Baltimore Catechism No. 4 (of 4)
AN ACT OF CONTRITION
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.
The substance of this act is: O my God! I am very sorry for all my sins, because by them I have offended Thee, and with Thy help, I will never sin again. It is well to know what the acts contain in substance, for we can use these short forms as aspirations during the day, when we probably would not think of saying the long forms. A fuller explanation of the qualities of our contrition will be given in Lesson Eighteen.
