It appears like you’re agreeing that papal infallibility wasn’t a doctrine of your Church before
1870. That’s interesting.
It certainly wasn’t an official doctrine of the Church before then. But you already knew that,and so do Catholics,so why do you find it “interesting”?
So, papal infallibility was an immemorial teaching of your Church before I asked the hard question of why nobody who condemned it was silenced as a heretic.
I never said it was always an official teaching of the Church. Neither,for that matter,was the doctrine of the Trinity an official teaching before the Council of Nicaea.
However, when you couldn’t answer this question it becomes just another “belief of theologians” that later became a doctrine. It must be very convienent to shift positions like this, but it really ruins your credibility and that of your Church when you do so.
Also, if papal infallibility was just an opinion before 1870, why are Orthodox Christians condemned for denying it?
If the Orthodox are to be condemned,it is due to the denial of other doctrines coming from the See of Peter. If,for example,the procession of the Holy Spirit from the Father and Son is contradicted,then it logically follows that papal infallibility on matters of faith is being contradicted as well. To believe in the one doctrine is to be ready to believe in the other,and to reject the one is to be ready to reject the other. It is not papal infallibility by itself which is accepted or rejected,but also other doctrines,including the most essential ones,that papal infallibility confirms. If Peter is not trusted when he teaches,then everything he teaches is open to contradiction,including the most essential teachings of the faith.
According to your logic, we left the Church while this teaching was just an opinion. You turn the Great Schism into one of bad timing, which is absurd.
The schism was over the filioque controversy.
By rejecting the filioque,the Eastern clergy simultaneously rejected the teaching authority of the pope,which they had upheld as unquestionable until that time.
Besides, this whole idea of opinions evolving into doctrines cannot be defended anywhere in the Tradition of the Church. The Deposit of Faith is always taught and believed as the teaching of Christ. The Faith was given in doctrinal form to the saints “once for all” (Jude 3) and the holy martyrs died for the same Faith I profess today, not for a mixture of doctrine and opinions that will later become doctrine.
If that were true,then what was the need for the councils of Nicaea,Constantinople,and Chalcedon? What was the need for the Cappadocian fathers to go to such lengths in defining the Trinity and other aspects of the faith? For an Orthodox to believe that everything in the deposit of faith was given as doctrine once for all is as wrong-headed as a Protestant believing that men are saved once for all.
