OK… such as? (And please remember, in order to demonstrate your case, you’re going to have to address the magisterium’s claims demonstrating that it actually had been part of the belief of the Church for all time!)
I’m going to address Papal Infallibility just because I have been reading about how it developed. Keep in mind, history doesn’t tell us what didn’t happen. It only tells us what happened.
Most of what is below can be attributed to
Brian Tierney The first part is a summary that I wrote, at the bottom is a quote from his book.
If you go back to the 12th and 13th century Canon lawyers taught that “in matters of faith a general council was greater than a pope” The canon lawyers never taught the Pope was infallible.
The first recorded person to assert a doctrine of Papal Infallibility was Peter Olivi. Who was a Franciscan Monk. He lived under the fear that a future Pope would overturn the Franciscan way of life and the Papal Privileges given to Saint Bonaventure by Pope Nicholas III. Olivi wrote that the decrees of true popes “should be regarded as, not only authoritative for the present, but immutable, irreformable for all time to come”". Ironically, Olivi wanted to limit the power of future Popes by making them subject to the rulings of previous Popes. Olivi’s new theory of Papal power was ignored until 1322 when Pope John XXII actually revoked the pro-Franciscan provisions. After the Fanciscans appealed to Pope John, Pope John issued the
Bull Ad Conditorem where John said he had the right to change any decisions of his predecessors. Well the Franciscans weren’t happy and condemned the Popes Bull and denounced John XXII as a heretic for attacking their doctrine of poverty. “In this work (of the Franciscans) was the first time the ancient teaching that one of the keys conferred on Peter had been a “key of knowledge” was used to support a doctrine that the pope was personally infallible when he used this key to define truths of faith and morals”
Pope John responded with the Bull
Quia quorundam which said that the father of lies had led his enemies to maintain the erroneous thesis that “what Roman pontiffs have once defined in faith and morals with the key of knowledge stands so immutably that is not permitted to a successor to revoke it”.
“
There is no convincing evidence that papal infallibility formed any part of the theological or canonical tradition of the church before the thirteenth century; the doctrine was invented in the first place by a few dissident Franciscans because it suited their convenience to invent it; eventually, but after much initial reluctance, it was accepted by the papacy because it suited the convenience of the popes to accept it” Origins of Papal Infallibility, Brian Tierney page 274
***I noticed on his wikipedia page the following quote
“Most scholars recognize that Tierney correctly located in the late 13th and early 14th centuries the first discussions of papal infallibility” . The quote is attribute to the New Catholic Encyclopedia
