"The purpose of this book is primarily to provide a comprehensive reference and source of information for those who labour daily in the churches and organizations that make up the ecumenical movement. It is hoped that, beyond that circle, the book will also serve all who have a passion for, or an interest in the movement. A Handbook of Churches and Councils – Profiles of Ecumenical Relationships replaces two earlier publications: the Handbook of WCC Member Churches, and the Directory of Christian Councils, both dating back to 1985."
