Theologians have given a rational explanation for her fullness of grace and why she cannot be subject to the devil: it was fitting that it should be so, God could do it, therefore he did it. That is the great proof: the clearest proof that God endowed his Mother with every privilege, from the very first moment. That is how she is: beautiful, and pure, and spotless in soul and body! (The Forge, 482)
Thou art all fair and in thee there is no stain. —Thou art a garden enclosed, my sister, Spouse, an enclosed garden, a sealed fountain. —Veni: coronaberis. —Come: thou shalt be crowned (Cant 4:7, 12 and 8).
If you and I had had the power, we too would have made her Queen and Lady of all creation.
A great sign appeared in heaven: a woman with a crown of twelve stars upon her head. —Clothed with the sun. —The moon at her feet (Apoc 12:1). Mary, Virgin without stain, has repaired the fall of Eve: and she crushed the head of the infernal serpent with her immaculate heel. Daughter of God, Mother of God, Spouse of God.
The Father, the Son, and the Holy Ghost crown her as the rightful Empress of the Universe.
And the Angels render homage unto her as her subjects... and the patriarchs and the prophets and the Apostles... and the martyrs and the confessors and the virgins and all the saints... and all sinners and you and I. (Holy Rosary, Fifth Glorious Mystery)
