48 It is precisely the special bond between humanity and this Mother which has led me to proclaim a Marian Year in the Church, in this period before the end of the Second Millennium since Christ's birth, a similar initiative was taken in the past. when Pius XII proclaimed 1954 as a Marian Year, in order to highlight the exceptional holiness of the Mother of Christ as expressed in the mysteries of her Immaculate Conception (defined exactly a century before) and of her Assumption into heaven. Now, following the line of the Second Vatican Council, I wish to emphasize the special presence of the Mother of God in the mystery of Christ and his Church. For this is a fundamental dimension emerging from the Mariology of the Council, the end of which is now more than twenty years behind us. The Extraordinary Synod of Bishops held in 1985 exhorted everyone to follow faithfully the teaching and guidelines of the Council We can say that these two events-the Council and the synod-embody what the Holy Spirit himself wishes "to say to the Church" in the present phase of history. In this context, the Marian Year is meant to promote a new and more careful reading of what the Council said about the Blessed Virgin Mary, Mother of God, in the mystery of Christ and of the Church, the topic to which the contents of this Encyclical are devoted. Here we speak not only of the doctrine of faith but also of the life of faith, and thus of authentic "Marian spirituality," seen in the light of Tradition, and especially the spirituality to which the Council exhorts us. Furthermore, Marian spirituality, like its corresponding devotion, finds a very rich source in the historical experience of individuals and of the various Christian communities present among the different peoples and nations of the world. In this regard, I would like to recall, among the many witnesses and teachers of this spirituality, the figure of Saint Louis Marie Grignion de Montfort, who proposes consecration to Christ through the hands of Mary, as an effective means for Christians to live faithfully their baptismal commitments. I am pleased to note that in our own time too new manifestations of this spirituality and devotion are not lacking. There thus exist solid points of reference to look to and follow in the context of this Marian Year.
