The Immaculata as Spouse of the Holy Spirit

United to the Holy Spirit as his Spouse, the Immaculata is one with God in an incomparably more perfect way than can be predicated of any other creature. What sort of union is this? It is above all an interior union, a union of her essence with the "essence" of the Holy Spirit. The Holy Spirit dwells in her, lives in her. This was true from the fist instant of her existence. It was always true, it will always be true. In what does this life of the Spirit in Mary consist? He himself is uncreated Love in her; the Love of the Father and of the Son, the Love by which God loves Himself, the very love of the Most Holy Trinity. He is a fruitful love, a "Conception". Among creatures made in God's image the union brought about by married love is the most intimate of all (cf. Mt 19:6). In a much more precise, more interior, more essential manner, the Holy Spirit lives in the soul of the Immaculata, in the depths of her very being. He makes her fruitful, from the very first instant of her existence, all during her life, and for all eternity.

The Immaculata's Relationship to the Trinity

From all eternity the Father begets the Son, and the Holy Spirit proceeds from the Father and Son. This life of the most Holy Trinity is re-echoed in numberless and various ways by the creatures that issue from God's hands... Every act of love in God comes forth from the Father through the Son and the Holy Spirit. God creates, maintains in existence, gives life and growth in the natural as well as in the supernatural order. In his love God supports in existence all his innumerable limited created resemblances; and the love-reaction that is provoked in the creature can return to the Father only through the Holy Spirit and the Son... Among creatures, the summit of this love that goes back to God ist the Immaculata, the one being totally with-out any stain of sin, all beautiful, all divine. At no time did her will ever deviate from God's will. With all its strength, her will was always at one with his. In her there came about the marvelous union of God with creation.
