Devotion to Mary has always been one of the defining characteristics of being a Catholic. Marian feasts, prayers, hymns, places of pilgrimage make up the very fabric of a lived Catholic Faith. Dr Francesca Murphy explores Mary's unique role in the incarnation and how it has always assisted the Church in avoiding theological error. She also explains the art of saying the rosary and how it has helped both the learned and the simple throughout its history to know Christ better.
