And, by the way, an Ecuмenical Council, is considered a SOLEMN form of Magisterium and not Ordinary.
Absolutely not. It's only SOLEMN if the pope engages his solemn magisterium and defines something infallibly. It's not solemn just because it's ecuмenical. If that were the case, then you would have to change your view and admit that EVERY SINGLE WORD of an ecuмenical council is infallible, which is ludicrous.
If infallibility is not engaged, then it is an act of the ordinary magisterium and can further be either universal or non-universal.
Gallairdetz, American theology professor:There are no clearly developed criteria for determining when a valid ecuмenical council is in fact teaching with the charism of infallibility. This ambiguity has often resulted in an unjustified attribution of infallibility to all conciliar teaching….Dr. William H. Marshner, Professor of Theology at Christendom College and Theological Editor of Faith and Reason, considers Vatican II’s authority in the Fall, 1983 issue of that journal. At the same time, however, I join with all other theologians in saying that the new ground is non-infallible teaching. So when I say that the possibility exists that Vatican II is wrong on one or more crucial points of Dignitatis humanae, I do not simply mean that the Council’s policy may prove unfruitful. I mean to signal a possibility that the Council’s teaching is false.Once they gather together in Council with the approval of a pope, however, the teaching is INHERENTLY UNIVERSAL
It's universal in the sense that it is a teaching of all the current bishops/pope. It also has to be a PERPETUAL teaching of the church in order to be binding. Why do you act as if the history of the Church does not matter? You argue as if an ecuмenical council can change Scripture/Tradition?Let's say, hypothetically, that the Pope and bishops all throughout the world, started teaching that birth control is acceptable. Would this be possible if these were legitimate prelates?
If they did not engage infallibility, then as part of their ordinary magisterium, which does not require unqualified assent, yes, it could be wrong, just like V2 could be (and most likely is) wrong (in some areas). The reason this is possible is because you place too much emphasis on the pope's ordinary teaching authority, which is potentially fallible. Even in the case of V2, with the manner in which the magisterium presented the "decrees" and issued many reservations/qualifications to its "teachings", even today, there is no one in rome who says that V2 MUST be accepted UNCONDITIONALLY. So you are judging the current magisterium as wrong in their ability to interpret their own council! You are presuming it to have more moral gravity than the 'council fathers' say it does! Makes no sense.
What's more likely?
1) There are limits to the ordinary magisterium and it is potentially fallible, even in an ecuмenical council, if they introduce novel and theologically unique ideas.
2) There are no limits to the ordinary magisterium and all must be accepted, therefore infallibility is meaningless, and if an error ever gets put forth by a non-infallible way, then we must presume the entire hierarchy has defected and is no more?.
#2 is infinitely more complex, illogical and improbable than #1.
