I've been reading this thread and I just cannot believe what I'm reading!
You seem to have a contempt of the West and anything "western". Perhaps I'm perceiving incorrectly but that is how your posts come across. What's funny is that you're Serbian Orthodox, which is hardly the most "Eastern" of the Eastern Churches.
Anti-western bias is simply out of fear or perhaps misunderstanding of the West. Presbytera already explained that she doesn't want unity with Rome to come until Rome corrects it's dogmatic errors. But I suspect if tomorrow Rome repudiated the Filioque, Papal supremacy, the IC and the other Papal dogmas you'd still be against union because they don't use our liturgy, or they have statues, or they use Gregorian Chant, ie: they are too "latin" or western.
I admit, my perception could be totally wrong, but this is at least how your posts come off. Maybe you're not even aware of it. Maybe it's a cultural difference or something, but this is how I perceive it. Secondly, how do you think a Catholic feels when they read your posts? Good grief, why would ANYONE want to become Orthodox when they see such infighting not only between EO and OO, but such perceived anger at an EO Presbytera? (again, it could be a perception of the internet, and not really what is going on)
You've had Presbytera Mari repeat herself over and over again and still you do not read her words, but interprate them according to your own context. She's said about 3 or 4 times she doesn't accept the "branch theory", that Orthodoxy is the one true Church etc...
Lastly as far as whether Rome's Sacraments are valid, I find it funny that some Orthodox KNOW they don't have grace, and yet, the ancient Church accepted Arian baptisms. With that logic, Catholics are worse than Arians....I'm sorry, but that's total nonsense, and in the end it boils down to what God wants and decides. If God has so chosen to keep grace in Rome's Sacraments then that's His business and not ours. We shouldn't be judging such things that we cannot know about.
Sorry if I've misunderstood your words, but this is my impression from reading this thread.
