I was responding to Rav's remark that said, "Yeah, everyone's just reaching out and touching a different part of the 'spiritual elephant', right? Wrong. You can't reconcile things this way as long as there are teachings that explicitly state that you can't reconcile things this way, which there are."
If all of those "teachings" are stated in private languages unique to a particular religion, incommensurable with one another and incomprehensible to those outside the religion in question, then Rav's situation would seem to be impossible. The 'spiritual elephant' argument, which I kind of like and was trying to defend, would still be consistent with the various religions all loudly denying the validity of their rivals.
