Returning the Bishop of Rome to the dyptichs is an obvious one and will be the action by which Communion will be restored, not a requirement to restore it.
The rest of what you wrote, sounds very much like a “Our way or the high way” sort of thing, couched to avoid mention of “the contested doctrine”.
Asking that you guys cease to claim “that the contested doctrines are heretical” is not a “my way or the highway” attitude, for this one simple reason:
It does not in any way require you to accept
any of the contested doctrines in any form whatsoever.
We believe that they are orthodox, and that they have not added to the deposit of faith. Our faith in that belief is confident enough that we are willing to hand you a
blank check, by which you would be entitled to continue to deny
whatever you feel we’ve added… any of these matters, like purgatory, the Immaculate Conception, papal infallibility… we’re convinced that
what you’d be denying, we don’t actually believe anyway. We really are.
So not contesting the orthodoxy of the disputed doctrines is
not a “my way or the highway” attitude. Asking that of you requires no change or addition whatsoever on your part…
all it asks is that you believe us when we say, “We actually agree with what you say on this doctrine,” and when we say, “You are free to refuse to accept whatever part of it that you consider heterodox, and we will disown that interpretation/part of it.”
I do not yet think the typical Orthodox mind has grasped the extent to which the Catholic Church today is willing to admit that every contested part of these doctrines stems from Latin expressions - and therefore expendable components - rather than core concepts of these doctrines.
SIDE NOTE: The lack of understanding of what I’ve just tried to explain is, by the way, the source of the cognitive dissonance found in discussions over the “Ratzinger Proposal” (which asked only two things: that Orthodox accept that Rome is not in heresy, and that Rome require
nothing from the eastern churches that was not already a reality in the first millennium): does that not mean that the Orthodox should be allowed to deny some of these “contested” doctrines?
Many Orthodox - and eastern Catholics - say yes. Some Latin Catholics would be tempted to say no… and
those from any church who understand this “blank check” we want you to accept understand that the question itself is meaningless: you don’t really deny these doctrines anyway… only the Latin formulations of them which are in no way universally binding. (Original sin is the best example I can think of for this…)
