The Bible teaches that words are powerful. Cussing is one type of speech that some Christians wonder about because Scripture doesn’t directly mention modern swear words.
It is a sin to cuss, curse, and swear. Although the Bible doesn’t specifically mention modern swear words, saying them is a clear violation of Scripture’s commands against impure, unholy, and obscene speech. Most cuss words are sinful all the time. A few might not be considered sinful depending on their context.

Why is cussing wrong?
Cussing refers to using obscene words, which are often associated with parts of the human body (e.g. male and female genitals) and sexual intimacy (e.g. intercourse).
Cuss words — also called curse words or swear words — are slang terms often expressed in anger or for inappropriate humor. They don’t refer to the human body or sexual intimacy in a healthy and holy manner.
What does the Bible say about cussing? Scripture commands Christians to avoid obscene talk (e.g. Col. 3:8; see more verses below). Obscene talk is any type of speech that is offensive, disgusting, and dishonors God’s creation of the body and his design for sexual intimacy. The Greek word translated “obscene” in the ESV (aischrologia) refers to “filthy speech” and “foul language.”
|But now you must put them all away: anger, wrath, malice, slander, and obscene talk from your mouth.
|But now you must also rid yourselves of all such things as these: anger, rage, malice, slander, and filthy language from your lips.
|But now is the time to get rid of anger, rage, malicious behavior, slander, and dirty language.
|But now ye also put off all these; anger, wrath, malice, blasphemy, filthy communication out of your mouth.
|But now you yourselves are to put off all these: anger, wrath, malice, blasphemy, filthy language out of your mouth.
|But now you also, put them all aside: anger, wrath, malice, slander, and abusive speech from your mouth.
Why do cuss words often refer to the human body and sexual intimacy? Most cuss words are slang terms for subjects that people feel uncomfortable talking about. Some people feel embarrassed or awkward using the proper anatomical or biological terms for certain topics, so they use words that are juvenile and sophomoric.
Does the Bible forbid all talk about the body and sex? No. The Bible doesn’t prohibit healthy and holy conversations about the private parts of a human body or sexual intimacy.
Examples of healthy and holy speech include conversations with a medical doctor and parents teaching their children about the anatomy and biology of the human body.
Does context matter in determining what words are unholy? It can. Most cuss words are unhealthy and unholy all the time. A few may be considered appropriate in one context but not in another. For example, a word that most consider a cuss word today, may not have been so a century ago. The key is whether or not the speech is culturally obscene.

How can a person stop cussing?
What if some people are in the habit of cussing? While cuss words relieve tension, due to anger or discomfort, some people simply continue to speak them out of habit. To mindlessly say cuss words, without thinking about their unhealthy and unholy nature, violates the Bible’s clear instructions. How can a person break the habit of cussing?
First, a person should consider the principle of “garbage in, garbage out.” If a person constantly subjects themselves to cuss words through movies, social media, music, and perhaps certain relationships, they will be more likely to mimic the speech in their own lives.
Of course, not all relationships can be avoided (e.g. family), yet there is wisdom in eliminating or drastically reducing exposure to hearing cuss words in daily life if a person truly wants to break the habit.
- Proverbs 22:24-25, “Make no friendship with a man given to anger, nor go with a wrathful man, lest you learn his ways and entangle yourself in a snare.”
Second, a person should consider the principle of replacing bad thoughts with good thoughts. Rather than just trying hard to resist saying a cuss word when the temptation arises in a person’s thoughts, they can preemptively fill their thinking with holy and pure things, which will replace unholy and impure impulses.
- Philippians 4:8 reads, “Finally, brothers, whatever is true, whatever is honorable, whatever is just, whatever is pure, whatever is lovely, whatever is commendable, if there is any excellence, if there is anything worthy of praise, think about these things.” (ESV)
Third, a person can work to express their anger and attempts at humor in healthy and holy ways. Saying cuss words isn’t authentically dealing with anger, but masking it with a short outburst that dishonors God. Using cuss words to make people laugh also dishonors God.
- 1 Timothy 4:12 reads, “Don’t let anyone think less of you because you are young. Be an example to all believers in what you say, in the way you live, in your love, your faith, and your purity.”
