There are two phases to Mary’s existence. The first phase was from the moment of her conception until the Annunciation, which is when Jesus was conceived in her womb. The second phase was from that moment of Jesus’ conception forward for all eternity. Each phase has its own physiological delight attached to it which required Mary to be a sinless vessel for Our Lord.
First, the pre-Annunciation period. As it has been discovered just within the last few decades, all baby girls have all of the eggs that are ever going to be in their ovaries fully formed not just at birth, but fairly early in their fetal development phase. Unlike men who are continuously producing new sperm, a woman’s eggs aren’t created and formed with each menstrual cycle. All that is happening during a cycle is that an egg, which has been fully formed in a woman’s body since she was a pre-born fetus, is released into the reproductive tract. What this means theologically is that the egg containing the 23 chromosomes that God would miraculously fertilize with 23 chromosomes that He miraculously supplied (including a Y chromosome) to become the Word Made Flesh, Jesus Christ, was physically present inside Mary’s body from the time that Mary was inside of her mother’s womb. That egg, and those chromosomes, that physical constituent of Our Blessed Lord was present inside of Mary’s body, waiting to be . . . if I may use the word . . . consecrated. The word consecrate, when broken into its Latin components means:
Ate: Territory of a Ruler
And so, Mary was, from the time she was inside St. Anne’s womb, already carrying a portion of Our Lord’s physicality, namely 23 of His chromosomes. And thus Mary was, from her very beginning, already a proto-tabernacle, already the Ark of the New Covenant, carrying within her what would be consecrated into The Law Incarnate, The High Priest, and The Bread of Life – just like the Old Ark, except perfected and fully fulfilled as God Incarnate. And as we know from the book of Exodus, the Old Ark had to be “perfect”. And thus, the Ark of the New Covenant was TRULY perfect, except this perfection was a perfection that only God Himself could accomplish: the perfection of Mary, full of grace and thus saved from all sin, including Original Sin.
The second phase is actually broken into two sub-phases. The first sub-phase is when Mary was pregnant with Jesus and His entire body was inside of hers.
The second phase is that phase from the time of Jesus’ birth forward into all eternity. Jesus is STILL physically inside of Mary in a unique way. It was discovered just a few short years ago that immune cells pass from a pre-born child to the mother across the placenta. Not only do these immune cells, which are the child’s and thus carry the exclusive and complete DNA of the child, pass across the placenta, but they persist in the mother’s body for the rest of her life. A woman who has carried a son has immune cells with Y-chromosomes in her bloodstream that can now be filtered out of her blood and observed. Female children also pass cells to their mothers.
Thus, a woman truly does carry her children around inside of her, with their DNA coursing through her heart, for the rest of her life. That isn’t just a sentiment – it is a physiological fact.
Thus, Mary continued and continues to this day to be a perpetual, living physical tabernacle of her Son, as she carries cells with His DNA in her bloodstream. And so now we see why Mary was and had to be filled with grace and thus saved from the stain of sin from the moment of her conception eternally forward – because she was and is a perpetual Ark of the New Covenant.
