This course—the first at YDS to focus on digital cultures—enquires into ecclesial practices that have migrated online and are digitally mediated, especially those of prayer and worship. In recent years, both very old and entirely new liturgical practices have flourished in digital social space, from the live streaming of worship services to digital prayer chapels, virtual choirs, online pilgrimages, and digitally mediated devotions such as daily prayer via tweets or “pray-as-you-go” apps. Some communities have experimented with so-called cyber-baptisms and cyber-communions. And cyberspace hosts communities of faith that exist only online, for example, in Web-based interactive virtual reality environments. This course brings the tools and insights of new media theories, liturgical studies, and constructive theology to the enquiry into these ecclesial practices. Area II.
