I understand everything you’re saying but what you’re saying does not negate the problem of denial of a dogma. Dogmas are Theologia prima or essentials hence they are called dogmas.
The Church, East and West, have their own theological expression. Because for centuries Rome thought itself as the
only true Church the doctrinal pronouncements of the Church of Rome were often labeled as “dogmatic,” but in actuality, they were
only particular to the Church of Rome. So, not everything Roman Catholics consider “dogmatic” really is. As long as there is agreement on the level of the
theologia prima (the Theotokos is sinless), variety in the
theologia secunda (the Wests understanding of the Immaculate Conception) is acceptable and, in all actuality, desirable. This is why, I, as a Byzantine Catholic, have not problem accepting the Roman Catholics understanding of the IC or Purgatory. As long as the Church of Rome does not push these ideas on us.
What I’m saying is if were are in communion that means we have the same faith.
We are in communion with one another (Byzantine Catholics and Latin Catholics) and share the same faith but, communion does not mean we are “rites” of the Roman Catholic Church. We are not Roman Catholics with a different “Mass.” Vatican II did away with that idea. We are our own Churches, with our own ecclesiastical heritage. Often times people thing that a “rite” is only that of a liturgical patrimony. It’s much more. Our liturgy reflects the fullness of our Tradition (spirituality, theology, etc.).
There is the catholic faith and in the Catholic Church the Filioque, Immaculate conception, original sin, Papal infallibility and Universal jurisdiction are dogmas and cannot be denied under the pin of anathema. It’s that simple. Denying them is like denying the Hypostatic Union, Mary as Mother of God etc. You simply can’t if you wish to be called a catholic.
Again, these are “dogmatic” pronouncements of the Church of Rome. I think you need to read more about what Rome teaches about the Eastern Churches, both Catholic and Orthodox. By the way, Pope Benedict XVI (then Cardinal Ratzinger) wrote, Ratzinger wrote that, “Rome
must not require more from the East than had been formulated and what was lived in the first millennium,” and, “Reunion could take place in this context if, on the one hand, the East would cease to oppose as heretical the developments that took place in the West in the second millennium and would accept the Catholic Church as legitimate and orthodox in the form she had acquired in the course of that development, while on the other hand, the West would recognize the Church of the East as orthodox in the form she has always had.”
