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.
Amen.
