Your First Confession: Exactly What to Say, Word for Word

First: when converts actually make their first confession

This depends on which door you entered by, and the difference is enormously comforting to get straight:

If you are a candidate — already validly baptized, being received into the Church — you make your first confession before your reception. The rite of reception itself provides that candidates confess beforehand, telling the confessor they are preparing to be received into full communion; in practice your parish schedules it during Lent, often at a parish penance service or a quiet appointment. Your OCIA coordinator arranges this — you will not be left to figure it out alone.

If you are a catechumen — baptized at the Easter Vigil — your situation is different in the best possible way: baptism itself wipes everything. The Church teaches that in baptism all sins are forgiven, original sin and every personal sin, and every punishment for sin, with nothing left behind (CCC 1263). You do not confess before the Vigil, because there will be nothing on the ledger. Your first confession comes sometime later — and it covers only what happens after your baptism.

The room (and the choice nobody tells you that you have)

Most confessionals today are small rooms with two options inside: a chair facing the priest, and a kneeler behind a screen. The choice is yours — always. Face-to-face or anonymous behind the screen; walk in and take whichever seat you want, no explanation needed. Many converts choose the screen for a first confession precisely because it removes the fear of being seen nervous. Both are fully valid, and the priest genuinely does not care which you pick.

Confession times are published in every parish bulletin and website — commonly Saturday afternoons — and you can simply show up and wait your turn in line, like everyone else. For a first confession, though, our honest recommendation is to book an appointment with the priest instead. A first confession covering years deserves room to breathe, and an appointment means no line forming behind you while you take it. Priests set aside time for exactly this, and gladly; the Saturday line remains perfectly valid if an appointment feels like too much ceremony.

The script, start to finish

Here is the whole exchange, in order. Bring this on paper or on your phone if you want — priests see notes in confession every single day.

1. 1The priest greets you and will usually begin the sign of the cross: “In the name of the Father, and of the Son, and of the Holy Spirit.” Cross yourself and say “Amen.”
2. 2You say: “Bless me, Father, for I have sinned. This is my first confession.” That second sentence changes everything about what follows — the priest now knows to guide you through every step, and he will.
3. 3Confess your sins, plainly, by kind and (approximate) number. “I lied to people I love — often.” “I used God's name in anger.” “I was unfaithful to my wife, twice.” No essays, no euphemisms, no self-defense — and no theatrical self-condemnation either. Name the thing simply and move to the next. When you're done: “For these and all my sins, I am sorry.”
4. 4The priest may ask a gentle question or two, and will offer counsel — usually brief, usually kind, sometimes startlingly wise. This is not an interrogation; it is a doctor making sure he understands the wound.
5. 5He gives you a penance — typically a few prayers or a small concrete act. If you don't recognize a prayer he names, say so; he will pick another. Accepting the penance is your part of repairing what sin damaged.
6. 6He asks you to make an Act of Contrition. This is a short prayer expressing sorrow — the full text is in the box below, and a printed card is usually sitting right there in the confessional. You can read it. Nobody expects a convert to have it memorized.
7. 7He absolves you. You'll hear words very close to these: “God, the Father of mercies, through the death and resurrection of his Son has reconciled the world to himself and poured out the Holy Spirit for the forgiveness of sins; through the ministry of the Church may God grant you pardon and peace, and I absolve you from your sins in the name of the Father, and of the Son, and of the Holy Spirit.” You say: “Amen.” At those words, it is done — every sin you confessed, and every one you sincerely forgot, is forgiven.
8. 8He dismisses you — often “Give thanks to the Lord, for he is good” (you answer: “His mercy endures for ever”) or simply “Go in peace.” You say: “Thanks be to God,” and you walk out lighter than you walked in. Then go do your penance, ideally right there in the church while it's fresh.

What you must confess — and what you're welcome to

The Church draws a line here that takes real pressure off, and it is worth knowing before you walk in. What you are required to confess are grave sins — what the Church calls mortal sins: the serious matters, done with full knowledge and deliberate consent, that you are aware of after examining your conscience (CCC 1457). Everyday faults — venial sins, the ordinary friction of an imperfect life — you are welcome to confess, and the Church warmly recommends it as a help to growth, but they are not strictly required, and leaving one out breaks nothing (CCC 1458). If you cannot tell which category something falls into, say so right there in the confessional; sorting that out is part of the priest's job, and nobody expects a convert to arrive with a canonist's vocabulary.

“What if I forget something?”

You will forget something. Everyone does, and the Church planned for it: sins genuinely forgotten are forgiven by the absolution. You walk out fully absolved, not provisionally absolved. What the Church asks is honesty, not total recall — the requirement is to confess the serious sins you are aware of after a reasonable examination (CCC 1456). Forgetting breaks nothing. What would break the confession is deliberately hiding a serious sin — or coming with no sorrow at all, which is not your problem if you're reading this.

If a forgotten serious sin surfaces in your memory next week, simply mention it in your next confession: “Father, this came to mind since my last confession.” Routine, undramatic, done.

“What if the priest judges me?”

Two facts, both solid. First: he has heard everything. A priest who has sat in a confessional for even a few years has heard every sin you can name and many you can't. You will not shock him, you will not be memorable for your sins, and priests consistently describe hearing confessions — especially first confessions and long-awaited returns — as the most hope-filled part of their ministry. They watch people put down weight in that room. It does not get old.

Second: the seal of confession is absolute. A priest can never repeat anything you confess — not to police, not to a court, not to your spouse, not to you outside the confessional unless you raise it, not under threat of imprisonment or death. The Church calls this the sacramental seal and admits no exceptions (CCC 1467); her law declares it inviolable, full stop (Canon 983). Priests have gone to prison and to their deaths rather than break it. What you say in that room stays sealed forever.

“How do I even remember 30 years of sins?”

You don't — not exhaustively, and God is not auditing you. The tool for this is an examination of conscience: a structured set of questions, usually walking through the Ten Commandments, that you pray through slowly in the days before. It surfaces what actually needs saying and gives you a natural outline. Use our examination of conscience, write brief notes as you go, and bring the notes in with you. And if the worst happens — you sit down and every word leaves you — you may simply hand the priest your written list and let him guide you through it. Priests have seen this before, and it is a perfectly acceptable way to begin. Tear it up afterward: the mercy stays; the paper doesn't need to.

Then confess by kind and number, as best you can — and for a first confession covering decades, approximation is expected: “many times,” “over about ten years,” “more times than I can count.” The Church's own standard is the sins you are conscious of after a sincere examination — not a forensic accounting of a lifetime (CCC 1456). Say what you found, say it plainly, and let the mercy of God handle the archive. That is precisely what it is for.
