Short answer: Matthew 5:21–22 does not mention calling someone the devil by name, so the passage gives no direct yes or no on that exact phrase. What Jesus does is place contemptuous speech toward a brother under the same warning of judgment as murder, because both flow from a heart that devalues a person made in God's image. Calling someone the devil is not the specific word Jesus names, but it carries the same dismissive weight as the insults he does name. The passage calls for examining your own speech first, not for using it as a weapon against others.
Where Jesus stands in the sermon on the mount
Matthew places these verses in the Sermon on the Mount, Jesus' extended teaching to his disciples in Galilee. The form is a series of contrasts: Jesus cites what his hearers had heard, then sets his own word beside it. Before he reaches murder, he has already raised the stakes. He has said that breaking even the least commandment and teaching others to do so makes a person least in the kingdom, and that the disciples' righteousness must exceed that of the scribes and Pharisees (5:19–20). That comparison is not a summons to tighter external rules. It is a call to the righteousness of the heart the law always intended.
The immediate shape of 5:21–22 is a three-step progression. Jesus begins with the command against murder and the judgment attached to it, then moves to anger, then to the insult Raca, then to the words You fool, each step raising the danger from judgment to the council to the fire of Gehenna. The escalation is the point. Anger nursed in the heart is the root, and insult is that anger given a voice. Jesus is not discarding the sixth commandment. He is filling out its meaning for a people already redeemed and already commanded not to murder.
The verses that follow keep this practical. Jesus imagines a worshipper at the altar who remembers that his brother has something against him, and tells him to leave the gift and be reconciled first (5:23–24). The setting matters: first-century Galilee under Roman rule, where public insult and shame carried real social weight. So this passage calls for self-examination before it is turned on anyone else. It does not silence legitimate warnings about false teaching, and it must never be used to pressure someone into unsafe reconciliation.
The passage sits inside Israel's covenant life, where the command against murder was given to a redeemed people, and Jesus speaks as one with authority over that command rather than against it. His hearers had received a tradition that paired the prohibition with a warning about judgment. Jesus accepts the prohibition and presses behind the act to the anger that precedes it. The contrast is not between the Old Testament and something new, but between a righteousness measured by outward acts and one that reaches the heart. That is the standard he holds up for his disciples, and it is the standard that exposes every hearer's need for grace.
What Jesus actually said about angry words
Jesus begins by quoting what his hearers had received: the command against murder and the warning that a killer stands liable to judgment. He does not cancel that. He presses behind it. Anger nursed against a brother, he says, already puts a person in danger of judgment. Then he names two insults, the term rendered Raca and the words You fool, each carrying escalating danger, up to the fire of Gehenna. Notice that these are not courtroom categories. They are ordinary words people throw at each other. Jesus is tracing the direction of the heart that each word reveals.
The terms matter. Raca was a slur, a way of saying someone is worthless or empty-headed. Calling a person a fool goes further, dismissing their judgment and character. Jesus does not grade sins by vocabulary alone; he shows that contempt spoken aloud is contempt held inside. So the question is not only whether a particular word is forbidden, but what we are doing to a person made in God's image when we say it. The warning about Gehenna is sober: it points to final judgment, not merely hurt feelings or earthly trouble. Jesus takes our speech that seriously.
That means this passage should first search our own mouths. Before we apply it to anyone else, we do well to ask what our words reveal about our hearts toward brothers and sisters. But it does not require silence when false teaching threatens the flock, and it does not demand that someone return to an unsafe situation to make peace. Jesus is exposing contempt, not honest warning or wise boundaries. Where we have spoken with contempt, the gospel calls us to confess it, seek forgiveness, and let grace reshape how we speak.
Anger, insult, and the heart behind the words
Jesus begins with the command his hearers already knew: murder brings judgment. Then he moves the command inward. Anger with a brother already puts a person in danger of judgment; a contemptuous label like Raca brings the council; calling someone a fool brings the fire of Gehenna (5:21–22). The progression is deliberate. Jesus is not adding three new crimes to a list. He is tracing murder back to the anger and contempt that precede it, and showing that God sees the root, not only the act. The specific phrase you are the devil is not what Jesus names here, but it belongs to the same family of speech: it treats a person as demonic rather than as a neighbor.
The stakes were set just before. Jesus had said that whoever breaks even the least of these commandments and teaches others to do so will be called least in the kingdom, and that the disciples' righteousness must exceed that of the scribes and Pharisees (5:19–20). That comparison is easy to misread as a call to stricter externals. Jesus means the opposite: a righteousness of the heart that the law always intended. He is not abolishing the command against murder. He is filling out its meaning for a covenant people who were redeemed before they were commanded, and who were never meant to nurse contempt in secret.
The verses that follow turn the warning into practice. If you are at the altar with your gift and remember that your brother has something against you, leave the gift and go; be reconciled first, then come and offer (5:23–24). Worship and reconciliation are bound together. So examine your own speech before you apply this to anyone else. This passage does not silence legitimate warnings about false teaching, and it must never be used to pressure someone into unsafe reconciliation. What it does is expose the anger and contempt God sees, and call us to deal with our own hearts first.
Where readers disagree about anger and insult
Careful readers part ways on how these warnings land on the church. Some hear Jesus pressing the seriousness of sin on his disciples, arguing that genuine faith reshapes speech, so contempt toward a brother is a matter for repentance, not a small failing. Others read the language of judgment as covenant warning aimed at a nation, and they apply it to individuals more loosely. The disagreement is real, but both readings keep the same center: Jesus raises the stakes, tracing murder back to the anger that precedes it, and refuses to treat insult as trivial. Neither reading makes contempt safe.
The phrase "without cause" in Matthew 5:22 divides readers too. Some take it as a guard against every flash of anger, since Jesus names the danger so plainly. Others see a distinction between the anger that flares against genuine wrong and the settled contempt that dismisses a person made in God's image. Readers also debate whether "Raca" and "fool" are two specific insults or samples of a whole category of demeaning speech. The text sets its own limits: it addresses a brother, not enemies or false teachers, so it cannot be turned into a ban on warning about error, and it never licenses name-calling in return.
What stays central across these disagreements is that contemptuous speech toward a brother is serious before God, and that reconciliation is not optional. Jesus pictures a worshiper at the altar who remembers a grievance and tells him to leave the gift and go first. That is a searching word, and the honest place to start is your own mouth, not someone else's. Yet the command to be reconciled does not require returning to harm; wisdom still matters where safety is at stake. The passage calls each disciple to examine their own speech and to seek peace without pretending the wound was never there.
The king who bore the judgment he warned about
Jesus does not set aside the sixth commandment; he presses it down into the heart. In 5:21–22 he moves from the act of murder to the anger that precedes it and to the words that carry contempt. The progression is deliberate: anger without cause faces judgment, a slur like "Raca" faces the council, and "You fool!" faces the fire of Gehenna. The point is not that three insults receive three penalties, but that God weighs speech. Calling a brother worthless is not harmless venting. Jesus treats it as a matter of life and death, which means the question about calling someone the devil begins with our own mouths, not with someone else's.
Yet the Sermon does not leave us under a ladder of escalating threats. The same Jesus who raises the standard is the one who keeps it. He was insulted and accused, and he did not answer in kind. More than that, he took the judgment this passage warns about, so that people who have spoken contemptuously can be forgiven and changed rather than merely condemned. The righteousness that exceeds that of the scribes and Pharisees in 5:20 is not a bar we clear by trying harder; it is the King's own righteousness given to his people. Grace comes first, and our guarded speech is the response.
That shapes how this text is used. It searches my own tongue before it is aimed at anyone else. It also does not require silence about false teaching; warning against error is not the same as despising a person. And it must never be used to push someone back into harm under the label of reconciliation. Reconciliation with a brother is possible because we were first reconciled to God in Christ. Where it is safe and honest, we go and make peace; where it is not, we still refuse contempt and leave the judgment with God.
Examining your own speech before you bring your gift
Jesus takes the sixth commandment and presses it inward. Anger nursed against a brother, the insulting word, the dismissive label all fall under the same judgment he describes in 5:21–22. Before you apply this to anyone else, turn it on your own mouth. Ask honestly whether you have used demonic language to describe a fellow believer over a disagreement, and whether irritation has hardened into settled contempt. The text does not ask whether your anger felt justified. It asks what your speech has done to a person made in God's image. That is where examination begins, and it is uncomfortable precisely because it is specific.
Then notice where Jesus sends you. In 5:23–24 the worshiper at the altar remembers that his brother has something against him, and he leaves the gift and goes. Reconciliation comes before religious activity. That means concrete steps: naming what you said, apologizing without qualifiers, and where possible restoring the relationship. This passage does not require you to pretend false teaching is harmless, and it should never be used to pressure someone back into an unsafe situation. Jesus named error plainly. Calling out false doctrine is not the same as damning a person, and the difference is worth guarding in your speech.
Let grace be the ground you stand on here. You are not cleaning up your words to earn a place in the kingdom; you are responding to a Savior who bore the judgment you deserved. That frees you to confess quickly and to leave results with God, because 5:23–24 promises a direction to walk, not a guaranteed outcome. Pursue peace, speak truth without contempt, and trust the Lord with the person across from you. The call is faithful obedience, not a formula that guarantees the response you hope for.
Biblical fidelity check
Matthew 5:21–22 was read by tracing its structure first. Jesus quotes two received statements about murder and judgment, then sets his own authority beside them, naming anger, the insult rendered Raca, and the words You fool, each with escalating danger. The interpretive risks are specific: treating without cause as a loophole, treating the insults as a fixed list rather than examples of contempt, and turning Gehenna into a threat about earthly loss. The text addresses a brother, not enemies or false teachers, and it never authorizes name-calling.
The real disagreement is how directly these warnings bind the church. Some readers hear them as covenant warnings to a nation and apply them less directly to individuals; others hear them as showing that genuine faith changes speech. Readers also differ over whether without cause guards against all anger or distinguishes righteous from sinful anger, and whether the insults are specific or representative. What stays central is that contemptuous speech toward a brother is serious before God and reconciliation is not optional for the disciple.
Other passages that speak to Matthew 5:21-22
These themes run through the rest of the Sermon on the Mount and into the apostles' teaching on the tongue. For further study, see Matthew 1: Genealogy and Birth of Jesus on anger and reconciliation in the church, Matthew 10: Jesus Sends the Twelve with Authority on speech that builds rather than tears down, Matthew 12: Lord of the Sabbath and Sign of Jonah on judging others rightly, and Matthew 13: Parables of the Kingdom on guarding the heart as the source of words and actions.
Frequently asked questions
Is it a sin to call someone the devil?
Matthew 5:21–22 does not name that exact phrase, so it does not settle the question by direct command. What it does is warn that contemptuous speech toward a brother puts a person in danger of judgment, because Jesus treats such words as the visible edge of the same root that ends in murder. Calling someone the devil treats a person as wholly demonic and worthless rather than as a neighbor made in God's image, which belongs to that same family of contempt. The passage turns the question inward: examine your own anger and your own tongue before you use this text to judge anyone else. It also does not license you to ignore real false teaching or to force unsafe reconciliation, so the warning is about the disposition behind the words, not a ban on all discernment.
Does Matthew 5:22 forbid all anger, or only anger without cause?
The verse as supplied reads that everyone who is angry with his brother without a cause will be in danger of the judgment. That wording limits the warning to anger that has no cause, which means the passage is not a blanket ban on every flash of anger. But Jesus is not handing out permission to nurse resentment; he is showing that anger is a moral matter God sees, not just an inner feeling that never counts. Some readers hear in the phrase a caution against self-justifying anger, since we are quick to call our own anger reasonable and everyone else's unwarranted. What stays central is that anger belongs under God's judgment and must be dealt with, not excused.
What did Jesus mean by “Raca” and “You fool”?
Both are insults, and Jesus escalates the warning as the insult grows more dismissive. The first term is a contemptuous put-down, the kind of word that says a person is worthless, and Jesus says it puts a person in danger of the council. The second, calling someone a fool, he places in danger of the fire of Gehenna, the strongest warning in the passage. Jesus is not grading vocabulary for its own sake; he is showing that words which write a person off carry real weight before God. The point is the contempt behind the words, not a list of forbidden syllables.
