Is it a sin to masturbate?
The Bible never addresses it, and the guilt is usually louder than the text
In short
No passage in the Bible addresses masturbation. The verse most often cited, about Onan, is about refusing a family duty and is not about the act people think it describes. What Scripture does address is lust, and that is a different question, which is why traditions differ.
What the text says
And Onan knew that the seed should not be his; and it came to pass, when he went in unto his brother's wife, that he spilled it on the ground, lest that he should give seed to his brother.
1 Corinthians 6:12 was the verse of the day on September 18, 2021. See that day
Often brought inMatthew 5:28
But I say unto you, That whosoever looketh on a woman to lust after her hath committed adultery with her already in his heart.
Jesus addresses lust, which is the real question for most people here. Whether the act necessarily involves it is exactly where the disagreement lies.
The counterweight1 Corinthians 6:12
All things are lawful unto me, but all things are not expedient: all things are lawful for me, but I will not be brought under the power of any.
Paul's test for a disputed matter: not permitted or forbidden, but whether it has come to master you. That framing fits this question better than most.
What Christians agree on
Lust is addressed directly by Jesus, and pornography involves real people and real harm. Being controlled by any compulsion is a genuine concern. Nobody claims the Bible names this act.
Where they disagree
Catholic teaching
The act is disordered because it separates sexual pleasure from its purpose within marriage. This is a conclusion from natural law and church teaching rather than from a verse.
Much evangelical counsel
The act itself is not named in Scripture; the lust that usually accompanies it is. Address the lust, and the question mostly answers itself.
Those who focus on compulsion
The useful question is whether this is something you do or something that does you. A habit that governs your mood and your time has already answered it.
Questions worth asking
- Is this tied to pornography, and would that be the harder thing to face?
- Do I feel guilt about the act, or about something I was told and never examined?
- Is there an adult I trust enough to say this out loud to, once?
If you are young and reading this at two in the morning after searching in private, the most useful thing this page can tell you is that the Bible does not mention it, that you are not uniquely broken, and that shame is a poor teacher. There are people worth talking to about this, and the conversation is less terrible than the silence.
