Great examples. What strikes me is that development of doctrine (the way it was explained by Fr. Hopko and the way it makes sense to me) happens organically and is sort only made official when the issue is forced (hence the councils).
The few Catholics that I've talked to about stuff like this have no problem with the Orthodox explanation as opposed to the traditional Roman terminology. I personally find Orthodox way of describing these things to make more sense, but then again that's just my personal opinion on how I came to learn and accept certain things. Maybe it has to do with Roman teaching being a direct response to Protestantism on western terms, where Orthodoxy doesn't have that same immediate historical necessity.
However, the so called Catholic doctrines which Orthodox disagree with seem to have defined without any great need.
I find it puzzling why the only two real known "ex cathedra" statements both came after the definition claiming the Pope always had that authority, and were not based in any real controversy that required a formal definition.
I think the papal dogmas devoloped out of a specific situation particular to a specific time and place under specific conditions (which can only exist in schism with Orthodoxy). Not supporting them, only saying that I can see how they came about and the necessity of the Pope in europe in the middle ages as a center of unity for the west and in isolation of the east.
Everything else that really matters, I think stems from defining points with unnecessary precision (time in purgatory, literal fire, strict use of legal terminology, inserting additions to the creed, etc). I just read a book on the Council of Florence and St Mark's original opposition to the filioque, was simply that the creed was universally decided to remain unchanged and no one bishop had the authority to override that. He used the Council of Ephesus as an example where the council dogmatically defended the use of the term "Theotokos", but refused to insert it into the creed even though it would have been doctrinally sound and was being used to combat heresy at the time.
