Hermeneutic and Teleology in Ethics across Denominations—Thomas Aquinas and Karl Barth

This study arises from the context of current debates in the Catholic Church on the place of rule and law in moral reasoning. I suggest that ethics may be best served by approaches that place the human subject in a teleogical context and that recognise the need for interpretation of circumstances surrounding actions to be evaluated. This is in contrast to normative rule approaches. The insights retrieved from the account of moral reasoning in Thomas Aquinas by Joseph Selling are compared with an account of the ethical implications of Karl Barth’s theology of hope as expressed in Volume Four of the Church Dogmatics. It is concluded that, in an ecumenical convergence, neither propose a normative rule approach. Rather both use a teleological context and require a hermeneutic of evaluation.
