This book is a celebration of the one-hundred-year history of the Week of Prayer for Christian Unity and a wonderful resource for understanding the theology and practice of common prayer for the reconciliation of the churches. Contributors to this volume represent a cross-section of perspectives both denominationally including Anglican, Roman Catholic, Baptist, and Reformed as well as in light of their lived experience of Christian spirituality and prayer. Each essayist offers significant insights into the history, theology, and spirituality of the Week of Prayer in particular, and of ecumenical prayer in general. / Contributors: Catherine Clifford, Sr. Minke de Vries, Steven R. Harmon, Walter Cardinal Kasper, James Puglisi, Charles Sherlock, George Tavard.
