It is Catholic teaching that the entire Hierarchy, the Ordinary and Universal Magisterium of the Church, cannot defect, die or disappear. Wilhelm and Scannell, for e.g. write, "The Indefectibility of the Teaching Body is at the same time a condition and a consequence of the Indefectibility of the Church ... the Teaching Body as a whole could not die or fail without irreparably destroying the continuity of authentic testimony." Where is this Teaching Body of the Church today, per SVs and others? Is it found among diocesan Bishops or not?

This ^^^ is novus ordo thinking, but if it were true, then we are all bound under pain of mortal sin to be novus ordo.  

While the indefectibility of the Magisterium is Catholic teaching (although one could argue about its scope), and not mere Novus Ordo thinking, you are quite correct that XavierSem is inconsistent with his own principles and therefore guilty of formal schism.

It is actually something more than just novus ordo thinking, it's more like a novus ordo doctrine that the hierarchy is itself, the (indefectible) universal magisterium. The Church's magisterium has been made into a completely confused idea, it's to the point that I have only seen a very few who got it correct, most do exactly what the OP did - which would make 1) the teaching of today's NO hierarchy ("universal magisterium") true Catholic teaching - which necessarily would make 2) 2000 years of the Church's Universal Magisterium (prior to V2) all lies.

Because it would go contrary to the NO narrative, point #2 is always non-existent in this novus ordo doctrine.  
   

Your poll choices demonstrate that you not only know nothing about the OUM and what it actually is, but also that you lack any understanding of the current crisis.  You believe that the mere existence of the OUM is all that matters, even if it has defected from teaching truth.

So who comprises the OUM of the Church according to you?

Do you mean who exercises the OUM?

That is clearly defined by Vatican I.  Pope and the bishops teaching unanimously in union with him, when they teach something as being de fide, cannot err.

Even the Wikipedia the Jєω-Encyclopedia is honest enough as to recognise the second requirement, and yet most Novus Ordites aren't. However, the Magisterium refers not only to the Church's ancient teachings but also to the teaching authority of the Church and those who have it. That being the hierarchy of the Church, whom the indefectibility promise also applies to. If almost the entirety of the Church's hierarchy, including the Pope, teach heresy for decades - is that not defection? Xavier's question still stands, where is the legitimate teaching body of the Church? Does it rest in the hands of Pope Francis and his Liberal goons? Bishops in the SSPX, or the Thuc line, or... etc.

Absolutely.  Some seem to think that the mere existence of the Church and the Magisterium are all that's required for indefectibility.  But the Church cannot defect in her MISSION either.

Catholic Encyclopedia:

Among the prerogatives conferred on His Church by Christ is the gift of indefectibility. By this term is signified, not merely that the Church will persist to the end of time, but further, that it will preserve unimpaired its essential characteristics. The Church can never undergo any constitutional change which will make it, as a social organism, something different from what it was originally. It can never become corrupt in faith or in morals; nor can it ever lose the Apostolic hierarchy, or the sacraments through which Christ communicates grace to men.

So the R&R emphasize "merely that the Church will persist to the end of time", while SVs emphasize that it can "never become corrupt in faith or in morals".

What XavierSem is bungling through attempting to articulate is to ask whether any organs of the Magisterium continue to exist today.

Where do you get the idea that the hierarchy is indefectible? Do you believe they're infallible too? If not, then how is a fallible hierarchy able to be indefectible?

From: Who Shall Ascend?

...Contrary to such reasoning, it is within the Conciliar Establishment that one finds the historical and structural continuity of the True Church; even though they are serving Satan, those who hold ecclesiastical offices hold them legitimately. Those who say otherwise have not proved that, because these men are apostates from the Faith, they cannot be considered to hold any offices.

"One who is no longer a Catholic," they say, "cannot possibly hold an office within the Church, nor exercise legitimate authority." No, even though these individuals have incurred the censures of the Church's law for heresy, apostasy, the desecration of the churches, the violation of the Sacraments, for these and similar crimes, they continue to be the legitimate
authorities of the Church. And since they do hold these offices, others who seek to interpose themselves into authority over the Catholic faithful, commit schismatical acts in doing so, and themselves incur the penalties of the Code. - Fr. Wathen, Who Shall Ascend?
