i agree there was a central authority in the pope that is undenibale that is called papal primacy
but papal primacy is not papal supremacy .
and like i mentioned papal supremacy is the only argument that protestans can say is a later addition made by the catholic church since the evidence for it being so is so overwheliming that even some catholics historians and theologians agree
and the evidence against it is few and not really solid poting to the canon is not an example of papal supremacy as the canon where dictated by councils, and the pope only recognized them . again this not papal supremacy but primacy
example this
The Council was presided over by Eutychius, Patriarch of Constantinople, assisted by the other three eastern patriarchs or their representatives. Pope Vigilius was also invited; but even though he was at this period resident in Constantinople , he declined to attend, and even issued a document forbidding the council from preceding without him (his ‘First Constitutum’).
The council, however, proceeded without the pope to condemn the Three Chapters. And during the seventh session of the council, **the bishops had Vigilius stricken from the diptychs for his refusal to appear at the council and approve its proceedings, effectively excommunicating him personally .
Vigilius was then imprisoned in Constantinople by the emperor and his advisors were exiled. After six months, in December 553, he agreed, however, to condemn the Three Chapters, claiming that his hesitation was due to being misled by his advisors.
if papal supremacy existed this event would have not happend or gone the way it did and not so against the pope
or in some cases councils against the pope (see fourth Ecumenical Council)
, same with the filioque, beacuse if papal supreamcy was there since the begining and the orthdox church would have not split since the main reason of the split was the pope abusing his authority
however some protestans use this to show all catholic traditions are latter aditions that evolved over time
and no that is just a hasty generelaziation fallacy.
again iam not saying the pope had no power i just said papal supremacy did not exist (not the way we know it today) and what they had is papal primacy , the evidence is there .
