One of the major figures of 20th century Catholic theology, Henri Cardinal de Lubac SJ was particularly renowned for his attention to the doctrine of the Church and its life within the contemporary world. In this book, de Lubac opens an initial exploration of the Church as made by the Eucharist and gives new expression to that mystery in which the Church is believed to consist. As one whose generous and fervent spirit contributed significantly to the thinking of the Second Vatican Council, de Lubac’s influence has been widespread, making a substantial impact also on the development of ecumenical relations between Catholic, Protestant and Orthodox theologians. With the publication of this English translation of Corpus Mysticum, this important text of contemporary Catholic ecclesiology and sacramental theology is made available to the Anglophone world and joins the substantial range of de Lubac’s works now accessible to scholars.
