Many of their "rabbis" do not believe in G-d.
Their members are largely cultural jews..
A famous reform/liberal/conservative "Rabbi", in britain, Baroness Neuberger, in an interview, said that in her community, if anybody were to speak about a personal G-d that they can pray to, then everybody else would look at them like they were mad.
Another one, "Rabbi" Dr Jonathan Romain, has written of his wish to literally rewrite the bible, removing the violent parts. I would call them ministers, not rabbis.. And their place is not a synagogue.. and certainly not a "temple".
They only call it temple, because they don't believe the temple will be rebuilt. So they call their "synagogues" "temples". So people forget about it.
WOW, is all I can see.
So, cultural Jews, eh. Or as some people call them "Chanukah Jews", not "acting" Jewish throughout the year except when it comes to get their Chanukah presents.
There are rosh hashana yom kippur jews.. They probably like purim and chanukah too.
I wouldn't call them chanukah jews though.. And I am sure that neither would Kahane. Kahane wrote an article, sarcastically titled "down with chanukah".. on how chanukah is so popular, yet the lesson of chanukah is so foreign to jews today. Kahane was a maccabee.
What I said is verifiable and well known.
Not to be confused with people linking the reform/conservative movement to the shabbetai tzvi who believed in being righteous through sin. There is some basis to that too.. I have read rabbi antelman's "to eliminate the opiate" vol 1 and 2, and I have checked his references, largely "the messianic idea in judaism" by gershom scholem. But really you don't need to speculate or go into that..
Reform, based on what the reform leaders have said themselves. Is just not worth the time of day.
This from David Friedlander - wikipedia
" Friedländer's open letter (Sendschreiben) "in the name of some Jewish heads of families," stated that Jews would be ready to undergo "dry baptism": join the Lutheran Church on the basis of shared moral values if they were not required to believe in the divinity of Jesus and might evade certain Christian ceremonies.
"
And it mentions moses mendellsohn.. Rabbi antelman published his ordination certificate which has sabbeatean codewords.. very odd.
And sabbeteans believed in being righteous through sin. some still exist today (donmeh west website)
But you can see enough just looking at todays reform/liberal/conservative ministers.. As I said, as examples. neuberger , jonathan romain, e.t.c.
They are not sinister sabbateans.. Just idiots, cultural jews with some weak attachment to being jewish.
