The brief letter addressed to us through Gaius offers a vivid snapshot of life in an early house church, where hospitality and leadership bore witness to the gospel. John commends Gaius for walking in truth and showing generous hospitality to traveling missionaries, “supporting such ones so that we become coworkers with the truth” (3 John 1:8). This echoes Jesus’ call to care for “the least of these” by welcoming strangers—“I was a stranger and you welcomed me” (Matthew 25:35)—and reflects the servant-hearted example He set when He washed His disciples’ feet (John 13:14–15).
In contrast, John rebukes Diotrephes, who loves preeminence and expels those who receive the brothers, highlighting how selfish ambition undermines unity and love. This mirrors Jesus’ warning about those who “loved the glory that comes from man” rather than the glory from God (John 5:44). John urges us to imitate what is good, to follow the pattern of Demetrius, who carries a good testimony before both church and world.
As we reflect on this letter, we’re challenged to uphold truth through humble service and to reject domineering leadership. May our communities be marked by generous welcome, mutual support, and faithful partnership in the work of the gospel.
