'At the dawn of the new millennium we notice with joy the emergence of the 'Marian profile' of the Church that summarizes the deepest contents of the conciliar renewal." Pope John Paul II. "In this book the author explores Von Balthasar's vision of Mary and her relevance for the Church...von Balthasar brings us back to the Marian principle of faith and love without which the Petrine principle could not bear fruit. Here is a book which leads us to the heart of the mystery of the Church." John O'Donnell, S.J. Weston School of Theology, Cambridge, Mass.
