Sources of bioethics: <i>Lex Naturae</i> versus <i>Sola Scriptura</i> and <i>Sola Gratia</i>? A response to Vorster

To argue that the concept of natural law can be regarded, with certain conditions, as a credible and useful tool in the Reformed paradigm, as Vorster did, may at first seems to be in conflict with the Reformation’s emphasis on sola scriptura and sola gratia. Vorster, however, argues very convincingly that the general revelation of God and creational gifts can be a source for bioethics within the reformed tradition. He does this by relying on Calvin and Bavinck’s appreciative theologies and in reaction to Barth and Welker’s critique to the notion of natural law. In this article I will further Vorster’s argument by identifying some critical points in his argument, analyse the critique on these points and broaden the discussion by incorporating an eschatological perspective and the anthropology of the Protestant philosopher, Paul Ricoeur. The aim is, as Vorster states in his conclusion, to provide Christian ethics with opportunities and means to formulate applicable and relevant moral codes that can be utilised in the bio- and eco-ethical debates of today.
