\”The august Mother of God, mysterious united from all eternity with Jesus Christ in one and the same decree of predestination, immaculate in her conception, a virgin inviolate in her divine motherhood, the wholehearted companion of the divine Redeemer who won complete victory over sin and its consequences, gained at last the supreme crown of her privileges–to be preserved immune from the corruption of the tomb, and, like her Son, when death had been conquered, to be carried up body and soul to the exalted glory of heaven, there to sit in splendor at the right hand of her Son, the immortal King of the ages.\” –Pope Pius XII, Munificentissimus Deus (1950)
