Book excerpt: The Pentecostal movement has been subject to some negative external assumptions. In this enlightening and challenging book, Cheryl Bridges Johns argues that, in fact, Pentecostals employ a powerful process of formation of catechesis, which has enabled millions of believers to own and articulate the Christian story. She engages dialectically with the work of Paulo Freire, a specialist in education among the marginalized. As well as looking more broadly at the nature of all catechesis, there is also an attempt to move beyond the rationalism found in a praxis epistemology.
