David N. Livingstone and Ronald A. Wells are scholars interested in the cultural and social location of ideas. Their transatlantic religious and cultural history explores the connection between Presbyterianism in Northern Ireland and the United States over the last 150 years. They identify religious ideologies and practices in their various forms during this period, and situate them culturally. By observing how context shapes and interprets the Presbyterian religion and culture in Ulster and America, they reveal the way in which intellectual and cultural meanings of religious belief change over time.
