Not at all. Whatever you call them, they are the fruit of the Protestant Reformation. I want to be part of the true Church... I used to be certain that was the Roman Catholic Church. Now I'm not so sure. I'm looking East... but not sure where to go.
Then I think there's no alternative but to look into Chalcedon. Do you agree with the Chalcedonian or non-Chalcedonian position? If like some of us (myself for instance) you think that both sides are effectively saying the same thing, then I think you still have to work out who you think is in schism from whom. It's messy, it's ugly and it's tragic, but if you really are in a quandary, I can't see any way of avoiding taking a good hard look at it.
Why do all Catholics ( by that I mean E.O , R.C and O.O) See that the church cannot exist as One in faith no matter the internal divisions?
For instance when St. Mark had his differences with St. Paul did the Christians say Are you part of the True Church of St. Mark or are you with Pauls Church??
The same thing when St. Peter and Paul differed. Did not St. Paul say that we should not make the Church based on people.
Is our Faith the same or not?
I know a lot of E.O who make up stuff about the Copts and it really bothers me. They keep inventing things that we believe in which we Don't. It's time to accept that the Apostolic Church can exist despite our internal human differences.
When Joseph (the son of Jacob) was abandoned in Egypt by his brother did he stop being (Orthodox?) in his faith with God?? He was separated from his brothers... But God still saw him as Israel too. (Aka the Church).
Being Orthodox is about the Correct Apostolic Faith not just being connected to Greece, Alexandria, or Rome.. Yes the Church has its differences because man err.
To the OP - As a Coptic Orthodox I will not tell you what to Chose but I would be happy if you go either way because deep down I know both the O.O and the E.O have the same believes about the Son of God; and hold the True Apostolic Faith.
But what about the person in church who knows deep down in their heart that the Protestants have the same true Christian faith as us?
It is not for us to decide these things, when we do, we place ourself above the Church, rather than in obedient submission to her. This is a spiritually dangerous place to be.
St. Paul and St. Mark did not anathematize each other. This is the difference with the scenario you present. There are many disagreements between hierarchs in each Communion, but they are still in Communion. The EO and the OO are not.
Whether we agree or disagree with that position (and I, like you, think it needs to change) if we place ourselves above the Church and say that the declarations of the Church don't matter, then we are trusting in our own judgement instead of the judgement of the fathers. Who are you or I by ourselves to decide where to draw the line? EO, Catholics, Nestorians, Protestants, Mormons, Buddhists? You may say I'm being ridiculous because you know the line you're drawing after EO is right... but what about others in our Churches who know just as well that Protestants are the same too? It is not for you or I alone to draw this line, but the the Church, that is, all of us together, under the leadership of the bishops, to draw the lines together.
