The uniqueness and the scandal of the Christian religion rests on the mediation of revelation through historical events. Christianity is not just a code for living or a philosophy of religion. It is rooted in real events of history. To some people this is scandalous because it means the truth of Christianity is inexplicably bound up with the truth of certain historical facts. And if those facts should be disproved, Christianity would be false. This, however, is what makes Christianity unique because, unlike other world religions, modern man has a means of actually verifying Christianity’s truth by historical evidence.
