Take the Blessed Virgin Mary out of the Bible and watch what happens...the Incarnation and mankind's subsequent salvation fail to happen.
And yes, I am familiar with the argument that God could have just picked any woman who was of the House of David, but He DIDN'T, he picked the Blessed Virgin Mary. The REALITY is that our Lord didn't need to be born of a woman at all, He could have just appeared as an adult, He CHOSE His mother.
Not at all.
God would likely have raised up a rock as a virgin of the lineage of David . . . maybe called her Martha . . .
and then the Vatican Edifice would have spent 1600 years worshipping Martha.
