Multifaith initiatives have been increasingly implemented to counter global risks—such as terrorism and climate change—and advance common security in Western societies. This paper examines the rise of multifaith engagement in the twenty-rst century, drawing on 42 semi-structured interviews with leading multifaith practitioners in Australia, the United Kingdom and the United States of America. Building upon Brodeur’s (2005) typology, I identify four principal aims and six characteristics of the multifaith movement. In addition, I propose a new theoretical framework that I term netpeace, which recognises the interconnectedness of global problems and solutions and the capacity of multi-actor peacebuilding networks—including religious actors—to collaboratively overcome the most pressing risks of our times.
