Now, Pastor John MacArthur and some pastors of the Protestantism said that it was not Mary who is in the Rev. 12, the Woman. Catholic Church said that it was Mary who was been attacked by the Devil. Gen. 3:16 is what now Mary done, crushing Satan in her heel that Eve can’t do in the beginning.
As Cathecism of the Catholic Church stated in paragraph 966…
966 “Finally the Immaculate Virgin, preserved free from all stain of original sin, when the course of her earthly life was finished, was taken up body and soul into heavenly glory, and exalted by the Lord as Queen over all things, so that she might be the more fully conformed to her Son, the Lord of lords and conqueror of sin and death.” The Assumption of the Blessed Virgin is a singular participation in her Son’s Resurrection and an anticipation of the resurrection of other Christians:
In giving birth you kept your virginity; in your Dormition you did not leave the world, O Mother of God, but were joined to the source of Life. You conceived the living God and, by your prayers, will deliver our souls from death.
Associated with Scritures about a Virgin(not Israel) who will bear a Child.
 Therefore the Lord himself shall give you a sign. Behold a virgin shall conceive, and bear a son, and his name shall be called Emmanuel.
Supported by Gospel of St. Luke(1:26-35)
 And in the sixth month, the angel Gabriel was sent from God into a city of Galilee, called Nazareth,  To a virgin espoused to a man whose name was Joseph, of the house of David; and the virgin’s name was Mary.  And the angel being come in, said unto her: Hail, full of grace, the Lord is with thee: blessed art thou among women.  Who having heard, was troubled at his saying, and thought with herself what manner of salutation this should be.  And the angel said to her: Fear not, Mary, for thou hast found grace with God.
 Behold thou shalt conceive in thy womb, and shalt bring forth a son; and thou shalt call his name Jesus.  He shall be great, and shall be called the Son of the most High; and the Lord God shall give unto him the throne of David his father; and he shall reign in the house of Jacob for ever.  And of his kingdom there shall be no end.  And Mary said to the angel: How shall this be done, because I know not man?  And the angel answering, said to her: The Holy Ghost shall come upon thee, and the power of the most High shall overshadow thee. And therefore also the Holy which shall be born of thee shall be called the Son of God.
So, is the woman in Revelations a nation? Or really a woman named Mary?
You should be the judge! 😇
