Although I haven't personally seen the letter (hopefully I will tomorrow night), it seems clear that this would have a serious effect on the core teachings. How do you go from listen to us unquestioningly, even when we're wrong we're right and if you THINK about doubting us you're gonna die to "Well, all of what we say is open to interpretation and these are just suggestions?"
How do you reconcile things like the blood issue, neutrality, holidays, even dress and grooming to this stance?
