Agreement on some matters (like the deity of the Son) does not require agreement on others (like Purgatory) as a matter of logical consistency. A slate of doctrinal pronouncements trumpeted by Rome can be accepted in part and rejected in part without sacrifice of logic. I am free to accept A, B and C while rejecting X, Y, and Z (particularly if X is the doctrine of papal infallibility when speaking ex cathedra).
You miss the point. The CC got it right about the Trinity, (A,B,C) but has no authority for X,Y,Z. I don't see that as logical.
It is worth emphasizing that Nicaea and Chalcedon were not "Vatican" councils in any sense. (Of the 300-odd bishops attending at Nicaea, I think only four were from the West, including a couple sent by Pope Sylvester.) They were ecumenical or "catholic" in the broader sense, without recognition of Roman primacy.
It's worth emphasizing that it is impossible to hold a council without Roman primacy.
"Divinity or Godhood of Christ" was declared at Nicaea and Chalcedon, while "Church government, the Eucharist, Mary, Purgatory" were not (well, there actually was a pronouncement on Church Government at Nicaea, in
Canon #6 -- and it does not support recognition of Rome's world-wide authority).
We've already been over this. There is no indication of Protestantism at Nicae that you are trying to Protestantize.
The Council of Nicea was Catholic
"But wait," a Protestant might respond. "What about Canon 6 of the Council of Nicea? Doesn't that demonstrate there was no papal primacy in the early centuries of the Church?"
This claim is always presented in polemical discussions of the Nicene Council.
The PlayersMajor Figures at the First Council of Nicea (A.D. 325) Arius, a popular Alexandrian priest who, under the influence of Lucian of Antioch, denied the divinity of Christ. According to Arius, Jesus was the first "creation" of God, but was not God Himself. This false teaching was rebuked at a local Egyptian synod of bishops, but Arius refused to submit to their correction and was excommunicated. After several appeals, his heretical views were aired, debated and formally condemned by the bishops of the Catholic Church assembled at Nicea.
St. Athanasius, a priest from Alexandria (who would become the bishop in 328) and tireless defender of the Trinity and Catholicism. Along with Bishop Alexander of Alexandria and Bishop Hosius of Cordoba, he stood as Arius' chief and most formidable opponent.
Hosius, Bishop of Cordoba, and presider over the Council. He played a central role in Constantine's conversion, and acted as the Emperor's theological advisor. A vocal opponent of Arius, Hosius represented the Church of Rome, along with two Roman priests.
Vito and VincentiusThe two Roman priests sent by Pope Sylvester (who was too sick to travel) to represent the Church of Rome at the Council of Nicea. They, along with Bishop Hosius, signed the acts of the Council before the other convened bishops did —
which was a remarkable thing for mere priests to do, unless they had special authority as legates of the pope.
