembly (explicit claims). The writer plans to address these deeds publicly if he comes (explicit claim).

Where interpretation differs

Two details are not fully spelled out.

First, “the brothers” could mean a specific set of traveling messengers/workers connected to the writer, or more generally visiting believers who should be received. The immediate letter context leans toward traveling workers, but the phrase itself is broad.

Second, “throws out of the assembly” could mean a formal act of exclusion from the group’s meetings, or it could describe a more informal but still real social removal (for example, being barred from the host home where the group meets). Either way, the text portrays Diotrephes as using his influence to exclude people.

Why the disagreement exists

The letter gives only partial information about the earlier letter’s contents, who exactly “we” includes, and the exact social mechanics of being “thrown out.” Those gaps leave room for different reconstructions, even though the author’s evaluation of Diotrephes is clear.

What this passage clearly contributes

It presents a concrete picture of how power and reputation can disrupt shared Christian work: refusing communication, attacking others with accusations, and controlling hospitality and membership boundaries. It also shows that, at least in this setting, refusing to “receive” fellow workers is not treated as a small preference but as serious wrongdoing tied to a desire to be “first.” The writer claims the right to bring public accountability to these actions when present.
