Alas, I think it an unlikely possibility- I believe the Reformation has formed an irreparable rift between our two confessions. One that cannot be healed without certain instruction from the mouth of our Master. I take it, by good estimation, that we will have to be content to pester each other until the end of the age- Not an insufferable length of time, by any account.
Not that our time cannot be well spent... For there are many things that we agree upon, and we can, and do go forward together in that respect.
[...] as the RCC has found a way to heal its own relationship and origins with the Jewish people (now seen by the RCC as being in an irrevocable salvaic Covenant with God while comprising, with the Church, the People of G=d, etc.)...
My position mirrors your own. Jehovah says He has two witnesses on this earth, that one is Judah, and the other Ephraim. One cannot see, and one cannot hear. I think that Judah worships in a synagogue, and Ephraim (by some near miraculous contrivance) worships in a church. The people of Israel have much to do even yet, before we see the coming of the Messiah.
Some of the leading Protestant denominations have done likewise, so perhaps (for He does indeed work in strange ways!) this area of agreement within today's Christiandom may blossom some flowers of harmony between and amongst the Roman Catholic Church and Protestantism?
Who can say? But I think that such a condition is afar off as long as Rome supposes the Protestants will ever submit. Our paths have long wandered apart, and those things which Rome insists upon are the very things which Protestants will never abide.
One good thing, certainly much of the most heated invective and antagonistic preaching has been, well, toned down in recent times. When the heated shouting is turned down, we all may better hear the quiet voice of God.
On that we can agree.
Best regards to you too.
"Let us also pray for the Jews: That our God and Lord may illuminate their hearts, that they acknowledge that Jesus Christ is the Savior of all men."
Step backwards? Perhaps. It certainly resulted in many forced "explanations".
