Orthodoxy does believe Adam’s sin caused something, right? And we believe Theotokos was free from it’s effects.
This makes no sense and imo derogates from the infinite dignity of Our Lord and His Immaculate and Ever-Virgin Mother.
If She inherited “both the propensity to sin and to death” then how could She be Theotokos? God created Eve immaculate (Gen. 1 & 2; Eve sinned in Gen. 3) so why would He not do the same and even more for the Woman who would bear His Only-begotten Son and thus crush the head of the serpent? Gen. 3: 15:
[15] I will put enmities between thee and the woman, and thy seed and her seed: she shall crush thy head, and thou shalt lie in wait for her heel.
[15]
“She shall crush”: Ipsa, the woman; so divers of the fathers read this place, conformably to the Latin: others read it ipsum, viz., the seed. The sense is the same: for it is by her seed, Jesus Christ, that the woman crushes the serpent’s head.
When two persons are at enmity, they have nothing in common, they don’t speak to each other etc. Wisdom 1: 4:
For wisdom will not enter into a malicious soul, nor dwell in a body subject to sins.
She would be unworthy of the dignity of Theotokos if She had “both the propensity to sin and to death”. God ordered that the Ark of the Covenant (which the Holy Fathers say is a type of the Theotokos) be covered with gold
inside and out. Obviously, no human goldsmith could make the gold absolutely free from impurities.
The Annunciation:
[28] And the angel being come in, said unto her: Hail, full of grace, the Lord is with thee: blessed art thou among women.
Chairo, kecharitomene…
God in His Infinite Mercy willed that the Woman who would bear His Only-begotten Son would be immaculate. Only He can do this because He is Almighty. C.f. Hymn of the Theotokos (Magnificat).
