Penance (why we confess)

The following is from BustedHalo.com and is part of the Sacraments 101 Series on their website. Visit Busted Halo for more information.
 
Why do we have to confess our sins to a priest? Can't we just pray to God for forgiveness? If I sin but no one is affected then can I say, "no harm, no foul?"

These questions and more are answered in this edition of "Sacraments 101," a web video series geared for those who'd like an introduction or refresher course on these important, tangible Catholic experiences of God.

The Sacrament of Penance (aka Reconciliation) is one of the healing sacraments, and celebrates the loving embrace of God when we turn toward him and away form our sins.
