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 are 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.
