The council of Florence defined, using its solemn authority, the words of consecration, to make a Mass valid. Paul6 decided to change the words of consecration in his novus ordo. Let's compare to 2 docuмents, to highlight the changes. And to remind everyone, that there is YET ANOTHER reason (among many) to doubt the validity of the new mass.
"The mystery of faith" is a reference to the fact that it is a "mystery" i.e. a sacrament. To remove this phrase is to doubt or deny the sacramental quality of the consecration.

Now let's look at what Paul6 changed it to.
Paul6's changes for the consecration of the wine are:
Of course, Paul6 removed the phrase "Mysterium Fidei" and now it is NOT part of the consecration formula.
According to Pope St Pius V's ruling, this change is a defect of the form and would be (at least) a probable doubt of validity.
Yes to all that you said, Pax. And to add some other important things.
The sentence before your quote from the Council of Florence, we find the following statement:
But since in the above written decree of the Armenians the form of the words, which in the consecration of the body and blood of the Lord the holy Roman Church confirmed by the teaching and authority of the Apostles had always been accustomed to use, was not set forth, we have thought that it ought to be inserted here.
Florence is saying that the "form" that includes the words "
mysterium fidei" is of Apostolic origin, not from a development of mere Church discipline or habit.
And Pius V says the following right after the quote you provided from
de defectibus:
If the priest were to shorten or change the form of the consecration of the Body and the Blood, so that in the change of wording the words did not mean the same thing, he would not be confecting the Sacrament [non conficeret Sacramentum]. If, on the other hand, he were to add or take away anything which did not change the meaning, the Sacrament would be confected [conficeret], but he would be committing a grave sin [gravissime peccaret].
Note that he distinguishes between the ontological defect (
non conficeret = not made
) and the juridical defect (
gravissime peccaret = grave sin). The former is from certain knowledge arising from the intellect based on Apostolic origin. The latter is from the exercise of will based in the juridical power of the Church.
So, the words "
mysterium fidei" came from Apostles. And to leave those words out of the "form" will result in an ontological failure to confect the Sacrament in the Consecration of the Blood.
However, the Consecration of the Bread would still be confected by a true Priest. But as Canon Law (both 1917 and 1983) says, to confect one species without the other is a sacrilege.
Canon 817 (1983 CIC 927)
It is nefarious, even if urged by extreme necessity, to consecrate one matter without the other,
or even both outside of the celebration of Mass.
This is the
intentional sacrilege brought about by the New Mass. This is why the
Novus Ordo is a type of Black Mass.
