I've tried to explain to you problems with statements like "all mainstream jewish groups oppose jews for jesus".   If you can't understand this I'm not sure where else this can go.   Perhaps you might benefit from visiting the talk page off WP:NPOV and some other editor can explain why this is not permissibile at wiki.   Their are indeed many pov-pushing elements to this page.   Things like the gigantic "Christianity" template used to "warn" people abot this group.
As far as the blockquote, the combination of footnotes  and poor writing seemed to indicate it wasn't a quote.  It isn't appropriate to insert footnotes into someone else's quote  if he wants he'll create his own footnotes.  Cleaning up someone else's writing isn't POV.   The citation itself is a rewriting of the j4j belief statement.   And in this case, it is necessary: no self-respecting professional would use a phrase like "basically indistibuishable".
