I still don't see how you're getting what you're getting from this letter.
The letter to the bishops of Germany from Pope Pius IX is laying out the fact that all the bishops together, i.e. the OUM, CAN teach error.
I'm talking simply about the bishops throughout the world, dispersed (so, not assembled under a council) teaching X in union with the Holy Father. Theologians consider this (with not further qualification or condition) medium of teaching to be infallible, and de fide.
Per Tuas libenter, what Mith wrote is wrong and what Sean has been saying is correct.
Theologians actually do have further qualifications and conditions for teachings to be infallible, these conditions are, per Tuas Libenter, the common and constant consent as being necessary conditions.
If the OUM approve or teach teachings like the NO, we know that infallibility had no part in it because it is new, it is therefore not a constant teaching even if it is a common teaching of the OUM. We know this because this is what pope Pius IX wrote in his letter. He also acknowledged that all the bishops in Germany, the OUM for all intents and purposes if not at least figuratively, certainly could all agree to teach error and actually teach error.
The whole point is that per Tuas libenter, we know the OUM can teach error and we know the qualifications and conditions to know when teachings are fallible or infallible, either way, the jist is that per pope Pius IX, the OUM certainly can teach error.
If the OUM can teach error, why should we trust Tuas Libenter-- whether according to your reading or another?
Tuas Libenter says what it says whether you want to accept it or not - it seems quite obvious you do not. Pope Pius IX therefore, according to you, was either wrong or did not know what he was talking about - either way suffices for you to discount what he clearly teaches, in favor of your adherence to the Chair being vacant. That is what it all boils down to. That's all that really matters to all the sedevacantists I've ever debated and you are no different.
Pope Pius IX knew that when the OUM teach, unless they are teaching something which has always been accepted by the Church as the universal and constant teaching of the Church, that it is not infallible and that without those prior conditions, the danger of teaching error is real.
But according to you and others who have their own idea about what infallibility even is, whatever the OUM decide to teach is automatically going to be infallible no matter what, which is prot thinking, that is not even Catholic thinking, not only that, this is the same line of thinking that helped get us into this mess to begin with.
What Pope Pius IX was warning the bishops about is the very thing you are claiming is an impossibility - he was concerned that they could teach error while you are saying he should have had no worries because it is impossible for them to teach error.
Stubborn, I cited three different theologians who all say the same thing. Sean even agrees with that. YOU are the only one who disagrees with what is being posited. It's the height of arrogance to claim that I'm being protestant. I wonder if you've actually read anything in this thread?
What is protestant is you taking a primary source and privately interpreting it for us, and against the theologians and historical context.
It's not just protestant, it's the height of illogic. Tuas Libentur is not warning against the entire episcopacy falling into error together with the pope, and teaching that error (together, united) to the faithful. He just isn't. Awkward Customer has shown this many times.
But even beyond that, if your argument is that the OUM can teach all manner of error, how on earth do you presume to then cite it in order to present a convincing argument? The OUM is exercised in many different ways, but of the most significant and weighty of these ways (inasmuch as this way is quite easily and sufficiently verified) is when all of the bishops together with their head teach X, X is infallible because for all of the bishops and the pope to err would constitute a defection of the Church. If all manner of error in this expression of the OUM can happen willy nilly, how much more easily and flippantly can it happen when it's "just the pope" teaching? You are truly outstanding, I think I have never met a person with such an amazing lack of circuмspection. There was one guy I talked to who said he's an agnostic because there isn't sufficient proof for God, and then went on to explain that he believes we're all science experiments of aliens from a distant universe. This is up there with that. I'm not going to bend over backwards explaining to you how stupid it is to use a teaching authority that you yourself claims is untrustworthy as evidence that that same teaching authority can be untrustworthy. You're the only one (thankfully) expressing this ridiculous and illogical idea.
Well, yes, I accept the teaching contained in the three quotes/citations you provided from Tanqueray, Ott, and Van Noort.
However, I also stated the following:
"Bossuet’s error consisted in rejecting the infallibility of the pope’s Extraordinary Magisterium; but he performed the signal service of affirming most clearly the infallibility of the Ordinary Magisterium [of the pope] and its specific nature, which means that every particular act bears the risk of error... To sum up: according to the bishop of Meaux,
what applies to the series of Roman popes over time is the same as what applies to the episcopal college dispersed across the world. (Le Gallicanisme de Bossuet, Paris, 1953, p.558)
In fact, we know that the bishops, individually, are not infallible. Yet the totality of bishops,
throughout time and space, in their moral unanimity, do enjoy infallibility. So if one wishes to ascertain the Church’s infallible teaching one must not take the teaching of one particular bishop:
it is necessary to look at the "common and continuous teaching" of the episcopate united to the pope, which "cannot deviate from the teaching of Jesus Christ" (E. Piacentini, OFM Conv., Infaillible meme dans les causes de canonisation? ENMI, Rome 1994, p.37). "
There is no opposition between the position of the quotes you provided, and those I provided; you just didn't dig deep enough to include a discussion of the fallible ordinary magisterium.
However, the two quotes I did provided do directly contradict your contention that:
"I recognize the distinction [i.e., between the fallible and infallible ordinary magisterium -my add], I deny that it applies when a moral unanimity of the episcopacy teaches something in union with their head."
But if:
1) That which "applies to the series of Roman popes over time is the same as what applies to the episcopal college dispersed across the world;
2) And if "it is necessary to look at the common and continuous teaching of the episcopate united to the pope;"
Then it becomes obvious that the teachings of Vatican II (which was certainly an example of the bishops teaching in moral unity with the pope...but not over time, and the substance of their teachings either unheard of in the history of the Church, or condemned) do not belong to the universal infallible ordinary magisterium.
They must necessarily, therefore, belong to the universal fallible/authentic ordinary magisterium.
And this is precisely what Paul VI declared.
