As a Catholic I take offense to the direction that this thread has taken. The list of heresies that seeks to show, as I read it, that the East has always been the problem child of the Church and unable to stay on the path of right doctrine. This is A) absurd and B), if I have read the intention correctly, in poor taste. The presence of more heresies in the East than West - if indeed there are more - was due to the fact that in the time in question, in general, there was more education (specifically Classical) available in the East than in the West {for example - the Academy was open until Justinian closed it I believe}, and with that more speculative thinking was present leading both to the development of heterodoxy and the orthodox responses to it. This is not really a bad thing.
Moving on…
The filioque was NOT an excuse for anyone to break away form anything. I am too tired to go into any details. This is an inaccurate statement which will never help to engender unity of communion!
BTW the list of heresies is a poor polemical tool that purposely seeks to distort history in favor of a skewed view of the Church. There have been plenty of heresies in the West, another poster noted the rise of Protestantism.
Also suggesting, as a blanket statement, that the Holy Patriarchs of the East were all power hungry is not a good apologetic tool, etc. They were are all human yes, but not all power seekers, so why pick about being human.
Side Point: Even if you hold to Papal Supremacy and Papal Infallibility, you must acknowledge the humanity of each man who is Pope. Being Pope does not come with some sort of supernatural perfection in EVERY THING that you do as Pope. Infallibility - as it has been defined - is very limited!!!
God Bless,

I am tired, so I will return when I am fresher in mind.
