102. At the end of this Encyclical, we naturally look again to the Lord Jesus, "the Child born for us" (cf. Is 9:6), that in him we may contemplate "the Life" which "was made manifest" (1 Jn 1:2). In the mystery of Christ's Birth the encounter of God with man takes place and the earthly journey of the Son of God begins, a journey which will culminate in the gift of his life on the Cross. By his death Christ will conquer death and become for all humanity the source of new life.
The one who accepted "Life" in the name of all and for the sake of all was Mary, the Virgin Mother; she is thus most closely and personally associated with the Gospel of life. Mary's consent at the Annunciation and her motherhood stand at the very beginning of the mystery of life which Christ came to bestow on humanity (cf. Jn 10:10). Through her acceptance and loving care for the life of the Incarnate Word, human life has been rescued from condemnation to final and eternal death.
For this reason, Mary, "like the Church of which she is the type, is a mother of all who are reborn to life. She is in fact the mother of the Life by which everyone lives, and when she brought it forth from herself she in some way brought to rebirth all those who were to live by that Life".138
As the Church contemplates Mary's motherhood, she discovers the meaning of her own motherhood and the way in which she is called to express it. At the same time, the Church's experience of motherhood leads to a most profound understanding of Mary's experience as the incomparable model of how life should be welcomed and cared for.
