Agreed and well stated.

MSW - you might have wanted to read this post that has experts and came out days before:

Read through the comments - some context:

Paul Inwood was liturgy director for the UK/Wales bishops and says:

"Not only is SP divisive, it was known in advance that it would be divisive. I have said before on this blog that the Bishops of France and England & Wales, who saw the document prior to publication, begged Benedict not to promulgate it. They and their consultants realized how divisive it would be, and what this document would do:

(a) curtail the authority of the bishop as chief liturgist of his diocese;
 (b) encourage proselytising by those who have never accepted the post-conciliar liturgical reforms.

Both of those came to pass.

Note - folks such as Knaweiski from the Wyoming Catholic College are part of the right wing backlash that do not accept VII.
