Ok.
2 questions.
Is it possible for a pope to be a heretic or even apostate when elected?
1917 canon law prescribes the process for determining “pertinacity,” which is necessary before one can be canonically excommunicated for heresy.
For those suspected of heresy (
suspectus de haeresi), pertinacity is not to be assumed. Instead, “
If a person is suspected of heresy, he is to be warned. If the warning is neglected he is to be debarred from legal acts. If he remain recalcitrant for six months longer, he is to be deemed a heretic and incurs the penalty imposed on heretics” (
The Catholic Encyclopedia, 1918 edition, supplemental volume, containing revisions of the articles in canon law according to the Code).
Is it possible for a pope to become a heretic or even apostate?
No. Not according to what
St. Robert Bellarmine affirmed as the “
most common and probable opinion”, an opinion also cited in the official
relatio at the First Vatican Council.
“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.” De Romano Pontifice, book 4, chapter VI, cited by Bishop Vincent Ferrer Gasser of Brixen, in the official Relatio on the Proper Sense of the Proposed Doctrine of Papal Infallibility, prior to the vote on Pastor Aeternus (c. July 11, 1870)]
It would be rather UNtraditional to contend otherwise.
The question remains…was Cardinal Roncalli, before the election, suspected of heresy? If so, was he warned? If so, by who? When? Was that warning neglected? If so, was he then debarred from legal acts? If so, by whom? After being debarred, did Roncalli remain recalcitrant for six months? If so, did his superiors therefore deem that he was a heretic and impose the penalty incurred by heretics?
My understanding is that none of the above happened prior to Roncalli’s election. If there is credible evidence to the contrary, it has not been made manifest.
Moreover, according to Cardinal Billot:
“God may allow that a vacancy of the Apostolic See last for a while. He may also permit that some doubt be risen about the legitimacy of such or such election. However, God will never allow the whole Church to recognize as Pontiff someone who is not really and lawfully. Thus, as long as a pope is accepted by the Church, and united with her like the head is united to the body, one can no longer raise any doubt about a possible defective election… For the universal acceptance of the Church heals in the root any vitiated election."
