Let's say that the Pope met with an Orthodox Patriarch and officially recanted the RC doctrines of the Papacy, Immaculate Conception, the Filioque and all other doctrines which the Orthodox consider to be heresy, and wanted the Roman Catholic Church to officially rejoin the Orthodox Church.
What would happen?
Especially, how would this affect the whole North American jurisdiction situation? Technically, since America is in the west, and since the Pope would probably reclaim his first-among-equals title from Constantinople, wouldn't North America become the Pope's territory? I imagine that the more convertsky jurisdictions like the OCA and Antiochians would jump at the opportunity of falling under the Pope's jurisdiction, since it would give us more of that unity we've been craving for so long. On the other hand, I imagine that the more immigrant Churches--such as the Greeks, wouldn't like it one bit, and would possibly become schismatic. I also imagine that the current Ecumenical Patriarch wouldn't like it because he'd lose his Ecumenical status, and possibly lose his control over North America.
