I think Lydia's comments above cut to a much cleaner, deeper level of truth.
The tactic of "Dialogue" is so over-used. It usually means people sitting around, yes, drinking COFFEE !, and chattering, without accomplishing a whole lot.
It looks good to supporters or followers, whether Church or political, but usually goes nowhere.
Seems to be a "stall" measure more than anything constructive!
The problem, as Lydia says, lies in the stark REFUSAL of one party to fully admit they had the wrong belief and renounce that.
USUALLY : Fragile egos and negatively stubborn mental attitudes are involved, rather than the kind of humility which is required to make major steps
forward to get out of a long-festering impasse.
I think it would be great if Metr Agafangel, who seems to be drawing nearer to our way, would make that unilateral declaration.
And SiR along with him.
Then there could be real progress.
Hope Met Agafangel will consider this step. Surely much was done in haste in the early post-union days.
Maybe there was no adequate time to evaluate with whom he teamed up as "sister churches".
Perhaps now the time is ripe for reconsideration on the part of both Cyprianite factions ?
