A Moving Faith captures the dynamic shift of Christianity to the South and portrays a global movement that promises prosperity, healing, empowerment, and gender equality by invoking neo-Pentecostal and Charismatic resources. It postulates that neither North America nor Europe is the current center of the Christian faith.

The book provides a detailed overview of how migration of Christians from the South enriches the North, for instance, Pope Francis brings newness, freshness, and the vigor characteristic of the South. While describing Christianity's growth in the South, it suggests that, in fact, there is no center for this global faith. It explores this great move of Christianity by focusing on representative mega churches in South Korea, Brazil, Peru, Ghana, Nigeria, Australia, India, and the Philippines.
