Nevertheless, in Catholic thought, the exemption of the See of Rome from all error extends only to its definitive teachings on faith and morals, not to its historical judgments. Similarly, papal sainthood does not suggest that popes are free from sin. Quite the contrary, popes frequent the sacrament of Reconciliation (confession and penance) for the forgiveness of their sins, as all other Catholics are required to do. While occupying the papal office, Pope Benedict XVI confessed his sins once a week.
