Meanwhile, on the other side of the house, we just can't get it together because people are still fighting the battles of 500 years ago, viz.
Tonight I'm not touching that old tar-baby. But here's an even better bet. The Last Supper itself was no Eucharist, no Mass. When Our Lord said "This is my body" he didn't know what he was doing because it just couldn't be his body:
It would only lead to heresy, in my opinion, to posit that when Jesus said at the Last Supper: “This is my body,” the bread became his body. What body did it become? His physical body? That is heretical. His resurrected body? More likely… except the resurrection had not happened yet. Catholic theology has always taken temporality and history very seriously, so I think it is important that we not think that Jesus could somehow offer himself to his disciples in his resurrected form before the resurrection had even taken place!
So, the events of the Upper Room were only [a]n eschatological banquet enacting a surrogate for sacrifice. Jesus declared invalid in light of Catholic theology. Wow.
Whenever and wherever we humans wade in, disaster is sure to follow. We mix truth and falsehood together and call it good. Too bad because this part strikes me as right on the money (my emphases):
There has been a danger in post-Tridentine theology to speak of the Mass as a re-presentation of the sacrifice of Christ. But this interpretation both fails to take the book of Hebrews seriously and also misunderstands the Jewish concept of “remembrance,” azkarah. Jewish remembrance does not mean that the past event is brought into the present and enacted again. Rather, it means that those who partake in the ritual action are themselves re-presented to the past event. At the Mass, the community of believers becomes present to the Paschal Mystery. Christ is not re-offered or re-presented on the altar of the priest. Rather, the believing community is re-presented to the sacrifice of Christ and, through the power of the Spirit, made part of that self-offering to the Father.
