Act of Contrition

O my God, I am heartily sorry
for having offended thee,
and I detest all my sins
because of thy just punishment,
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 sin no more
and to avoid the near occasion of sin.
