The reason that the Rosary was deemphasized after Vatican II was to discourage the pious practice of people attending Mass and praying the Rosary at the same time.
The public was made to know that the Mass was of infinitely more value toward our salvation than the praying of the Rosary, as well intended as it might have been.
One is encouraged to pray the Rosary on his/her own time but not during Mass.
We actually pray the Rosary in lieu of attending the NO. I would consider the NO as detracting from the Rosary — why combine them? Much prefer the Sundays when a Tridentine Mass is available, of course, when we do both (Rosary before and after the Mass).
But that's not what the Pope said. He said that "counting prayers" is pelagianism and thus heretical. This was clear in his scoffing at the "spiritual bouquet" that was offered him by hundreds of the pious.
My point is that if "counting prayers" is wrong in the context of a few thousand rosaries that make up a "spiritual bouquet", then certainly counting each individual Hail Mary and Our Father and Glory Be that make up a single rosary must likewise constitute plagiarism.
It's really very shocking. Even though I'm not a Catholic, I grew up with the simple devotion of the rosary and I feel terribly hurt by being told by this Pope that all of that was not only in vain but was indeed heretical.
I see no way around the conclusion.
