Matthew 18:6
What does Matthew 18:6 mean?
but whoever causes one of these little ones who believe in me to stumble, it would be better for him that a huge millstone should be hung around his neck, and that he should be sunk in the depths of the sea.
The short answer
Matthew 18:6 is one of the most severe things Jesus ever said. He tells his followers that if anyone causes "one of these little ones" who believe in him to stumble, it would be better for that person to have a huge millstone hung around his neck and be sunk "in the depths of the sea." A millstone was an enormous grinding stone, heavy enough that it took an animal to turn it. Jesus is saying that a swift, certain drowning would be a kinder fate than what awaits someone who trips up a vulnerable believer.
The word behind "stumble" is the Greek skandalon. As Greg Garrett points out, the word literally names a trap or snare set in someone's path—something you step into without seeing it. In this verse it means anything that causes another person to sin. So the picture is not of an accident but of an obstacle placed where a trusting person will fall over it. The "little ones" here are those with a simple, childlike faith—people who follow without suspicion and are easiest to mislead.
Why such shocking severity? Jerome Creach reads this as Jesus pointing to the stern side of God: divine anger stirred on behalf of the innocent and helpless. God takes personally what is done to the defenseless. Creach also notes that Christians throughout history have appealed to passages like this one to justify coercive action—even war—in defense of those who cannot defend themselves, and he presses the hard question of whether that use really fits Jesus' teaching.
Either way, the force of the verse lands close to home. Before it authorizes anyone to punish the guilty, it asks each reader to examine what traps they themselves may be laying. The millstone image is meant to make us take that question with deadly seriousness.
What scholars say
Creach hears in this verse the stern side of God roused against those who harm the helpless—and asks whether the church's appeal to such passages to justify protective force truly fits Jesus' teaching. Garrett grounds the warning in its communal setting, unpacking skandalon as a trap laid in someone's path and showing how Matthew 18 gives practical instruction for a fellowship learning to protect its simplest believers.
“The New Testament, as well as the Old Testament, speaks of the wrath of God, and Jesus refers to this stern side of God in response to those who would harm the innocent and helpless: “If any of you put a stumbling block before one of these little ones who believe in me, it would be better for you if a great millstone were fastened around your neck and you were drowned in the depth of the sea” (Matt. 18:6). Accenting passages like this, many in the church have developed a theology that includes legitimate uses of war and other coercive action in order to protect those who cannot protect themselves (see Simpson, War, Peace, and God , 80–81). Thus human action in war may be understood as just under certain circumstances, and “just war” is understood as human participation in God’s corrective and punitive work (see further the discussion of Ps. 82 below). But does this idea really fit within the teachings of Jesus?”
“That’s why it’s fortunate that in Matthew 18 Jesus reveals himself to be a down-to-earth leader as well as a lofty spiritual guide. Here we find Jesus giving practical instruction into how the new fellowship might function. He begs his followers not to be stumbling blocks to others in the community, especially those who are like children in their simple faith (the Greek skandalon in this passage means, literally, a trap or snare that people might step in, although here it refers specifically to something that causes others to sin). He tells them how to deal with hurts that threaten the community: Go and try to resolve the conflict one on one, gently, if possible. If not, then muster the resources of the community behind you.”
What it means for you
The practical question this verse raises is uncomfortable: whose faith am I tripping? A skandalon is rarely dramatic. It can be cynicism dressed up as sophistication, hypocrisy a newer believer notices before you do, or influence used carelessly over someone who trusts you—a child, a student, a friend just beginning to believe.
Jesus' severity here is also a comfort to the vulnerable: God is fiercely on the side of the little ones. But notice where the warning points. It does not first hand us a weapon against those who harm others; it first hands us a mirror. Take stock of what you leave in other people's paths.
Matthew 18 in context
Matthew 18 opens with the disciples asking who is greatest in the kingdom of heaven. Jesus answers by placing a child in front of them: greatness means becoming humble like a little one, and welcoming such people is welcoming him. Verse 6 is the dark counterpart to that welcome—the warning against harming those same little ones. The rest of the chapter stays practical: Jesus teaches how to confront a fellow believer who sins, how the community should handle unresolved conflict, and how far forgiveness must extend, ending with the parable of the unforgiving servant.
