Act of contrition 1
O MY GOD, I am heartily sorry for having offended Thee, and I detest all my sins because I dread the loss of Heaven and the pains of Hell; but most of all because they offend Thee, my God, Who art all-good and deserving of all my love. I firmly resolve, with the help of Thy grace, to confess my sins, to do penance, and to amend my life. Amen.
An act of contrition version 2
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 Thy Tender Heart,
O My Savior, let me be freed from the bonds of evil through
the most bitter Passion of My Redeemer. Amen.
O My Jesus, forget and forgive what I have been. Amen.
