Sin & Confession
Not just a sacrament you receive once a year. A way of living as though every day could be the day you meet Jesus face to face.
For so long, confession felt like something I did to tick a box. A duty. An obligation I fulfilled and then forgot about until the next time it was required of me. It took me a while to understand what it actually is. We are not promised tomorrow. None of us. And we live in a constant state of sin, whether we name it or not. Confession is the gift that lets you keep your soul clean, so that if Jesus calls you today, you are ready. And when you receive communion, you owe it to Him to receive it worthily. That shift in understanding changed everything for me. I hope it does the same for you.

The Starting Point
Understanding Sin
Before we can understand confession, we need to understand what sin actually is. Not as a label. Not as a list of rules broken. But as what it truly does to us and to our relationship with God.
Sin is not simply rule-breaking. At its heart, sin is a turning away from God. It is choosing something other than Him, something lesser, in a moment where He was asking for our trust. The Catechism describes sin as an offense against reason, truth, and right conscience. It wounds our relationship with God, with others, and with ourselves. Original Sin describes the fallen state all humanity entered through Adam and Eve. Personal sin is what each of us adds to that through our own choices. Both matter, and both have a remedy rooted in God’s mercy.
Not all sin carries the same weight. Mortal sin is a grave matter, committed with full knowledge and deliberate consent. It severs our relationship with God completely and requires sacramental confession to restore. Venial sin is less serious but still real. It weakens our relationship with God and, left unaddressed, can gradually harden the heart. There are also sins of omission, the good we knew we should do and did not. And sins of commission, the wrong we actively chose. Both count. Both need to be brought to God.
The Sacrament
Why Catholics Confess to a Priest
This is one of the questions Catholics get asked most often, and one many Catholics have quietly asked themselves. The answer is rooted in Scripture, the early Church, and the profound mercy of God.
On the night of His resurrection, Jesus breathed on His apostles and said: “Receive the Holy Spirit. If you forgive anyone’s sins, their sins are forgiven; if you retain anyone’s sins, they are retained.” (John 20:22-23). This was not a metaphor. He gave the apostles a real authority to forgive or withhold forgiveness, which means real confession of sins was required for that authority to be exercised.
The priest does not forgive you as himself. He acts in persona Christi, in the person of Christ. When the priest speaks the words of absolution, it is Christ speaking through him. The early Church practised confession from its earliest days. This is not a medieval invention. It is an apostolic gift.
There is also something deeply human and healing about speaking your sins aloud to another person. The act of putting words to what you have done, of hearing that you are forgiven, creates a kind of closure that silent private prayer alone rarely achieves. Confession is not a burden. It is one of the most generous things God ever gave us.
A Matter of Reverence
Receiving Communion Worthily
The Eucharist is not a symbol. It is Christ. And receiving Him while in a state of mortal sin is one of the most serious things a Catholic can do.
Saint Paul wrote it plainly: whoever eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty of profaning the body and blood of the Lord (1 Corinthians 11:27). This is not about being perfect before you approach the altar. None of us are. It is about being reconciled.
If you know you have committed a mortal sin, the path is clear. Go to confession first. Not after Mass. Before. This is not a rule designed to exclude you. It is a rule designed to protect you, and to protect the reverence owed to the Eucharist.
Going to confession before communion is one of the most loving things you can do for yourself. It means you are taking both sacraments seriously. And both deserve that.
Step by Step
How to Go to Confession
If it has been a long time, or if you have never been, the process can feel daunting. It is not. Here is exactly what happens, from beginning to end.
Spend some quiet time reflecting on your life since your last confession. Use the Ten Commandments as a guide. Be honest. Be thorough. But do not be scrupulous. God knows your heart.
Most parishes offer confession behind a screen or face to face. Either is valid. Begin with: “Bless me Father, for I have sinned. It has been [time] since my last confession.”
Tell the priest your sins as honestly and completely as you can. For mortal sins, mention the type and approximate number of times. You do not need to be perfect. Just sincere.
The priest will give you a penance, usually a prayer or an act of charity. This is not punishment. It is healing. It helps repair the damage sin has caused and deepens your conversion.
Express your sorrow for your sins to God. If you do not know the Act of Contrition by heart, you can say it in your own words. What matters is that the sorrow is real.
The priest pronounces the words of absolution. In that moment, through the authority Christ gave His Church, your sins are forgiven. Not reduced. Not noted. Forgiven. Leave and do your penance.
Questions People Ask
Things People Wonder About
These are the questions that come up most often, from people who are new to confession and from people who have been going their whole lives.
What God Says
Scripture on Mercy and Forgiveness
These are not comfort verses. They are promises. Read them slowly.
While he was still a long way off, his father saw him and was filled with compassion. He ran to his son, threw his arms around him and kissed him.
If you forgive anyone’s sins, their sins are forgiven; if you retain anyone’s sins, they are retained.
Have mercy on me, O God, according to your steadfast love. Wash away all my iniquity and cleanse me from my sin.
If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness.
