John writes his third epistle to a faithful kingdom saint named Gaius.  In this letter, he mentioned two other men (Diotrephes and Demetrius), one evil and the other good (1 Jn 3:10).  Evidently, they were both leaders in the same church.  John had written a letter to their church and sent it with certain brethren.  They were rejected by Diotrephes, but received by Gaius and Demetrius.
