The Christian faith remains offensive to many. Although the (now increasingly obsolete) cultural phenomenon of postmodernism has enabled a revival of religion and spirituality, the Christian faith is still regarded as naïve in its reliance on the bible as divine revelation, narrow-minded in its exclusivist claims and, because of these claims, liable to incite conflict and violence. This lecture explores the validity of these prejudices by outlining the radically hermeneutic nature of the Christian faith. By drawing on the works of Martin Heidegger, Hans Georg Gadamer, Gianni Vattimo, Karl Barth, and Dietrich Bonhoeffer, Zimmermann argues that the Christian faith can relinquish neither its supposed naïve trust in a central text as revelation nor its universal claim to be the only true religion. Yet these claims have to be understood in the right way, and Christians themselves often missunderstand their true nature. The main thesis of this lecture is that Christianity is a deeply historical faith whose constitutive relation to God’s self-revelation in Jesus Christ has to be lived out interpretively. Only when the Christian faith understands itself as essentially hermeneutical can it uphold its universal claim to be the only true religion with the humility necessary to serve as a witness to the one who died to save the world.
