Preparing for Confession

Examination of conscience: how to prepare for Confession

An examination of conscience is an honest, prayerful look at your life in the light of God’s word, made before Confession so you can name your sins clearly and receive mercy. Here is how to make one, with questions for adults by the Ten Commandments.

In short

  • An examination of conscience is a prayerful review of your thoughts, words, actions and omissions since your last good confession.
  • Begin by asking the Holy Spirit for light, then go through the Ten Commandments, the precepts of the Church and the duties of your state in life.
  • You must confess every mortal sin you remember, in kind and number; confessing venial sins is not required, but the Church strongly recommends it.
  • Fifteen minutes is usually enough. Aim for honesty, not perfection: a sin you forget in good faith is forgiven with the rest.
  • End with an act of contrition and a firm purpose of amendment, then go to Confession.

What is an examination of conscience?

An examination of conscience is a prayerful review of your life, made before the Sacrament of Reconciliation, to recognize the sins you need to confess. The Catechism asks that Confession be prepared for this way, “in the light of the Word of God”, pointing to the moral teaching of the Gospels and the apostolic Letters, such as the Sermon on the Mount (CCC 1454). In practice, most Catholics examine themselves by the Ten Commandments, which name the matter of serious sin (CCC 1858).

It is not an exercise in self-condemnation. Conscience, the Church teaches, is the place where a person is “alone with God” and hears his voice (CCC 1776). You look honestly at what you have done and failed to do so that you can bring it to the One who is waiting to forgive it. The point of the examination is not the list. It is the mercy that follows.

How to make an examination of conscience, step by step

  1. Find a quiet quarter of an hour

    In a church before Confession or at home the evening before. Silence your phone. Some people write their sins down to remember them; if you do, destroy the paper afterwards.

  2. Ask the Holy Spirit for light

    Pray in your own words, or: “Come, Holy Spirit, show me my sins as you see them, with truth and with mercy, and give me true sorrow for them.”

  3. Go through the questions

    Read the questions below slowly and note honestly what applies since your last good confession. Do not reopen sins that were already confessed and absolved.

  4. Notice what is serious

    For any sin that may be mortal, note what it was and roughly how often (its “kind and number”). If you are unsure whether something was serious, simply tell the priest.

  5. Make an act of contrition

    Tell God you are sorry and resolve, with his help, to avoid these sins and what leads to them. You can use the traditional Act of Contrition.

  6. Go to Confession

    Bring what you found to the priest. If you are not sure what to say, our guide on how to go to Confession gives the words.

What you must confess, and what you may

You are bound to confess every mortal sin you remember after a diligent examination, naming its kind and how many times, “even if they are most secret” (CCC 1456). A sin is mortal when three conditions are met together: grave matter, full knowledge and deliberate consent (CCC 1857). If one is missing, the sin is venial. Our guides to mortal sin and venial sin explain the difference, and our guide to sins to confess shows how to name them plainly.

Confessing venial sins is not strictly necessary, but the Church strongly recommends it: regular confession of everyday faults helps form the conscience, fight bad habits and grow in the life of the Spirit (CCC 1458). And if you sincerely forget a sin, it is forgiven with the others; if you remember a mortal sin later, mention it at your next confession.

Mortal and venial sin, briefly
Mortal sinVenial sin
MatterGrave, as the Commandments name itLess serious, or grave without full knowledge or consent
EffectDestroys charity and the state of graceWounds charity, without breaking friendship with God
In ConfessionMust be confessed, in kind and numberRecommended, not required
Holy CommunionNot before sacramental absolution (CCC 1457)May receive; contrition and the Eucharist forgive venial sins

Examination of conscience by the Ten Commandments

These questions are for adults, and follow the Ten Commandments as the Church numbers them (CCC 2052–2557). They are a mirror, not an accusation: most people will find that only some apply to them. Read each one slowly and stay with the ones that touch something.

1. I am the Lord your God: you shall not have strange gods before me

  • Have I doubted or denied my faith, or put my trust in horoscopes, fortune-telling, spells or superstition?
  • Have I gone a long time without praying, or prayed only out of habit?
  • Have I put money, work, pleasure, a person or my image before God?
  • Have I despaired of God’s mercy, or presumed on it to keep sinning?
  • Have I received Holy Communion while conscious of a mortal sin?

2. You shall not take the name of the Lord your God in vain

  • Have I used the name of God or of Jesus carelessly, in anger or to curse?
  • Have I sworn an oath falsely, or broken a vow or promise made to God?
  • Have I mocked God, the saints or holy things?

3. Remember to keep holy the Lord’s Day

  • Have I missed Mass on a Sunday or holy day of obligation through my own fault?
  • Have I arrived late or left early without a reason, or been deliberately distracted?
  • Have I made Sunday a day of needless work, or kept others from rest and worship?

4. Honor your father and your mother

  • Have I been disrespectful to my parents, or neglected them in their age, illness or need?
  • As a parent, have I neglected my children’s faith, education or well-being, or given them a bad example?
  • Have I failed in the duties of my work, or in my responsibilities as a citizen?

5. You shall not kill

  • Have I harmed anyone physically, threatened them, or wished them harm?
  • Have I held on to anger, hatred or resentment, or refused to forgive?
  • Have I had, encouraged or helped with an abortion?
  • Have I damaged my health by abusing alcohol, drugs or food, or by reckless driving?
  • Have I led someone else into sin by my words or example?

6. You shall not commit adultery

  • Have I engaged in sexual activity outside of marriage?
  • Have I been unfaithful to my spouse, in action or by a deliberate emotional affair?
  • Have I looked at pornography, or committed masturbation?
  • In marriage, have I used contraception, or treated my spouse as an object?

7. You shall not steal

  • Have I stolen anything, or kept what was not mine?
  • Have I cheated in business, at work, in my taxes or my studies?
  • Have I damaged other people’s property without making amends, or wasted my employer’s time?
  • Have I been stingy with the poor, or careless with what was entrusted to me?

8. You shall not bear false witness against your neighbor

  • Have I lied, or deceived someone?
  • Have I gossiped, revealed other people’s faults without need, or spread untruths about them?
  • Have I judged others rashly, or broken a confidence?
  • Have I failed to repair harm I did to someone’s good name?

9. You shall not covet your neighbor’s wife

  • Have I deliberately entertained lustful thoughts or desires?
  • Have I desired another person’s spouse, or encouraged someone else’s infidelity?

10. You shall not covet your neighbor’s goods

  • Have I envied other people’s possessions, success or gifts?
  • Have I let greed or the desire for more rule my choices?

The precepts of the Church

The precepts of the Church are “the indispensable minimum” of prayer and moral effort asked of every Catholic (CCC 2041). The Catechism lists them as: attending Mass on Sundays and holy days of obligation; confessing your sins at least once a year; receiving Holy Communion at least during the Easter season; keeping holy the holy days of obligation; and observing the days of fasting and abstinence, together with the duty to help provide for the Church’s material needs (CCC 2042–2043).

Questions on the precepts

  • Have I gone more than a year without confessing a serious sin?
  • Have I failed to receive Holy Communion during the Easter season?
  • Have I ignored the days of fasting and abstinence, such as Ash Wednesday and Good Friday?
  • Have I neglected to support my parish and the Church according to my means?

The capital sins and your daily life

The seven capital sins (pride, greed, envy, wrath, lust, gluttony and sloth) are not acts in themselves but the roots that many sins grow from. Looking at them helps you see patterns, and choose the virtue to practise against each one. Our guide to the seven deadly sins explains each.

Questions on the roots of sin

  • Pride: Have I been arrogant, unwilling to admit I was wrong, or contemptuous of others?
  • Envy: Have I resented other people’s good fortune, or been glad at their failures?
  • Wrath: Have I lost my temper, nursed grudges or sought revenge?
  • Sloth: Have I neglected my duties or my prayer out of spiritual laziness?
  • Gluttony: Have I eaten or drunk to excess?

After your examination: sorrow, resolution and Confession

Contrition is “sorrow of the soul and detestation for the sin committed, together with the resolution not to sin again” (CCC 1451). It does not have to be a strong feeling. Sorrow that comes from love of God is called perfect contrition; sorrow that comes from fear of sin’s consequences is imperfect, but it is also a gift of God and enough for the sacrament (CCC 1452–1453). Resolve, with God’s help, to avoid the sins you found and what leads you to them.

Then go to Confession and say simply what you found. If anxiety makes you go over the same things again and again, read our guide to scrupulosity and tell your confessor: he will help you find peace.

A short examination at the end of each day

Between confessions, many Catholics make a brief examination each night, often called the examen. It takes five minutes and keeps the conscience gentle and awake, so that the examination before Confession becomes easier.

  1. Thank God for one good thing in the day.
  2. Ask for light to see the day as he sees it.
  3. Look back over the day, hour by hour: where did you love, and where did you fail to?
  4. Tell God you are sorry for what was wrong.
  5. Choose one thing to do better tomorrow, and ask for his help.

Common questions

How long should an examination of conscience take?

For most adults, ten to fifteen minutes is enough before a regular confession. If it has been many years, take longer, perhaps over a few evenings, and do not worry about remembering everything exactly: tell the priest roughly how long it has been and what you remember, and he will help you with the rest.

Do I have to confess every sin I find?

You must confess every mortal sin you remember, saying what it was and roughly how many times. Venial sins do not have to be confessed, but the Church strongly recommends confessing them, because it helps you form your conscience and grow. If you are unsure whether a sin was mortal, confess it and let the priest guide you.

What if I forget a sin in Confession?

If you forgot it in good faith, it is forgiven along with the sins you confessed: the absolution is not undone. If you later remember a mortal sin you forgot, mention it at your next confession. Deliberately hiding a mortal sin is different: it makes the confession incomplete, so speak to the priest about it.

Can I write my sins down and read them in Confession?

Yes. Many people bring a short written list so they do not forget anything, especially when they are nervous or it has been a long time. Keep it private, read from it if you need to, and destroy it afterwards. What matters is that you confess honestly, not that you do it from memory.

How often should I examine my conscience?

Make a thorough examination before every confession, and a short one at the end of each day if you can. The daily examen takes about five minutes: thank God, ask for light, review the day, say you are sorry and resolve to do better. It makes the examination before Confession much easier and more honest.

Is there an examination of conscience for married people?

The questions on this page are written for adults and include marriage under the fourth, sixth and ninth commandments. Married people can also ask how they have loved, respected and forgiven their spouse, how they have shared the work of the home, and how they have passed on the faith to their children.
