Rev. Dr. Eileen Lindner's seminar "By the Numbers: A Quantitative Look at the American Religious Landscape" at the 2012 National Workshop on Christian Unity on April 17, 2012. Changing patterns of church membership gains and losses, seminary enrollments and the emergence of new church groups have altered the long dominant face of American Christianity. Growing religious pluralism and increasing secularism have likewise contributed to a substantial reconfiguration of the American religious landscape. The workshop charted these and gave special attention to the ways in which church institutional life is adapting within the American context. Dr. Lindner is editor of the "Yearbook of American and Canadian Churches."
