An 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.

“[T]he holy Synod declares, that this contrition contains not only a cessation from sin, and the purpose and the beginning of a new life, but also a hatred of the old… [A]lthough it sometimes happen that this contrition is perfect through charity, and reconciles man with God before this sacrament be actually received, the said reconciliation… is not to be ascribed to that contrition, independently of the desire of the sacrament which is included therein. (Council of Trent, Session XIV, Decree on the Sacrament of Penance, chapter iv. Emphases supplied.)
