Venerable Fulton Sheen
“The Sacrifice of Calvary was offered up in a bloody manner by the separation of His blood from His body. In the Mass, this death is mystically and sacramentally presented in an unbloody manner, by the separate consecration of bread and wine. The two are not consecrated together by such words as ‘This is My Body and My Blood’; rather, following the words of Our Lord: ‘This is My Body’ is said over the bread; then, ‘This is My Blood’ is said over the wine. The separate consecration is a kind of mystical sword dividing body and blood, which is the way Our Lord died on Calvary.”
