Just to answer this particular question.
+Socrates Villegas is the archbishop of lingayen-dagupan, in the Philippines. He is the current president of the Catholic Bishops Conference of the Philippines.
That would have been obvious, had I read a bit slower.
I am neither a Canon lawyer nor a liturgist. This is not an area I ahve wandered around in, but my recollection (hazy, admittedly) is that a universal norm (was/is) that the laity stand shortly after the Concecration. In the US (well, at least in my archdiocese) we stand after the great Amen; howwever, the deacon stands much earlier - and kneels later.
Perhaps that is only a matter for a deacon. No clue as to why it would be different than the laity, as his standing suits no particular need such as any assist.
What I find interesting (and again, I am not a Canon lawyer) is that the section quoted by the archbishop (# 43) states “…it is laudable to be retained”. That, coupled with the lack of response would seem to indicate that a) it is not mandatory (language could say “it is to be retained”; and b) the lack of response would seem to be different than a response of “No, it is not approved”. It certainly could convey that it is not the wish of the dicastery to approve of the change; but if I am correct that “laudable” represents a preference rather than a requirement, then it would seem that no answer is not necessarily a “no” answer.
There has recently been discussions on another matter for which approval has not been formally given, although the dicastery has been repeatedly asked for a response, and some bishops have taken that as a “no”; others have not required the matter to not be done, while not approving it; and still others have approved it.
Certainly, a more conservative approach is to not vary; but it appears that those who don’t may not have standing to question/disapprove others who take silence as simply that - not approval, and not specific disapproval.
In any event, the archbishop does not appear to be making a decision which is egregious.
However, no matter what the decision, I suspect there will be those who will be unhappy about it and express their displeasure.
As has been said: What is the difference between a liturgist and a terrorist?
You can negotiate with a terrorist…
And FWIW, I believe that quiet acceptance of a bishop’s decision can change the focus from whatever is requested (that is, not making it into an issue), to what is more important: following Christ.
