Careful not to throw too many stones there, Gabriel. Why is the Roman Catholic Church not in communion with every community that calls itself “Catholic”, like the Polish National Catholic Church?
How can the Orthodox be one church when they have no one Vicar of Christ on earth that unites them all as one?
Why would the Orthodox subscribe to a Roman Catholic idea like their Patriarch(s) being the “Vicar of Christ” in the first place?
Can you define what you mean by “it is really one Church”? How is this visible on earth?
Why would you assume that it’s any less visible than in your church? I am not even a member of Schism Hater’s communion, but I’d be willing to wager dollars to donuts that they probably commemorate their Patriarchs (plural) at every liturgy, and that when someone from within the communion shows up to a church other than the particular one into which they were baptized (e.g., a Russian at an Antiochian parish or something like that), they all share the same cup. So I don’t see the point of this kind of questioning. In fact, in my 5-6 years in the RCC, I don’t remember any Patriarch of the Eastern churches being mentioned at all, while at the Ruthenian liturgy I attended, they definitely mentioned then-Pope Benedict (as is the case in the older recordings of the Maronite liturgy that I have, where they mention the Pope of Rome, as well as their own Patriarch). So from where I’m sitting it looks like the Orthodox are a bit balanced in their conception of unity than you guys are, since again, what makes us united is that we are in union with one another (EO with EO and OO with OO, of course), not that we are all under a particular bishop whose church and leadership largely doesn’t care about us. (The current RC Pope being something of an exception, I suppose, given the apparently role that the Greek Catholics had in his formation, but we’ll see if this has any practical effect on how things are. I kinda doubt it will.)
Because the Orthodox church’s are all independent of another, some Orthodox churches accept contraception and divorce, while other Orthodox churches hold to the Pope’s line of teaching on contraception and divorce by not allowing the practice.
Such things are largely considered pastoral matters, and hence governed by economia. That you see this as “some churches agree with the Pope but others don’t” just shows how unhelpful your Rome-centric ecclesiology is to actually understanding the answers Schism Hater might give you. That’s pretty funny in a conversation about why we aren’t in union with Rome. Many RCs seem to believe that this is stubbornness and an accompanying inability to see how good you guys have it, what a great benefit to unity it is to all be with the Roman Pope, etc. You only focus on what you have and how we fit into it according to you, and are completely unable to grasp how things can work differently without Rome being in the picture.
You see we don’t have that kind of freedom in the Western Church to believe independently apart from our unity to the head who is Christ.
Be sure to pass that message on to your own. I know there are plenty who need to hear it.
