Quick Answer
After confession you should first pray the penance the priest assigned, even if it is a short one, and you should do it as soon as you can, ideally before leaving the church. Then it is traditional to pray a personal prayer of thanksgiving, which can be as short as "Thank you, Lord, for forgiving me" or as formal as a slow Glory Be.
Many Catholics also pray a second Act of Contrition, ask for the grace to avoid the same sin again, and offer the rest of their day in reparation for what they have just confessed.
Step 1: Do Your Penance Right Away
The penance is part of the sacrament. If the priest said "three Hail Marys," go straight to a pew and pray three Hail Marys slowly, not in a rushed mumble on the way out the door. If he gave you a longer act, like reading a Psalm or doing something concrete during the week, mark it down on your phone before you leave so you actually do it. Skipping the penance does not invalidate the absolution, but it is a missed opportunity and a small disobedience inside the sacrament itself.
Step 2: A Short Prayer of Thanksgiving
Mercy is a gift, not a transaction. Take a moment to thank God for it. Any of these works:
- "Thank you, Father, for forgiving me. Thank you, Jesus, for paying the price. Thank you, Holy Spirit, for bringing me back."
- A slow Glory Be: "Glory be to the Father, and to the Son, and to the Holy Spirit, as it was in the beginning, is now, and ever shall be, world without end. Amen."
- The Suscipe of St Ignatius if you want to make a fuller offering of yourself.
Step 3: A Second Act of Contrition If You Need It
Some people find it helpful to pray the Act of Contrition a second time in their own words after they leave the confessional. Not because the first one did not count, but because the words sound different on the other side of absolution. Try: "Lord, I am sorry I hurt You. I am grateful You forgave me. Help me not to do it again, and when I am tempted, remind me how clean I felt right now."
Step 4: Ask for the Specific Grace
Confession is not just a wash; it is a chance to ask God for the grace not to repeat the same sin. If you confessed anger, ask for the grace of patience by name. If you confessed lust, ask for purity by name. If you confessed pride, ask for humility by name. Naming the virtue you want is part of cooperating with the grace you have just received.
Step 5: A Marian Prayer or Closing Sign of the Cross
Many Catholics close with a Hail Mary or a Memorare, asking Mary to keep them close to her Son. A slow Sign of the Cross is the simplest closing, and it is the right physical bookend to the sacrament that just happened.
What to Do With the Rest of the Day
Do not immediately go and recreate the situation that got you into the sin in the first place. If you confessed gossip, plan how you will dodge the same conversation at work on Monday. If you confessed bingeing on alcohol, do not stop at the bar on the way home. Confession resets the soul; it does not reset the environment. The post confession prayer asks God for the wisdom to change what needs to change.
Common Questions
Do I have to pray the exact penance the priest said?
Yes, and ideally on the same day. If you genuinely cannot remember, return to the same parish, explain to a priest, and accept a replacement penance.
What if I forgot to confess something?
If you genuinely forgot a serious sin in good faith, it was still forgiven, but mention it the next time you go.
How long should I stay in the pew?
Five minutes is plenty. The point is presence, not length.
One Last Tip About Saying What You Said
People often ask, "Do I have to literally pray the words the priest gave me?" In short, yes. If he said "five Hail Marys," pray five Hail Marys. If he assigned a corporal work of mercy or a specific reading, do that. Substituting a long mental prayer for the five Hail Marys defeats the purpose, which is obedience inside the sacrament. The prayer you say after confession matters because it is the first act of the new life that just started.
If you walk out and immediately forget the penance, return to the parish on the same day if you can and ask any available priest to confirm or replace it. Most priests will simply say, "Pray three Hail Marys for the same intention." Done.
Bottom Line
The prayer after confession is, in order: your assigned penance, a short thanksgiving, an optional second Act of Contrition, a specific request for the virtue opposite to the sin you confessed, and a closing Marian prayer or Sign of the Cross. Keep it slow, keep it specific, and let the relief actually land before you walk back into your week.
