Reconciliation: Sample Act of Contrition

O my God,
I am heartily sorry for having offended You,
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 You, 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.

My God, I am sorry for my sins with all my heart.
In choosing to do wrong and failing to do good,
I have sinned against you whom I should love above all things.
I firmly intend, with your help, to do penance, to sin no more, and to avoid whatever leads me to sin.
Our Saviour Jesus Christ suffered and died for us. In His Name.
My God have mercy.
