For the future, I would suggest avoiding subjects of too vast a scale. It would be useful to make out a list of fundamental questions on the matter to be dealt with, and discuss only those.
The mission proper to the Church is that of proclaiming the Gospel.
I believe that Orthodoxy has been thinking lately, and despite other impressions, that we can't have full sacramental communion if we don't first have a fundamental agreement on the question of the primacy, that still isn't there.
