Vattimo’s ‘weak thought’ leads him from philosophy straight into the theological field. It claims to have no other option, as it inevitably lays bare its own Christian provenance. Vattimo’s exploration of this provenance shows ‘weak faith’ to be the only possible way to live an authentic late-modern Christianity. I shall contend that, despite the intriguing perspectives and provoking challenges of Vattimo’s writings, the nihilist erasure of the difference between thought and faith, what I call
epistemo-theology, is not the best late-modern philosophical option for Christianity. Rather, I consider an option that Vattimo closes off together with the metaphysical one, more promising, philosophically as well as theologically, and that is differential thought, more precisely the path opened up by Derrida. This way, the relation between philosophy and theology turns from
(pre-modern) ancilla via (modern) dominatrix into (post-modern) amica.
