This is a title, Venerable Brothers, not new to Christian piety; it is precisely by this title, in preference to all others, that the faithful and the Church address Mary. It truly is part of the genuine substance of devotion to Mary, finding its justification in the very dignity of the Mother of the Word Incarnate. Just as, in fact, the Divine Maternity is the basis for her special relationship with Christ, and for her presence in the economy of salvation brought about by Jesus Christ, thus it also constitutes the principal basis for the relations between Mary and the Church, since she is the mother of him who, right from the time of his Incarnation in her virginal bosom, joined to himself as head of his Mystical Body which is the Church. Mary, then as Mother of Christ, is mother also of all the faithful and of all the Pastors. We trust then, that with the Promulgation of the Constitution on the Church, sealed by the Proclamation of Mary as Mother of the Church, that is to say of all the faithful and all the Pastors, the Christian people may, with greater ardor, turn to the Holy Virgin and render to her the honor and devotion due to her. ( ...) Just as at the invitation of Pope John XXIII We entered the Council hall, along with "Mary, the Mother of Jesus," so at the close of the third session We leave this Temple with the most holy and sweet name of Mary, Mother of the Church.
