So, to expound on the OP question, and in light of Jesus prayer in John 17:20-23, what are reaching your thoughts on the idea that Christian's of ALL rites should prioritize unity? It seems to me as I said before that there is an opportunity here, if not a responsibility for the church to work harder to this end. By "church" I'll go with CCC 751 (pic added).
And to more one claims, "The One True Church", perhaps the greater this responsibility. Perhaps that means finding a way to move to a more common ground.
There have been plenty of cross denominational talk through the past few decades. I'd say all sides are "trying" but we're starting very far apart so it's gonna take some time and spiritual help.
