Abstract

In recent years, Karl Rahner's theology of concupiscence as a «pre-ethical appetite» has been subjected to some negative criticism as «un-Thomistic» and as presupposing modern philosophy's dualistic understanding of being. The present essay tries to situate Rahner's interpretation within the theological context of the time when it was originally published; the major debate then was on the nature of the supernatural and the desiderium naturale videndi Deum. It then tries to reconstruct the usage Rahner himself made of Aquinas's theology and Heidegger's philosophy, as presented in the latter's Sein und Zeit . In 1941, Rahner's major contribution consisted in reformulating Aquinas's theology on concupiscence in Heideggerian terminology. The Incarnation and the gift of integrity constituted two benchmarks that Rahner used to test his own understanding of concupiscence. Finally, Rahner's contribution is placed within the context of the Catholic-Lutheran Joint Declaration on the Doctrine of Justification and the definition of concupiscence as presented in the accompanying Official Common Statement
