LCS, I've reading what you say with interest and I love to learn about the medieval period. So, on that note, is there any reading you could recommend to me?
Depends. Can you read french? If not, I don't have most clues to give to you.
It didn't help that the Pope and all priests blamed all woman as the source of the fall from grace. This devaluation of women spread as Christianity did (I'm sorry to say).
That's one of the big misconceptions about medieval society that can't be really supported. Christianity, not alone on this admittedly, represented a huge progress into institutional acknowledgment of women : while the traditional roman woman (to not say greek) was considered an eternal minor and really managed only in the Late Antiquity to have their own names.
Roman relatively widespread infanticide, on this regard, may have targeted girls in a similar manner than what caused the birth unbalance between men and women in some modern countries.
On the other side, while women were still under a lower consideration overall, well...they did were considered as spiritual equals of men, at least theologically and institutionally : it's not that rare to see abbesses having a religious power over monks or lay brothers (not rare, which isn't the same than common, it remained particular to coupled houses).
Not that Church didn't played a role into maintaing women in relative lower consideration : it "theologized" the lower station.
That said, a lot of Eve-related interpretations purposely devaluated women in order to get a better comparison with marial themes, especially in the XIIth century.
Spiritual individuality, and not only based on familial spirituality, is probably one of the biggest changes from classical Antiquity that was maintained up to the end of MA, without this individuality being systematically tied to purity and virginity (not that it was a clear politic from the Church, but rather the middle-way they attempted to maintain between irreligion and heterodoxial puritanism)
Mariage becoming a sacrament in the Middle-Ages is as well a novelty on this regard, as it made union no longer a simple contractual agreement dominated by men (repudiation of spouses and/or polygamy de facto wasn't rare up to the classical medieval era), but a spiritual matter on which the women were technically equal to men and able to push for their interests (and while never really fully applied by lack of possibility, consent in mariage and sexuality really made its spiritual apparance).
TLDR
While the theologisation of the lower station of medieval women certainly did its part into maintaining the said lower station, you had as well the appearance of a first accounted spiritual independence and individuality that answered to the known social independence and individuality : as I tried to point in my first post, neither gender harmony, but neither gender "minorisation".
