Matthew Henry commentary on 3 John 1:2-4
Christian communion is exerted and cherished by letter. Christians are to be commended in the practical proof of their professed subjection to the gospel of Christ. The animating and countenancing of generous and public-spirited persons is doing good to many—to this end the apostle sends this encouraging epistle to his friend Gaius, in which also he complains of the quite opposite spirit and practice of a certain minister, and confirms the good report concerning another more worthy to be imitated.
In this epistle the apostle congratulates Gaius upon the prosperity of his soul ( ver. 1, 2 ), upon the fame he had among good Christians ( ver. 3, 4 ), and upon his charity and hospitality to the servants of Christ, ver. 5, 6 . He complains of contemptuous treatment by an ambitious Diotrephes, ( ver. 9, 10 ), recommends Demetrius, ( ver. 12 ), and expresses his hope of visiting Gaius shortly, ver. 13, 14 .
Salutation and Prayer. ( a. d. 90.)
Embedded KJV/source Scripture
1 The elder unto the wellbeloved Gaius, whom I love in the truth. 2 Beloved, I wish above all things that thou mayest prosper and be in health, even as thy soul prospereth.
Here we see, I. The sacred penman who writes and sends the letter; not here indeed notified by his name, but a more general character: The elder, he that is so by years and by office; honour and deference are due to both. Some have questioned whether this were John the apostle or no; but his style and spirit seem to shine in the epistle. Those that are beloved of Christ will love the brethren for his sake. Gaius could not question from whom the letter came. The apostle might have assumed many more illustrious characters, but it becomes not Christ's ministers to affect swelling pompous titles. He almost levels himself with the more ordinary pastors of the church, while he styles himself the elder. Or, possibly, most of the extraordinary ministers, the apostles, were now dead, and this holy survivor would countenance the continued standing ministry, by assuming the more common title—the elder. The elders I exhort, who am also an elder, 1 Pet. v. 1 .
II. The person saluted and honoured by the letter. The former is directed to an elect lady, this to a choice gentleman; such are worthy of esteem and value. He is notified, 1. By his name,— Gaius. We read of several of that name, particularly of one whom the apostle Paul baptized at Corinth, who possibly might be also the apostle's host and kind entertainer there ( Rom. xvi. 23 ); if this be not he, it is his brother in name, estate, and disposition. Then, 2. By the kind expressions of the apostle to him: The well-beloved, and whom I love in the truth. Love expressed is wont to kindle love. Here seems to be either the sincerity of the apostle's love or the religion of it. The sincerity of it: Whom I love in the truth, for the truth's sake, as abiding and walking in the truth as it is in Jesus. To love our friends for the truth's sake is true love, religious gospel love.
The Character of Gaius. ( a. d. 90.)
Embedded KJV/source Scripture
3 For I rejoiced greatly, when the brethren came and testified of the truth that is in thee, even as thou walkest in the truth. 4 I have no greater joy than to hear that my children walk in truth. 5 Beloved, thou doest faithfully whatsoever thou doest to the brethren, and to strangers; 6 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: 7 Because that for his name's sake they went forth, taking nothing of the Gentiles. 8 We therefore ought to receive such, that we might be fellowhelpers to the truth.
In these verses we have,
I. The good report that the apostle had received concerning this friend of his: The brethren came and testified of the truth that is in thee ( v. 3 ), who have borne witness of thy charity before the church, v. 6 . Here we may see, 1. The testimony or thing testified concerning Gaius—the truth that was in him, the reality of his faith, the sincerity of his religion, and his devotedness to God; and this evinced by his charity, which includes his love to the brethren, kindness to the poor, hospitality to Christian strangers, and readiness to accommodate them for the service of the gospel. Faith should work by love; it gives a lustre in and by the offices of love, and induces others to commend its integrity. 2. The witnesses-brethren that came from Gaius testified and bore witness. A good report is due from those who have received good; though a good name is but a small reward for costly service, yet it is better than precious ointment, and will not be refused by the ingenuous and religious. 3. The auditory or judicatory before which the report and testimony were given— before the church. This seems to be the church at which the apostle now resided. What church this was we are not sure; what occasion they had thus to testify his faith and love before the church we cannot tell; possibly out of the fulness of the heart the mouth spoke; they could not but testify what they found and felt; possibly they would engage the church's prayer for the continued life and usefulness of such a patron, that he might prosper and be in health as his soul prospered.
II. The report the apostle himself gives of him, introduced by an endearing appellation again: Beloved, thou doest faithfully whatsoever thou doest to the brethren, and to strangers, v. 5 . 1. He was hospitable, good to the brethren, even to strangers; it was enough to recommend them to Gaius's house that they belonged to Christ. Or he was good to the brethren of the same church with himself, and to those who came from far; all who were of the household of faith were welcome to him. 2. He seems to have been of a catholic spirit; he could overlook the petty differences among serious Christians, and be communicative to all who bore the image and did the work of Christ. And, 3. He was conscientious in what he did: " Thou doest faithfully (thou makest faithful work of) whatsoever thou doest; thou doest it as a faithful servant, and from the Lord Christ mayest thou expect the reward of the inheritance." Such faithful souls can hear their own praises without being puffed up; the commendation of what is good in us is designed, not for our pride, but for our encouragement to continue therein, and should be accordingly improved.
