High Quality Content by WIKIPEDIA articles! Penance is repentance of sins as well as the proper name of the Roman Catholic, Orthodox Christian, and Anglican Sacrament of Penance and Reconciliation/Confession. It also plays a part in non-sacramental confession among Lutherans and other Protestants. The word penance derives from Old French and Latin poenitentia, both of which derive from the same root meaning repentance, the desire to be forgiven; (in English see contrition). Penance and repentance, similar in their derivation and original sense, have come to symbolize conflicting views of the essence of repentance, arising from the controversy as to the respective merits of "faith" and "good works." Word derivations occur in many languages.
