A few years ago, while reading "Christ the Savior" by Fr. Reginald Garrigou-Lagrange, O.P. on the Assumption of the B.V.M., I came across the following passage:
Therefore the Blessed Virgin Mary, as Mother of the Savior and the new Eve, is also most closely associated with Christ's perfect victory over death, so that "she could not be held down or detained by the bonds of death, " as the liturgy says[19]; otherwise she would have been vanquished by death and would not have been the vanquisher, and her parallelism with Christ's resurrection and ascension, before the general resurrection of the dead, would be destroyed. Moreover, the exceptional benediction, "blessed art thou among women," excludes the malediction "into dust thou shalt return." (emphasis mine)
