# Transubstantiation ## Catechism of the Catholic Church The scholastic term used to designate the unique change of the Eucharistic bread and wine into the Body and Blood of Christ. "Transubstantiation" indicates that through the consecration of the bread and the wine there occurs the change of the entire substance of the bread into the substance of the Body of Christ, and of the entire substance of the wine into the Blood of Christ--even though the appearances or "species" of bread and wine remain ([[2.2.1.3.p41#^ccc-1376|1376]]).
