No text of the remarks of the Apostolic Nuncio yet, but here's the text of the address from the Bishop of Leeds, Arthur Roche, chariman of ICEL, to the USCCB:
The version of Mass that we currently use is clearly far from perfect. Those of you who celebrate Mass in both Spanish and English will know only too well the difference in richness between the two texts. The then bishops of ICEL recognised that from the beginning, and they knew that a revision would be needed. There was an urgent feeling in the early 1970s that the liturgy should be made available to the people as soon as possible, and the work was rushed. The revisiting of this was delayed for practical reasons, but also for ideological ones that caused many bishops grave concern, and that is sometimes forgotten. The chief preoccupation in many minds was, of course, that the liturgy be brought closer to the people. This aim could, and sometimes did, obscure the other aim, which was to preserve and transmit our inherited liturgical tradition and bring our people closer to that. During the initial stages of consultation on the third edition of the Missale Romanum, two theologians wrote to me, quite independently, and shared with me their belief that the Mass texts we currently use had severely diminished our appreciation of the richness of Eucharistic theology. This is clearly something to which we, as bishops, should be sensitive. The Holy Father said something similar during the course of last year’s Synod of Bishops. Of course, if you try to carry a cup of coffee across a room too quickly, much of the contents may spill. This time, we have tried to keep the coffee in the cup.
We are at a very important moment in the whole of this process. If the bishops of the English-speaking countries can agree on a single version of the Mass, what a sign of catholicity that will be. But more than that, it will be a guarantee of catholicity for the future, not only in our own time, and not only in our own countries. Clearly I, and all my brother bishops of ICEL, believe that you, the bishops of the United States, have a most important role of leadership to play in just that. Thank you for giving me your attention.
There's much more - detailed analysis of several key passages to make his points. Worth a read. It will be fascinating to see how the vote comes out.
