The elder unto the wellbeloved Gaius, whom I love in the truth.

Beloved, I wish above all things that thou mayest prosper and be in health, even as thy soul prospereth.

For I rejoiced greatly, when the brethren came and testified of the truth that is in thee, even as thou walkest in the truth.

I have no greater joy than to hear that my children walk in truth.

Beloved, thou doest faithfully whatsoever thou doest to the brethren, and to strangers;

Which have borne witness of thy charity before the church: whom if thou bring forward on their journey after a godly sort, thou shalt do well:

Because that for his name's sake they went forth, taking nothing of the Gentiles.

We therefore ought to receive such, that we might be fellowhelpers to the truth.

I wrote unto the church: but Diotrephes, who loveth to have the preeminence among them, receiveth us not.

10 Wherefore, if I come, I will remember his deeds which he doeth, prating against us with malicious words: and not content therewith, neither doth he himself receive the brethren, and forbiddeth them that would, and casteth them out of the church.

11 Beloved, follow not that which is evil, but that which is good. He that doeth good is of God: but he that doeth evil hath not seen God.

12 Demetrius hath good report of all men, and of the truth itself: yea, and we also bear record; and ye know that our record is true.

13 I had many things to write, but I will not with ink and pen write unto thee:

14 But I trust I shall shortly see thee, and we shall speak face to face. Peace be to thee. Our friends salute thee. Greet the friends by name.

Commentary

Verse 1

Matthew Henry's Concise Bible Commentary
The apostle commends Gaius for piety and hospitality.
Those who are beloved of Christ, will love the brethren for his sake. Soul prosperity is the greatest blessing on this side heaven. Grace and health are rich companions. Grace will employ health. A rich soul may be lodged in a weak body; and grace must then be exercised in submitting to such a dispensation. But we may wish and pray that those who have prosperous souls, may have healthful bodies; that their grace may shine where there is still more room for activity. How many professors there are, about whom the apostle's words must be reversed, and we must earnestly wish and pray that their souls might prosper, as their health and circumstances do! True faith will work by love. A good report is due from those who receive good; they could not but testify to the church, what they found and felt. Good men will rejoice in the soul prosperity of others; and they are glad to hear of the grace and goodness of others. And as it is a joy to good parents, it will be a joy to good ministers, to see their people adorn their profession. Gaius overlooked petty differences among serious Christians, and freely helped all who bore the image, and did the work of Christ. He was upright in what he did, as a faithful servant. Faithful souls can hear their own praises without being puffed up; the commendation of what is good in them, lays them at the foot of the cross of Christ. Christians should consider not only what they must do, but what they may do; and should do even the common actions of life, and of good-will, after a godly sort, serving God therein, and designing his glory. Those who freely make known Christ's gospel, should be helped by others to whom God gives the means. Those who cannot themselves proclaim it, may yet receive, help, and countenance those who do so.
John Wesley's Bible Commentary
Caius was probably that Caius of Corinth whom St. Paul mentions, (Romans 16:23) . If so, either he was removed from Achaia into Asia, or St. John sent this letter to Corinth.
McArther Bible Commentary
The Elder. John uses the same term for himself as he did in 2Jn 1:1. The term probably has reference to his age, his apostolic eyewitness status of Jesus' life, and also that he had an official position of authority in the church. the beloved. The term beloved is only used of Christians in the NT (Col 3:12; Phm 1:1-2; 2Pe 3:14; 1Jn 4:1). Gaius. Nothing is known of Gaius beyond the mention of his name in the salutation. The name was one of eighteen common names from which Roman parents usually chose a name for one of their sons, making any specific identification doubtful. John, his fellow believers, and even strangers to whom Gaius extended hospitality held him in great esteem for his Christian walk and conduct (3Jn 1:1-6). John conveyed his own appreciation for Gaius by calling him "beloved" four times in the letter (3Jn 1:1-2, 3Jn 1:5, 3Jn 1:11). He probably was a member of a church somewhere in Asia Minor that was under John's sphere of influence. The apostle planned to visit him sometime in the near future (3Jn 1:13). whom I love in truth. Because Christians have common knowledge of the truth, they have the common source of love (2Jn 1:1). While some have taken the phrase to mean simply "truly" or "really" (Mar 12:32; Joh 1:47), John's usage of this phrase elsewhere in these letters, where truth takes on such a significant meaning, suggests that the elder intended the kind of love that is consistent with the fundamental truths of the faith (cf. 3Jn 1:4; 1Jn 2:21; 1Jn 3:19).

McArther Bible Commentary
I pray. John's prayer for Gaius is significant. Gaius's spiritual state was so excellent that John prayed that his physical health would match his spiritual vigor. To ask about one's health was standard custom in ancient letters, but John adapted this convention in a unique manner to highlight Gaius's vibrant spiritual state.

His spiritual reputation was well known. you walk in the truth. Gaius's reputation for practicing what he preached was exemplary (2Jn 1:4). John's commendation of him is one of the greatest given in the NT, since the commendation centers not only on the fact that he knew the truth, but that he faithfully practiced it. Gaius's actions were in stark contrast to Diotrephes's negative reputation (3Jn 1:10).

John Wesley's Bible Commentary
They went forth - To preach the gospel.
McArther Bible Commentary
John gives several grounds for practicing hospitality in a "manner worthy of God." First, one must show hospitality to those who have pure motives. These itinerant missionaries went out "for the sake of the name" (3Jn 1:7; cf. Rom 1:5). They must be doing their ministry for God's glory, not their own. Second, one must show hospitality to those who are not in ministry for money. Since the missionaries were "taking nothing from the Gentiles" (3Jn 1:7), the church was their only means of support. They were free from avarice (2Co 2:17; 1Ti 5:17-18). Third, those who show hospitality participate in the ministries of those to whom hospitality is shown (3Jn 1:8). Verse 3Jn 1:8 gives the same reason to demonstrate hospitality to genuine teachers, as does 2Jn 1:10, in forbidding hospitality toward false teachers, i.e., that those who extend hospitality share in the deeds (i.e., good or bad) of those receiving it.

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!
McArther Bible Commentary
I wrote to the church. John apparently had written a previous letter to the church, perhaps on the subject of hospitality, but it was lost. Perhaps, Diotrephes never read it to the church because he rejected John's authority (cf. 3Jn 1:9-10). Diotrephes, who loves to have the preeminence. In the second part of his epistle, John condemned the violation of hospitality toward faithful ministers of the Word. The word preeminence has the idea of "desiring to be first." It conveys the idea of someone who is selfish, self-centered, and self-seeking. The language suggests a self-promoting demagogue, who served no one, but wanted all to serve only him. Diotrephes's actions directly contradict Jesus' and the NT's teaching on servant-leadership in the church (cf. Mat 20:20-28; Php 2:5-11; 1Ti 3:3; 1Pe 5:3). does not receive us. Diotrephes modeled the opposite of kindness and hospitality to God's servants, even denying John's apostolic authority over the local congregation and, as a result, denying the revelation of God that came through that authority. His pride endeavored to supplant the rule of Christ through John in the church. Diotrephes's character was the very opposite of the gentle and loving Gaius, who readily showed hospitality.

He prateth against us - Both them and me, thereby endeavouring to excuse himself.
McArther Bible Commentary
if I come, I will call to mind his deeds. John's apostolic authority meant that Diotrephes had to answer for his behavior. The apostle did not overlook this usurping of Christ's place in the church. Verse 3Jn 1:10 indicates that Diotrephes was guilty of four things: (1) "prating against us." The word prating comes from a word meaning "to bubble up" and has the idea of useless, empty jabber (i.e., talking nonsense). The charges against John were completely unjustified; (2) "with malicious words." Not only were Diotrephes's charges false, they were evil; (3) "does not receive the brethren." He not only slandered John, but also deliberately defied other believers; and (4) "putting them out of the church." The original language indicates that Diotrephes' habit was to excommunicate those who resisted his authority. does not receive the brethren. To accept John's authority (3Jn 1:9), as well as being hospitable to the traveling ministers, directly threatened the authority that Diotrephes coveted.

do not imitate what is evil, but what is good. The verse begins the introduction to the commendation of Demetrius in verse 3Jn 1:12. Gaius was to imitate Demetrius as the correct role model for his actions. He who does good is of God, but he who does evil has not seen God. John's statement indicates that Diotrephes's actions proved that he was never a Christian. This is a practical application of the moral test (see notes on 1Jn 5:2-3).

Happy those whose spirit and conduct commend them before God and men. We must be ready to bear our testimony to them; and it is well when those who commend, can appeal to the consciences of such as know most of those who are commended. A personal conversation together often spares time and trouble, and mistakes which rise from letters; and good Christians may well be glad to see one another. The blessing is, Peace be to you; all happiness attend you. Those may well salute and greet one another on earth, who hope to live together in heaven. By associating with and copying the example of such Christians, we shall have peace within, and live at peace with the brethren; our communications with the Lord's people on earth will be pleasing, and we shall be numbered with them in glory everlasting.

Here is the character of Demetrius. A name in the gospel, or a good report in the churches, is better than worldly honour. Few are well spoken of by all; and sometimes it is ill to be so. Happy those whose spirit and conduct commend them before God and men. We must be ready to bear our testimony to them; and it is well when those who commend, can appeal to the consciences of such as know most of those who are commended. A personal conversation together often spares time and trouble, and mistakes which rise from letters; and good Christians may well be glad to see one another. The blessing is, Peace be to you; all happiness attend you. Those may well salute and greet one another on earth, who hope to live together in heaven. By associating with and copying the example of such Christians, we shall have peace within, and live at peace with the brethren; our communications with the Lord's people on earth will be pleasing, and we shall be numbered with them in glory everlasting.
John Wesley's Bible Commentary
Salute the friends by name - That is, in the same manner as if I had named them one by one. The word friend does not often occur in the New Testament, being swallowed up in the more endearing one of brother.
