Nevertheless, writes the author: "Some have gone so far as to call Cardinal Burke Schismatic"!!!
I wonder what they would have said about St. Robert Bellarmine, saint and Doctor of the Church, who said the following (to my knowledge, this has never been rendered into English before.[Hat tip to L.S.]
St. Robert Bellarmine makes an interesting comment in the famous chapter of De Romano Pontifice where he discusses the question of the loss of Papal office. It is in the article immediately before the one sedevacantists frequently use, namely in De Romano Pontifice, Bk II, Chapter 30:“The third opinion is on another extreme, certainly, that a Pope cannot be deposed either through secret heresy, or through manifest heresy. This recalls and refutes Bishop Turrecremata (loc cit) [Bellarmine is noting in the previous point, citing this Bishop, where he rejects that a secret heretic can be judged] and certainly is an improbable opinion. Firstly, that a heretical Pope can be judged, is expressly held in Can. Si Papa dist. 40, and with Innocent III (serm. 2 de consec. pontif.) And what is more, in the 8th Council, (act. 7) the acts of the Roman Council under Pope Hadrian are recited, and therein contained, that Pope Honorius appears to be justly anathematized, because he had been convicted of heresy, which is the only reason permitted for inferiors to judge superiors. It must be noted, that although it is probable that Honorius was not a heretic, and that Pope Hadrian II was deceived from corrupt examples of the VI Council, and Honorius was reckoned falsely to be a heretic, nevertheless we cannot deny, in fact Hadrian with the Roman Council, nay more the whole 8th general council had sensed, in the case of heresy a Roman Pontiff can be judged. Add, what would be the most miserable condition of the Church, if she would be compelled to acknowledge a manifestly prowling wolf for a shepherd.”
