The critical point beyond which it is impossible to grow without "changing forms" is the awareness that the Mass is the sacrifice of Calvary made present in an un-bloody form. A valid Mass in any form is always the sacrifice of Calvary, but that it's not really understood as such is evidenced by the way people respond to this profound truth (including the clergy).
|Yes, there really is an altar there.|
Once this insight is grasped – the realization that this is Calvary – one has arrived at a point beyond which the Novus Ordo cannot go. All you can do is "change" the Novus Ordo to accommodate the growth of the faithful: you can begin to move towards the Latin version of the Novus Ordo; return to ad orientem worship; introduce the Gregorian chant propers. Once you’ve made these “changes”, you arrive at a point that...well, the extraordinary form already does this, and its durability has proven itself for centuries.
The EF Mass has enough depth that one can never exhaust it. The Novus Ordo, by comparison, is childish and demands that one outgrow it if one aspires to spiritual maturity.
The evidence is in. The dots are able to be connected. We have centuries of evidence that the EF Mass “works”, and the collapse of the Novus Ordo is inevitable. There's just no “there” there. The verdict is in. The liturgical experiment that is the Novus Ordo has failed spectacularly. Sure, there are communities here and there that are growing towards spiritual maturity in spite of the Novus Ordo, but, if they continue to grow, and if they finally see what the Mass is, they won't be able to continue as they are. The EF Mass is the only option left. For those who have already figured this out, why waste time treading water where they are?
