What is the proof of that? Why does Ratzinger (one of the "progressives" during the Council), not reflect the thinking of the committee?
Ratzinger does reflect the committee. As I have noted, he does not believe that an actual immolation takes place. To him the sacrifice involves no destruction but celebrates man's transformation. For more on this cf: "Considerations on Cardinal Ratzinger's Fontgombault Conference" by Fr. Patrick De la Roche, The Angelus, April 2002.
