I.Diotrephes, unlike Gaius, loved preeminence and refused apostolic authority, spreading malicious words. He did not accept John’s letter and discouraged others from showing hospitality, casting them out of the church. John warns that he will address this behavior when he visits. II. John cautions against following Diotrephes’ evil example and encourages believers to imitate what is good, for those who do good are of God, while those who do evil have not seen God.

I wrote unto the Church - The Church where Caius was; but Diotrephes, who loveth to have the pre-eminence, φιλοπρωτευων, who loves the presidency, or chief place in the Church. He was doubtless an officer in the Church, at least a deacon, probably a bishop; and, being one, he magnified himself in his office; he loved such eminence, and behaved himself haughtily in it.

Receiveth us not - Does not acknowledge the apostolical authority. As some MSS. supply αν after εγραψα, and several judicious critics believe it is implied, the translation will run thus: I would have written to the Church to receive these men kindly, but Diotrephes, who affects the presidency; and into whose hands, if I wrote to the Church, my letter must come, receiveth us not - would not acknowledge my authority to interfere with any of the matters of his Church; and therefore I have written unto thee, whose love to the brethren and general hospitality are well known, that thou wouldst receive those strangers and persecuted followers of our common Lord.

I wrote unto the church,.... 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 church"; upon this head, concerning receiving and supporting ministers of the Gospel, and so prevents an objection that Gaius might make, why did he not write to the church about it? The Vulgate Latin version reads, "I should", or "would have wrote": and the Syriac version, "I desired", or "wished to have wrote"; suggesting, that though he had not wrote, yet it was much upon his mind, he had a great desire to it:

but Diotrephes, who loveth to have the preeminence among them,

receiveth us not; which hindered him from writing, or was the reason why he wrote now to Gaius since Diotrephes gave no heed to what he had wrote, suppressed his letter, and would not suffer it to be read to the brethren. This Diotrephes, by his name, which signifies one "nourished", or "brought up by Jupiter", was a Gentile; there was one of this name, who was one of the kings of Athens (a); and what may confirm this is, his slighting and rejecting the brethren that came from Judea: it is very likely he was more than a private member in the church, and that he was an officer, and it may be the pastor; and though there is a preeminence, which of right belongs to such an officer, as to preside over the church, to govern, guide, and direct, according to the laws of Christ, he being set over the church, as a ruler, governor, and guide; yet this may be carried too far, as it was by this man, who coveted more than was his due, and lorded it over God's heritage, ruled the flock with force and cruelty, and usurped a tyrannical power over them; whereas every thing in a church ought to be done, by pastor and people, in love, meekness, and with mutual consent. And it may be also, that he sought to have the preeminence over the rest of the elders of the church, for in those large churches there were oftentimes more elders and pastors than one; see Act 20:17. This ambitious spirit prevailed and obtained among the false teachers, who set up themselves at the head of parties, and above the apostles of Christ, and paved the way for antichrist, who assumed the title of universal bishop, which has introduced all the errors and impieties of the Romish church. Now this man such an ambitious, lordly, and governing spirit, received not the Apostle John, and those that were with him; meaning not their persons, for as yet he and they were not in person where he was; but his letter, his orders, and instructions; these he paid no regard to, concealed them from the church, and would not admit them to be read: or else the apostle's sense is, that he received not the brethren that came from him, and were recommended by him, and whom he affectionately loved, and who were near and dear to him as himself; and therefore not receiving them is interpreted by him as not receiving himself.

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).
