Living together in religious diversity seems to be a feature of European identity. But religious debates and conflicts shake the success of this coexistence. In the face of nationalist ideology, often based on the Christian character of Europe, the question arises as to whether religious diversity in Europe is actually understood as a natural part of European identity. The Roman Catholic and Protestant churches have repeatedly commented on this increasing religious diversity and the shaping of coexistence. In doing so, both churches balance between regretting, greeting and accepting this plurality in the struggle for their own confessional standpoint and openness to other religions.
