The feast of the Holy mother is feast for every woman. Because a woman, Maria, was the worthy one, so god to incarnate by her. God did not came to our world like a UFO, or other powerful creature. He became a baby, like us , so to be one of us, and grand us to be His real brothers and sisters.
We see a deep meaning of womanhood, beyond gender. To receive God. God created the world in order from the world will come as fruit Maria, so that he can become man.
Most of the biblical things depict the Holy mother. The most holy of the Jewish temple was an empty box, the symbol of the Holy mother, in whom the Logos entered.
