My Christian training emphasized the uniqueness of the Christ as the only human ever directly created since Adam,thus the only one ever born of woman that could offer a propitiatory sacrifice that would exactly cover the fall of Adam.
Catholics and some Protestants regard Mary as having had a similar special conception that left her perfect to be the mother of God.
My question is if Jesus had to have a perfect mother to be perfect, would not Mary also have had to have a perfect mother to be born perfect?
And her mother the same and her mothers mother the same and her mothers mothers mother the same etc....
Would it not make much more sense to conclude that just once in all history the Creator of Adam created another perfect human by miraculously adding the necessary spark that initiated the process known as fetal development from the ovum of Mary?
