Moving away from proposals that would seek to build a systematic theology of religions, embracing them all under the same gaze - in an integrative way - the author pleads for a theology that reflects on the differences and makes them bear fruit by confronting religious traditions or positions in their full positivity. He outlines the possible benefits of this on three examples, Judaism, Buddhism, and contemporary quests for alternative spirituality. He also pleads for a work, also theological, on what is happening to the religious body. Finally, it opens up to a renewed way of reading religious traditions, both in their actual deployments and as bearers of fundamental problems. Apart from these detours, we can only remain with a view that unduly unifies a field of religions, conceals what is at work in them and what is to be thought about, and that proves to be prisoner of ethno-centric considerations.
