I find it best to stick to sites people approve of then they can’t use excuses like yours. Not that I don’t look at anti catholic sites, I do. With regard to the papal bull - NOT GUILTY in that respect. This is a catholic site. If you want to know what papal bulls etc are the links are at the top.
papalencyclicals.net/Ben12/B12bdeus.html. You could have checked this out for yourself as I have provided the link at least once before. Why didn’t you do so before accusing me of obtaining the bull from an anti catholic site?
These are the criteria for speaking ex cathedra from Vatican Council I
we teach and define as a divinely revealed dogma that
when the Roman pontiff speaks EX CATHEDRA,
that is, when,
in the exercise of his office as shepherd and teacher of all Christians,
in virtue of his supreme apostolic authority,
he defines a doctrine concerning faith or morals to be held by the whole church,
he possesses,
by the divine assistance promised to him in blessed Peter,
that infallibility which the divine Redeemer willed his church to enjoy in defining doctrine concerning faith or morals.
**Therefore, such definitions of the Roman pontiff are of themselves, and not by the consent of the church, irreformable. **

If you check this against the papal bull I think you will find that it easily meets the criteria of ex cathedra. Anybody can check this for themselves. You don’t need superb insight.
