No. You are taking those phrases out of context. Here is another citation from the same conference:
"The liturgical reform, in its concrete realization, has distanced itself even more from its origin. The result has not been a reanimation, but devastation. In place of the liturgy, fruit of a continual development, they have placed a fabricated liturgy. They have deserted a vital process of growth and becoming in order to substitute a fabrication. They did not want to continue the development, the organic maturing of something living through the centuries, and tehy replaced it, in the manner of technical production, by a fabrication, a banal product of the moment."
That's the Novus Ordo he's talking about, not theories. Here's another representative passage, regarding the new liturgical fashion of eliminating kneelers and kneeling:
"It well may be that kneeling is alien to modern culture--insofar as it is a culture, for this culture has turned away from the faith and no longer knows the One before whom kneeling is the right, indeed the intrinsically necessary gesture. The man who learns to believe learns also to kneel, and a faith or a liturgy no longer familiar with kneeling would be sick at the core. Where it has been lost, kneeling must be rediscovered."
Here he is on versus populi:
"Today celebration versus populi really does look like the characteristic fruit of Vatican II's liturgical renewal. In fact it is the most conspicuous consequence of a reordering that not only signifies a new external arrangement of the places dedicated to the liturgy, but also brings with it a new idea of the essence of the liturgy--the liturgy as a communal meal."
And again:
"A common turning to the east during the Eucharistic Prayer remains essential. This is not a case of something accidental, but of what is essential. Looking at the priest has no importance. What matters is looking together at the Lord. It is not now a question of dialogue but of common worship."
He's not talking about theories--he's talking about the Novus Ordo liturgy--which was what the conference was all about. You are focusing on phrases. You need to understand the whole thrust of his strong criticism at Fontgombault--which included his assertion that the new liturgy violated Trent.
I certainly don’t need to say that I am not one of the "numerous Catholics" who consider it the most appalling horror and a damnable impiety to speak of the sacrifice of the Mass. It goes without saying that the writer did not mention my book on the spirit of the liturgy, which analyses the idea of sacrifice in detail. His diagnosis remains dismaying. Is it true? I do not know these numerous Catholics who consider it a damnable impiety to understand the Eucharist as a sacrifice. The second, more circumspect, diagnosis according to which the sacrifice of the Mass is open to misunderstandings is, on the other hand, easily shown to be correct. Even if one leaves to one side the first affirmation of the writer as a rhetorical exaggeration, there remains a troubling problem, which we should face up to. A sizable party of catholic liturgists seems to have practically arrived at the conclusion that Luther, rather than Trent, was substantially right in the sixteenth century debate; one can detect much the same position in the post conciliar discussions on the Priesthood.The great historian of the Council of Trent, Hubert Jedin, pointed this out in 1975, in the preface to the last volume of his history of the Council of Trent: "The attentive reader ... in reading this will not be less dismayed than the author, when he realises that many of the things - in fact almost everything – that disturbed the men of the past is being put forward anew today." It is only against this background of the effective denial of the authority of Trent, that the bitterness of the struggle against allowing the celebration of Mass according to the 1962 Missal, after the liturgical reform, can be understood. The possibility of so celebrating constitutes the strongest, and thus (for them) the most intolerable contradiction of the opinion of those who believe that the faith in the Eucharist formulated by Trent has lost its value.It would be easy to gather proofs to support this statement of the position. I leave aside the extreme liturgical theology of Harald Schützeichel, who departs completely from catholic dogma and expounds, for example, the bold assertion that it was only in the Middle Ages that the idea of the Real Presence was invented. A modern liturgist such as David N. Power tells us that through the course of history, not only the manner in which a truth is expressed, but also the content of what is expressed, can lose its meaning. He links his theory in concrete terms with the statements of Trent. Theodore Schnitker tells us that an up-to-date liturgy includes both a different expression of the faith and theological changes. Moreover, according to him, there are theologians, at least in the circles of the Roman Church and of her liturgy, who have not yet grasped the full import of the transformations put forward by the liturgical reform in the area of the doctrine of the faith. R. Meßner’s certainly respectable work on the reform of the Mass carried out by Martin Luther, and on the Eucharist in the early Church, which contains many interesting ideas, arrives nonetheless at the conclusion that the early Church was better understood by Luther than by the Council of Trent.
The serious nature of these theories comes from the fact that frequently they pass immediately into practice. The thesis according to which it is the community itself which is the subject of the liturgy, serves as an authorization to manipulate the liturgy according to each individual’s understanding of it. So-called new discoveries and the forms which follow from them, are diffused with an astonishing rapidity and with a degree of conformity which has long ceased to exist where the norms of ecclesiastical authority are concerned. Theories, in the area of the liturgy, are transformed very rapidly today into practice, and practice, in turn, creates or destroys ways of behaving and thinking.
Look at the middle paragraph - that which destroys "ways of behaving and thinking" are the theories that Martin Luther was right instead of Trent. These theories are soundly rejected in the Novus Ordo, which is a true sacrificial liturgy, and also by the GIRM which declares that the NO is a "witness to [the] unchanged faith" of Trent.
I'm not disputing that the Cardinal isn't thrilled with all the allowed changes. But you can't make him say that the NO is evil and destroys the faith - for him to say such a thing while using the Novus Ordo himself would be ridiculous.
