That Evangelicalism is the fastest growing brand of Christianity in Africa is not disputed. While studies on Evangelicalism in Africa has tended to focus on beliefs, it needs to be noted that Evangelicalism in Africa is far more about what it does to and for its followers than about what kinds of beliefs it promotes. It is in this regard that African Evangelicalism has not been keen to propagate Creedal Christianity in its praxis, even though the same shines in its theology. This paper argues that African Evangelical Theology, while maintaining the Creedal ethos, emphasises orthopraxy over orthodox theological dogmas or proportionalism. The main issue for African Evangelicalism, is how theology can address the myriad of challenges facing the people. This paper points out that African Evangelical Theology goes beyond its rootedness in Creedal doctrines, to theological functionalism: examining the functions and purposes of Christian theological beliefs and practices within the African society. The functionalism proposed in this paper is premised on Evangelical hermeneutics, culminating in a practical theology evidenced through mission, ministry, and the life of the Church.
