I found Sister's mentioning the Eastern Rite Catholics as a possible sign of how we go forward quite interesting. I'd need to find an article either in the archives here or elsewhere giving an even-handed explanation of how those Eastern Rite folks operate in union with Rome. Sister says they kept their own traditions, their own histories, their own liturgies etc. However, I always thought they had to abandon some dogmas of Eastern orthodoxy, and add dogmas specific to Roman obedience. Moreover, they also had to accept not just the primacy of the Roman pontiff but the near unlimited powers of that office which is so very different from the role of the Oecumenical Patriarch who is primus inter pares.

If we in the mainline are to find ourselves, as Jesus would want in a "Church of God" with God, as head, (but with a servant model human leadership of the visible church) then the role and powers of the Bishop of Rome need to change, at least with respect to the non-Latin rites in union.
