Is Mary's human soul pre-existent in eternity? There is a statement in the Catholic Catechism that says that Mary is chosen from all eternity by God. Would this mean she pre-existed in eternity with God, or does &quot;chosen&quot; not really imply pre-existence?
Mary's predestination:

488 &quot;God sent forth his Son&quot;, but to prepare a body for him, he wanted the free co-operation of a creature. For this, from all eternity God chose for the mother of his Son a daughter of Israel, a young Jewish woman of Nazareth in Galilee, &quot;a virgin betrothed to a man whose name was Joseph, of the house of David; and the virgin's name was Mary&quot;:
The Father of mercies willed that the Incarnation should be preceded by assent on the part of the predestined mother, so that just as a woman had a share in the coming of death, so also should a woman contribute to the coming of life.

What does the Catholic Church teach on Mary's soul?  Is there an official doctrine explaining that Mary's soul pre-existed in eternity?
In 1661, Pope Alexander VII released the Bull "Sollicitudo omnium eccl.," which reads in part:


  The devotion to the most blessed Virgin Mary is indeed of long standing among the faithful of Christ who believe that her soul, from the first instant of its creation and infusion into her body, was preserved immune by a special grace and privilege of God from the stain of original sin. (Denzinger 1100 – Latin "in primo instanti creationis atque infusionis in corpus")


This, combined with the general Catholic teaching in favor the creation of all souls (cf. Pope Pius XII, "Humani generis", "the Catholic faith obliges us to hold that souls are immediately created by God") and the Church's opposition to the pre-existence of souls, indicates that Mary is not an exception to the rule: her soul was immediately created at the time of its infusion into her body, in the womb of her mother.
