=Joe17;3535948]**As to Mysterium Fidei, it refers to the precious blood on the altar. **How could it be if Christ died on the Cross ? We believe because Christ has said it. It still has the appearance of wine, but we know by our Catholic faith that it is no longer after consecration. It is by the gift of faith that we believe it, and if I apostasized tomorrow(Lord forbid), it would still be our Lord’s blood even though I did not believe it anymore.
*Mysterium Fidei *refers to transubstantiation. Pope Paul wrote an encyclical called *Mysterium Fidei *because of all the criticism of the New Mass and some were questioning its validity.
Pope Innoncent said the the words Mystery of Faith were given to the apostles by Christ.
Catechism of Trent
“Thus the words, this is the chalice, are found in St. Luke and in the Apostle; but the words that immediately follow, of my blood, or my blood of the new testament, which shall be shed for you and for many to the remission of sins, are found partly in St. Luke and partly in St. Matthew. But the words, eternal, and the
mystery of faith, have been taught us
by holy tradition, the interpreter and keeper of Catholic truth.”

Pope INNOCENT III 1198-1216
The Form of the Eucharistic Sacrament and its Elements *
[From the letter “Cum Marthae circa” to a certain
John, Archbishop of Lyons, Nov. 29, 1202]
414 You have asked (indeed) who has added to the form of the words which Christ Himself expressed when He changed the bread and wine into the body and blood, that in the Canon of the Mass which the general Church uses, which none of the Evangelists is read to have expressed. . . . In the Canon of the Mass that expression, "
mysterium fidei,"is found interposed among His words. . . . Surely we find many such things omitted from the words as well as from the deeds of the Lord by the Evangelists, which the Apostles are read to have supplied by word or to have expressed by deed. . .
415 ….Therefore, we believe that the form of words, as is found in, the Canon, the Apostles
received from Christ, and their successors from them. .
Father Bugnini, who helped write the New Mass wanted “Mystery of Faith” removed completely from the Mass. Pope Paul insisted that it be retained and he decided that it would be placed after the consecration, which is where it is in the Novus Ordo.

“…. venerable brothers, in this very matter which we are discussing, there are not lacking reasons for serious pastoral concern and anxiety. The awareness of our apostolic duty does not allow us to be silent in the face of these problems. Indeed, we are aware of the fact that, among those who deal with this Most Holy Mystery in written or spoken word, there are some who with reference either to Masses which are celebrated in private, or to the dogma of transubstantiation, or to devotion to the Eucharist, spread abroad opinions which disturb the faithful and fill their minds with no little confusion about matters of faith.”
To confirm what we have said by examples, it is not allowable to emphasize what is called the “communal” Mass to the disparagement of Masses celebrated in private, or to exaggerate the element of sacramental sign as if the symbolism, which all certainly admit in the Eucharist, expresses fully and exhausts completely the mode of Christ’s presence in this sacrament. Nor is it allowable to discuss the **mystery of transubstantiation **without mentioning what the Council of Trent stated about the marvelous conversion of the whole substance of the bread into the Body and of the whole substance of the wine into the Blood of Christ, speaking rather only of what is called “transignification” and “transfiguration,” or finally to propose and act upon the opinion according to which, in the Consecrated Hosts which remain after the celebration of the sacrifice of the Mass, Christ Our Lord is no longer present.
Everyone can see that the spread of these and similar opinions does great harm to the faith and devotion to the Divine Eucharist."
