The Act of Contrition: the text and why several versions exist
The prayer
O my God, I am heartily sorry for having offended thee, and I detest all my sins because of thy just punishments, 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 sin no more and to avoid the near occasions of sin. Amen.
In short
The Act of Contrition is the prayer of repentance said in confession and in the examination of conscience at night. There is no single formula: several circulate, and what the rite asks for is the sorrow, not the exact words. This is the traditional English form.

When to pray it
In confession, after naming one’s sins and before absolution, and in the examination of conscience before sleeping. It is also the prayer recommended when someone realises something grave and has no way to confess at that moment.
The prayer does three things in two sentences: it acknowledges, it qualifies, and it proposes. Acknowledging is saying what happened; qualifying is saying why it is serious; proposing is saying what changes from now on. An apology that leaves out any of the three tends to ring hollow, and this formula is old enough to know it.
“The near occasions of sin” is the most practical part and the least quoted. A near occasion is the situation that predictably leads back to the same place — the company, the hour, the app, the bar on the way home. The prayer is not asking for willpower: it is asking for a change of route, which is considerably more realistic.
It is honest to say where the Christian traditions separate here, because the disagreement is not in the prayer but in what follows it. Catholic practice ties the act of contrition to sacramental confession, made to a priest. Most evangelical churches confess directly to God on the basis of 1 John 1:9, and treat confession among believers as counsel rather than as a sacrament. The text above is prayed in both settings without a word changing.
One caution about use: this prayer describes repentance, not self-punishment. Repeating the formula over and over, or saying it to relieve a guilt that will not lift, is a sign that the matter may not be a spiritual one. Persistent scrupulosity and disabling guilt are recognised clinical complaints, and seeking professional help for them neither replaces faith nor indicates a lack of it.
Where this prayer comes from
When it appeared Formula fixed between the sixteenth and eighteenth centuries
An act of contrition is not the name of a text but of a gesture: the act by which someone repents. The practice is as old as Christian penance, and the Old Testament already has it in finished form in Psalm 51. What is comparatively recent is the formula — prayers memorised in order to make that act appear in printed catechisms from the sixteenth century onwards, when catechesis began to be done from identical books.
There are several, and all are legitimate. The English form is a cousin of the Latin formula spread by the post-Tridentine catechisms, and a neighbour of the Portuguese one taught in Brazil and of the Spanish one, which differs from both: it opens by addressing Jesus Christ by name rather than God in general. The three say the same things in different orders.
The structure is always the same, and it matters more than the wording: acknowledge what was done, say why it is grave, and propose a concrete change with the help of grace. The Rite of Penance provides several formulas and allows others, or one’s own words — what is asked for is the repentance, not the memorisation.

What the passages say
3Be merciful to me, O God, according to your great mercy. And, according to the plentitude of your compassion, wipe out my iniquity.
4Wash me once again from my iniquity, and cleanse me from my sin.
5For I know my iniquity, and my sin is ever before me.
6Against you only have I sinned, and I have done evil before your eyes. And so, you are justified in your words, and you will prevail when you give judgment.
The text behind the whole Christian penitential tradition — printed here as Psalm 50 because the CPDV follows the Vulgate’s numbering, and as Psalm 51 in the Portuguese and Spanish editions. Note the last verse: “Against you only have I sinned.” It is the same inversion the prayer makes with “most of all because they offend thee”.
13And the tax collector, standing at a distance, was not willing to even lift up his eyes to heaven. But he struck his chest, saying: ‘O God, be merciful to me, a sinner.’
14I say to you, this one descended to his house justified, but not the other. For everyone who exalts himself will be humbled; and whoever humbles himself will be exalted.”
The shortest act of contrition in the New Testament, in one sentence: the tax collector strikes his chest and asks for mercy. Jesus comments on the outcome in the next verse, and the comment is about who went home justified — not about who used the better formula.
18I shall rise up and go to my father, and I will say to him: Father, I have sinned against heaven and before you.
19I am not worthy to be called your son. Make me one of your hired hands.’
20And rising up, he went to his father. But while he was still at a distance, his father saw him, and he was moved with compassion, and running to him, he fell upon his neck and kissed him.
The prodigal son rehearses his speech and never finishes it: the father interrupts him first. Worth reading against the prayer above — the text suggests that the prepared wording matters less than the decision to get up and go back.
8If we claim that we have no sin, then we are deceiving ourselves and the truth is not in us.
9If we confess our sins, then he is faithful and just, so as to forgive us our sins and to cleanse us from all iniquity.
The two verses that ground the practice of confessing, and the verse the evangelical reading rests on when confessing directly to God. The text conditions forgiveness on confession, but the ground it gives is not the effort of the one confessing — it is the faithfulness of the one forgiving.
