Little by little it seems that Archbishop Viganò is heading in the right direction. Though he still thinks Bergoglio was validly elected, he now declares him an arch heretic. So he has moved from the hoodwinkined and submissive to Bergoglio camp, to the camp of the Sediprivationists, who hold that a man can be pope but lose the authority of a pope. — A theological non sequitur, because it presupposes that two contraries are true at the same time of the same person, which is illogical.
Here is the citation of the comments of the Archbishop:
Our obedience has nothing to do with either fearful servility or with insubordination; on the contrary, it permits us to suspend any judgment on who is or is not Pope, continuing to conduct ourselves as good Catholics even if the Pope derides us, despises us, or excommunicates us: because the paradox does not lie in the disobedience of the good against the authority of the Pope, but rather in the absurdity of having to disobey a person who is simultaneously Pope and heresiarch, Athanasius and Arius, one who is de iure light but de facto darkness.
The paradox is that in order to remain in Communion with the Apostolic See we must separate ourselves from the one who should represent it, and see ourselves bureaucratically excommunicated by one who is an objective state of schism with himself
