There are many Orthodox Churches around the world like Syrian Orthodox, Antocian Orthodox, Russian orthodox, Armenian Orthodox, Indian Orthodox, Coptic Orthodox, Ethiopian Orthodox, Cupriot Orthodox, American orthodox etc. and it will be nice if all the Orthodox Churchec together form a council in common and that may enable to have co-operation among all these Orthodox churches Globelly.
That's a nice idea. One issue, which you can read about on this board, is you're talking about not one but at least two 'families' of Eastern churches, the Eastern
Orthodox such as the Russian and Cypriot Orthodox, and the Oriental
Orthodox such as the Syrian (including Indian), Coptic, Ethiopian and Armenian churches. (The third group is the Assyrian Church, Church of the East or what used to be called the Nestorians - they're the historic Church of Iraq.)
What you describe could happen in future as the two sides are very close now - most experts think the split between the two groups was a big misunderstanding - but not just yet as they're not formally in communion. Moderator Phil Mathew (Mor Ephrem) is a member of the Malankara Church, the Indian branch of the Syrian Church, and can better describe this for you.
I personaly do not think that there will not be any benefit of having the dialogue with the Catholics as the basic principles of the Catholics will not change instead of that they are trying to absorb the Orthodox under their supremacy.
No, they won't and they wouldn't deserve any respect if they did. What can change is not the theory
behind it but how
the papacy is used. As for absorption, on one hand there's a stack of RC documents denying that the Orthodox would be changed, but on the other there is the sad experience of the Eastern Catholic churches being second-class subjects and self-latinizing, changing their rites to be more like RC for no good reason. (The stack of documents tells them not to but they did it anyway.)
The Catholics teaches that Pope is unquestainable and he is sinnless
No on both counts. He's unquestionable only in certain situations that are very rare and he isn't sinless. John Paul II, for example, goes to Confession at least every week.
but the Orthodox teaching is that no one is sinnless except Te Trinity.
Both sides agree on that - God is sinless in Himself, others such as Mary were made sinless. Both sides say she is immaculate (-+-ÃƒÆ’Ã¢â‚¬Â¡-Ãƒâ€šÃ‚Â¦-+-Ãƒâ€šÃ‚Â¦-+-+-ÃƒÆ’Ã¢â‚¬Â¡-+-ÃƒÆ’Ã‚Â§-+-Ãƒâ€šÃ‚Â¦-ÃƒÆ’Ã¢â‚¬Â¦ in Russian)
And the Catholics teaching about St. Mary is that St. Mary is born with a pre-concept to conceive Jesus hense the Catholics celeberating the birthday of St. Mary but we Orthodox respecting St. mary as the mother of God since she conceived Jesus.
You're setting up an opposition where there isn't any. See above, and both sides celebrate both her conception and her birthday.
We the Orthodox is celeberating the only birthday and that is of Jesus Christ our Savior.
No. You also celebrate the birthdays of Mary and St John the Baptist.
The rest we are celeberating the day of the departure as it is the birth to the eternal heavenly life.
As does western Catholicism.
Do the Catholics change these basics?
