Verse 20 This cup is the new testament; that is, the wine, representing blood, is the symbol of the new covenant, by which God grants remission of sins through the atoning sufferings of Jesus. The Roman Catholic church understands the expressions, "This is my body," and "This is my blood," (Mark 14:24,) literally, and maintain that when the bread and wine are consecrated by their priests, they become really and truly the body and blood of Christ, although to the senses they remain as before. They accordingly sometimes bear their consecrated elements in processions, and pay divine honors to them.
