6 All this is accomplished in a great historical process, comparable "to a journey." The pilgrimage of faith indicates the interior history, that is, the story of souls. But it is also the story of all human beings, subject here on earth to transitoriness, and part of the historical dimension. In the following reflections we wish to concentrate first of all on the present, which in itself is not yet history, but which nevertheless is constantly forming it, also in the sense of the history of salvation. Here there opens up a broad prospect, within which the Blessed Virgin Mary continues to "go before" the People of God. Her exceptional pilgrimage of faith represents a constant point of reference for the Church, for individuals and for communities, for peoples and nations and, in a sense, for all humanity. It is indeed difficult to encompass and measure its range. The Council emphasizes that the Mother of God is already the eschatological fulfillment of the Church: "In the most holy Virgin the Church has already reached that perfection whereby she exists without spot or wrinkle (cf. Eph. 5:27)"; and at the same time the Council says that "the followers of Christ still strive to increase in holiness by conquering sin, and so they raise their eyes to Mary, who shines forth to the whole community of the elect as a model of the virtues." The pilgrimage of faith no longer belongs to the Mother of the Son of God: glorified at the side of her Son in heaven, Mary has already crossed the threshold between faith and that vision which is "face to face" (1 Cor. 13:12). At the same time, however, in this eschatological fulfillment, Mary does not cease to be the "Star of the Sea" (Maris Stella) for all those who are still on the journey of faith. If they lift their eyes to her from their earthly existence, they do so because "the Son whom she brought forth is he whom God placed as the first-born among many brethren (Rom. 8:29)," and also because "in the birth and development" of these brothers and sisters "she cooperates with a maternal love."
