This work is an excellent study of lived theology. In Björkander’s analysis, the theological riches of Pentecostal spirituality come to the fore. - Mika Vähäkangas, Professor, Director of Polin Institute of Åbo Akademi University Björkander here makes a significant contribution to a pentecostal theology of worship that accounts for the various affective, performative, and embodied dimensions of pentecostal spirituality, enabled through meticulous ethnographic foregrounding of two charismatic East African congregations and their ritual practice. This is practical theology at its best, lifting up the many (disciplinary) tongues and (linguistic) accents of global pentecostal-charismatic Christianity. - Amos Yong, Professor of Theology and Mission, Fuller Seminary
