The secretary is wrong. The American Lectionary uses the New American Bible (NAB) translation. Until November 30, the translation in the Living with Christ was the New Standard Revised Version (NRSV) translation, a translation that only Canadians use and it matched our Lectionary perfectly.
The reason we now have a new translation is because the NRSV is forbidden for Liturgy and it’s taken the CCCB close to 15 years to come up with a new translation after being ordered to do so as soon as the Lectionary was published so many years ago.
Now the CCCB didn’t go with the NRSV when it compiled the CBW III. I’m not sure which translation they used but it didn’t match the Lectionary. It still won’t because from what I’ve seen the psalms themselves haven’t changed much, if at all, the changes are in the wording of the responses.
The translation your bishop was expecting in Advent were the changes to the Lectionary because the changes to the Roman Missal are not likely to be seen for at least another year, if not two. The Lectionary translation is approved and it’s what we now find in the Living with Christ and the Sunday Missal. The new Lectionaries themselves have not arrived in the parishes yet.
AFAIK, they haven’t even finished translating all the books for the Roman Missal and they have to submit those to Rome for approval. All we know for sure is that the translation of the Ordinary of the Mass is done and approved and can be seen on the USCCB website.
As for the changes coming to the posture during Mass, I heard Archbishop Prendergast talk of changes that had been agreed upon and instituted by the Atlantic Bishops’ Conference while he was still Archbishop of Halifax. One was kneeling throughout the Eucharistic Prayer. I’ve yet to see that implemented in my Atlantic diocese, in fact, in our parish we stand for the entire EP and the bishop hasn’t even commented on it beyond telling those who complained about it that since it had been requested by the pastor it was the posture to use.
