Perhaps there are some who fear that the Rosary is somehow unecumenical because of its distinctly Marian character. Yet the Rosary clearly belongs to the kind of veneration of the Mother of God described by the [Second Vatican] Council: a devotion directed to the Christological centre of the Christian faith, in such a way that "when the Mother is honoured, the Son ... is duly known, loved and glorified." (Lumen Gentium #66) If properly revitalized, the Rosary is an aid and certainly not a hindrance to ecumenism! (Rosarium Virginis Mariae, #4)The Holy Father’s words troubled me then, as they do now. In my lived experience, Marian…“anything” in an ecumenical context is far more likely to present differences over similarities, or even harden well-defined perspectives, than prompt ideas about growing together in Christian love. No one is neutral, it seems, when it comes to describing their relationship to the Mother of God. At the root of Christian agreements and disagreements about Mary are matters that are at the same time biblical, doctrinal, historical, liturgical, theological, sociological, soteriological, ecclesiological, and so on. What does the Bible say or not say about Mary, and how is this to be interpreted? How much of what is professed about Mary belongs to the Tradition of the Church rather than directly found in Scripture? How much is from historical, cultural, or sentimental expressions developed within specific churches? Does Marian doctrine or devotion enhance or take away anything from the central focus on Christ? What is the relationship between God’s grace present and active in Mary’s life, and her own (and our own) human actions or belief? What is meant by the veneration of Mary (or of the saints) as distinct from worshipping God? When and by whose authority did Marian titles, feasts, and dogmas come to be assigned within the Christian Church? Are all such titles, feasts, and dogmas essential, obligatory, and/or intended to be marked with equal solemnity? How is Mary’s life and faith presented as a model for female Christian discipleship, or as exemplary for Christian life in general? Such questions (and this is by no means an exhaustive list) touch upon the foundations of the Christian faith, and form the very fabric of denominational identities. As these questions come to be posed, interpreted, and answered, it becomes clear why discussions about Mary are never neutral: they open up everything else, and become necessarily important as a reflection and manifestation of the “what” and “how” of basic Christian belief. What, then, is the future of Mary, ecumenically-speaking? Is she forever destined to be the “Mother of Christian Disunity”? It is encouraging to note that considerable progress is being made through international and national ecumenical dialogue groups, and by numerous theologians from across the Christian spectrum, toward a common understanding of the role of Mary in salvation history. Here are some highlights:
