Mary is not alone in presenting a challenge to theology. The Church still struggles to express an adequate theology of the Holy Spirit, yet there can be no doubt about the Spirit’s presence in the life of Christ and in the lives of all believers. To different degrees the same could be said of all the central doctrines of Christian faith, not least the Trinity. Our theological articulation of the significance of Mary and her role within the Church and the lives of Christians always seems to follow our devotional practice. This should not really surprise us: often the truth of faith does not first come in a concept or a thought but in an experience, an insight or encounter, and this produces its own form of language, symbol and gesture. It’s the difference between trying to map the moves of a ballet on paper and seeing it executed on stage. Imagine music if we only had the score and no sound.
