Drunk, I think we actually agree on this. You should understand that for me the term "orthodox Christian" includes the Catholic Church, which is the faith in which I was born and raised. I don't mean to sound overly judgemental of Catholics. I have a profound respect for that faith, but I differ from it on many fundamental issues of which this is one.
My understanding of women in the New Testament is largely as people seen as sinners and generally unclean who were forgiven and accepted by Jesus. Its been mostly in the gnostic texts, with the notable exception of Paul who is included in the New Testament (I think you'll find that Paul is the author of most of the references you cited above), that women are shown to be accepted as equal to the apostles on their own merit rather than generally likened to other sorts of sinners.
Then we have this enlightened progression after Jesus death:
St. Tertullian (about 155 to 225 CE):
"Do you not know that you are each an Eve? The sentence of God on this sex of yours lives in this age: the guilt must of necessity live too. You are the Devil's gateway: You are the unsealer of the forbidden tree: You are the first deserter of the divine law: You are she who persuaded him whom the devil was not valiant enough to attack. You destroyed so easily God's image, man. On account of your desert even the Son of God had to die." 1,2
St. Augustine of Hippo (354 to 430 CE). He wrote to a friend:
"What is the difference whether it is in a wife or a mother, it is still Eve the temptress that we must beware of in any woman......I fail to see what use woman can be to man, if one excludes the function of bearing children." 10
St. Thomas Aquinas (1225 to 1274 CE):
"As regards the individual nature, woman is defective and misbegotten, for the active force in the male seed tends to the production of a perfect likeness in the masculine sex; while the production of woman comes from a defect in the active force or from some material indisposition, or even from some external influence."
Martin Luther (1483 to 1546):
"If they [women] become tired or even die, that does not matter. Let them die in childbirth, that's why they are there." 9
Yes, I have read two of Elaine Pagels books, The Gnostic Gospels and Beyond Belief. I found both to be quite readable and informative. I did think her presentation was a bit biased, but certainly not the most biased that I have read and considered. Most of the gnostic approach appeals to me, but there is an inherent arrogance in their thinking as I understand it that puts me off.
