III. Appendix strengthened by interpretation.
Relatio of Vatican I.
Gasser: “This prerogative granted to Saint Peter by the Lord Jesus Christ was supposed to pass to all Peter’s successors because the chair of Peter is the center of unity in the Church. But if the Pontiff should fall into an error of faith, the Church would dissolve, deprived of the bond of unity. The Bishop of Meaux [French Bishop Auguste Allou] speaks very well on this point, saying: ‘If this Roman See could fall and be no longer the See of truth but of error and pestilence, then the Catholic Church herself would not have the bond of a society and would be schismatic and scattered — which in fact is impossible.’
Gasser: “As far as the doctrine set forth in the Draft goes, the Deputation is unjustly accused of wanting to raise an extreme opinion, viz., that of Albert Pighius, to the dignity of a dogma. For the opinion of Albert Pighius, which Bellarmine indeed calls pious and probable, was that the Pope, as an individual person or a private teacher, was able to err from a type of ignorance but was never able to fall into heresy or teach heresy. To say nothing of the other points, let me say that this is clear from the very words of Bellarmine, both in the citation made by the reverend speaker and also from Bellarmine himself who, in book 4, chapter 6, pronounces on the opinion of Pighius in the following words: ‘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.’ From this, it appears that the doctrine in the proposed chapter is not that of Albert Pighius or the extreme opinion of any school, but rather that it is one and the same which Bellarmine teaches in the place cited by the reverend speaker and which Bellarmine adduces in the fourth place and calls most certain and assured, or rather, correcting himself, the most common and certain opinion.”
