Tyler Cowen from Marginal Revolution summarises some of René Girard's views in a very simple fashion. The first point, quoted below, reads a bit like the Nietzschean view but I may be mistaken: 

His understanding of Christianity as fundamentally and radically different from earlier religions, as it exalts the individual victim rather than the conqueror.  Here is one point from a summarizer: “Christianity is the revelation (the unveiling) of what the myths want to veil; it is the deconstruction of the mono-myth, not a reiteration of it—which is exactly why so many within academe want to domesticate and de-fang it.”
