Beginning with the legacy of Roger Williams, who in 1633 founded the first colony not restricted to people of one faith, The Lively Experiment chronicles how Americans have continually demolished traditional prejudices while at the same time erecting new walls between belief systems. The chapters gathered here reveal how Americans are sensitively attuned to irony and contradiction, to unanticipated eruptions of bigotry and unheralded acts of decency, and to the disruption caused by new movements and the reassurance supplied by old divisions. The authors examine the way ethnicity, race, and imperialism have been woven into the fabric of interreligious relations and highlight how currents of tolerance and intolerance have rippled in multiple directions. Nearly four hundred years after Roger Williams Rhode Island colony, the lively experiment of religious tolerance remains a core tenet of the American way of life. This volume honors this boisterous tradition by offering the first comprehensive account of America’s vibrant and often tumultuous history of interreligious relations.
