I very much agree with Fabio Leite, I think we all appreciate his wisdom on this subject which not all of us have had the time to understand in detail.
I read two of Francis Dvorniks books which were recommended by Fr. Theodore Pulchini and felt they were accurately portraying the once united Orthodox position.
There is enough clarity that an Orthodox Pope of Rome could become a reality if their was an agreement able to be found to "restore" (is that the correct word?) his see.
As a former life long Roman catholic, I studied the historical role of the Pope of Rome.
What fabio says sounds to me to be exactly what I understood the role to have been before the second millenium.
It is not as difficult as it sounds.
To this day I am not even bothered with the concept of infallibility of the Pope (shocking?),
though I think it a strange political decision to have made it a dogma around 1866, that did not quite make sense to me. S
Something like infallibility, if it is real should be self evident and would than not need a dogma, as it would be commonly realized.
If infallibility were actually really limited to a few very rare instances it would be of no great concern.
However, at this very time, many roman catholics think the Pope is infallible nearly all the time !
For example this was stated by a respected roman catholic on another forum:
"When a pope says that something is error free, he is exercising the Ordinary Magisterium. The Ordinary Magisterium is always infallible. The pope need not speak Ex Cathedra to speak infallibly on matters of faith and morals.
Meanwhile, lets take a quick look at this; the ordinary and universal Episcopal magisterium is infallible as it relates to a teaching concerning a matter of faith and morals that all the Bishops of the Church (including the pope) universally hold as needing to be accepted by all the faithful. It should be noted that this aspect of infallibility only applies to teachings about faith and morals as opposed to customs and prudential practices.
Every reputable link seems to indicate the Ordinary Magisterium enjoys infallibility when it comes to preaching/teaching existing doctrine. That means that the Pope, who is a bishop, can do so as well. And when he does it, he doesn't need to use Ex Cathdra, because he's using his powers as a bishop. "
Other respected roman catholics belief the statement is an exaggeration and heretical view of papal infallibility, but it is a very commonly held view, even by many of their clerics.
Don't think though, that this means I support papal infallibility of an Orthodox Pope, I really don't care either way.
I think it is a political word, and has often used to promote evil authoritarian/centralizing practices that have helped wound and harm the roman church communion.
