Transubstantiation

Transubstantiation is a doctrine central to Roman Catholic belief regarding the Eucharist, or Holy Communion. It teaches that during the Mass, the bread and wine used in the sacrament become the actual body and blood of Jesus Christ, while retaining their physical appearances of bread and wine. This change is believed to occur through the words of consecration spoken by the priest. Essentially, while you see and taste bread and wine, Catholics believe that their true essence is transformed into Jesus himself. This belief emphasizes the sacredness of the Eucharist in the Catholic faith.
