"The trees were passive to Orpheus; that's why they danced"

"the crucial point to observe here is that Mary is judged to have been purely receptive in relation to God and to God's reconciling purposes.  And yet, her receptivity is to be understood as active, not passive.  She 'goes forth to receive the Lord.'  And that is a point of considerable significance.  Emphasis is laid here on the active obedience of Mary, on her (human) power to receive the Holy Spirit rooted in her holiness.  To be sure, the 'person-forming' power (if I can again borrow a Christological caegory) remains God's.  Mary is given the power of 'Divine Maternity.'  She 'becomes heaven, and Her womb becomes the place of the overshadowing.'  Indeed, what she receives in her virginal conception is not a gift of grace so much as it is 'the Holy Spirit Himself in all the fullness of His divine nature.'  And so she was made the fit instrument of the incarnation of the Logos.  But she must voluntarily receive for any of this to happen.  A hierarchy of wills is envisioned; the lesser 'follows' the greater.  The same holds true in the hypostatic union itself - which brings us, in the second place, to Jesus."
