Is Getting Drunk a Mortal Sin? Catholic Teaching
The Catholic Church teaches that drunkenness is a sin against the virtue of temperance, and it can be a mortal sin. Whether a particular night of drinking was mortal depends on three things the Church always asks about: how grave it was, whether you knew it was seriously wrong, and whether you freely chose it. The place to sort that out is confession, and the door to confession is always open.
If you want the general Bible answer, read Is getting drunk a sin? This page is about what the Church teaches and what to do as a Catholic.
What the Catechism says
The Catechism of the Catholic Church speaks of temperance as the virtue that keeps our appetites in order. Paragraph 2290 names the abuse of alcohol as one of the excesses temperance guards against. It adds a hard line: people who put others in danger through drunkenness, behind the wheel or anywhere else, carry grave guilt.
So the Church doesn’t treat a drink as a sin. Wine is used at every Mass. What the Church names as sin is drinking past the point where reason and self-control are gone.
St. Thomas Aquinas, whose teaching shaped much of the Catechism, said drunkenness becomes mortal when a person knows the drink will take away their reason and chooses it anyway. Someone caught off guard by a strong drink is in a different place from someone who sets out to get drunk.
The three conditions for mortal sin
Paragraph 1857 of the Catechism gives three conditions. All three must be present.
- Grave matter. The act itself is seriously wrong. Getting fully drunk can be grave, and it’s clearly grave when it puts other people at risk.
- Full knowledge. You knew it was seriously wrong.
- Deliberate consent. You chose it freely.
Paragraph 1735 adds that habit, fear, strong attachments and other factors can lessen how responsible a person is. For someone caught in addiction, this matters. It doesn’t mean the drinking is fine. It means God sees the whole picture, and the Church doesn’t ask you to judge yourself alone.
Why this question can become a trap
Many Catholics who drink too much spend a lot of energy on one question: was it mortal or venial? It’s a fair question, and a priest can help you answer it. But it can also become a way to avoid a bigger one.
If you’re asking about mortal sin more than once a month, the bigger question is whether alcohol has a hold on you. Our page on signs of alcoholism can help you look honestly.
Safety first. If you drink heavily every day, stopping suddenly can be dangerous. Talk to a doctor before you quit.
How to confess drinking
Confession doesn’t need a speech. You might say something like:
- “I got drunk twice since my last confession.”
- “I drove after drinking.”
- “I said cruel things to my wife while I was drunk.”
- “I think I have a drinking problem, and I keep falling.”
That last sentence is worth saying out loud. A good priest will not be shocked. He has heard it before, and he may know where local help is.
If you’re making a fuller confession after years of drinking, it can help to write a list first. People working the Twelve Steps do something similar in their written inventory and in Step 5, where they admit their wrongs to God and another person. Many Catholics find the two fit together well.
“If we confess our sins, he is faithful and just to forgive us our sins and to cleanse us from all unrighteousness.”
Grace, not just rules
The Church’s teaching on mortal sin is serious because grace is serious. The point is not to keep you away from God. It’s to bring you back to Him fully, through the sacrament He gave for exactly this.
“And he arose and came to his father. But while he was still a long way off, his father saw him and felt compassion, and ran and embraced him and kissed him.”
The father in that story saw his son from far off and ran. That is how God receives a person walking into a confessional.
Saints who know this road
Catholics have an intercessor who knew the bottle well. Venerable Matt Talbot was a Dublin laborer who drank heavily from his teens. In 1884 he took a pledge to stop, and with prayer, daily Mass and hard discipline he stayed sober until his death in 1925. Many Catholics in recovery ask for his prayers. St. Monica, who prayed for years for her son Augustine, is often asked to pray for families. See our Catholic prayer for alcoholics.

Common questions
What does the Catechism say about drunkenness?
The Catechism of the Catholic Church (paragraph 2290) teaches that the virtue of temperance helps us avoid every kind of excess, including the abuse of alcohol. It says people who endanger others through drunkenness, for example on the road, incur grave guilt.
Do I have to confess getting drunk?
If you believe it was a mortal sin, the Church asks you to confess it before receiving Communion. Even if you're unsure, bringing it to confession is a good thing to do. The priest can help you sort out how serious it was.
Is it still a mortal sin if I'm an alcoholic?
The Church teaches that habit, attachment and other factors can lessen a person's responsibility for an act. That doesn't make drinking fine. It means the honest place to work this out is with a priest, and the honest next step is getting help.
Can I receive Communion after getting drunk?
