Dear Friend,
Which “Easterns” insist that they don’t believe in Original Sin? You’ve opened up a whole new area of theological research that I didn’t know existed!
We “Easterns” do have problems understanding what Latin Catholic theology really means by “inherited guilt” (how could we inherit the personal guilt of Adam’s sin of disobedience? How is that possible?). This, to us, seems to be a carry-over from aspects of St Augustine’s theology and is entirely foreign to the school of the Cappadocian Fathers.
But for us “Easterns,” Original Sin is the death that we inherit as a consequence of Adam’s sin of disobedience and the damaged (but not completely) human nature where it is darkened and in a state of rebellion against God via concupiscence.
The Christian East has ALWAYS believed and affirmed and liturgically celebrated the Most Holy Virgin Mother of God as “All-Immaculate” and “All-Holy” and it was the East that began liturgically celebrating the feast of the Conception of Mary in the womb of St Anne - which means the East celebrated Mary as a Saint at the moment of her Conception.
Only in the Roman Catholic West was the opinion allowed that Mary was born with the inherited guilt of Original Sin until the Pope declared the dogma of the IC in the 19th century.
So without ever defining it dogmatically, the East has always glorified Mary as without ANY sin whatever because God sanctified her and poured out His Grace upon her from her Conception.
In addition, we also celebrate the Conception of St John the Baptist which also means that he was sanctified at his Conception in view of the great role he would play in salvation history - again without dogmatic definition.
Locally, we have the feast of the Nativity of St Nicholas which too suggests he was sanctified before he was born. We celebrate the dormition of St John the Evangelist/theologian into heaven, body and soul which likewise suggests a tremendous level of Grace for that great Saint of God.
And all this without dogmatic definition but based on the “lex orandi - lex credendi” principle.
The East never had to suffer any controversies about human nature and Grace as occurred in the West, especially with respect to Protestantism.
In fact, the Immaculate Conception doctrine would never have had to have been defined if the West had this same Eastern theological outlook.
The idea of “exemptions” is simply foreign to the East.
