Really, I do wonder if part of the motivation for this particular liturgical change (which I do think is a good one) is to see how long it takes the U.S. bishops to come into comformity. I mean, it should *not* be a contentious point. It's simple and straightforward, and it is clear that it was supposed to take effect immediately.
In St. Louis, I was serving at the cathedral basilica when Archbishop Burke was saying Mass the Sunday after Redemptionis Sacramentum was issued--and he had already implemented all the changes, including this one.
I was sent this a little while ago...and I'm surprised that this happened:
"However, just last night, Wednesday the 19th Archbishop Burke celebrated Mass at the CBC new Chapel with about eighty of us Serrans (St. Louis club) and he used one chalice and the remainder of the wine he consecrated while it was in a glass pitcher until it was poured out after the consecration." I'm not doubting - I heard him on EWTN last Friday, and he was clear about Redemptionis Sacramentum.
