Does the Pope live a life which is unblemished with no branding if he speaks ex cathedra and is infallible?

Last Updated on February 23, 2023 by pg@petergamma.org

Papal infallibility is a dogma of the Catholic Church which states that, in virtue of the promise of Jesus to Peter, the Pope when he speaks ex cathedra is preserved from the possibility of error on doctrine “initially given to the apostolic Church and handed down in Scripture and tradition”.

No, Papal infallibility is not unblemished, it is controversial:

But who needs the Papal infallibility? Is the infallibility from Jesus? And if not, can it be abolished, and by whom? The Catholic Church is not a Swiss democracy.
