No it's NOT. You are getting information from a cult's website. Which is lie after lie after lie mixed in with a tiny atom of truth to try and make it believable. What you take as truth is one of their many lies and deliberate misinterpretations. Going to Jew for JC's website to find out stuff about Judaism is like going to CNN to find out the truth about Obama.
There are hundreds of evangelical Christian missionary organizations that spend millions of dollars each year to convert Jews. Jews for JC is one of them. Despite any semblance of Jewish tradition utilized to mislead and entice, their theology is 100% Christian. In fact, many of their leaders aren't even Jewish. They are real true serpents, ready with lies to snare the undereducated Jew.
Please be a little more responsible about your sources before posting something as "da truth".
I go to the Old (and New) Testament to find out about Judaism. Jews for Jesus does also. That is our source. You are completely off base to call them terrible names. Please calm down and substantiate the charges that they are “serpents ready with lies”.
