That the Church does not function without counciliarity, neither in unity, nor in resistance...Defying it is rebellion against the Church.
You have also said that the Church tolerated the Filioque heresy, and every other heresy, and you conclude above by saying the Church does not function without counciliarity.
I must say simply - it has always been anything but.
This is just shameless and cunning, and it is intolerable that you would think to lead people without having any semblance of the truth. The Church tolerated the errors?! One cannot believe what one reads!
The Church never tolerated heresy for any space of time, but struck at its source as soon as it reared its horrible head.
Indeed, it is known that the seeds of the Filioque heresy in Augustine, the great teacher of the Westerners. Already during the fourth and fifth centuries, Latin theologians discussed this tenet. The Filioque first appeared in Spain at the Councils of Toledo in 547 and 589. Although it sprang from Orthodox motives, it was a rationalistic extrapolation which appeared during the theological battle against another heresy. From Spain, the Filioque found its way into the local confessions of the Frankish nation a little after 767.
It was not widely known and never had any official definition until it was in the hands of Charlemagne's "theologians". At this time, as soon as it was heard in Jerusalem by the Eastern Church, it immediatley caused eastern bishops to break communion with the Latins and caused a great stir. The Eastern bishops brought the heresy to the attention of the Western bishops at which time the Pope summarily rejected the addition and, in the Church of Saint Peter, placed two silver plaques which had the Symbol of Faith inscribed in Greek and Latin without the Filioque.
This heresy was put to rest until it turned up again by Pope Nicholas I. Immediatley, again, the Church reacted and those who understood the heresy condemned it before any council was convoked. This is why St. Photius was exiled.
Again we see the same happen with the Nesorian heresy. When Saint Hypatius understood what opinions Nestorius held, immediately, in the Church of the Apostles, he erased his name from the diptychs, so that it should no longer be pronounced at the Oblation. This was before Nestorius' condemnation by the Third Ecumenical Council.
When the most pious Bishop Eulalius learned of this, he was anxious about the outcome of the affair. And seeing that it had been noised abroad, Nestorius also ordered him to reprimand Hypatius. For Nestorius was still powerful in the city. Bishop Eulalius spoke thus to Hypatius: "Why have you erased his name without understanding what the consequences would be?" Saint Hypatius replied: "From the time that I learned that he said unrighteous things about the Lord, I have no longer been in communion with him and I do not commemorate his name; for he is not a bishop." Then the bishop, in anger, said: "Be off with you!
Make amends for what you have done, for I shall take measures against you." Saint Hypatius replied: "Do as you wish. As for me, I have decided to suffer anything, and it is with this in mind that I have done this." From the Life of Saint Hypatius.
So when the Orthodox priests of Constantinople ceased to commemorate
their bishop, Nestorius, they did not await the judgment of a council. And fortunately so. A council was indeed convoked in Constantinople.
What, however, was its judgment? It justified Nestorius and anathematized the Orthodox!
And the same thing happened at the time of the Iconoclasts. Orthodox Christians broke communion with the Iconoclasts and did not wait for a council. But a "Ecumenical Council" was finally convoked in 754, and what did it say? It condemned the Orthodox, again! Fortunatley, the Orthodox did not think as you do.
