Hostis humani generis
So? The gospels are just art, literary works of art.
Perhaps they are artistic, but to some extent the gospels are supposed to be based off of history as well as the life and ministry of Jesus. Whether or not one believes that they are, or whether they are or not is irrelevant to what I'm saying, though.
However, art is not the gospels, even though the gospels may be considered art. Nobody's faith is going to be destroyed if they find out a piece of art that is Jesus is identical to a Mithra statue, for example.
People base their life off of the teachings of the gospel that is attributed to Jesus. You will be hard-pressed to find someone who will base their life off a piece of art that is of Jesus.
Just sayin'.
