CCC 1452

When it arises from a love by which God is loved above all else, contrition is called "perfect" (contrition of charity). Such contrition remits venial sins; it also obtains forgiveness of mortal sins if it includes the firm resolution to have recourse to sacramental confession as soon as possible. Cf. Council of Trent (1551): DS — Denzinger–Schönmetzer (Enchiridion Symbolorum).
