In his homily on 8 December 1978, Pope John Paul II developed the plan of God the Father, our Creator, a plan of love expressed in what is known as a "theology of election". He has chosen man from eternity to share in his own Life. This election takes place in the eternal Son, the Word consubstantial with the Father, through the Incarnation. For the Incarnation, God chose the Virgin Mary to be the Mother of Jesus, His beloved Son.
"God in his eternal love has chosen man from eternity[1]: He has chosen him in his Son.
God has chosen man, in order that he may reach the fullness of good by means of participation in his own life, divine Life, by means of grace.
He chose him irreversibly from eternity.
He has chosen him from eternity, and irreversibly. Neither original sin, nor the whole history of personal faults and social sins have been able to dissuade the eternal Father from this plan of love of his. They have not been able to cancel the choice of us in the eternal Son, the Word consubstantial with the Father.
Since this choice was to take form in the Incarnation, and since the Son of God was to become a man for our salvation, for this very reason the eternal Father chose for him, among men, his Mother. "
