3 John

What 3 John is about

Third John is a personal letter to a man named Gaius, and it turns on a conflict inside one congregation.

Gaius has been putting up travelling missionaries — people who went out, as the elder puts it, for the sake of the Name and accepted nothing from unbelievers. The elder commends him warmly, says he has no greater joy than to hear that his children are walking in the truth, and asks him to keep sending them on their way in a manner worthy of God.

Then comes Diotrephes, who is one of the few named troublemakers in the New Testament. He likes to put himself first. He refuses to welcome the missionaries, talks maliciously about the elder, and — the sharpest detail — puts out of the church anyone who does welcome them. The elder says he will address it when he comes.

Finally Demetrius, who is well spoken of by everyone, is commended as the sort of person to imitate: whoever does good is from God; whoever does evil has not seen God.

Where it sits in the story

It is the shortest book in the Bible by word count in the original Greek, and it forms a pair with 2 John, which has one verse fewer. The two are instructive read together: 2 John tells a church not to host teachers who deny that Christ came in the flesh; 3 John rebukes a leader who refuses hospitality to faithful ones. The principle is not a general suspicion of outsiders but discernment about the message.

Why it is worth reading

Because it is a snapshot of ordinary church trouble — a domineering leader, a disputed guest list, people caught in between — recorded without embarrassment in scripture. And because it names hospitality as genuine ministry, not a supporting service to it.
