Book excerpt: According to the Second Vatican Council, "We ought to try to discover a new reverence for the Eucharistic mystery. Something is happening that is greater than anything we can do. The magnitude of what is happening is not dependent on the way we perform it, but all our efforts to perform it aright can always be at the service of the great act that precedes our own and that we cannot achieve for ourselves... The liturgy is the summit toward which the activity of the Church is directed; at the same time it is the font from which all her power flows." This profound statement about the Eucharist stands at the center of this book by Cardinal Ratzinger. In these previously unpublished texts, the Prefect of the Congregation for the Doctrine of the Faith and a scholar of international repute, leads the reader into the heart of the Christian faith and its central mystery. Cardinal Ratzinger compellingly shows us the biblical, historical, and theological dimensions of the Eucharist. The Cardinal draws far-reaching conclusions, focusing on the importance of one's personal devotion to and adoration of the Blessed Sacrament, for the personal reception of Communion by the individual Christian, as well as for the life of the Church. For Ratzinger, the drive toward any transformation of the world on the social plane also grows out of the celebration of the Eucharist. He beautifully illustrates how the omnipotent God and Creator comes intimately close to us in the Holy Eucharist, the Heart of Life. Book jacket.
