Theme: John writes this letter to commend Gaius for supporting traveling teachers and to rebuke Diotrephes for refusing to welcome them.
Introduction
Author
The author is John the apostle. In the first verses of both 2 John and 3 John the author identifies himself as “the elder.” Note other similarities: “love in the truth” (v. 1 of both letters), “walking in the truth” (v. 4 of both letters) and the similar conclusions. See Introductions to 1 John and the Gospel of John: Author.
Date
The letter was probably written about the same time as 1 and 2 John (ad 85–95). See Introduction to 1 John: Date.
Occasion and Purpose
See Introduction to 2 John: Occasion and Purpose. Itinerant teachers sent out by John were rejected in one of the churches in the province of Asia by a dictatorial leader, Diotrephes, who even excommunicated members who showed hospitality to John’s messengers. John wrote this letter to commend Gaius for supporting the teachers and, indirectly, to warn Diotrephes.
