Ecumenism: A Guide for the Perplexed [PDF ebook] 

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. They review the chronology of the modern ecumenical movement and highlight the major events, figures, accomplishments, and impasses. This historical survey is followed by critical examinations of three significant challenges for contemporary ecumenical theology and practice. Along the way, the authors provide commentary upon the difficulties and prospects that the ecumenical movement might anticipate as it enters this new millennium.
