I know I said this somewhere, but I can’t find it, & can’t remember the context in which I said it. But I’ve got a feeling it wasn’t quite as you seem to be interpreting it - as I don’t actually believe there is any evidence of tampering with the biblical texts - in the way that muslims assert or my friend believes.

Actually, when I read the same stories in the bible and the Koran, the story of Joseph in the OT for instance, there is no question to me which of the two versions tampers with the truth. I leave it to you to guess, on the basis of what I have said so far, which version you think I trust.
