I wasn't commenting on the "Jews for Jesus" cult, I was merely saying that a person can be a Jew and also believe in Jesus, and that it is not a conflict of interest if they do.

One can be a Jew and believe in just about anything, because to be a "Jew" is a cultural designation or an indication of whom one was born to, it is not necessarily a religious designation...or an indication of one's adhering to any particular belief system.
