Here’s the accusation by Carlo Vigano. Vigano says: “But pay careful attention: these words simply constitute the umpteenth provocation by which the “ultra-progressive” part of the Hierarchy wants to artfully provoke a schism”….
Vigano: “It appears that Bergoglio is impudently trying to “raise the stakes” in a crescendo of heretical affirmations, in such a way that it will force the healthy part of the Church – which includes bishops, clergy, and faithful – to accuse him of heresy, in order to declare that healthy part of the Church schismatic and “the enemy of the Pope.” ”
Is it possible for a Pope to teach or commit heresy? No. The First Vatican Council declared dogmatically the opinion of Bellarmine that Popes canot teach or commit heresy. This was explained to the Council fathers by the Bishop sent in a delegation from Pius IX, who explained it as the same idea “which Bellarmine adduces in the fourth place….the most common and certain opinion,” and in particular, this idea: “”It can be believed probably and piously that the supreme Pontiff is not only not able to err as Pontiff but that even as a particular person he is not able to be heretical, by pertinaciously believing something contrary to the faith.” That opinion of Bellarmine is dogma now. It was approved by Vatican I. No valid Pope can teach or commit heresy. And almost all the papal accusers say Francis is valid.
Is it possible for a Pope to provoke a schism, deliberately? No. Such an choice or intention by the Roman Pontiff would be a grave failure of faith, as apostasy, heresy, and schism are the three grave failures against the infused virtue of faith. But the Pope has the charism of never-failing faith. So neither apostasy, nor heresy, nor schism is even possible, if the Pope is valid.
However, it appears that Vigano is implying that Pope Francis is not the valid Pope. He refuses to call him “Pope”. He calls him instead “Jorge Mario Bergoglio.”
Vigano: “Jorge Mario Bergoglio is trying to force some Cardinals and Bishops to separate themselves from communion with him, obtaining as a result not his own deposition for heresy but rather the expulsion of Catholics who want to remain faithful to the perennial Magisterium of the Church. This trap would have the purpose – in the presumed intentions of Bergoglio and his “magic circle” – of consolidating his own power within a church that would only nominally be “Catholic” but in reality would be heretical and schismatic.”
Wow. These claims are severely heretical and schismatic. Vigano does not accept the authority of Francis as Pope at all. He clearly thinks Francis is an antipope, in which case it would be possible for an antipope to commit any sin. However, Francis has been accepted by the body of Bishops as Pope, therefore, he must be true Pope. For the body cannot go astray following a false head, as the Church is indefectible.
Vigano: “he who ought to be guiding the Barque of Peter has chosen to side with the Enemy, in order to sink it.”
That is not possible, as the Pope has a never failing faith. Also the Church is indefectible, and this indefectibility is obtained by grace, not by force. So the Pope is given the grace to never teach grave error and to never fail in faith, and therefore we never have a situation like the imaginary situation proposed by the papal accusers, where the Pope is trying to sink the sole Ark of Salvation. That is a fiction designed to cover the fact that the papal accusers are schismatics and heretics. The Church has taught ideas contrary to their understanding, so they have invented a conspiracy theory where the Pope is this evil character trying to destroy the Church from within — so that people won’t see that the real villains are the papal accusers.

the reproach of Christ 
Vigano lives in another world or another century.
“Jorge Mario Bergoglio is trying to force some Cardinals and Bishops to separate themselves from communion with him, obtaining as a result not his own deposition for heresy but rather the expulsion of Catholics who want to remain faithful to the perennial Magisterium of the Church. ”
Vigano and his followers don’t get it still – it is NOT ABOUT THEM. Pope Francis was elected in 2013 not to kick out ultra conservatives but to make reforms willed by the vast majority of bishops and cardinals who elected him. Pope Francis showed that he has no interest to excommunicate the ultra conservatives, despite their numerous attempts to force his hand.
And why would they want to play a “victim”? They know well they have ZERO CHANCE in the next conclave to elect cardinal Sarah or any other super conservative. Therefore they will make their own “conclave”, i.e. schismatic conclave that will elect an antipope. And they want the historic guilt for that decision to be carried by “Bergoglio and his circle”, i.e. the Universal Church.
But what does Vigano propose as alternative of the so called “Bergoglian church” of 1.3 bln? What he proposes in previous letters is nothing less than cancelling the last Church Council Vatican II. I doubt he is OK with Vatican I as well. Does he support the Council of Trent? Ron gave arguments that actually Vigano does not follow the Council of Trent. What Vigano and his group want is to return history, something impossible, and to enforce on the Catholics and humanity (by the extend of influence the Catholic Church has) archaic model that has proven to have many faults, to say the least. But if Vigano would have lived in 10th century, then he would be named heretic for less writings.
