<DIV><P> One of the major figures of twentieth-century Catholic theology, Henri Cardinal de Lubac was known for his attention to the doctrine of the church and its life within the contemporary world. In <I>Corpus Mysticum </i>de Lubac investigates a particular understanding of the relation of the church to the eucharist. He sets out the nature of the church as communion, a doctrine that influenced the thinking of the Second Vatican Council.</P><p> With the publication of <I>Corpus Mysticum</i>, this important text of contemporary Catholic ecclesiology and sacramental theology is available for the first time in an English translation. Its publication fills a significant gap in the range of de Lubac's works available to English-speaking scholars. It will be an important resource in the widespread and ongoing ecumenical discussions among Catholic, Protestant, and Orthodox theologians.</P><p> His Eminence<B> Henri Cardinal de Lubac, SJ </B>(1896?1991), a French Jesuit, is considered to be one of the most influential theologians of the twentieth century. He is the author of a number of books, including <I>Catholicism and Theology in History</i>.</P><p> <B>Gemma Simmonds CJ </B>is lecturer at Heythrop College, University of London. Richard Price is Lecturer at Heythrop College, University of London.</P><p> "This translation of <I>Corpus Mysticum</i> is a gift to medieval historians, liturgists, ecclesiologists, and any Christian interested in a profoundly prophetic reading of one of the central mysteries of her or his religion. This is one of a very few books that has formed our present consciousness of who we are as Catholics and Christians. To preserve access to it will significantly aid our attempts to move into a future to some extent already foreshadowed in de Lubac's study of the past." ?<B>Gary Macy, University of San Diego</B></P></DIV>
