This quote in particular struck me:
"We may say to the compassionate heart of Mary standing at the foot of the cross (Jn. 19:25) what St. John Damascene said to the Virgin of the Annunciation: Be joyful! You are the ewe giving birth to the Lamb of God, you are the instrument of our salvation". Emphasis mine.
Salvific power is definately a divine attribute.

If Mary had said no, Christ would not have come. Her "fiat" was the predicate to Christ's Incarnation. God forces the hand of no man (or woman). That being said, her 'fiat' made her the instrument of salvation, because her agreement was necessary for the incarnation to occur. Christ came to save us by being born of Mary.
