3 John 1:9

“I wrote unto the church, etc] Where Gaius was a member: those who take Gaius to be the same with Paul's host, and whom he baptized at Corinth, think the church at Corinth is here meant; but it seems rather to be meant of some church in Asia nearer Ephesus; nor is it likely that John's first epistle should be here intended, which makes no mention of relieving the brethren, the ministers of the Gospel, that came from Judea: and that this epistle should not be preserved, need not seem strange; for it cannot be thought that everything that was written by him to particular persons, or churches, should be continued. The Alexandrian copy and one of Stephens's read, “I wrote something to the…”

“I wrote--The oldest manuscripts add "something": a communication, probably, on the subject of receiving the brethren with brotherly love (Jo3 1:8, Jo3 1:10). That Epistle was not designed by the Spirit for the universal Church, or else it would have been preserved. unto the church--of which Gaius is a member. loveth . . . pre-eminence--through ambition. Evidently occupying a high place in the Church where Gaius was (Jo3 1:10). among them--over the members of the Church. receiveth us not--virtually, namely, by not receiving with love the brethren whom we recommended to be received (Jo3 1:8, Jo3 1:10; compare Mat 10:40).”

“I wrote unto the church - That is on the former occasion when they went forth. At that time, John naturally commended them to the kind attentions of the church, not doubting but that aid would be rendered them in prosecuting their benevolent work among the Gentiles. The Epistle which was written on that occasion is now lost, and its contents cannot now be ascertained. It was, probably, however, a letter of mere commendation, perhaps stating the object which these brethren had in view, and soliciting the aid of the church. The Latin Vulgate renders this: “scripsissem forsan ecclesiae, “I would have written, perhaps, to the church, but Diotrephes,” etc. Macknight also renders this, “I would…”

“I wrote to the church - Probably that to which they came. But Diotrephes - Perhaps the pastor of it. Who loveth to have the preeminence among them - To govern all things according to his own will. Receiveth us not - Neither them nor me. So did the mystery of iniquity already work! 3 John 1:10”

“1:9-12 In these verses, John condemns Diotrephes and presents Demetrius as the model of a faithful Christian who lives according to the truth. Gaius is urged to emulate Demetrius. 1:9 I wrote to the church about this: This could refer to 1 John or to a letter that is now lost. • Diotrephes was full of pride and self-importance (cp. 1 Tim 3:6), motivated by selfish ambition. • refuses to have anything to do with us: This dissidence was one of the key issues John dealt with in 1 John (see, e.g., 1 Jn 2:19; 4:5-6). Diotrephes rejected the teachers sent by John and excommunicated any members of the church who did accept them. He wanted to rule the local church without answering to any outside…”

“who loveth: Ο φιλοπρωτευων "who loveth the presidency," or chief place, doubtless in the church, of which Diotrephes was most probably an officer; and being one, magnified himself in his office: he loved such pre-eminence, and behaved haughtily in it. Mat 20:20-28, Mat 23:4-8; Mar 9:34, Mar 10:35-45; Luk 22:24-27; Rom 12:10; Phi 2:3-5; Tit 1:7-16 receiveth: Jo3 1:8; Mat 10:40-42; Mar 9:37; Luk 9:48 3 John 1:10”
