Zipper,
Being a Protestant, I’m going to defend the Catholics regarding Papal Infallibility: You mis-understand it’s limited meaning. And the Pope’s recent ecology letter does NOT fall into the category of being ‘infallible.”
I am copying the following from this website: http://www.catholicfaithandreason.org/papal-infallibility.html
What is the gift of infallibility?
The dogma of infallibility was formally proclaimed at the First Vatican Council in 1870. There are several requirements for a dogmatic, papal infallible pronouncement: (1) The pronouncement must be made by the lawful successor to Peter. (2) The subject matter must be in the area of faith and morals. (3) The pope must be speaking ex cathedra, that is from the very seat and office of Peter
Like maybe he should talk about stuff like slaughtering Christians and other minorities. You'd think there'd be a message from a greater source about that one.
papal infallibility means that the pope makes, or should make, no mistakes in matters concerning the doctrine of the Catholic Church. The Council even went so far as to state that should anyone, which God forbid, have the temerity to reject this definition [of papal infallibilityMP] of ours: let him be anathema [condemnedMP] (First Dogmatic..., 1870, 4.9).
For more than a century, this dogma has plagued many Catholics who have worked feverishly to try to harmonize the nature of the infallible dogma with the declarations, teachings, and revelations of the popes who lived before and after its establishment. After all, it is claimed that the Catholic Church does not create new dogmas; rather, it proposes eternal truths already contained in the deposit of faith (see Roman Catholic..., 1892, 8:772; Dixon, 1852, p. 197). Therefore, it could be said that, before the 19th century, every pope has been subject to infallibility without knowing it.
