Glory to Jesus Christ!
I respect the opinions of the first two respondents, and agree.
One point I should like to make is that if the Latinizations were reintroduced now, some Byzantine Catholics would be content because they grew up with them and have a sense of nostalgia about it. Their long gone great-grandparents had already lived through the heartbreak of seeing the traditions eroded away. Many of the younger Byzantines are all fired up over the restorations though, and we are entering a new springtime for Byzantine traditions.
As we can see Eastern Catholic churches have been the subject of that sort of abuse in the past, and it has indeed resulted in large numbers of Byzantine-rite Catholics going over to the Orthodox churches. In fact, many of the most vocal Orthodox posters you will find here or elsewhere have family histories in union with Rome, and know from which they speak.
In other words, on the part of the Orthodox we aren’t dealing with idle speculation, inordinate suspicion, a “worst case scenario” or anything like that. We are speaking of real experience of families who have lived through the sort of oppression and abuse asked about in post #1.
In addition, the doctrine of Universal Jurisdiction as promulgated in Vatican I leaves open the possibility that it could all happen again! Rome insists on (and preserves) it’s rights to intervene in any way in any church anywhere. That’s a pretty tough assessment but undeniably true.
In fact, the truth is the Eastern churches today are recovering their traditions at the behest of Rome, principally through the work of Vatican Council II and the efforts of recent Popes. Some of the Eastern Catholic churches are simply unable to undertake such sweeping reforms under their own authority (possibly excepting the Melkites). The Popes must throw their own weight and prestige behind the restoration efforts even in opposition to members of the Curia and some hierarchs in the Eastern Churches themselves.
None of this is lost upon the Orthodox who have been observing this process for 400 years at least (in the case of Italy, they have been observing the fate of their coreligionists for nearly 1000 years).
Orthodox Christians will not be pursueded by promises from Rome, they will accept nothing less than guarantees. Thus it seems that nothing less than a modification or repudiation of the doctrine of Universal Jurisdiction will be necessary to bring about an organic unity of the church East and West.
Alternatively, we might approach this without the goal of organic unity, but shared communion only. This still would raise difficulties because Orthodox are unable to share communion with church bodies they view as teaching heresy, and we are back to the fundamental objections that prevent an organic union.
