Introduction
The Third Letter of John may be one of the shortest in the New Testament, but its message carries immense weight.
It’s a warm yet candid pastoral note—a “straight from the shoulder” letter from someone with deep spiritual insight. Where encouragement is due, it is generously given. Where there is spiritual failure, it is not excused or ignored.
The author introduces himself not as “the Apostle John,” but simply as “the elder.” His reputation and spiritual authority were so well established in the early church—especially among believers in Asia Minor—that this simple title sufficed.
Background
Likely written in his later years while residing in Ephesus, John had become a shepherd and overseer to a network of churches. His voice carried weight, not just because of his age, but because he was the last surviving Apostle of Christ—a living link to Jesus Himself.
Text
In this short letter, John offers a rare and honest appraisal of three individuals: Gaius, Diotrephes, and Demetrius.
What makes this remarkable is that these spiritual evaluations are not private or sealed—they have been preserved and published in Scripture for all time. These assessments provide a mirror in which every Christian may examine themselves.
Just as executives assess employees or teachers write end-of-term reports, John writes spiritual assessments. But his “report” has eternal significance.
Scripture
The Bible reminds us that one day each of us will stand before Christ, and our lives and service will be openly evaluated (2 Cor.5:10). Paul describes this coming test in terms of quality: some works will be like gold, silver, and precious stones, while others will amount to wood, hay, and stubble (1 Cor. 3:12). What survives the fire of God’s judgment will be rewarded. What does not will be burned away.
John’s brief letter gives us a kind of preview exam. We are given the chance to learn from the examples he names—both positive and negative. His assessments are not mere history; they are spiritual case studies that apply to us all.
Gaius: The Servant Who Strengthens Others
John begins with Gaius, a beloved member of the church. Several men named Gaius appear in the New Testament, but the one in this letter is known chiefly for his hospitality and spiritual health.
John addresses him with warmth: “Dear friend, I pray that you may enjoy good health and that all may go well with you, even as your soul is getting along well” (v. 2). This small prayer reveals a great truth—Gaius may have faced physical challenges, but his soul was flourishing. Gaius is a model of spiritual vitality. He is known for walking in the truth and faithfully supporting traveling gospel workers. Others returned to John with glowing reports about his generosity and love. He embodied what it meant to serve the church—not for show, but from a heart aligned with the truth.
This kind of “soul health” is what Jesus desires for all His followers. He came so that we might “have life, and have it abundantly” (John 10:10). Gaius lived that kind of life—a life not endured but enjoyed through fellowship with Christ and in service to others.
Diotrephes: The Divider Who Hinders Others
In stark contrast to Gaius, John introduces Diotrephes (vv. 9–11), a man whose name has become synonymous with spiritual pride and church division.
We know little about him outside of this letter, but the few verses speak volumes.
Diotrephes is described as one who “loves to be first.” He rejects apostolic authority, refuses to welcome gospel workers, gossips maliciously about John, and even expels faithful members from the church.
Six traits stand out in Diotrephes:
- He craved recognition.
He wanted to be the central figure in church life. All decisions, all plans, all recognition—he wanted them to flow through him.
- He rejected authority.
He refused to acknowledge John’s leadership and likely destroyed a previous letter from the Apostle.
- He opposed gospel work.
Instead of welcoming traveling preachers, he blocked them and punished those who tried to help.
- He slandered fellow believers. Using malicious words, he tore down those he saw as threats.
- He abused power.
He excommunicated those who didn’t align with his views, causing deep division.
- He lived for self, not Christ. Though he had every opportunity to be a godly leader, his legacy is one of pride and damage.
Diotrephes is a warning. Even today, churches often face problems when certain individuals seek power and control instead of serving Christ. This kind of leadership can harm the church and cause division. In 1 Corinthians 3:4–8, 21–22, the Apostle Paul reminds us that all church leaders are equal. He teaches that the church belongs to Christ—not to its leaders—and is greater than any one minister. Paul does not give Peter (Cephas) or any other leader special authority over the church. Instead, he says, “All things are yours—whether Paul or Apollos or Cephas.” In other words, no minister should act like the boss or place human authority above God’s Word.
The above truth is also emphasized in The Book of Concord, the foundational teachings of the Lutheran Church. It teaches that no leader has the right to rule over the church, burden it with human traditions, or demand obedience beyond what the Bible teaches
St. John offers wise counsel: “Do not imitate what is evil but what is good” (v. 11). We are not called to confront Diotrephes with more pride or power struggles—but with humility, clarity, and Christ-centered conviction.
Demetrius: The Disciple Who Attracts Others
Finally, John commends Demetrius (v. 12). While less is said about him, it is all positive. He has “a good testimony from everyone,” and even John affirms his consistent character. His life matches the truth he professes.
Where Gaius served and Diotrephes sought status, Demetrius simply lived the truth. His faithful walk attracted others, bringing unity rather than division. He reminds us that the most powerful testimony is not always in words, but in a consistent, Christ-honouring life.
Conclusion: Whose Example of Faith Will We Follow?
John’s letter to Gaius is more than a personal note; it is a timeless spiritual evaluation. Three men—three very different legacies:
- Gaius: a servant whose faith and hospitality built up the body of Christ.
- Diotrephes: a divisive leader whose pride and control tore the church apart.
- Demetrius: a steady disciple whose integrity and love inspired trust and unity.
Each of us reflects one of the three people John wrote about—Gaius, Diotrephes, or Demetrius—in some way. If the Elder were to evaluate us today, what would he see? When our lives are evaluated by Christ, what will remain? Will our legacy be one of loving service, or will it show selfishness and division?
In today’s world, when we are called to speak the truth—especially in difficult or controversial situations—we must do so with wisdom, humility, and care. The peace that John wished for Gaius is the kind of peace that only Christ can give—a deep and lasting peace that the world cannot take away.
May we learn from these examples of FAITH and live in such a way that, when our time of judgment comes, the Lord will say to us: “Well done, good and faithful servant.”
Prayer
Heavenly Father, You have called each of us by name through Baptism into Your Son, Jesus Christ. Grant us the peace that surpasses all understanding—a peace the world cannot give and that self-centred hearts cannot grasp. Keep us in this perfect peace, the peace of Christ, until the day we no longer need to read Your Word in written form, for then we shall see the Living Word—our Lord Jesus—face to face.
Amen.
