Abstract: The issues of manipulation, control, and ‘forced giving’ in the Church context have raised a lot of concern and especially at a time when the moral authority of the Church has been questioned. Indeed, in the wake of the evangelical explosion, con preachers and fake miracle workers have infiltrated and polluted the good news of the gospel. This study aimed at investigating whether spiritual control did exist in the Pentecostal Church setting, and if so, then the effect it has on the performance of Pentecostal churches in Nairobi County, Kenya. The research used a mixed methods design, embracing a concurrent triangulation strategy, and assuming a pragmatic philosophical approach. The target population was the 12891 congregants in the Pentecostal congregations in Embakasi East Sub-County, Nairobi County.
