Mary can be said to continue to say to each individual the words which she spoke at Cana in Galilee: "Do whatever he tells you." For he, Christ, is the one Mediator between God and mankind; he is "the way, and the truth, and the life" (Jn. 14:6); it is he whom the Father has given to the world, so that man "should not perish but have eternal life" (Jn. 3:16). The Virgin of Nazareth became the first "witness" of this saving love of the Father, and she also wishes to remain its humble handmaid always and everywhere. For every Christian, for every human being, Mary is the one who first "believed," and precisely with her faith as Spouse and Mother she wishes to act upon all those who entrust themselves to her as her children. And it is well known that the more her children persevere and progress in this attitude, the nearer Mary leads them to the "unsearchable riches of Christ"(Eph. 3:8). And to the same degree they recognize more and more clearly the dignity of man in all its fullness and the definitive meaning of his vocation, for "Christ...fully reveals man to man himself."
