Yes, I am aware of them.
Indeed, my allusion to the above was indirect.
I am afraid that I am not a classical textual scholar. I can read the stuff, but for me to pretend to comment on the differences and their meaning would be going beyond what I can really claim knowledge of.
What I can say is intellectually I don’t find it surprising. There was a period of what, 60 years of ferment with competing visions of the religion. In an era of oral transmission, it would not be at all surprising if subtle differences arose. Indeed it would be genuinely miraculous if they did not.
But they did. Clearly. Says nothing really - if one is a believer in God, then one more occasion where God let men transmit ‘the word’ within their own fallible context can hardly be surprising. If one is not, you just have to say, hey, yet again…
Now, the problem really occurs for the Salafistes. The true hard core fundies for whom the transmission issue is always glossed over. The rest of the Islamic world will get over it, I mean okay so we got some wrinkles in transmission. They’re not too bad, pretty small gap, maybe a few probably technical theological points of difference. Nothing to truly shake the religion. The Salafiste movements, however, this is very bad. No diff. really than the fundies in Xtianity and their bogus literalism (I add some handwaving apology for the characterization, but really the translation problems are so self-evident I have a hard time having any intellectual respect for the hyper-literalist crowd in re the bible).
In anycase, this will be something that will take 50 years to digest.
