Unfortunately you are confusing two distinct issue here: accepting the authority of a council vs. understanding the teachings of a council. Even today, 50 years after the 2nd Vatican Council, the Catholic Church as a whole is only now truly beginning to digest all the teachings of the council and actually implement them properly. This has been the case with all councils, but this does not mean in any way that immediately following a council that the Church does not accept the council’s teachings as infallible. Many attending members of Vatican II, like Benedict XVI, have understood the council’s teachings all along, but it has taken a life of writing and teachings from him and others like him for the teachings of the council to be fully understood within the Church. The same can be said for Nicaea and the rest of the councils in between.
This is NOT the same thing as the outright rejection of a council like what occurred in Orthodoxy after Florence,
This is a distinction without meaning, because if one rejects the authority of a council, he also of necessity rejects that the council possessed the authority to expound upon the faith, and therefore rejects the faith of the Council. But even if we were to grant this distinction, there still exist plenty of examples throughout history of people having not only rejected the authority of a council, but having rejected its faith outright. The Conciliarists (who were instrumental in ending the Great Western Schism) in fact went into schism in the aftermath of Florence, refusing to accept any of its teachings on the supremacy of the papacy.
Then there were the Franks, who rejected not only the authority of the Seventh Ecumenical Council, but its central teaching and tenet that it is proper and right to offer unto icons worship of veneration. They did not do so, as is commonly said in apology of their intransigence, out of ignorance of what the council taught, but rather what they affirmed in their own synods shows that they did not consider it proper to offer unto images the worship of veneration.
There were also the numerous sees of Northern Italy and Spain which refused to accept the Fifth Ecumenical Council’s teachings, on the grounds that they were a betrayal of the council of Chalcedon.
Also of note is that Florence occurred before the splintering of Orthodoxy into regional Churches, so the Patriarch of Constantinople had more real-world authority than his successor does today.
Makes for a nice story, but in reality, Christianity in both the East and the West has always operated along the lines of regional synods, which is why other patriarchs and archbishops of the East had delegations present, which acted independently from the small group of bishops (barely two dozen), who represented the synod of Constantinople. Some delegations, like the delegation of the Georgian Catholicos left without ever signing (the Georgians in fact never approved of Florence).
especially considering that the Othodox Patriarch and bishops who accepted the council’s teachings were never considered un-orthodox or ousted as heretics in their post-council lifetimes.
False. Upon returning home, those bishops who signed found themselves ostracized by the clergy who remained in Constantinople, to the point that they even refused to officiate with them. Furthermore, many returning bishops immediately repudiated the council. Bishop Anthony of Heraclea even recanted in a most dramatic fashion, claiming that he signed involuntarily, and that he should give himself up to judgment for betraying the faith. Even the Emperor, who was customarily commemorated in the petitions during the liturgy, had his name omitted in many churches throughout the city. The Union in fact, was only upheld by the emperor’s ability to confirm episcopal elections as sovereign of Constantinople.
The Three other Eastern Patriarchs (not personally present at the council), Dorotheos of Antioch, Philotheos of Alexandria, and Joachim of Jerusalem did not approve of the council, calling it among other things, the “lawless Council of Florence,” and even going so far as to declare in 1443 all of those ordained by the pro-union Patriarch Metrophanes of Constantinople were deprived of all ecclesiastical degrees and of any rights of officiating, for the reason that they had partaken in the pro-union heresy of Metrophanes, until their faith could be investigated by an ecumenical council (so much for the claim that pro-union patriarchs were never considered unorthodox, the three Patriarchs of the East would not even recognize any clergy ordained by the first such pro-union patriarch).
