Her name is מִרְיָם which you know as Miriam or Mary.
She is the virgin of Israel who bore the man child whose name is called עִמָּ֫נוּאֵ֫ל which means "God with us."
Rev 12:1 And there appeared a great wonder in heaven; a woman clothed with the sun, and the moon under her feet, and upon her head a crown of twelve stars:
Rev 12:2 And she being with child cried, travailing in birth, and pained to be delivered.
CCC 491, “Through the centuries the Church has become ever more aware that Mary, "full of grace" through God, was redeemed from the moment of her conception. That is what the dogma of the Immaculate Conception confesses, as Pope Pius IX proclaimed in 1854: The most Blessed Virgin Mary was, from the first moment of her conception, by a singular grace and privilege of almighty God and by virtue of the merits of Jesus Christ, Savior of the human race, preserved immune from all stain of original sin.”
Rev 12:2 And she being with child cried, travailing in birth, and pained to be delivered.
Notice that part of the curse is pain in childbirth. This is why women suffer during the birth process. So, when we look back to the text of Revelation 12:1-2, we see that the woman clothed with the sun is suffering birth pain. Since the Roman Catholic position is that Mary could not be suffering birth pain (because of her Immaculate Conception and no Original Sin), then these verses cannot be about Mary.
Sure makes your Catholic religion look stupid when it contradicts itself (as well as the scriptures)...
Believed only because Rome wants to make her a goddess.
It doesn't say so in Revelation so claiming it is Mary is pure speculation.
