You know about FSSP, I'm sure. Then there are a large number of people, amongst whom I include myself, who attend the Novus Ordo every week, but who still have a deep love for the old rite and would attend it ,if made available. Circumstances (i.e. a non-cooperative bishop) often do not allow this.
The Pope recognizes this too. Read Ecclesia Dei. The Holy Father,asked for a "wide and generous" interpretation of its provisions. He knows we're not asking for the suppression of the Novus Ordo.
It may not be necessary, because the Vatican II revolution, like all revolutions, has turned its destructive energies on itself.
The Novus Ordo needs vocations in order to survive. Those dioceses and orders most enraptured by the spirit of Vatican II aren't getting them. The more conservative Novus Ordo diocese and orders, which could be easily become wholly traditionalist, are at least replacing themselves or growing. And traditionalist orders are growing, per capita, at the fastest rate.
Moreover, the old guard who made the Vatican II revolution, who burned the altars while their secular counterparts burned their draft cards, are dying off now. While they have done more damage to the Church than any other group of heretics since the Arians, they have not produced a generation of clerics who share their revolutionary fervour.
Trusting in Our Lord's promise to Peter that the gates of hell shall not prevail against His Church, we may be sure that the Vatican II revolution will be decisively defeated.
