What this book is about

3 John is the shortest book in the Bible by word count, and it is full of people. The elder writes to his friend Gaius, and he opens with warmth: “I have no greater joy than this: to hear about my children walking in truth.” Traveling brothers, strangers to Gaius, have told the church of his love, and the elder praises him for welcoming them and sending them on their way.

Then a name comes up that the elder does not like. Diotrephes, “who loves to be first among them”, will not accept what the elder says. He does not welcome the brothers himself, and he forbids those who would, even putting them out of the assembly. The elder says he will speak of it when he comes.

His advice to Gaius is short: “don’t imitate that which is evil, but that which is good.” He speaks well of Demetrius, who is probably the one carrying the letter, and he hopes to see Gaius soon.

Background

Like 2 John, the letter is from the elder, traditionally the apostle John. It gives a rare glimpse of everyday tensions in an early church: who has authority, and who is to be received, and who gets the last word in a local church.

How Christians read it

Read beside 2 John, the letter shows the other side of hospitality: there, a warning against supporting false teaching; here, a call to support those who teach faithfully. It is often read as a study in contrasting kinds of leadership, one that serves and welcomes, and one that holds on to first place. Together the two letters show how much early churches depended on who was received and who was turned away.
