The parts of this Epistle are also three. First, a preface (3 John 1, 2). Second, the treatment, that is, commendation on account of the acknowledgement of the truth, and an exhortation to constancy and beneficence, etc. (3 John 3-12). Third, the conclusion (3 John 13, 14).
I. The Preface of the Epistle, verses 1, 2.
For beloved Gaius, having a sound mind, he prays prosperity in every thing else also: verses 1, 2.
II. The treatment, that is, a commendation of the faith and beneficence of Gaius, a reprehension of Diotrephes, and praise of Demetrius, verses 3-12.
He expresses his joy over Gaius’ faith (verses 3, 4) and charity towards the brethren, witnessed by those going forth on account of the name of Christ (verses 5-8); rendering a reason why he wrote to him, not to the Church, namely, because Diotrephes does not receive him, whom he marks and advises to flee (verses 9-11), contrariwise commending Demetrius (verse 12): verses 3-12.
III. The Conclusion, verses 13, 14.
Excusing his brevity, he promises to come, and closes with prayer (verses 13, 14): verses 13, 14.
