You are like a reprobate liberal who still insists Palin said she sees Russia from her house. I already wrote you in a previous post that Church doctrines are operational long before they are explicitly defined:"Just about all Catholic doctrine is implicit in her sacraments, such as the mass, baptism, confession, marriage, and consecration of priests, or in the Church hierarchical structure. The sacraments and hierarchy was set by the Apostles. Other than by Scripture, the Church does not define doctrine explicitly unless it is necessary to counter an heresy. Explicitly defined teachings are always based upon implicit teachings that have existed for many years or since the beginning of the Church. Petrine infallibility has been operational since it was established by Christ and exercised by Peter's early successors."
You never disputed this point. I can understand that you do not accept the doctrine of infallibility, but it makes no sense for you to mindlessly repeat the falsehood that Catholics themselves did not believe this doctrine prior to 1870.
Maybe I wasnt clear, i never said no one believed until 1870. It was only officially put on the backs of the faithfull as required belief in 1870.
Certainly, it was believed by some(not universal) before 1870 as noted by Pope John XXII (1316-1334) who issued a papal bull condemning it as heresy.
The Jesuits convinced Pius IX to steam roll it thru the first Vatican council (likely a response to losing temporal authority), causing many non Italians to break with the church.
I cannot find a bull from John XXII condemning papal infallibility as heresy. Can you provide a citation?
