Eighth Day
The faith of the Catholic Church on the conception of Mary, is this: that, at the very instant when God united the soul of Mary, which He had created with a special regard to the Mother of His divine Son, to the body which it was to animate, this ever blessed soul not only did not contract the stain of that curse which defiles every human soul, but was filled with an immeasurable grace, which rendered it from that moment the mirror of sanctity of God Himself, as far as this is possible to a creature. It was due to His own infinite sanctity that God should suspend, in this instance, the law which His divine justice had passed upon all the children of Adam. The relations which Mary was to bear to the divinity could not be reconciled with her undergoing the humiliations of man’s punishment. She was not only the Daughter of the eternal Father: she was destined also to become the very Mother of the Son, and the Bride of the Holy Ghost. Nothing defiled could be permitted to enter, even for the shortest time, that sacred structure.
Prayer.
O Lord Jesus, Who didst, for the love of us, etc., etc.
