Act of Contrition

An Act of Contrition is a Christian prayer genre that expresses sorrow for sins. It may be used in a liturgical service or be used privately, especially in connection with an examination of conscience. Special formulae for acts of contrition are in use in the Anglican, Catholic, Lutheran, Methodist and Reformed Churches.

The Catholic Church does not restrict the term act of contrition to any one formula. Its Handbook on Indulgences mentions examples of approved formulas for an act of contrition the Confiteor, the Psalm De Profundis, the Psalm Miserere, the Gradual Psalms and the Penitential Psalms.
