This question arose after the research that went into my answer to According to the Catholic Church, does abortion need to be confessed, and is it a mortal or venial sin? | by Terry.
Are unbaptized and uncatechized candidates for reception into the full communion of the Roman Catholic Church obligated to celebrate the sacrament of reconciliation prior to their profession of faith?
If no, what is the reason and what do they do with their sins prior to baptism?
