The United States is in the middle of an unprecedented spiritual, technological, demographic, political and social transformation—moving from an older, mostly white, mostly Protestant, religion-friendly society to a younger diverse, multiethnic, pluralistic culture, where no one faith group will have the advantage. At the same time, millions of Americans are abandoning organized religion altogether in favor of disorganized disbelief. This book is an in-depth and critical look at why people are leaving American churches and what we lose as a society as it continues. But it also accepts the dismantling of what has come before and try to help readers reinvent the path forward.
