I am just guessing here, but I don’t think reconciliation will come about through one all-encompassing meeting of the minds as a single Council. Most especially because the Latin church has enough bishops and abbots and other voting hierarchs that just putting them together in one place would swamp the proceedings.
In other words … if two groups meet in a binding assembly with one group having 3000 members while the other has 450, there will not even be dialog necessary. Just one vote and it’s all over, the smaller group would never agree to that ‘steamroller’ kind of Council.
Likely selected representatives of both parties will meet and hammer out some kind of agreement, which would go back to both parties separately for review and possible ratification in their own assemblies convened at a separate time and place. The back and forth could take years.
We have not even come close yet, all the dialog so far for the last forty years has been mostly discussing terminology and describing beliefs. The danger that we could be talking passed one another is huge. Once we really understand one another there is a great big process of sorting out what can be compromised on from what can not.
Then, after the inevitable impasse, everyone will go back and see if maybe they didn’t actually mis-understand one another after all …
I think it will take many decades, if ever.
