John is writing with his usual strong emphasis on truth to this much-loved brother in Christ, Gaius, a layman of some wealth and distinction in a city near Ephesus. He highly commends Gaius' care and hospitality to his messengers whose mission was to take the Gospel from place to place, whether they were known to him or were strangers. John exhorts him to continue to to do good and not to imitate evil, as in the example of Diotrephes. This man had taken over the leadership of a church in Asia and not only refused to recognize John’s authority as an apostle but also refused to receive his letters and submit to his directions. He also circulated malicious slanders against John and excommunicated members who showed support and hospitality to John’s messengers. Before John concludes his letter, he also commends the example of Demetrius, of whom he has heard excellent reports.
Chapters - Kapitulo
The concept of offering hospitality to strangers has plenty of precedent in the Old Testament. Acts of hospitality in Israel included the humble and gracious reception of aliens into the home for food, lodging, and protection (Genesis 18 : 2 – 8, 19 : 1 – 8; Job 31 : 16 – 23, 31 – 32). In addition, Old Testament teaching portrays the Israelites as alienated people who are dependent on God’s hospitality (Psalm 39 : 12) and God as the One who graciously meets their needs, redeeming them from Egypt and feeding and clothing them in the wilderness (Exodus 16; Deuteronomy 8 : 2 – 5).
John’s purpose in writing this third epistle is threefold. First, he writes to commend and encourage his beloved co-worker, Gaius, in his ministry of hospitality to the itinerant messengers who were going from place to place to preach the Gospel of Christ. Second, he indirectly warns and condemns the behavior of one Diotrephes, a dictatorial leader who had taken over one of the churches in the province of Asia, and whose behavior was directly opposed to all that the apostle and his Gospel stood for. Third, he commends the example of Demetrius who was reported as having a good testimony from all.
