Within global evangelicalism the historical discipline within missiology known as ‘elenctics’ (to ‘convict’ or ‘unmask’ sin) deserves to be revived and reflected upon in the apologetic and missionary task both in Western and non-Western contexts. While mentioned favourably by the likes of John Stott and David Hesselgrave, elenctics’ champion has been the twentieth century Dutch Reformed missiologist J.H. Bavinck (1895-1964). His work has seen something of a resurgence of late, so elenctics has a good platform to make its case. In this paper, I will define and describe elenctics before focusing on a number of areas that need further investigation within the discipline. The first is a recognition of the New Testament uses of the ‘elengho’ verb not often referenced in the discussion of elenctics, in particular 1 Cor. 14:24 which helps in our understanding of the elenctic task. The second is to further press into the issue raised recently by missiologist Chris Flanders et al. concerning whether the focus of elenctics should be that of primarily the uncovering of guilt or that of shame. The guilt/shame discussion is a longstanding one within global evangelicalism but perhaps the study of elenctics can shed some new light on what is often a heated debate. Finally, I will try and relate ‘elenctics’ to the contemporary discipline of cultural apologetics in particular the model that uses the framework used by Strange, Keller et al. known as ‘subversive fulfilment’.
