Another thought occurs to me, as I read the end of that introductory question…
The image of Papa for the Roman Pontiff, and why us knuckle-headed “Protestants” won’t acknowledge him as our head, leaves me with funny follow-on images…
For the Churches of Germany that embraced the Augsburg Confession, none of us wanted to leave the Bishop of Rome… we were even content to remain in the Roman Communion with him, as long as he could make room for us and our simpler expression of the catholic faith. Our Papa kicked us out of the house and tried to kill us for hampering his indulgence trafficking. When the churches in England and Scandinavia had similar disputes, our Papa booted them out, and tried to kill them, too. Bad Papa.
So, now that us wounded children feel safe enough to swallow our own pride and knock on Papa’s door, without fear of our Papa’s big political stick (somebody took that away from him, thanks be to God) the awkward reunion seems to be stalled at the front porch (post Vatican II.)
Papa: you’ve been bad, but we still love you-- join us.
Lutherans: if you promise not to try to kill us anymore, can we peacefully coexist?
Papa: well, maybe… as long as you swear an oath of loyalty to me that I’m always right, have always been right, and will always be right, and that you’ll never try to confront or reform me again.
Lutherans: Uh… that’s playing a little fast and loose with history, isn’t it? Besides, look at all the working of the Spirit of God in our communions over the last 450 years… wasn’t there some good that came of our conflict?
Papa: yeah, well, maybe… but you still have to swear that I’m always right… cuz I say that I am… and that means that I am… and this is my house, and as long as you want to be here, you’ll play by my rules.
Lutherans: Well, your rules today seem a lot better than your old Inquisitorial days, but if you won’t admit that you were ever wrong before, how can we be sure you won’t go back to your old abusive ways? Heck, you haven’t even made up with our distant Uncle Orthodox yet.
Papa: trust me!
Lutherans: Uh…yeah… we’re working on that trust thing… but we have some of our own baggage to sort out.
Papa: is there anything I can do to make you trust me?
Lutherans: hmmm… let’s call in a neutral arbitrator… or better yet, a real ecumenical council, with all the valid bishops from all over the world, seated together. We’ll agree to settle with whatever the mind of the whole communion is… will you?
Papa: hmmm… might cost me a little prestige, letting myself finally be accountable to someone, even if it is a truly ecumenical council, with the Orthodox and other legitimate bishops all seated with equal votes. Gosh, I don’t know…
Lutherans: see our trust issue better now?
