George G. Higgins and the Quest for Worker Justice: The Evolution of Catholic Social Thought in America is a comprehensive and fascinating examination of the Catholic Church's involvement in social issues from the late 19th to the end of the 20th century through the lens of the life, career, writings, and ministry of the legendary Monsignor Higgins. Much more than a limited biography, John O' Brien offers a sweeping history of the "social questions" facing America over the past 100 years, the thought behind one of the leading figures in the worker justice movement, and a moving application of the rich heritage of Catholic Social Thought.
