This work introduces an Epistemological model that I have developed to examine truth claims and belief statements. I have called the model the Existential, Eventoriented and Ideological (EEI) Justification Model. The model is based on specific criteria of truth examined in the research. I developed this model as I saw the need for the evangelical community to address two main challenges they have to face in post-apartheid urban South Africa; moral relativism and the South African indigenous theology practiced by many of the African Indigenous Church groups. This research demonstrates how the Existential, Event-oriented and Ideological (EEI) justification model can be used to address these challenges facing the evangelical community in post-apartheid urban South Africa.
