Forgive me my sins, O Lord, forgive me my sins; the sins of my youth, the sins of my age, the sins of my soul, the sins of my body; my idle sins, my serious voluntary sins; the sins I know, the sins I do not know; the sins I have concealed for so long, and which are now hidden from my memory. I am truly sorry for every sin, mortal and venial, for all the sins of my childhood up to the present hour. I know my sins have wounded your Sacred Heart, O my Savior, let me be freed from the bonds of evil through your most bitter Passion, my Redeemer. Amen.
Act of Contrition 4
O Lord Jesus, forget and forgive what I have been. Amen.
From the Rite of Penance:
Act of Contrition 5
My God, I am sorry for my sins with all my heart. In choosing to do wrong and failing to do good, I have sinned against you whom I should love above all things. I firmly intend, with your help, to do penance, to sin no more, and to avoid whatever leads me to sin. Our Savior Jesus Christ suffered and died for us. In his name, my God, have mercy.
Act of Contrition 6
Psalm 24:6-7 Remember, Lord, your compassion and mercy which you showed long ago. Do not recall the sins and failings of my youth. In your mercy remember me, Lord, because of your goodness.
Act of Contrition 7
Father of mercy, like the prodigal son I return to you and say: ”I have sinned against you and am no longer worthy to be called your son.” Christ Jesus, Savior of the world, I pray with the repentant thief to whom you promised Paradise: ”Lord, remember me in your kingdom.” Holy Spirit, fountain of love, I call on you with trust: ”Purify my heart, and help me to walk as a child of light.”
Act of Contrition 8
Lord Jesus, you opened the eyes of the blind, healed the sick, forgave the sinful woman, and after Peter’s denial confirmed him in your love. Listen to my prayer: forgive all my sins, renew your love in my heart, help me to live in perfect unity with my fellow Christians that I may proclaim your saving power to all the world.
Act of Contrition 9
Lord Jesus, you chose to be called the friend of sinners. By your saving death and resurrection free me from my sins. May your peace take root in my heart and bring forth a harvest of love, holiness, and truth.
Act of Contrition 10
Lord Jesus Christ, you are the Lamb of God; you take away the sins of the world. Through the grace of the Holy Spirit restore me to friendship with your Father, cleanse me from every stain of sin in the blood you shed for me, and raise me to new life for the glory of your name.
Act of Contrition 11
Lord God, in your goodness have mercy on me: do not look on my sins, but take away all my guilt. Create in me a clean heart and renew within me an upright spirit. Act of Contrition 12 Lord Jesus, Son of God, have mercy on me, a sinner.
