Mark Chaves looks at trends in diversity, belief, involvement, congregational life, leadership, liberal Protestant decline, and polarization. He draws on two important surveys: the General Social Survey, an ongoing survey of Americans' changing attitudes and behaviors, begun in 1972; and the National Congregations Study, a survey of American religious congregations across the religious spectrum. Chaves finds that American religious life has seen much continuity in recent decades, but also much change. He challenges the popular notion that religion is witnessing a resurgence in the United States--in fact, traditional belief and practice is either stable or declining. Chaves examines why the decline in liberal Protestant denominations has been accompanied by the spread of liberal Protestant attitudes about religious and social tolerance, how confidence in religious institutions has declined more than confidence in secular institutions, and a host of other crucial trends.
