Truth that walks
Truth is not treated as abstract possession; it becomes visible in Gaius's conduct, hospitality, discernment, and imitation of good.
Welcome and refusal
Gaius receives workers and helps them forward, while Diotrephes refuses them and punishes willing hosts.
Testimony
Reports about Gaius, public testimony before a church, the witness to Demetrius, and the Elder's own witness make accountable evidence central.
The Name and the truth
The workers serve the Name, and those who support them become fellow workers with the truth.
Authority tested by conduct
The Elder appeals, promises to confront deeds, and offers testimony; Diotrephes's practical power is judged by malicious and coercive actions.
Personal relationship
Beloved language, hoped-for presence, peace, friends, and greetings by name keep the conflict from becoming an abstract leadership case.
