This study is based on a research I conducted on the integral mission of the Church in the socio-political context of the Republic of Haiti marked by precariousness. The study focuses on the case of Pentecostal churches. The main contribution of this study to the field of contextual theology and missiology is the emergence of a new paradigm of integral mission built around four groups of factors: cognitive, socio-affective, vectorial, and strategic. It is a model of missiology that integrates the evangelical and social mandates of the church into a holistic approach to ministry and provides a framework for linking together, in the implementation of missiological principles, kerygma, koinonia, and diakonia.
