I’m what you’d call a Latinized Ukrainian Greek Catholic. When my siblings and I were little, we learned the Latin version of the Hail Mary, Act of Contrition (which I still use) and Guardian Angel prayer. Most of my books are traditional RC books, although I do have a nice collection of EC books and a few EO books.
I’m still learning about Eastern theology and imo, some things are complementary to Scholastic theology and others baffle me.
In every Liturgy, we commemorate “…our most holy, immaculate, most blessed and glorious Lady, the Mother of God and Ever-Virgin Mary.” Yet we are not supposed to profess the Immaculate Conception because it’s based on the Western teaching of St. Augustine re original sin.
The dogmas of the Immaculate Conception and Assumption are inextricably linked. As I previously posted, since death is the punishment for sin (that’s in the Epistle of St. Paul to the Romans), it stands to reason that since She had no sin therefore She could not die.
I love the Byzantine Tradition but quite frankly the Latin Tradition has given the whole Church, East and West, some good things too.
Personally, I see no problem. As one of the Saints put it: it is safer to attribute to Mary whatever is more excellent. (It’s in The Glories of Mary.)
