I have said and will continue to say that the "dogma of the faith" refers to the Eucharist and secondarily that only some souls will be saved, not all.
Why will this dogma be retained in Portugal? Because Portugal was one of only two nations (Poland is the other) whose Bishops Conference correctly translated the Novus Ordo words of consecration "pro multis" into the vernacular as "for many".
I believe it is possible that the mistranslation "for all" invalidates the consecration and thus Portugal is one of the few places where the vernacular New Mass is valid and thus the "dogma of the Faith", the Eucharist, is maintained.
In addition it reaffirms the vision Our Lady showed the children of Hell inhabited by demon and human souls.
I think it is an admonition that the Church will move towards universal salvation (JPII's position was very close to it, so is modern ecuмenism) gutting the dogma of the faith (necessity of faith in Jesus Christ for salvation), but in Portugal it will at least continue to exist.
My theory anyway...

By Rev. Fr. Peter R. Scott
...This particular change in the words of consecration, the most serious in the New Mass, was not a part of the New Mass as "promulgated" (Note that properly speaking it was not really promulgated, both from the point of view of the formalities involved and from that of content) by Pope Paul VI on April 3, 1969 in his letter Missale Romanum. In the Latin text the words "for many" are retained. This change is consequently one of translation. However, it was manifestly not by accident that in all the modern European languages except Portuguese and Polish this same "error" of translation was committed. It is a manifest effort to undermine the clear teaching found in all three synoptic Gospels that the efficacity of Christ's shedding His blood is limited to many souls, and not to all souls. The reason behind this change is consequently the modernist teaching on universal salvation, according to which Christ saved all human nature by his death on the Cross, whether people know it or not.
Since this is a change that manifestly undermines Catholic doctrine, it is equally clear that the traditional Catholic cannot accept it...
