I'm reading the short book on the Ottaviani Intervention which was published in 1969 before the Novus Ordo was officially sanctioned. In his letter sent to Pope Paul VI, Cardinal Alfredo Ottaviani wrote:
…the Novus Ordo represents, both as a whole and in its details, a striking departure from the Catholic theology of the Mass as it was formulated in Session XXII of the Council of Trent… [my emphasis, et ad infra]The intervention was not the work of Cardinal Ottaviani alone, but of theologians and other members of the hierarchy concerned about the changes in the Mass that downplayed the elements of sacrifice and even the doctrine of Transubstantiation.
…It is evident that the Novus Ordo has no intention of presenting the Faith as taught by the Council of Trent, to which, nonetheless, the Catholic conscience is bound forever.
The 1992 book on the intervention gives a history that shows the deliberate effort to downplay and change in the Mass those elements that would make it specifically Catholic and a roadblock to ecumenism. So the priest became the "president" of the "assembly" or presider. And the Mass itself became the meal rather than the sacrifice. The Mass-wreckers claimed they weren't changing anything and threw in some traditional language they claimed meant the same as their watered down language, but after the Council the liberals made it clear they did not interpret the changes in the light of Trent -- just as Cardinal Ottaviani said.
As I'm reading the work, I can't help thinking of Amoris Laetitia which seems to be deliberately ambiguous.
Amoris Laetitia: Year One
Once again a handful of courageous cardinals are challenging a pope's actions and the ambiguity that is threatening the faith. As Fr. Murray writes:
They wrote in their April 25, 2017 letter: “Despite the fact that the Prefect of the Doctrine of the Faith has repeatedly declared that the doctrine of the Church has not changed, numerous statements have appeared from individual Bishops, Cardinals, and even Episcopal Conferences, approving what the Magisterium of the Church has never approved. Not only access to the Holy Eucharist for those who objectively and publicly live in a situation of grave sin, and intend to remain in it, but also a conception of moral conscience contrary to the Tradition of the Church.....The escalation of the crisis in the intervening months is clear. The Cardinals note in their second letter that it is no longer simply “theologians and scholars” but now “Bishops, Cardinals and even Episcopal Conferences” that are saying things that contradict the Magisterium of the Church, and this despite the repeated statements by Pope Francis’ own Prefect of the Congregation of the Faith, Cardinal Müller, that the doctrine of the Church has not changed.With Ottaviani's Intervention, the liberals responded to whitewash the concerns of the cardinals and try to make them disappear. Today, the response is silence while the wreckage ensues.
What will happen in all this? It is certainly a time for prayer!
When the Lord returns will there be any faith on the earth?
