A buddy got some info from Mary Ann Collins (an anti-catholic) and I have no idea how where to get info explaining (or debunking) it. Help!
Here’s the quote he sent me:
*The claim for papal infallibility does not stand up to the test of history. Pope Zosimus (417-418 A.D.) reversed the pronouncement of a previous pope. He also retracted a doctrinal pronouncement that he himself had previously made. Pope Honorious was condemned as a heretic by the Sixth Ecumenical Council (680-681 A.D.). (This means that Honorious made doctrinal statements which are contrary to the Roman Catholic faith.) He was also condemned as a heretic by Pope Leo II, as well as by every other pope until the eleventh century. So here we have “infallible” popes condemning another “infallible” pope as a heretic. In 1870, the First Vatican Council abolished “infallible” papal decrees and the decrees of two “infallible” councils.
The doctrine of the Assumption of Mary was officially declared to be a dogma of the Roman Catholic faith on November 1, 1950. This means that every Roman Catholic is required to believe this doctrine without questioning it. However, as we will see, the teaching of the Assumption of Mary originated with heretical writings which were officially condemned by the early Church.
In 495 A.D., Pope Gelasius issued a decree which rejected this teaching as heresy and its proponents as heretics. In the sixth century, Pope Hormisdas also condemned as heretics those authors who taught the doctrine of the Assumption of Mary. Here we have “infallible” popes declaring a doctrine to be a heresy. Then on November 1, 1950, we have Pope Pius XII (another “infallible” pope) declaring the same doctrine to be official Roman Catholic doctrine, which all Catholics are required to believe. [Note 3]
So before November 1, 1950, any Catholic who believed in the Assumption of Mary was a heretic (because of “infallible” declarations of popes).
But after November 1, 1950, any Catholic who failed to believe in the Assumption of Mary was a heretic (because of the "infallible"
declaration of Pope Pius XII).*
That’s over my head and way beyond my ability to explain. And now I’m frustrated because I look like the ignorant Catholic. Sigh.
