I have to admit that I am still not getting it.
What I seem to understand is that there is a scholastic argument about who takes what scriptures into account on what basis. Fair enough, it appears to me, to take different stances on that.
Then it moves into labelling these differing stances. Ok, to quote Goethe' Faust "Name ist Schall und Rauch" (= what's in a name?). And now we are moving into the territory of "if you are not/do not, you don't belong"?
Why does it matter, really, what label we carry and where differences lie,considering we are all different anyway?
Labels can be useful, if they serve a purpose. What purpose is served here?
