A book could probably be written on this subject, but I will try to keep it brief, and get to the heart of the matter. As Christians, our purpose is theosis, or union with God. Adam and Eve, before the fall, walked with God, and were born to become completely absorbed in the Godhead, and become like God. What was destroyed in the garden, has been restored through Jesus Christ, and humans can again attain communion with God. Before the fall, Mobiosity, life in the Garden was virginal. There was no sexual union until after the fall, when sin entered the world (Gen 4:1). Yes, God did make provision beforehand and made them male and female because He knew, through His omniscient wisdom, that the human race would dwindle away once death entered unless Adam knew his wife Eve, and she would bear children. Now, aside from after the fall and sin entering into the world, comes Mary, the first Christian. She said yes to God, whereas Eve said no. She is not simply any Christian, she is the Christian all of us strive to emulate (which is Eve
before the fall).
Mary attained perfection and Eve lost perfection. Mary is Eve, before the fall, when life was virginal and uncorrupt. This does not mean that the Church views marital sex as impure or unclean. It is the higher calling, and one that Paul himself, chose over marriage. When one is a virgin, they can attain perfection physically as well as spiritually. They are also able to devote themselves fully and completely to God. One way we know that Mary was a prophesed virgin, that she had devoted herself to God
fully, is by her statement to Gabriel . . .
how can this be, seeing I know not a man. She did not understand the implication of Gabriel's announcement of conception because she was a vowed virgin. There are also many OT prophesies of her remaining ever-virgin. She was the gate through which Christ entered and no man after, would enter in. Doesn't it make sense that Mary would remain untouched by any man? She contained the eternal God in her womb, yet lived! This is evidence of her Virtue and Grace. She is our Ark of the New Covenant. The ark in the OT was a shadow of what was to come. She is the burning bush which contained the Fire, yet was not consumed. There is much, much more. But I was trying not to write a book, so I will stop here. Mary's ever-virginity has been believed, taught, and defended by the Church for 2000 years. Even those who started the reformation, like Luther, Calvin, and Zwingli, believed in her Purity. Please forgive my long explanation. I hope it makes sense.
Love,
Christina
