With this book, Michael Mahony introduces his Trilogy on the Eucharist. His objectives in this present volume include exposing a wider Christian audience to the Framework and Theology of the Eucharist, and to the role which the Eucharist plays in God's plan to sustain the Church over time, not least in our present age of "The Runaway Church". At the same time, he challenges Catholic readers to take a fresh look at the much neglected Concluding Rites of the Eucharist, claiming that the link therein between the Eucharist and the Kerygma is central to achieving the purposes of the New Evangelization, particularly with regard to the laity's role in such evangelization. This is the fifth in a collection of seven books which are one ordinary person's exploration of the relationship between God and the human race, centered around the revelation of Jesus Christ who became One of Us in order that humanity could, in turn, share in the life within God.
