The traditional date of the beginning of the Oriental Schism is 1054. Congar shows that the seeds of this break were sown centuries before when the creation of Byzantium, the Crowning of Charlemagne as Roman Emperor, and emergence of Islam divided East and West politically.

Cardinal Yves Congar is universally known and respected as the great ecclesiologist of Vatican II whose seminal ideas helped to reconfigure the landscape of Catholic theology following the council. Less well known is his role in contributing far-reaching insights to the emerging liturgical movement in the church. This collection represents several of Congar's decisive contributions. Reading them makes possible a deeper and more cogent reception of the key ideas of the council documents. These texts are at once both erudite and exciting, both essential and pastorally incisive. There has never been a better time to disseminate these critically important liturgical insights than the present moment.

"Cardinal Yves Congar, OP, who died in 1995, was a French Dominican widely recognized as one of the most important Roman Catholic theologians of the twentieth century and a major influence upon the theology of the documents of Vatican II. Congar drew from biblical, patristic, and medieval sources to revitalize the discipline of contemporary theology. He was an early advocate of ecumenism and also contributed to shaping the theological agenda of the twentieth-century liturgical movement."

"Pal Philibert, OP, is a retired professor of pastoral theology who has taught in the United States and abroad. He is a Dominican friar of the US Southern Province. His 2005 Liturgical Press book, "The Priesthood of the Faithful: Key to a living Church, " reflects the theology of these essays of Cardinal Yves Congar. His translation of Congar's masterpiece, "True and False Reform in the Church, "will soon be published by Liturgical Press."

Written as a young man in Sedan, in eastern France, which was occupied by the Germans in the First Wold War, Congar makes daily entries about the War. Written from the eyes of a child, the diary was found in his room in Paris after his death and published a few years later. The diary comes with the drawings, maps, and poetry he made as part of this daily entries.

A series of articles by Yves Congar from 1946 to 1956. Yves Congar kept, in a discontinuous way, a journal on the main events of the life of the church with which he was involved in this period, either directly or indirectly. He assembled these writings which constitute a living chronicle and informs the reader about the history of the intellectual life of the Catholic Church after the Second World War. Fresh out of captivity after the War he was under suspicion and sanctions by ecclesial authorities for some of his writings. The journal details this ordeal, and is an exceptional document on the relationship between theological research and Roman magisterium at the end of the pontificate of Pius XII.

Yves Congar was the most significant voice in Catholic pneumatology in the twentieth century. This new collection of short pieces makes his thought accessible to a broad range of readers - scholars, teachers, ecumenists and laity - and thus helps to ensure that an important theological voice, one that influenced many of the documents of the Second Vatican Council, continues to be heard. The Spirit of God brings together for the first time eight of Yves Congar's previously untranslated writings on the Holy Spirit composed after Vatican II (from 1969 to 1985). Two of these selections offer general overviews of Congar's pneumatology, a pneumatology based upon Scripture and the Tradition of the Church, but articulated in conversation with philosophers, ecumenical partners and non-believers. Other articles make clear the historical context of Vatican II's pneumatology and the Holy Spirit's crucial influence upon the unfolding of history and upon the moral life, the efficacy of the sacraments and, especially, upon ecclesial life. The writings in The Spirit of God have been translated and edited by a team of scholars familiar with the work of the French Dominican theologian. An introduction situates each of the writings historically and highlights its theological significance. A bibliography lists Congar's publications on the Holy Spirit, the major articles and books written about his pneumatology, and the major scholarly resources to which Congar made reference in the notes that accompanied these writings. An index of biblical references and of personal names is also included.

Archbishop Angelo Roncali (later Pope John XXIII) read "True and False Reform" during his years as papal nuncio in France and asked, A reform of the church 'is such a thing really possible?" A decade later as pope, he opened the Second Vatican Council by describing its goals in terms that reflected Congar's description of authentic reform: reform that penetrates to the heart of doctrine as a message of salvation for the whole of humanity, that retrieves the meaning of prophecy in a living church, and that is deeply rooted in history rather than superficially related to the apostolic tradition. Pope John called the council not to reform heresy or to denounce errors but to update the church's capacity to explain itself to the world and to revitalize ecclesial life in al its unique local manifestations. Congar's masterpiece fills in the blanks of what we have been missing in our reception of the council and its call to "true reform."

"Yves Congar, OP, a French Dominican who died in 1995, was the most important ecclesiologist in modern times. His writings and his active participation in Vatican II had an immense influence upon the council documents. With a few other contemporaries, Congar pioneered a new style of theological research and writing that linked the great tradition of Scripture and the Fathers to contemporary pastoral questions with lucidity and passion. His key concerns were the unity of the church, lay apostolic life, and a revival of the church's theology of the Holy Spirit. He was named a cardinal by Pope John Paul II in recognition of his profound contributions to the Second Vatican Council.""Pal Philibert, OP, has taught pastoral theology in the United States and abroad. He is a Dominican friar of the Southern Province. His translation of a collection of Congar's essays on the liturgy has recently been published by Liturgical Press under the title "At the Heart of Christian Worship." His book "The Priesthood of the Faithful: Key to a living Church" (Liturgical Press, 2005) reflects the ecclesiology of Yves Congar and his Vision of the apostolic life of the faithful.""
