Forward to today.
As far as I know the EO does not have a unity among the 5 Churches. I don't seem to see a unit of one teaching.
We have many more than five Patriarchates and local churches, as referred to above, and our unity is perfectly strong as Roman Catholics have their own divides. Look at the hyper-liberal synod in France recently.
As follows seems to be "stuff that shows the Pope was always Vatican-I in his powers" which actually does not address the question of this thread, schism. No one denies that a man, as father and husband, is the head of his household. Yet, if that man absconds and deserts the family, is the man in isolation with his new women and new children (metaphors for heretical doctrines and new bishops he is in communion with) the family though he went ahead and split from the original family? Any normal person would identify the family is intact under the original wife and kids, and the ex husband is wayward and in fact, in a real sense "out" of the family. He is an ex.
Historically, the above example, as shown in the video, appears to actually play out. So, whether the Pope has vatican-i powers or not (though we think he does not) is actually irrelevant to the question.
As far as Honorius goes.
Honorius replied by referring to the
Council of Chalcedon’s
confession of faith (451), which held that Christ’s
natures were indivisible and which he
interpreted as meaning a single will in Christ.
Which the sixth council denounced as heresy. Ironically, in the 8th RC ecumenical council (Orthodox recognize the legitimate council of Constantinople that occurred 10 years later), Pope Adrian II stated: "For even though Honorius was anathematized after death by the easterners, it should be known that he had been accused of heresy, which is the only offense that inferiors have the right to resist the initiatives of their superior or are free to reject their false opinions." Pope Adrian II not only accepts that Honorius was a heretic, but he recognizes that Popes *can* be heretics, and there is complete freedom in rejecting the opinions and machinations of these heretics.
So, while I'd be sympathetic to a reinterpretation of Honorius based on good grounds, I just see it as a no go for both of us. To re-evaluate Honorius requires the Orthodox (and you) to reject the conclusion of the sixth council. For you, it requires you to reject the ex cathedra statement of a Pope to one of your own ecumenical councils. Maybe, Protestant scholars can see this as an open question, but it should be settled for both of us.
A lot of your reply appears copy and pasted when I throw it into google by the way.
You ask:
SO why is that so upsetting to all Churches and why did they finally find comfort in Rome's Pope Agatho to make the final conclusion??
Pope Agatho's letter was near the beginning of the 6th council. Later sessions as well as the decree of the council and the Pope who received the council, and later Popes, and canon 1 of Trullo, and the Council of Nicea II, all condemned Honorius.
