The Sacrament of Penance, also known as Confession or Reconciliation, allows Catholics to confess their sins to a priest and receive forgiveness from God. Through an act of contrition, confession of sins, and performance of a penance, the priest absolves the sins of the penitent. This sacrament dates back to Jesus giving the apostles the authority to forgive sins. Catholics are obligated to receive this sacrament at least once per year.
