Greetings in that Divine and Most Precious Name of Our Lord and Savior Jesus Christ!
If it is NOT the one true church, then the Eastern Orthodox church is phony.
It either IS or IS NOT the one true church with grace.
This is why EO are not in communion with the OO churches.
I'm sorry to say but that is a rather historically inaccurate, shallow, and disingenuous analysis. Of course it has already been point out kindly to you
The premises of your argument are proved manifestly false by church history therefore your whole argument collapses.
Likewise even during the most severe periods of persecution by the Byzantines the Orthodox always insisted that the sacraments of the Byzantines were real and never baptised, chrismated or ordained any who joined the Church.
So your insistence that grace is not present in the other communion is both false and un-Orthodox.
The Churches do not disrespect the sanctity of each other as sisters, the issues with closed communion are often largely more about sociopolitical issues more so than any kind of historic or theological grounding. Most Churches mutual respect the disciplines of each other in regards to all Divine Mysteries (including weddings and even baptisms) without exactly disregarding each other.
That's the problem: they don't. Many OO are now ecumenist heretics.
Easy with all that mama-grizzly style fire and brimstone
There are two things wrong with that statement
a) You have it backwards, OO tend to be the ones who resist reunification, even when seemingly cooperating in the past 45 years of good dialogue, clearly since the 600s its we OO who have all the grievances and therefore continually decide to stay separate despite hundreds of invitations
b) I don't quite like the spirit of your attitude, it seems a bit to hostile and that is unfortunate, as we are all Christians here.
And further, I'm a bit baffled at how Ecumenism has become such a four letter word on this forum, since when was the concept of Christian love and unity such a negative thing? In time shouldn't we in God's Grace be happy to work towards open reunification of the One, Holy, Catholic, Apostolic Church? This whole drawing lines in the sand thing has gotten exceptionally cliched..
