This book features findings from a new research project with this surprising conclusion: It's time to replace lament over problems facing twenty-first-century mainline churches with aspirations of hope and possibilities for health. Core beliefs about hope and guidelines for making hope happen are introduced. Eighteen models of healthy congregations over four decades are highlighted—some research-based, others denomination-based or book-based. Markers of flourishing congregations are derived from these models. A new 4 C's relational approach to congregational health is offered centered in community, communication, character, and collaboration. Twenty-four practical ways these four signs of health are exemplified are drawn from the latest social and relationship science research. The research project tests the validity and usefulness of the core beliefs about hope, the markers of flourishing congregations, and the new relational approach to congregational health. You'll also find guidelines for creating more hope-filled and healthy futures for mainline churches.
