Is Christianity unique or not?

[Angrboda]

Was Christianity in some sense original and unlike other bullshit circulating at the time, regardless of specifics? No. It didn't take a creative genius to think up most of the shit in Christianity, at least in the broad outlines.

This reminds me of the challenge in the Quran to produce a surah comparable to the divinely inspired surahs inside it. The supposed point being that if you can't produce a surah that would pass for an original, it proves that humans are incapable of composing the Quran and thus it must have had a divine source. I suspect the point is a similar point of pride for Christians, that the uniqueness of Christianity says something significant about its source as well as its value in human history. I don't find either to be likely a correct inference from the facts. Uniqueness isn't really a signature of anything unless in that uniqueness it is shown that the thing in question also posssesses unmistakable goods independent of its claimed uniqueness. Only then does it become remarkable, perhaps. Regardless, I don't think Christianity itself passes either test.
