Sorrow you can put into words

The Act of Contrition

You can pray this at any hour, in the older words or your own. What the prayer does, and what it leaves for a priest to do, are worth knowing before you say it.

At a glance

  • Say it whenever you need it. There is no wrong hour and no waiting period.
  • No formula is required. A short honest sentence in your own words is a valid act of contrition.
  • Sorrow that comes from fear still counts. Catholic teaching calls it imperfect contrition and treats it as a real beginning.
  • Praying this is not the sacrament of confession. Absolution comes through a priest.
  • This site is software. It cannot hear a confession or absolve anyone.

Short answer

The Act of Contrition is a short prayer of sorrow for sin, prayed near the end of Catholic confession and also on its own. The traditional English form begins O my God, I am heartily sorry for having offended Thee. No exact wording is required. Praying it is real prayer. It is not the sacrament of confession, which involves confessing to a priest and receiving absolution from him.

The traditional prayer, and a plainer way to say it

O my God! I am heartily sorry for having offended Thee, and I detest all my sins, because I dread the loss of heaven and the pains of hell, but most of all because they offend Thee, my God, who art all-good and deserving of all my love. I firmly resolve, with the help of Thy grace, to confess my sins, to do penance, and to amend my life.

If the old words get in the way, here is the same prayer in ordinary English. God, I am sorry. I turned away from you and I want to turn back. Part of my sorrow is fear of what my sin has cost. Most of it is that you are good and I love you. With your help I will confess it, repair what I can, and live differently. Amen.

Then add the thing you actually came here to say. Name it in one sentence, out loud if you are able. I am sorry for what I did to my brother. I am sorry for the way I have been drinking. The prayer does not work better for staying vague.

What each line of the prayer is doing

The prayer moves in four steps, and it opens up once you can see them. It begins with sorrow. It sets the will against the sin, which is the work the word detest is doing. The Council of Trent defined contrition as sorrow of soul and detestation of the sin committed, together with the resolve not to sin again, and the Catechism quotes that line at paragraph 1451. Step three gives a reason for the sorrow. Step four closes with a resolve about what happens next.

So the prayer asks your will to agree with it. It does not ask you to produce a feeling on demand, which is worth knowing if you are praying it dry-eyed and wondering whether that disqualifies you. Heartily is the older word for wholeheartedly and has nothing to do with enthusiasm. Amend my life means change the pattern, so the last clause is about tomorrow morning as much as tonight. Say it slowly once and the shape comes through.

Perfect and imperfect contrition

The prayer gives two reasons for being sorry. One is fear of losing heaven and facing hell. The other is that sin offends a God who is good and worth loving. Catholic teaching has names for these. Sorrow that rises from love of God above everything is called perfect contrition. Sorrow that rises from fear of punishment, or from seeing how ugly the sin is, is called imperfect contrition, or attrition.

Imperfect contrition is treated as a genuine gift of the Holy Spirit and a real start, and it is enough for a valid confession. Plenty of people arrive at this prayer through fear and find that love turns up later. The Catechism of the Catholic Church works through the distinction at paragraphs 1451 to 1453.

The practical effect matters at 2am. You do not have to manufacture a purer motive before you are allowed to pray. Pray with the motive you actually have.

Praying this is not the sacrament of confession

This is the part most pages leave out. In Catholic practice the Act of Contrition is one act inside a larger sacrament. The penitent confesses. The priest gives a penance and speaks the words of absolution. The Catechism presents the priest as a sign and instrument of God's mercy toward the sinner, and binds him to absolute secrecy about everything he hears under what is called the sacramental seal.

So praying these words at home is prayer, and it is worth praying. It is not sacramental confession, because the telling and the absolving are both missing. For a Catholic carrying something serious, the prayer is a step toward the confessional. It does not stand in for it.

PrayWithJesus.ai is software. It has no ordination and no power to forgive sin. It can help you find language, walk an examination of conscience, or rehearse what you want to say before you say it to a person. The priest is the person you can actually go to.

When you cannot get to a priest tonight

Many people look this prayer up near midnight, after something they cannot take back. Catholic teaching answers that moment directly. Perfect contrition, the sorrow that comes from love of God, obtains forgiveness of grave sin when it carries a firm resolve to have recourse to sacramental confession as soon as possible. That resolve is part of what the teaching requires. Leave it out and the condition is not met. This is Catechism paragraph 1452.

Two practical notes follow from it. Someone aware of grave sin is asked to wait for absolution before receiving Communion, apart from the unusual circumstances the Catechism spells out at 1457. And in danger of death any priest can absolve any sin, whatever the ordinary permissions say, which is paragraph 1463.

Between tonight and the confessional, this prayer is yours to pray as often as you want. Sleep is allowed. Parish websites post confession times, and most parishes will make an appointment if the posted hours do not fit your week. The morning is soon enough for the phone call.

When you keep saying it and it never feels like enough

Some people pray the Act of Contrition ten times because it never sounds sincere enough. If that describes you, your sincerity is probably fine. Repeating a confession until the right feeling arrives, going back over sins already forgiven, and needing certainty that a passing thought was not a sin are common features of scrupulosity, and confessors are trained to treat it gently.

The usual counsel is plain. Pray it once, accept it, and stop. Tell a priest or pastor that the loop is happening, in those words, because they can give you a direction you are allowed to obey. If it is eating hours out of your week, talk to a clinician too. Obsessive compulsive disorder often takes a religious shape, and it responds to treatment.

If you are not Catholic

Anglican, Lutheran, Methodist and Reformed churches all keep forms of confession. The Book of Common Prayer sets a General Confession in Morning and Evening Prayer, said by the whole congregation after the minister, including the familiar admission that we have left undone those things which we ought to have done. Anglican and Lutheran practice also retains private confession before a minister, usually as something available and not required.

Most evangelical and Baptist teaching holds that a believer confesses straight to God through Christ with no human mediator required, resting on passages such as 1 John 1:9 and 1 Timothy 2:5. Catholic and Orthodox teaching holds that Christ handed the church a ministry of reconciliation exercised through ordained clergy.

That is a real disagreement about how forgiveness reaches a person, and this page will not settle it. If you are Protestant and these words help you say what you mean, pray them. If you want to know what your own church teaches, your pastor will tell you in five minutes.

Why these words differ from the ones at your parish

If you learned a version that opens by saying you are sorry for your sins with all your heart, you learned the wording from the revised Rite of Penance. That translation is under copyright held by the International Commission on English in the Liturgy, so this page does not reprint it. Your parish, your missal, and diocesan websites all carry it.

The form printed above comes from the Baltimore Catechism approved in 1885, which is public domain and free for anyone to reproduce. Older versions of the traditional prayer differ by more than a hyphen, so do not assume you misremembered.

Vatican News prints a traditional form that reads because of thy just punishments where ours reads because I dread the loss of heaven and the pains of hell, and that ends to sin no more and to avoid the near occasion of sin where ours ends to confess my sins, to do penance, and to amend my life. Both are old and both are used. If you learned that one, you learned it correctly.

The wording is also not the point. There is no single formula a penitent has to recite, and priests routinely invite people to use their own words. In the confessional the priest will tell you when to say it, usually after your penance and just before absolution.

Questions for reflection

  1. 1What exactly am I sorry for, in one sentence?
  2. 2Is my sorrow about the consequences to me, or about the person I hurt, or about God?
  3. 3What would amending my life look like this week?
  4. 4Who do I need to talk to, and when am I going to do it?
  5. 5Am I praying this once, or praying it over and over?

Common questions

What is the Act of Contrition?

A short prayer expressing sorrow for sin and a resolve to change. Catholics pray it near the end of confession and also on its own, and Anglican, Lutheran, Methodist and Reformed churches keep their own confession forms.

Does praying the Act of Contrition forgive my sins?

Catholic teaching says perfect contrition, sorrow that comes from love of God, obtains forgiveness of grave sin when it includes a firm resolve to get to sacramental confession as soon as possible. The prayer alone is not the sacrament.

Do I have to say it word for word?

No. There is no required formula. Sorrow for the sin and a resolve to change are the substance, and your own plain sentence carries both.

When do you say it during confession?

After you confess and the priest gives you a penance, he will usually invite you to make an act of contrition. Absolution follows. If you go blank, say so and the priest will help you.

What is the difference between perfect and imperfect contrition?

Perfect contrition is sorrow that rises from loving God above everything. Imperfect contrition rises from fear of hell or from seeing how ugly the sin is. Imperfect contrition is genuine and is enough for a valid confession.

Why do different websites print different words?

Two reasons. The modern English text comes from the revised Rite of Penance and sits under ICEL copyright, so sites that reprint freely use an older form. The older forms also vary between prayer books, sometimes by a whole clause.

Can I pray this if I am not Catholic?

Yes. It is a prayer of sorrow addressed to God and nothing in it belongs to a priest. Traditions differ on whether grave sin is normally forgiven through a minister, so ask your own church what it teaches.

Can an AI hear my confession or absolve me?

No. PrayWithJesus.ai is software with no ordination and no authority to forgive sin. It can help you find words or prepare for a conversation with a priest or pastor. It cannot replace either of them.
