In the impossible situation where that which Griff Ruby says would be true, namely, that the ecclesiastical hierarchy, collectively speaking, would persist in a group of irregularly consecrated bishops, the conclusion that would follow from such an (I repeat, impossible) situation, would be that Victor von Pentz could be accepted as a true Pope, which is as absurd as the thesis which Mr. Ruby has already set forth.
The doctrine of the Church teaches us that, since the Church is a perfect society, she always possesses the right and the power in herself to designate to herself a visible head. Thus, the theologians have written that, in the hypothesis of a situation where there would be no more certain Cardinals (if that is possible; I personally do not believe that the ordinary ways of electing the Pope can be destroyed), natural law would demand that the right to elect the Pope would devolve upon the universal Church (which would necessarily have to include Roman clergy, of course, since the Pope is the Bishop of Rome and the Roman Church can never fall into disheritance).
Now, this means that in Mr. Ruby's imagined situation, the possibility of which is in itself heretical to assert, the right to elect the Pope would, through natural law, devolve upon the irregular bishops whom he claims to be the ecclesiastical hierarchy. Since the people who 'elected' Victor von Pentz in Assisi, sent invitations throughout the whole world (even to the four men consecrated by Archbishop Lefebvre), the ones who have answered to that invitation positively by coming to their 'public conclave', would have had the right to legitimately elect the Supreme Pontiff, and by consequence, Victor would have been the true Pope. Also, the ones who had refused to elect such a pope would have been guilty of schism.
This is what this heresy leads to folks; into the anti-papal embrace of 'Linus II'.
