Pentecostalism is the fastest-growing segment of global Christianity, representing at least a quarter of the world’s 2 billion Christians. As the evangelical movement spreads, it is bumping up against established religions like Islam in Africa and Roman Catholicism in Latin America. In this meeting, part of the Council’s Nexus of Religion and Foreign Policy initiative, Luis Lugo and Walter Mead discuss the rapid growth of this movement and what it portends for U.S. foreign policy as well as international relations throughout the world.
