If we are to understand the Eucharist as the Body of Christ, it is necessary to explore how Mary’s own body participates in the Eucharistic mystery. Such a discussion was prominent during the Middle Ages, but today there is very little attention given to the relationship between Mary and the the Eucharist.

This paper will explore this subject through the lens of a theology of the sacramental principle. By examining recent papal documents as well as John Paul II’s Theology of the Body, this paper will argue that Mary is the perfect fulfilment of the sacramental principle. The sacramental principle fulfilled is a principle that is nuptial, where the Eucharist expresses the wedding point between God and creation. It is Mary who unveils this mystery in her own person and body.
