What is Jude about?

Jude is a 25-verse letter that urges believers to contend for the faith handed down once for all to the saints (Jude 1:3). Ungodly people had slipped into the churches, turning God's grace into license for immorality and denying Jesus Christ as Master and Lord (1:4). Jude recalls how God judged unbelieving Israel, rebellious angels and Sodom (1:5-7), portrays the intruders with vivid images (1:8-16) and calls the faithful to build themselves up, pray, keep themselves in God's love and show mercy (1:20-23), ending with praise to the God who is able to keep them from stumbling (1:24-25).

Author: Jude, a servant of Jesus Christ and brother of James (Jude 1:1). Early tradition identifies him as Judas, one of the brothers of Jesus (Matthew 13:55; Mark 6:3), not Judas Iscariot.
Date: Uncertain: many date it between AD 60 and 80; proposals range from the 50s to about AD 100.
First readers: Unnamed believers, called, loved by God and kept for Jesus Christ (1:1), probably mostly Jewish Christians steeped in Scripture, whose congregations immoral intruders had entered (1:4).
Genre: Letter (general epistle)
Chapters: 1 chapter
Key verse: Jude 1:3

Historical context

Jude was written in the second half of the first century, when the gospel had spread from Jerusalem across the Roman world and churches depended on traveling teachers and prophets who received hospitality from one congregation to the next. That openness could be abused. Jude says that certain people had crept in unnoticed (1:4). They ate at the church's love feasts (1:12), appealed to their dreams as authority (1:8), rejected authority and caused divisions (1:19). Their error was more moral than speculative: they treated grace as permission to sin.

The author identifies himself through his brother James, the leader of the Jerusalem church, whom the Jewish historian Josephus says was stoned around AD 62. The brothers of Jesus had not believed in him during his ministry (John 7:5), but after the resurrection they were praying with the disciples (Acts 1:14), and Paul mentions that the brothers of the Lord traveled in ministry with their wives (1 Corinthians 9:5). Jude's easy use of Jewish writings such as 1 Enoch suggests a Jewish-Christian setting. The second-century writer Hegesippus, quoted by the historian Eusebius, reports that grandsons of Jude, poor farmers with work-hardened hands, were brought before the emperor Domitian and released as harmless.

Geographical context

The letter names neither the place where it was written nor the city of its readers. Its Jewish-Christian flavor leads many scholars to think of Palestine or Syria, while its early use by teachers in Alexandria and its close link with 2 Peter have led others to suggest Egypt or Asia Minor.

The places Jude does mention come from Israel's story: Egypt, from which the Lord saved his people before judging the unbelieving in the wilderness (1:5); Sodom, Gomorrah and the surrounding cities near the Dead Sea, whose ruin became a lasting warning (1:7); and the unmarked grave of Moses in Moab, behind the dispute between Michael and the devil (1:9; Deuteronomy 34:5-6). His images come from the eastern Mediterranean landscape: clouds that pass without rain, trees without fruit at the end of the season, the restless sea and the stars by which travelers steered (1:12-13).

Why does the book of Jude exist?

Jude had intended to write about the salvation he shared with his readers, but news of the intruders made him change his plan and send an urgent appeal instead (1:3). His readers were in danger of tolerating people who looked like members of the community, shared its fellowship meals and spoke with confidence, yet lived immorally, despised authority and divided the church. Jude wanted them to see these people clearly in the light of Scripture: the same pattern of unbelief, rebellion and greed that God had judged in the past and that the apostles had predicted for the last time (1:17-18).

The letter is not only a warning. Its second half turns to the faithful with practical commands for remaining in God's love (1:20-21) and a call to rescue those who are wavering, combining mercy with holy caution (1:22-23). For the whole church, Jude provides a classic call to guard the apostolic faith, a sober reminder that grace never permits sin, and a closing doxology that rests all perseverance on the power of God (1:24-25).

Outline of Jude

Jude 1:1-2
Greeting to the called and kept
Jude, servant of Jesus Christ and brother of James, writes to those called by God, loved in God the Father and kept for Jesus Christ, praying that mercy, peace and love will be multiplied to them.
Jude 1:3-4
Contend for the faith
Jude sets aside his plan to write about their common salvation and urges his readers to contend for the faith delivered once for all, because ungodly people have slipped in, turning grace into sensuality and denying Jesus Christ.
Jude 1:5-7
Three warnings from the past
The Lord who saved Israel from Egypt destroyed those who did not believe; angels who abandoned their proper place are kept in darkness for judgment; and Sodom and Gomorrah stand as an example of the punishment of eternal fire.
Jude 1:8-13
Portrait of the intruders
Relying on dreams, they defile the flesh and slander what they do not understand, unlike the archangel Michael. They follow Cain, Balaam and Korah, and Jude pictures them as hidden reefs, waterless clouds, dead trees, wild waves and wandering stars.
Jude 1:14-19
Foretold by Enoch and the apostles
Enoch, the seventh from Adam, foretold that the Lord would come with his holy ones to judge the ungodly. These grumblers and boasters fulfill that word and the apostles' warning that scoffers would come in the last time, causing divisions.
Jude 1:20-23
Keep yourselves in God's love
The faithful are to build themselves up in their most holy faith, pray in the Holy Spirit, keep themselves in God's love and wait for Christ's mercy, while showing mercy to doubters and snatching others from the fire.
Jude 1:24-25
Glory to the God who keeps
Jude closes with praise to the only God our Savior, who is able to keep believers from stumbling and present them blameless and joyful before his glory, through Jesus Christ our Lord, now and forever.

Famous passages in Jude

Jude 1:3
Contend for the faith
Jude's central appeal: believers must struggle earnestly for the faith that God entrusted once for all to his holy people. The verse treats the gospel as a body of truth handed down by the apostles, not a message to be revised, and it is often quoted when the church must defend sound teaching.

Jude 1:9
Michael and the body of Moses
The archangel Michael, disputing with the devil over the body of Moses, did not dare to pronounce a slanderous judgment but left it to God, saying that the Lord would rebuke him. Jude contrasts this restraint with the arrogance of the intruders. The episode is not told in the Old Testament, and early writers traced it to a Jewish work about Moses.

Jude 1:11
The way of Cain, Balaam and Korah
In one verse Jude compares the intruders to three Old Testament figures: Cain, who murdered his brother; Balaam, who was drawn by reward and later advised the seduction of Israel (Numbers 31:16); and Korah, who rebelled against the leaders God had appointed. Together they portray envy, greed and rebellion against God's authority.

Jude 1:14-15
The prophecy of Enoch
Jude cites a prophecy of Enoch, the seventh from Adam: the Lord comes with countless holy ones to judge everyone and to convict the ungodly of their deeds and harsh words. The words closely match the Jewish book known as 1 Enoch (1:9), and this quotation is one of the most discussed features of the letter.

Jude 1:20-21
Keep yourselves in the love of God
Jude gives the faithful their plan: build yourselves up in your most holy faith, pray in the Holy Spirit, keep yourselves in God's love and wait for the mercy of Jesus Christ that leads to eternal life. Father, Son and Spirit all appear in these two verses, a pattern for steady Christian growth.

Jude 1:22-23
Mercy and rescue
Believers must not only resist error but help those caught by it: show mercy to those who doubt, snatch others out of the fire and show mercy with fear to still others, hating even the garment stained by the flesh. The images of fire and of a soiled garment recall Zechariah 3:2-4.

Jude 1:24-25
The great doxology
Jude ends by praising the God who is able to keep believers from stumbling and to present them blameless before his glory with great joy. Glory, majesty, dominion and authority belong to him through Jesus Christ, before all time, now and forever. It is one of the best-known benedictions in Christian worship.

Main themes

Contending for the faith: The faith is a body of truth delivered once for all to the saints (1:3). Guarding it is not optional: believers must recognize teaching and living that contradict the apostles' message and refuse to let them reshape the church, yet they do so with humility, as Michael did (1:9, 17).
Grace is not a license to sin: The intruders turned the grace of God into sensuality (1:4). Jude insists that true grace leads to holiness, and that sexual immorality, greed and contempt for authority amount to a denial of Jesus Christ as Master and Lord, whatever a person claims.
The certainty of God's judgment: Unbelieving Israel, the angels who left their place, Sodom and Gomorrah, Cain, Balaam and Korah show that God does not overlook ungodliness (1:5-11). Enoch's prophecy and the apostles' warnings confirm that the Lord will come to judge (1:14-18).
Kept by God, keeping ourselves: Jude begins with believers kept for Jesus Christ (1:1) and ends with the God who is able to keep them from stumbling (1:24). In between he commands them to keep themselves in God's love (1:21): God's preserving power and human responsibility go together.
Mercy toward the wavering: Contending for the faith is not harshness. Jude calls believers to show mercy to doubters, to rescue those in danger and to show mercy even to the deeply compromised, with fear and hatred for sin but with compassion for the sinner (1:22-23).
Remembering Scripture: Jude twice tells his readers to remember (1:5, 17). He reads the Old Testament as a mirror for the present, applying its stories of unbelief and rebellion to the threats facing the church, and he holds up the words of the apostles as the standard.

Main characters

Jude: The author, a servant of Jesus Christ and brother of James, traditionally one of the brothers of Jesus who came to faith after the resurrection. He writes with pastoral urgency, warm toward his beloved readers and severe toward those who endanger them (1:1, 3, 17, 20).
The beloved readers: Believers called by God, loved in God the Father and kept for Jesus Christ (1:1). Jude addresses them as beloved again and again (1:3, 17, 20) and trusts them to stand firm and to help those who are wavering.
The intruders: Ungodly people who slipped into the churches unnoticed, shared in the love feasts and spread an immoral version of grace. Jude calls them grumblers, boasters and people who cause divisions, worldly and devoid of the Spirit (1:4, 12, 16, 19).
Michael the archangel: The angel leader who also appears in Daniel and Revelation. In Jude he disputes with the devil over the body of Moses yet refuses to pronounce judgment himself, leaving it to the Lord, a model of humility before God's authority (1:9).
Enoch: The seventh generation from Adam, who walked with God and was taken by him (Genesis 5:21-24). Jude cites a prophecy attributed to him about the Lord coming with his holy ones to judge the ungodly (1:14-15).
Cain, Balaam and Korah: Three Old Testament examples of the intruders' sin: Cain killed his brother (Genesis 4:8), Balaam was drawn by reward and led Israel astray (Numbers 22-24; 31:16), and Korah rebelled against Moses and Aaron and perished (Numbers 16).

In-depth study of Jude

Introduction

Jude is easy to overlook. It sits just before Revelation, it has only 25 verses, and it is full of references to angels, Enoch and the body of Moses that puzzle modern readers. Yet it contains one of the clearest calls in the Bible to guard the gospel (1:3) and one of its most glorious doxologies (1:24-25).

Its message is urgent: a church can be harmed from within by people who use the language of grace while living as if God had no claim on them. Jude writes like a preacher. He piles up vivid images, draws on Israel's history and moves from warning to encouragement, so that the believers he calls beloved will stand firm and help others to stand.

Who wrote Jude and when?

The brother of James

The author introduces himself as Jude, servant of Jesus Christ and brother of James (1:1). The only James well known enough to need no further description was James the brother of the Lord, the leader of the Jerusalem church (Acts 15:13; Galatians 1:19). That makes Jude another of the brothers of Jesus listed in Matthew 13:55 and Mark 6:3. Like James (James 1:1), he does not mention the family tie but calls himself a servant, a striking sign of humility in someone who grew up in the same home as Jesus.

Not one of the Twelve

Some early writers identified the author with the apostle Judas son of James (Luke 6:16). Most interpreters think otherwise, because Jude speaks of the apostles as a group whose predictions his readers should remember (1:17), not as one of them.

Dating the letter

The letter gives few clues. Its warnings fit the decades when the apostolic generation was passing, and many date it between AD 60 and 80. Those who think a later author wrote in Jude's name place it near the end of the first century. Defenders of Jude's authorship point out that an imitator seeking authority would more likely have called himself the brother of the Lord.

Literary style and structure

A sermon in letter form

Jude has the greeting and closing of a letter, but its body reads like a short sermon. Its Greek is vigorous and colorful, with several words found nowhere else in the New Testament, and its images tumble one after another: hidden reefs, waterless clouds, uprooted trees, wild waves and wandering stars (1:12-13).

Example and application

In the central section (1:5-19) Jude follows a pattern known from Jewish interpretation of Scripture. He presents an example or a text and then applies it with the word these (1:8, 10, 12, 16, 19). Each time the past interprets the present danger.

Groups of three and the word keep

Jude loves triplets: called, beloved and kept (1:1); mercy, peace and love (1:2); Israel, the angels and Sodom (1:5-7); Cain, Balaam and Korah (1:11). The idea of keeping runs through the letter: believers are kept for Jesus Christ (1:1), the angels who did not keep their position are kept in chains (1:6), darkness is kept for the intruders (1:13), believers must keep themselves in God's love (1:21), and God is able to keep them from stumbling (1:24).

The flow of the letter

Greeting (1:1-2).
Purpose: contend for the faith (1:3-4).
Examples from the past and their application (1:5-16).
The apostles' warning (1:17-19).
Exhortation to the faithful (1:20-23).
Doxology (1:24-25).

Jude in the story of the Bible

Jude reads the Old Testament as a series of warning signs. The generation that left Egypt but died in the wilderness because of unbelief (Numbers 14:26-35), the angels who abandoned their place, often linked with Genesis 6:1-4, and the fire that fell on Sodom and Gomorrah (Genesis 19:24-25) show that privilege does not protect anyone who rebels against God. Cain (Genesis 4:3-8), Balaam (Numbers 22-24; 31:16) and Korah (Numbers 16:1-35) illustrate envy, greed and rebellion.

Smaller echoes are everywhere. Michael's words to the devil repeat the rebuke of Satan in Zechariah 3:2, and the fire and stained garment of Jude 1:23 come from the same scene, where Joshua the high priest is a brand plucked from the fire and is stripped of filthy clothes (Zechariah 3:2-4). Shepherds who feed only themselves recall Ezekiel 34:2, and the sea that casts up its shame recalls Isaiah 57:20.

In the New Testament, Jude stands beside Jesus' warning about false prophets in sheep's clothing (Matthew 7:15) and Paul's warning that fierce wolves would come in among the flock (Acts 20:29-30). Its closest relative is 2 Peter 2, and Revelation, which follows Jude in our Bibles, again denounces the teaching of Balaam (Revelation 2:14).

Jude and Jesus Christ

Master and Lord. The intruders deny Jesus Christ, the only Master and Lord (1:4); the King James Version, following later manuscripts, names both God and our Lord Jesus Christ here. The word for Master is used elsewhere of God himself, and Jude shows that denying Christ can happen through a way of life, not only through words.
Kept for him. Believers are kept for Jesus Christ (1:1) and wait for his mercy, which leads to eternal life (1:21). Their future rests on his coming.
The Lord who comes. Enoch's prophecy of the Lord coming with his holy ones (1:14) matches the New Testament hope of Christ's return with all his saints (1 Thessalonians 3:13).
Through Jesus Christ. Glory is given to the only God our Savior through Jesus Christ our Lord (1:25).
Jesus in the exodus? Several important ancient manuscripts of 1:5 say that Jesus saved a people out of Egypt, and some modern translations follow them. That reading would present Christ as active in Israel's history, as Paul does when he says that the rock in the wilderness was Christ (1 Corinthians 10:4).

There is also a quiet testimony in the first verse. If the author is the brother of Jesus, the man who once shared his home now calls him Master and himself his servant.

Interpretive challenges

Can a Bible book quote 1 Enoch?

Jude cites a prophecy found in 1 Enoch, a Jewish work that is not part of the Old Testament. Quoting a source does not endorse all of it; Paul quotes pagan poets (Acts 17:28; Titus 1:12). Some think Jude regarded this particular saying as a genuine prophecy preserved by tradition; others think he used a text his readers valued to make a point that Scripture itself teaches. Either way, the inspired letter affirms that the saying is true.

Who were the angels who left their dwelling?

Many in ancient Judaism and the early church read 1:6 in the light of Genesis 6:1-4, where the sons of God took human wives, and Jude's comparison with Sodom, which went after unnatural desire in the same way (1:7), supports that reading for many interpreters. Others see a reference to the original fall of angels who joined Satan's rebellion. Both readings agree on the point: rebellion against the order God established ends in judgment.

Who were the intruders?

Jude does not name them or describe their doctrine. Some have seen an early form of Gnosticism, but many scholars today see traveling teachers who claimed spiritual insight through dreams (1:8), rejected moral restraint and authority, and used the community for profit (1:11, 16). Their basic error was practical: they denied the lordship of Christ by how they lived.

Why do translations differ in a few verses?

Some differences come from the meaning of words, others from the manuscripts. The word used for the intruders at the love feasts (1:12) can mean hidden reefs or stains, so versions say reefs, spots or blemishes. In 1:22-23 some manuscripts describe three groups (doubters, those to be snatched from the fire and those to be pitied with fear), others only two, and some tell readers to convince the first group rather than to have mercy on them. In 1:25 older versions such as the King James follow later manuscripts that praise the only wise God and lack the words through Jesus Christ our Lord and before all time. None of these differences changes the teaching of the letter: believers must reach out with mercy, adjusting their approach to each person's condition, and give all glory to God.

Little-known facts

Jude and Judas are the same name. In Greek the author's name is Ioudas, the same as Judas Iscariot and the patriarch Judah. English Bibles write Jude to keep them apart.
Michael's only title. Jude 1:9 is the only verse in the Bible that calls Michael an archangel; Daniel calls him a prince (Daniel 10:13; 12:1).
Enoch among the Dead Sea Scrolls. Aramaic fragments of 1 Enoch were found at Qumran, but the complete work survives only in an ancient Ethiopic translation.
Planets in the Bible. The Greek word for the wandering stars of 1:13 is the source of the English word planet.
A family remembered. Hegesippus, a second-century writer quoted by Eusebius, says that grandsons of Jude, accused of descending from David, were brought before the emperor Domitian, showed their calloused farmers' hands and were released.
A disputed but accepted book. Jerome reported that many rejected Jude because it quotes Enoch, and Eusebius listed it among the books some questioned, yet the major canon lists of the fourth century include it.

How to study Jude

Read it whole and trace its patterns

Jude can be read aloud in about five minutes. Read it several times, marking every these, every beloved and every form of the word keep. Notice the turn at 1:17 and 1:20, where Jude stops describing the intruders and speaks to the faithful.

Read it with its background

Before the study, read the stories Jude assumes: Genesis 4 and 19, Numbers 14, 16 and 22-24, Deuteronomy 34 and Zechariah 3. Then compare Jude with 2 Peter 2 and note what each writer emphasizes.

Questions to ask

What does Jude say about God's grace, and how was it being distorted?
How do the Old Testament examples shed light on the present danger?
What do the commands of 1:20-23 look like in daily life?
How can a church guard the truth without becoming harsh?

Teaching it in a class or small group

A four-week plan works well: called, kept and contending (1:1-4); lessons from history (1:5-16); how to stand firm and help others (1:17-23); and the doxology (1:24-25). Help the group avoid using Jude to label people and stress the mercy of 1:22-23. Close each session by reading the doxology aloud, and invite the group to memorize it by the last week.

Frequently asked questions about Jude

Who wrote the book of Jude?

The letter was written by Jude, who calls himself a servant of Jesus Christ and brother of James (Jude 1:1). Since the early church he has been identified as Judas, one of the brothers of Jesus named in Matthew 13:55 and Mark 6:3, and brother of James, the leader of the Jerusalem church. Instead of claiming kinship with the Lord, he calls himself his servant. Some scholars think a later writer used his name, but many accept his authorship.

When was Jude written?

The date is uncertain, because the letter mentions no datable events or places. Many scholars place it between AD 60 and 80; some argue for the 50s, and those who doubt that Jude wrote it date it toward AD 100. If 2 Peter drew on Jude, as most scholars think, Jude is the earlier letter, and tradition places Peter's death in the 60s.

What is the main message of Jude?

Believers must contend for the faith once for all delivered to the saints and refuse teachers who turn God's grace into an excuse for immorality and deny Jesus Christ (Jude 1:3-4). God judges such ungodliness, as Scripture shows, but he keeps his people. They are to build themselves up, pray, remain in God's love and show mercy, trusting the God who keeps them from stumbling (1:20-25).

How many chapters does Jude have and how is it organized?

Jude has a single chapter of 25 verses, so its verses are cited as Jude 1:3 or simply Jude 3. After the greeting (1:1-2) and the purpose (1:3-4), Jude gives examples of judgment (1:5-7), describes the intruders and the prophecies about them (1:8-19), exhorts the faithful (1:20-23) and closes with a doxology (1:24-25).

Is the Jude who wrote this letter Judas Iscariot?

No. Judas Iscariot betrayed Jesus and died before the church began its mission (Matthew 27:3-5). The New Testament also mentions an apostle called Judas son of James, or Judas not Iscariot (Luke 6:16; John 14:22). The author is usually identified as yet another Judas, the brother of Jesus and of James. English Bibles call him Jude to distinguish him from the betrayer, though the Greek name is the same.

Why does Jude quote the book of Enoch?

Jude 1:14-15 closely follows a passage now numbered 1 Enoch 1:9, from a Jewish writing composed in the centuries before Christ and well known in Jude's day. Quoting a book does not make all of it Scripture: Paul quotes Greek poets (Acts 17:28; Titus 1:12). Jude affirms that this particular saying is a true prophecy of the Lord's judgment, using words his readers already respected.

What was the dispute over the body of Moses?

Jude 1:9 says that the archangel Michael disputed with the devil about the body of Moses. The Old Testament says only that the Lord buried Moses in Moab and that no one knows where his grave is (Deuteronomy 34:5-6). Early Christian writers, Origen among them, linked the story to a Jewish book called the Assumption of Moses, whose ending is lost. Jude's point is Michael's humility: he left judgment to the Lord.

How are Jude and 2 Peter related?

Jude 1:4-18 closely parallels 2 Peter 2:1-3:3. Both describe false teachers, use the examples of the angels, Sodom and Balaam, and warn of scoffers in the last days. Most scholars think 2 Peter drew on Jude; others think Jude used 2 Peter or that both used a common source. 2 Peter leaves out the explicit references to Enoch and to the body of Moses and adds Noah and Lot.
