Evening Act of Contrition
Catholic
O my God, I heartily repent, and am grieved that I have offended Thee, because Thou art infinitely good, and sin is infinitely displeasing to Thee. I humbly ask of Thee mercy and pardon, through the infinite merits of Jesus Christ. I resolve, by the assistance of Thy grace, to do penance for my sins, and I will endeavor never more to offend Thee.
