If she gets an exemption, then why not the rest of us? "special consideration" = sinless = no need of a savior. What, there isn't enough of that "special consideration" to go around? Undermines the whole salvation process at the nexus of it happening.
Not true.
Oh, please.
Her "special consideration" is directly tied to the irrefutable fact that a person -- even a Divine one -- with a fully human nature must (by definition) be brought into this world through a natural birth. Jesus Christ -- whose Divine existence as the Son of God meant that He existed for all of eternity outside the physical and temporal constraints of the natural world -- could only have one human mother. He could not have two mothers, He could not have 73 mothers, and He could not have come into this world with a litter of puppies.
That one human being who was selected to be His mother would certainly -- by her very nature -- occupy a very special (no, UNIQUE) place among all of the billions of people who have existed and who will exist.
