The role of women in religion can be examined from the point of view of the extent to which it is mundane - i.e. to do with the conduct of mortal life in this world; or cosmic - i.e. concerned with eternal matters and existence outwith this mortal life.
A cosmic role for women could be a religion where the creator was a woman, or when one or more of the god's was a woman - and there are also other possibilities.
My main interest is in Christianity. In historical Christianity we can see a cosmic role for the mother of Jesus in both the Eastern and Western Catholic churches.
And Mormons regard God the creator as a dyad of man and woman - Heavenly Parents who manifested divine creation and (in some literal sense) procreated Men.
Other types of Christianity among Protestants have essentially zero cosmic role for women; and this applies to Judaism and Islam.
As regards a mundane role for women - this is seen in terms of supernatural help with everyday life. This could range from a theologically formal role of female saints and other holy women in helping with various problems of life; to all kinds of unofficial, popular and folk beliefs of the same kind; that shade-off into superstitions and "luck" (and may occur even in what are officially strictly monotheistic religions).
At a further remove, there is the matter of women's role in the various churches. In some religions women have a essential role in churches, but in historical Christianity this has not been the case.
Sometimes all essential church roles were restricted to men, but in all instances women were inessential to the work of the church. The religion can be conducted entirely without participation of women.
Another vital aspect relates to Jesus Christ.
When it comes to a cosmic role for women in the life and work of Jesus Christ, historical Christianity has either had none; or has focused exclusively on the mother of Jesus whose role is probably only of explicitly cosmic significance relatively late in the history of the Roman Catholic Church - with the doctrine of immaculate conception.
Even the mundane role of women in the usual versions of the life of the adult Jesus during his ministry is minor to the point of being inessential.
This is (variously) a consequence of taking either the whole-Bible, or the whole-New-Testament (or Synoptic Gospels, or Pauline Epistles) as the major basis for Christian assumptions, and also of deriving core assumptions of church authority, tradition and a lineage of theology and practice dating back to Church Fathers.
However, my understanding of Christianity is focused upon the Fourth Gospel, regarded as the earliest and most authoritative source of knowledge.
As such, I see a potentially cosmic role for Mary Magdalene; who I believe to have been the wife of Jesus, and brother of Lazarus - whom I regard as the author of the Fourth Gospel.
Here - in brief - is what I regard as the description of Mary Magdalene's cosmic role in the work of Jesus Christ - using the Fourth Gospel (see this link for further discussion and more detailed referencing):
The Marriage at Cana (Chapter 2) is a rather garbled and tampered-with account of Jesus's marriage to Mary Magdalene - and it was the time of his first miracle.
I assume that Jesus became aware of his divinity at the time of his baptism by John; but he did not perform a miracle until he was married to Mary; which marriage therefore implicitly has a cosmic dimension, far beyond any mundane earthly ceremony.
Jesus encounters Mary on the way to resurrection of Lazarus (Chapter 11) - his profoundest and greatest miracle - the first resurrection.
Then again at the episode of the mysterious episode of the anointing of Jesus's feet by Mary (Chapter 12) - when he realized and announced that his death was imminent.
Mary Magdalene was present (with Jesus's mother, other women, and Lazarus) at Jesus's death on the cross (Chapter 19); and was then the first to meet him two days later when resurrected (Chapter 20).
I take these descriptions - bracketing Jesus's death and resurrection - to imply that Mary had some cosmic role in these unprecedented and eternally significant events.
The last we hear of Mary and Jesus is when he tells her: I ascend unto my Father, and your Father; and to my God, and your God.
Which I regard as an anticipation of the continuation of their eternal, cosmic marriage in Heaven, after Jesus's ascension and Mary's resurrection.
