What is there to say except utter nonsense.

The extraordinary form clearly communicates only the understanding of the Mass at a particular point in history.

We know that this understanding is impoverished, in terms of the fuller history of the Eucharist.

In the light of this knowledge, Vatican II acted.


Sorry, but the real argumentation is not that the extraordinary form clearly communicates Catholic doctrine;
on the contrary, it is if you think the Extraordinary form does this, you have a minimal understanding of Mass.
