[OLD REGGIE]

There is a misconception amongst many anti-Catholics that Papal infallibility is unlimited and unconstrained. Nothing could be further from the truth.

The infallible teachings of the Pope must be based on, or at least not contradict, Sacred Tradition or Sacred Scripture. Papal infallibility does not imply that the Pope is impeccable, or that he is exempt from liability to sin or that he is never personally wrong about dogma. It is possible that a Pope may have advocated for or taught a heretical position.

Papal Infallibility was defined dogmatically in the First Vatican Council of 1870 and has only been invoked once.

Trash! There is no such thing as a list of "Infallible" Papal Declarations.

"Trash! There is no such thing as a list of "Infallible" Papal Declarations."

Of course there isn't, but every Papal Declaration can be judged against the criteria necessary for it to be deemed infallible. When this is done there has been only one instance; in 1950 when Pope Pius XII defined the Assumption of Mary as being an article of faith for Roman Catholics. Prior to the solemn definition of 1870, Pope Pius IX, with the support of the overwhelming majority of Roman Catholic bishops, had proclaimed the Immaculate Conception of Mary an ex cathedra dogma in December 1854.
