My fiancee and I are currently in marriage prep in the Catholic Church, and thus our officiant asked for our baptism certificates from our respective churches. When he contacted my fiancee’s church where she received all of her other sacraments, they had no record of her being baptized. We’re currently working to find documentation of this, but if she somehow has not been baptized, what would that mean for her other sacraments? Are they invalid? Does she just have to be baptized to make the other sacraments valid, or would she have to receive those sacraments again?
