To sedes: If you truly believe Pope Ven. Pius XII was the last Pope of the Roman Catholic Church, why haven't you elected a new Pope yet? Better hurry, because time is running out. In fact, unless you are willing to change your opinion and admit that Pope John XXIII was the last Pope, it has already run out! The Bishops appointed by Pope Pius XII have died, the last one passing in July 2020. The Bishops appointed by Pope John XXIII may be alive for a short while longer.
See:
https://en.wikipedia.org/wiki/List_of_oldest_living_Catholic_bishops_and_cardinals (Sort by Consecrated Bishop Year. There appear to be about 6 left currently. Why aren't Sedes contacing these Bishops?)
Now Fr. Suarez cites as the common opinion of the Doctors, that Bishops who are Ordinary Pastors, must pass a binding declaration of fact that the See is Vacant, before a new Pope can be elected.
The Doctors only envisioned one single Pope possibly becoming a heretic, and the Bishops taking against him in his lifetime, not an alleged indefinite series of 6+Popes to whom nothing is done.
"In the first place, who ought to pronounce such a sentence? Some say that it would be the Cardinals; and the Church would be able undoubtedly to attribute to them this faculty, above all if it were thus established by the consent or determination of the Supreme Pontiffs, as was done in regard to the ɛƖɛctıon. But up to today we do not read in any place that such a judgment has been confided to them. For this reason,
one must affirm that, as such, it pertains to all the Bishops of the Church, for, being the ordinary pastors and the pillars of the Church, one must consider that such a case concerns them. And since by divine law there is no greater reason to affirm that the matter is of more interest to these bishops than to those, and since by human law nothing has been established in the matter,
one must necessarily sustain that the case refers to all, and even to the general council. That is the common opinion among the Doctors”.

Who are they? As the "last Pope" himself taught, in the "last year" of the Papacy at that, "
jurisdiction passes to bishops only through the Roman Pontiff as We admonished in the Encyclical Letter Mystici Corporis in the following words: ". . . As far as his own diocese is concerned each (bishop) feeds the flock entrusted to him as a true shepherd and rules it in the name of Christ. Yet in exercising this office they are not altogether independent but are subordinate to the lawful authority of the Roman Pontiff, although enjoying ordinary power of jurisdiction which they receive directly from the same Supreme Pontiff."[13]40. And when We later addressed to you the letter Ad Sinarum gentem, We again referred to this teaching in these words: "The power of jurisdiction which is conferred directly by divine right on the Supreme Pontiff comes to bishops by that same right, but only through the successor of Peter, to whom not only the faithful but also all bishops are bound to be constantly subject and to adhere both by the reverence of obedience and by the bond of unity."[14] http://www.vatican.va/content/pius-xii/en/encyclicals/docuмents/hf_p-xii_enc_29061958_ad-apostolorum-principis.html The sede bishops know this, and admit it, and thus acknowledge they don't have Ordinary Jurisdiction, as no Pope appointed them. Ok. But what about those appointed by real Popes?
If Pope Pius XII was the last Pope, it's game over. The required imperfect General Council, comprised of Ordinary Pastors, can never again be assembled. The Church is finished.
If Pope John XXIII was the last Pope, you have some years left. But there are only a few Bishops still alive who were appointed by H.H. Why aren't sedes reaching out to them?
Better hurry!
