Well, then, you can't really claim to 'love the GIRM' (which by extension includes all pertinent Instructions.)
This is quite simple--it's a zero or a one.
And it is irrelevant to the discussion whether the Vatican leftyliturgywonk emplaces such foolishness in Papal ceremonies. We know who he is (you posted an NCR article about him...) and he's a jerk.
"Well, THEY do it" is precisely the excuse my children have tried to use--as I assume yours may have, too. What was YOUR reaction to that one?
When the guys who write the rules don't observe the rules, what is one to think of the rules?
Niner, I can't name one priest, off the top of my head, who doesn't, on occasion, add some commentary or words to some part of the Mass. I've even seen it done on EWTN!!
If the bishops want it to stop, they need to stop doing it themselves.
I think you are missing the pattern of leftist thought. They only demand strict adherence to those norms which are considered sufficiently liberal. They have no problem playing fast and loose with "rules" which are just too constrictive or "outdated", or which are still tainted with the old theology (the few that are left).
After all, they have found in the past that if they simply don't pay attention to this or that rule for long enough, the rule will be changed or completely eliminated.
