No, forlorn. Private judgment refers to substituting your judgment for that of the Magisterium, of placing your authority above that of the Magisterium in any and all instances where the Magisterium should be decisive and controlling.
Which is exactly what Struthio did, subjecting Trent to his private judgement. As you'd know if you actually read the argument instead of rushing in to make some half-hearted insult about "doctrinal interpretation", when I never mentioned or alluded to that concept at all.
Now you want to run off on some tangent about sedevacantism because it's easier for you to play sidekick by changing the subject than it is by defending what Struthio actually said, since it's completely indefensible.
So, since you don't like my direct question "how did you decide you don't have a Magisterium?," I'll rephrase it in a way that you seem to be more comfortable with: how did you "find" that the hierarchy of the Conciliar Church is not "where the Church is"?
Unfortunately for you, this is not a "detour." It's an arrow pointed at your heart.
You'll likely dodge again and that will be as good as a direct answer.
Go ahead.
We've been through this before. The question of where the Church is is entirely different to the question of whether or not the Church has authority to teach dogmatically, and it(the former) is one I don't claim to know the answer to. Yes, one has to use their private judgement to find the Church in the first place, and yes the presumption in normal times is that the man who everyone says is the pope, is indeed the pope. We could argue for hours about why he is or he isn't and the theological implications of that.
But none of that defends the proposition that one does not have to accept the dogma of an Ecuмenical Council by a true pope. Whether I'm right or wrong re: the pope is completely irrelevant to this discussion(regarding Trent, which we all agree had a true pope). So I ask, yet again, do you or do you not agree that if a true pope(let's assume we know this with certainty) approves an Ecuмenical Council, that all the dogma defined by that Council are infallibly true?
