DANGEROUS REEFS IN THE CHURCH

Question:

What does the Bible mean when it says, “These people are dangerous reefs”? What are these reefs, and why are they considered a threat?

Answer:

Let’s examine Jude 1:12–13:

“These people are blemishes at your love feasts, eating with you without the slightest qualm—shepherds who feed only themselves. They are clouds without rain, blown along by the wind; autumn trees, without fruit and uprooted—twice dead. They are wild waves of the sea, foaming up their shame; wandering stars, for whom blackest darkness has been reserved forever.”
(Jude 1:12–13, NIV)

The apostle Jude, the brother of James and a servant of Jesus Christ, wrote this letter to warn believers about the infiltration of ungodly people into the Church—individuals who distort the grace of God and deny the Lord Jesus (Jude 1:4). In verses 12–13, Jude uses strong metaphors to describe the nature and danger of these individuals. One of the most striking images he uses is that they are “dangerous reefs at your love feasts.”

These kinds of reefs are especially dangerous because they are invisible to the eye but deadly to any vessel that sails too close. Likewise, these people are spiritually harmful: they appear to be part of the community, they participate in worship, and they fellowship without fear, yet their presence threatens to shipwreck the faith of others (1 Timothy 1:19).

False Teachers in Disguise

Just as hidden reefs can tear apart ships, false teachers and self-serving leaders can destroy the spiritual lives of those around them. These people care only for themselves—“shepherds who feed only themselves” (v. 12). Instead of guiding and protecting the flock, they exploit it (see also Ezekiel 34:2–4).

This warning is echoed throughout the New Testament:

Matthew 7:15 (NIV): “Watch out for false prophets. They come to you in sheep’s clothing, but inwardly they are ferocious wolves.”

2 Peter 2:1 (NIV): “There will be false teachers among you. They will secretly introduce destructive heresies…

”Acts 20:29–30 (NIV): “I know that after I leave, savage wolves will come in among you and will not spare the flock. Even from your own number men will arise and distort the truth…”

Even Judas Iscariot, one of the twelve disciples, serves as a prime example. He appeared to be one of Jesus’ closest followers but harbored betrayal in his heart. At the Last Supper, no one suspected him—only Jesus knew his true identity (John 13:21–27).

What Should We Learn from This?

This is a wake-up call to the Church. These “dangerous reefs” exist today—people who outwardly serve in ministry, preach in Jesus’ name, and lead churches but do not truly follow Christ. Some are motivated by greed, power, or even demonic influence.

Their impact is devastating. They:

Lead believers astray
Cause division and confusion
Promote sin under the guise of grace
Weaken the Church’s witness to the world

How Do We Guard Ourselves?

The only way to avoid spiritual disaster is to be rooted in the Word of God and walk in discernment through the Holy Spirit. Knowledge of Scripture equips us to recognize truth from error.
