Some of the New Prophetic Churches apply the fundamentalist literalist reading of the biblical text in their sermons and theology because of a lack of knowledge and application of proper reading and interpretation of scripture. The fundamentalist literalist reading of scripture particularly Mark 16:18 is linked here to the abuses by some of the pastors in New Prophetic Churches. In addressing these challenges, this article proposes a proper exegetical study of Mark 16:18 that pays attention to the context of the text, the historical background and the grammar of the text. This will be achieved by giving a background to a fundamentalist literalist reading of scripture in Pentecostalism particularly as practised by New Prophetic Churches in South Africa. The article will also highlight some of the challenges posed by the fundamentalist literalist reading of scripture. The final section is an exegetical study of Mark 16:18, which is interpreted by recognising the whole passage of Mark 16:9–20 even though some New Testament scholars do not recognise this longer ending. This article reflected on this passage in response to the fundamentalist literalist reading among New Prophetic Churches not necessarily to enter the debate between the short ending and longer ending.Contribution: This article challenges fundamentalist literalist reading of scripture in New Prophetic Churches. The article proposes a thorough exegetical reading of Mark 16:18 that recognises the exegetical tools such as history, grammar and the context of the text.
