in 1870 when Pius decided he wanted to be infallible and split the church, OH, so that's when this heresy entered in.
Yes, that is when Rome officially foisted it on the church as a mandatory belief.
It appears to be the creation of Peter Olivi, a Franciscan who was more than once accused of heresy (an auspicious parent for the concept of infallibility, wouldn’t you say?). His reason for attempting to limit papal power seems to have been to prevent future popes from rescinding a ruling favorable to Franciscans made by Pope Nicholas III (1277-1280).
Nicholas was willing to go along with this idea, but later popes rejected it outright. For example, Pope John XXII (1316-1334) went so far as to call it “…a work of the devil…the Father of Lies.” and in 1324 actually issued a papal bull condemning it as heresy.
Pope John XXII declares papal infallibility "a work of the devil..the Father of Lies". Pope Pius IX declares it a dogma in 1870.
Another intersting tidbit of history. The bull Dominus ac Redemptor Noster of Pope Clement XIV, On July 21, 1773, "infalliblly" banned the Jesuit order by a perpetual decree never to be rescinded
The banished Spanish Jesuits ended up on the island of Corsica. In 1801, Pope Pius VII signed a Concordat with Napoleon Bonaparte and crowned him Emperor of France in 1804.
On Sunday, the 7th of August 1814 Pope Pius VII removed the perpetual ban of his predecessor, (offcourse, infallibly)!!
“banned the Jesuit order by a perpetual decree never to be rescinded”
Now that is a papal decree that I can wholeheartedly endorse. The world would be a better place if it would never have been lifted.
Talk about a diabolically misnamed entity ... the Society of Jesus.
