Background of 3 John

Authorship and Date

The author of 3 John identifies himself simply as “the elder” in verse 1. While this makes the letter anonymous, most scholars believe this was the apostle John based on writing style and themes that are similar to the Gospel of John and 1 John.

The precise date of composition is unknown, but is likely between A.D. 85-95, toward the end of John’s life.

The main themes of 3 John echo John’s other writings, with an emphasis on walking in truth, love, and obedience. The author also deals with the problem of traveling teachers who have gone out “for the sake of the Name” (v. 7) but require financial support from believers.

This indicates 3 John was likely written after the establishment of a network of churches in Asia Minor that needed encouragement and guidance.

Recipients and Setting

The letter is addressed to “dear friend Gaius” (v. 1), presumably a leader in one of the churches under John’s oversight. The name Gaius was very common, so it’s unknown if he is the same Gaius associated with Paul mentioned in Acts 19:29, 20:4, Romans 16:23, and 1 Corinthians 1:14.

John commends Gaius for his hospitality in welcoming and supporting traveling teachers, in contrast to Diotrephes, who “loves to be first” and refuses to welcome these brothers (v. 9). The letter indicates strained relationships between church leaders over financial support and hospitality for itinerant preachers, a relatively common issue in the early decades of the church.

The traveling teachers likely depended on support from churches they visited, following Jesus’ instructions in Matthew 10:10. However, some took advantage of generosity, sparking debate over who should be supported.

John affirms Gaius for supporting faithful teachers and condemns Diotrephes for his pride and hostility.

Purpose and Themes of 3 John

The purpose of 3 John is to encourage Christians to live faithfully and show hospitality to fellow believers, even in the face of opposition. The key themes of this short but powerful book include:

Hospitality and Support for Fellow Christians

John commends Gaius for his hospitality and support shown to fellow traveling teachers and missionaries. Even though Gaius was likely not well-off financially, he generously opened his home and resources to these brothers and sisters in Christ (3 John 1:5-8).

John encourages the practice of hospitality within the church.

Walking in the Truth

John affirms the importance of “walking in the truth” – living according to God’s commands and sound doctrine. He commends Christians like Gaius who are faithfully living out their faith (3 John 1:3-4).

Imitating Good and Rejecting Evil

John draws a contrast between good role models like Gaius, Demetrius, and himself with bad role models like Diotrephes. He encourages the readers to “imitate good” and warns them to reject prideful and selfish leaders like Diotrephes who create division in the church (3 John 1:9-11).

Standing Firm in the Face of Opposition

John indicates that showing hospitality and living righteously does not always lead to praise and comfort. Gaius and Demetrius likely faced criticism and opposition from powerful leaders like Diotrephes for supporting the traveling ministers (3 John 1:9-10).

John encourages them to stand firm in the truth despite adversity.

In just 304 words, John powerfully calls all Christians to faithfully follow Jesus, serve others, reject ungodly teaching, and persevere through trials. His message remains deeply relevant today.

Structure and Content Summary of 3 John

The third epistle of John, commonly referred to as 3 John, is the shortest book in the Bible. Despite its brevity, 3 John provides valuable insight into early Christianity.

Outline and Structure

3 John follows a typical epistle format with an opening greeting, a body, and a closing farewell. The book can be divided into four sections:

  1. The greeting from “the elder” to his “dear friend Gaius” (verse 1)
  2. Commendation of Gaius for his hospitality and faithfulness (verses 2-8)
  3. Condemnation of Diotrephes who loves preeminence and refuses hospitality (verses 9-11)
  4. The elder’s intentions to visit Gaius and conclusion (verses 12-14)

Content Summary

In the greeting, the author identifies himself only as “the elder”, possibly due to his old age and position within the church. He writes to his dear friend Gaius, of whom little else is known. The elder expresses his appreciation for Gaius’s loyalty to the truth and commends him for providing hospitality to fellow believers, even though they were strangers.

In contrast, Diotrephes, another leader in the church, is condemned for refusing to welcome the brothers and fellow workers arriving from the elder. Diotrephes even goes as far as to hinder and expel anyone who assists these visitors.

The elder condemns this behavior and vows to confront Diotrephes face-to-face.

The central tension in 3 John revolves around showing hospitality to those spreading the Gospel. Gaius represents the ideal example of welcoming visitors, supporting their mission, and sending them on their way, while Diotrephes embodies hostility and a lust for preeminence.

In the conclusion, the author indicates his plans to visit Gaius and other believers soon. He closes with a wish for peace and a final greeting from friends.

Key Themes

Some of the key themes in 3 John include:

  • Importance of hospitality and supporting missionaries
  • Dangers of loving preeminence and self-promotion in spiritual leadership
  • Integrity and walking in the truth
  • Imitating good behavior

Despite being less than 300 words, 3 John offers instructive examples for living the Christian life even today. By commending Gaius and condemning selfish ambition in church leaders like Diotrephes, the elder promotes crucially important values for followers of Jesus.

Key Takeaways from 3 John

3 John is the shortest book in the Bible, with only 15 verses. Despite its brevity, it contains some important lessons for Christians. Here are some key takeaways from 3 John:

Live in Truth

John commends Gaius for walking in the truth (v. 3-4). As Christians, we are called to live according to God’s truth, not according to the standards of the world. This means obeying God’s commandments and living righteously.

Extend Hospitality

Gaius is also commended for extending hospitality to fellow believers, even those he did not know personally (v. 5-8). We should be eager to show hospitality and generosity to brothers and sisters in Christ.

Imitate Good, Not Evil

John condemns Diotrephes, who loves to have preeminence and refuses to welcome other believers (v. 9-10). As Christians, we should imitate good examples like Gaius, not bad examples like Diotrephes. We must avoid pride and self-importance.

Do Good for the Sake of the Gospel

John urges Gaius to continue doing good works for fellow believers so that they can go out for the sake of the Name, i.e. to spread the Gospel (v. 6-8). We should support gospel ministry not for our own recognition, but for the sake of seeing Christ glorified.

Exercise Discernment

John Differentiates between Demetrius, who has a good testimony from everyone, and Diotrephes, who loves to be first (v. 12). We need spiritual discernment to distinguish between true and false teachers.

Despite being the shortest book, 3 John offers much wisdom for following Jesus. Some key lessons include: living in truth, showing hospitality, imitating good examples, supporting gospel ministry, and exercising discernment.

By putting these principles into practice, we can walk faithfully with Christ.


In summary, 3 John is the shortest book in the entire Bible with only 219 Greek words. Despite its brevity, it contains valuable lessons on living faithfully, handling conflict within the church, and the importance of truth and love.

Studying 3 John rewards us with practical wisdom for applying God’s principles in our relationships and ministry. Its powerful message reminds us that size does not determine significance when it comes to the Word of God.
