"Ecumenism: A Guide for the Perplexed" is a comprehensive introduction to the methods, achievements, and future prospects of the modern ecumenical movement. The authors begin the volume by charting out a serviceable definition of ecumenism, a term that has long been a source of confusion for students of theology and church history. A concise review the chronology of the first century of the modern ecumenical movement is then offered, which highlights the major events, figures, accomplishments, and impasses. This historical survey is followed by critical examinations of several significant challenges for contemporary ecumenical theology and practice. The conclusion is a commentary upon the difficulties and prospects that the ecumenical movement might anticipate as it enters this new millennium.
