Act of Contrition
O my God,
I am heartily sorry for having offended you,
and I detest all my sins because of your just punishments,
but most of all because they offend you, my God,
who are all good and deserving of all my love.
I firmly resolve, with the help of your grace,
to sin no more
and to avoid the near occasions of sin.
Amen.
or:
O my God,
I am sorry and repent with all my heart
for all the wrong I have done
and for the good I have failed to do,
because by sinning I have offended you,
who are all good and worthy to be loved above all things.
I firmly resolve, with the help of your grace,
to do penance,
to sin no more,
and to avoid the occasions of sin.
Through the merits of the Passion of our Savior Jesus Christ,
Lord, have mercy.
or:
Lord Jesus, Son of God,
have mercy on me, a sinner.
*From the Order of Penance, nos. 45 and 92.
