As someone who is new to Catholicism, I am very confused by this as well. Wasnāt the Immaculate Conception dogmatically defined? Am I not expected to believe in this doctrine, no matter which church I am in?
So does this mean if there are certain doctrines I donāt quite see eye to eye on, but I find that Eastern theology aligns more closely with those beliefs, I should just join the Eastern Catholic Church?
It just seems to me āin communionā is sort of superficial. Just my humble opinion. I know there is a lot I donāt understand yet.
A lot of it has to do with legalism. The legalism is in the idea that only one theological Tradition, with accompanying theological language, is the ONLY ONE that is true. the Latin Catholic Church used to have this problem, and Latinizations abounded when the Eastern and Oriental Churches first came into communion with Rome. That is no longer the way it is in the Catholic Church. The Catholic Church understands that there is a Faith that is even more basic than theological expression. We must look for commonality in this Faith, instead of insisting on homogeneity in theological expression. It is what St. Paul exhorts us to do, as evident in my signature line below.
Eastern Orthodoxy, on the other hand, seems to have an undercurrent of legalism that opposes this kind of rapprochement. That is why many EO today do not accept the OO as Orthodox on the matter of Christology - because they think that only way to understand orthodox Christology is to use the terminological premises of the Chalcedonians. It is the same way in their relationship to the Latins on a lot of theological matters. Many of them cannot get beyond the theological terminology to understand the basic Faith that unites us all.
That is the same way with the Creed. It might interest you to know that during the Third Ecumenical Council, many of the Council Fathers chided Pope St. Cyril of Alexandria for not sticking to the theological expressions used by the Nicene Creed in his remonstrances against Nestorius. Pope St. Cyril correctly shot back that our Faith is
not contained in the Creed alone, but in all the sources that Sacred Tradition provides.
To think that a line in the Creed can separate the common Faith of the Catholic Church is mere legalism.
As far as the Immaculate Conception is concerned, the real problem is that many Latins themselves do not understand what the Immaculate Conception teaches. Many Latins think that the Immaculate Conception refers to Maryās PHYSICAL conception. With that misunderstanding, many Latins (and many non-Catholics, for that matter) think this means that Mary was preserved from the physical consequences of Original Sin. If that is the case, it would indeed run counter to the Eastern Tradition. However, the doctrine and dogma of the IC actually
only refers to Maryās SPIRITUAL state. It simply means that Mary, at all points in her existence, was never once separated spiritually from God by an act of Godās Grace.
Take special note that the Dogma of the IC DOES NOT STATE that Mary was preserved from Original Sin. Rather, it states that Mary was preserved from the STAIN of Original Sin. In Latin theology, the āstain of Original Sinā refers to the
spiritual consequences of Original Sin,
not the physical consequences (physical death, old age, disease, emotional instability, etc.). Understanding that, one can see that the IC in no way contradicts the Eastern Tradition, despite the claims of non-Catholics.
I hope that helps.
