3 John 1

The Elder writes to Gaius to commend his hospitality toward itinerant believers and to warn him against the exclusionary, self-serving behavior of a church member named Diotrephes. This brief epistle links a Christian's 'walk in the truth' directly to their support for those who carry the gospel.

• The Elder offers a warm greeting to Gaius, praying for his physical health to match his spiritual prosperity.
• The Elder commends Gaius for his faithful hospitality, noting that he supports both known brethren and strangers.
• The Elder exposes the arrogant, schismatic behavior of Diotrephes, who refuses to host believers and intimidates those who do.
• The Elder exhorts Gaius to imitate what is good, using Demetrius as a positive example of one who is well-regarded by the truth.
• The letter closes with a desire for face-to-face communication, delaying further details until they can meet.

• Walking in truth
• Hospitality vs. exclusion

3 John provides a vital apostolic standard for church hospitality and leadership, demonstrating that how a believer treats God's servants is a direct reflection of their devotion to the truth. It serves as a necessary check against the abuse of church authority for personal prominence.

A life defined by 'truth' (ἀλήθεια) is evidenced not in abstract belief, but in practical, sacrificial support for those who represent Christ.

The epistle follows a pattern of contrasts: praise for the faithful (Gaius/Demetrius) surrounds a warning against the unfaithful (Diotrephes), all unified by the central theme of 'walking in the truth.'

• If thou bring forward on their journey after a godly sort, thou shalt do well (3 John 1:6)

• Follow not that which is evil, but that which is good (3 John 1:11)

• He that doeth evil hath not seen God (3 John 1:11)

• The early church relied on the hospitality of local believers to support itinerant missionaries who relied on no outside funding.
• The term 'Elder' (πρεσβύτερος, G4245) indicates a position of apostolic or church authority, common to the Johannine literature.

• In the ancient Greco-Roman world, the provision of hospitality to strangers and travelers was a moral obligation; the author applies this standard to Christian community life.
• Letters like this were often circulated among house churches, making the public critique of Diotrephes a significant act of church discipline.

• The letter functions as the practical counterpart to 2 John; whereas 2 John warns against showing hospitality to false teachers, 3 John commands hospitality for faithful ones.
• The letter is brief and personal, designed to be supplemented by an anticipated face-to-face meeting.

• The emphasis on 'walking' (περιπατέω, G4043) echoes the Johannine emphasis on the active life of faith (cf. 1 John 2:6, 2 John 6).
• Matthew Henry observes: '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.'

• The phrases 'walking in truth' (3 John 3-4) and 'truth that is in thee' (3 John 3) are linguistic mirrors of 2 John 4.

• πρεσβύτερος (presbýteros, G4245): 'Elder' or 'older,' denoting the author's recognized leadership position in the community.
• ἀλήθεια (alḗtheia, G225): 'Truth,' central to John’s theology; it is not merely intellectual, but something one can 'walk' (περιπατέω, G4043) in.
• μαρτυρέω (martyréō, G3140): 'Testified' or 'witnessed'; vital for verifying the integrity of both Gaius and Demetrius.

• The tension between the authority of the Elder and the local autonomy of Diotrephes; this text is often cited in discussions regarding the nature of ecclesiastical authority vs. congregational or local leadership.
• The author does not use his apostolic authority to unilaterally remove Diotrephes, but promises to 'remember his deeds' if he comes (v. 10), indicating a process of face-to-face confrontation.

• The identity of 'The Elder' is traditionally attributed to the Apostle John, though some scholars debate this based on the specific title.
• The nature of the 'preeminence' (v. 9) Diotrephes seeks is debated: some see it as a power struggle over church leadership, others as a clash over the authority of the Elder vs. the local church.
