The second Vatican Council says, "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 liturgy is the summit toward which the activity of the Church is directed; 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. He compellingly shows us the biblical, historical, and theological dimensions of the Eucharist. The Cardinal draws far-reaching conclusion, 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, now Benedict XVI, the transformation of the world on the social plane grows out of the celebration of the Eucharist. He beautifully illustrates how the omnipotent God comes intimately close to us in the Holy Eucharist, the Heart of Life.
