special role of Mary in salvation history is clearly shown in the Gospel where she is seen constantly at her son's side during his soteriological mission. Because of this role, exemplified by her acceptance of Christ into her womb, her offering of him to God at the Temple, her urging him to perform his first miracle, and her standing at the foot of the Cross at Calvary Mary was joined fully in the sacrifice by Christ of himself. Pope Benedict XV wrote in 1918: "To such an extent did Mary suffer and almost die with her suffering and dying Son; to such extent did she surrender her maternal rights over her Son for man's salvation, and immolated him - insofar as she could in order to appease the justice of God, that we might rightly say she redeemed the human race together with Christ." Mary is entitled to the title of Queen because, as Pope Pius XII expressed it in a 1946 radio speech, "Jesus is King throughout all eternity by nature and by right of conquest: through him, with him, and subordinate to him, Mary is Queen by grace, by divine relationship, by right of conquest, and by singular election." Mary possesses a unique relationship with all three Persons of the Trinity, thereby giving her a claim to the title of Queenship. She was chosen by God the Father to be the Mother of his Son; God the Holy Spirit chose her to be his virginal spouse for the Incarnation of the Son; and God the Son chose her to be his mother, the means of incarnating into the world for the purposes of the redemption of humanity. This Queen is also our Mother. While she is not our Mother in the physical sense, she is called a spiritual mother, for she conceives, gives birth, and nurtures the spiritual lives of grace for each person. As Mediatrix of All Graces, she is ever present at the side of each person, giving nourishment and hope, from the moment of spiritual birth at Baptism to the moment of death.
