For us Catholics, we are dogmatic that the Holy Mass involves the real presence of our Lord’s Body and Precious Blood, and that a real propitiatory sacrifice takes place in the celebration of the Eucharist. But what is the nature of the sacrifice? Does Christ undergo a new transition from being a heart-pulsing human body & soul, to losing all the oxygen in his heart and lungs through asphyxiation, all over again and again as we celebrate the Last Supper? Though I doubt anyone would assert this openly, and while the title of this article was meant to catch attention, some of us still have a difficult time explaining just how the Mass brings into the present moment the veritable death of our Lord. Curious minds care to know!
