What heresies did the pope save the east from? The east called and held the first seven councils, none of which was attended by the pope.

These historical facts may be briefly summarized as follows: All three of the great Eastern sees were under the jurisdiction of heretical patriarchs simultaneously during five different periods: 357-60 (Arian), 475-77, 482-96, and 512-17 (all Monophysite), and 640-42 (Monothelite): a total of 26 years, or 9% of the time from 357 to 642.
At least two out of three of the sees suffered under the yoke of a heterodox “shepherd” simultaneously for 112 years, or 33% of the period from 341 to 681 (or, two-thirds heretical for one-third of the time), and at least 248 of these same years saw one or more of the sees burdened with sub-orthodox ecclesiastical leaders: an astonishing 73% rate.
Thus the East, as represented by its three greatest bishops, was at least one-third heretical for nearly three-quarters of the time over a 340-year span. If we examine each city separately, we find, for example, that between 475 and 675, the patriarchs of Constantinople, Alexandria, and Antioch were outside the Catholic orthodox faith for 41%, 55%, and 58% of the time respectively.
Furthermore, these deplorable conditions often manifested themselves for long, unbroken terms: Antioch and Alexandria were Monophysite for 49 and 63 straight years (542-91 and 475-538 respectively), while Constantinople, the seat of the Byzantine Empire and the “New Rome,” was embroiled in the Monothelite heresy for 54 consecutive years (610-64). There were at least (the list is not exhaustive) 41 heretical Patriarchs of these sees between 260 and 711.
Roman Steadfastness
No such scandal occurred in Rome, where, as we have seen, heresy was vigilantly attacked by the popes and local Synods, and never took hold of the papacy (not even in the ubiquitous “hard cases” of Honorius, Vigilius, and Liberius - none having defined heretical doctrines infallibly for the entire Church to believe). Rome never succumbed to heresy. It experienced barbarian invasions, periodic moral decadence, a few weak or decadent popes, the Protestant Revolt, the “Enlightenment,” Modernism, etc., but always survived and rejuvenated itself. The papacy continues unabated to this day, with venerable power and prestige - the oldest continuing institution in the world. Thus, Rome has far and away the most plausible claim for apostolic faithfulness, and its history is a striking confirmation of the Catholic claims. An Orthodox position of papal primacy (not supremacy) can be synthesized fairly plausibly with these facts, but the anti-ecumenical stance assuredly cannot.
