(1) The elder.--See the Introduction, and 2John 1:1.

Gaius.--The common Roman name Caius. A Caius is mentioned in Acts 19:29; Acts 20:4; Romans 16:23; 1Corinthians 1:14. The difference in date between these and St. John's correspondent would alone be sufficient reason against any attempt at identification. There is nothing to show whether he was a presbyter or not.

Whom I love in the truth.--Or, in truth. (See 2John 1:1.)

Verse 1. - To Gaius the beloved (Γαι'´ῳ τῷ ἀγαπητῷ). This is additional reason for thinking that κυρία in the Second Epistle is not a proper name; if it were we should probably have the same formula as we have here, Κυρίᾳ τῇ ἐκλεκτῇ. The name Gaius occurs elsewhere in the New Testament four times (Acts 19:29; Acts 20:4; Romans 16:23; 1 Corinthians 1:14); as it was as common in the Roman Empire as John Smith is among ourselves, it would be rash to infer that the Gaius addressed here is the same as any of those mentioned elsewhere. In all probability there are at least four persons of this name in the New Testament. In the opening of this Epistle also we have to remark the characteristic repetition of the word "truth," which occurs four times in the first four verses. Deeds, in which Gaius and Demetrius were rich, not words, of which Diotrephes was so prodigal, are what win the approbation and love of the apostle. The thing which he hates is unreality; the object of his special adoration is "the truth;" "to walk in the truth" is nothing less than to follow in the footsteps of the Lord.

1:1-8 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.The elder unto the well beloved Gaius,.... The elder is the writer of the epistle, the Apostle John, who so styles himself on account of his age, and office, as in the preceding epistle. The person to whom he writes is "the well beloved Gaius"; not that Gaius, who was the Apostle Paul's host, Romans 16:23, for though their characters agree, being both hospitable men, yet neither the place nor time in which they lived. The Apostle Paul's Gaius lived at Corinth, this is in some place near to Ephesus, for the apostle in his old age purposed to come and see him shortly; the other was contemporary with Paul, this with John; there were thirty or forty years difference between them: besides, the Corinthian Gaius was baptized by Paul, and was doubtless one of his spiritual children, or converts, whereas this Gaius was one of the Apostle John's spiritual children, 3 John 1:4; nor does he seem to be the same with Gaius of Macedonia, Acts 19:29, or with Gaius of Derbe, Acts 20:4, who seem to be two different persons by their country, though both companions in travel of the Apostle Paul; for which reason, as well as the time of their living, neither of them can be this Gaius, who was a settled housekeeper, and resided at some certain place. His name is a Roman name, and the same with Caius, though he seems to have been a Jew, as he might, it being usual with the Jews in other countries to take Gentile names. His character is, that he was "well beloved"; that is, of God, as it appears he was from the grace bestowed on him, from the prosperous estate of his soul, and from the truth that was in him, and his walking in it; and of the Lord Jesus Christ, for the same reasons; and also of all the brethren and saints that knew him; he being a person not only truly gracious, and of faithfulness and integrity, but of great liberality and beneficence, which must gain him much love and esteem among them; and he was well beloved by the Apostle John; and so the Syriac version renders it, "to my beloved Gaius": though his love to him is expressed in the following clause,

whom I love in the truth; as being in it, or for the sake of it, or truly and sincerely; See Gill on 2 John 1:1.
