Catholic sacramental confession (the Sacrament of Reconciliation) provides explicit structure for reconciliation: (1) Examination of conscience using traditional questions; (2) Sincere contrition; (3) Confession of sins to a priest; (4) Receiving absolution; (5) Performing the assigned penance. The seal of confession is absolute — priests cannot reveal anything confessed, on pain of automatic excommunication. This makes the practice safe for any matter regardless of how serious. Confession is available at any parish; appointment confessions are normal for serious matters where time is needed.
Eastern Orthodox confession
Eastern Orthodox tradition treats confession similarly but with some distinctive features: confession is often described as "before the icon of Christ" rather than to the priest; the priest is witness and spiritual physician rather than judge; the prayer of absolution may be in different forms. Practical structure is otherwise similar to Catholic practice.
Protestant reconciliation practices
Protestant traditions vary widely. Lutherans retain confession in modified form; some Anglican / Episcopal traditions practice formal confession; most evangelical traditions rely on direct prayer to God without clergy intermediation. The 12-step recovery movement's "Fifth Step" (admitting wrongs to oneself, God, and another person) provides a structured Protestant-friendly reconciliation framework outside formal church structures.
All major religious reconciliation practices share structure: (1) Recognition of the act as wrong; (2) Sincere regret; (3) Decision to stop; (4) Resolve to change; (5) For interpersonal harm, restitution where possible. Where they differ: presence/absence of clergy intermediation; the role of formal liturgy vs private practice; specific timeline expectations; the relationship between formal practice and ongoing transformation.
