44 Given Mary's relationship to the Church as an exemplar, the Church is close to her and seeks to become like her: "Imitating the Mother of her Lord, and by the power of the Holy Spirit, she preserves with virginal purity an integral faith, a firm hope, and a sincere charity." Mary is thus present in the mystery of the Church as a model. But the Church's mystery also consists in generating people to a new and immortal life: this is her motherhood in the Holy Spirit. And here Mary is not only the model and figure of the Church; she is much more. For, "with maternal love she cooperates in the birth and development" of the sons and daughters of Mother Church. The Church's motherhood is accomplished not only according to the model and figure of the Mother of God but also with her "cooperation." The Church draws abundantly from this cooperation, that is to say from the maternal mediation which is characteristic of Mary, insofar as already on earth she cooperated in the rebirth and development of the Church's sons and daughters, as the Mother of that Son whom the Father "placed as the first-born among many brethren." She cooperated, as the Second Vatican Council teaches, with a maternal love. Here we perceive the real value of the words spoken by Jesus to his Mother at the hour of the Cross: "Woman, behold your son" and to the disciple: "Behold your mother" (Jn. 19:26-27). They are words which determine Mary's place in the life of Christ's disciples and they express-as I have already said-the new motherhood of the Mother of the Redeemer: a spiritual motherhood, born from the heart of the Paschal Mystery of the Redeemer of the world. It is a motherhood in the order of grace, for it implores the gift of the Spirit, who raises up the new children of God, redeems through the sacrifice of Christ that Spirit whom Mary too, together with the Church, received on the day of Pentecost. Her motherhood is particularly noted and experienced by the Christian people at the Sacred Banquet-the liturgical celebration of the mystery of the Redemption-at which Christ, his true body born of the Virgin Mary, becomes present. The piety of the Christian people has always very rightly sensed a profound link between devotion to the Blessed Virgin and worship of the Eucharist: this is a fact that can be seen in the liturgy of both the West and the East, in the traditions of the Religious Families, in the modern movements of spirituality, including those for youth, and in the pastoral practice of the Marian Shrines. Mary guides the faithful to the Eucharist.
