"It is clear to me that the writings of the christians are a lie, and that your fables are not well-enough constructed to conceal this monstrous fiction: I have even heard that some of your interpreters, as if they had just come out of a tavern, are onto the inconsistencies and, pen in hand, alter the originals writings, three, four and several more times over in order to be able to deny the contradictions in the face of criticism." (Celsus 178 CE) [2]"

Nibley and his ilk are plying an ancient profession.

I knew that the truth about the lie of xstianity had been obscured by time, and deliberate rationalizations, but it never occurred to me that writers would have called out the xstians during their early days.
