Two powerful Jewish organizations are lashing out against the decision to hire Mel Gibson to produce a movie about biblical Jewish hero Judah Maccabee ... TMZ has learned.

The Anti-Defamation League has released a statement -- demanding Warner Bros. pull Gibson off the flick immediately ... saying, "As a hero of the Jewish people and a universal hero in the struggle for religious liberty, Judah Maccabee deserves better."

The statement adds, "It would be a travesty to have the story of the Maccabees told by one who has no respect and sensitivity for other people’s religious views."

TMZ also spoke with Rabbi Marvin Hier -- founder and Dean of the Simon Wiesenthal Center -- who tells us putting Mel Gibson work on a movie about a Jewish hero is "like having a white supremacist portray Martin Luther King Jr."
