The Third Letter of John - Introduction
This genuine letter is addressed to an individual member of a Christian church whose leader, Diotrephes, has refused to receive the emissaries of the Elder led by Demetrius. Gaius, the addressee, a man of probity, is asked to provide hospitality for Demetrius and his companions. The author is the same Elder who wrote 2 John, as the vocabulary and style indicate; also, the two letters are of equal length.
