First: The SSPX does not say that the Novus Ordo is invalid. They say exactly what Fr. Corapi says; that it is valid when it is offered according to the liturgical books promulgated by Paul VI.
Second: Tell me how this is pro-Novus Ordo.
“What happened after the Council was something else entirely: in the place of liturgy as the fruit of development came fabricated liturgy. We abandoned the organic, living process of growth and development over the centuries, and replaced it–as in a manufacturing process–with a fabrication, a banal on- the-spot product.” (Cardinal Joseph Ratzinger) Preface to Reform of the Roman Rite by Klaus Gamber
The fact is the Holy Father can’t undo the damage overnight. So, he’s being politically correct nowadays rather than tell the world that he thinks the Novus Ordo is a fabricated, banal, manufactured product of a committee. (His words, not mine)
There is speculation in some circles that the Paul VI missal will be dumped for what will be known as the new rite of Benedict XVI.
Which will be some kind of an amalgmation of the two missals.
