Traditional Catholic prayer
Act of Contrition for Confession
Source: With God: A Book of Prayers and Reflections (1911), Francis Xavier Lasance, page 391.
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 have offended 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.
