Trump adviser Stephen Miller’s childhood rabbi eviscerated him and his role in President Trump’s anti-immigrant policies, like the administration’s family separation policy, during a Rosh Hashanah sermon Monday, the Guardian reported.

Miller, Rabbi Neil Comess-Daniels of Beth Shir Shalom said, had spread “negativity, violence, malice and brutality.”

“Honestly, Mr. Miller, you’ve set back the Jewish contribution to making the world spiritually whole through your arbitrary division of these desperate people,” Comess-Daniels said, per the Guardian. “The actions that you now encourage President Trump to take make it obvious to me that you didn’t get my, or our, Jewish message.”

The rabbi assured his congregation “that what I taught [Miller] is a Judaism that cherishes, wisdom, values … wide horizons and an even wider embrace … [Separating families] is completely antithetical to everything I know about Judaism, Jewish law and Jewish values.”

“In a free society, some are guilty, all are responsible,” he added. “Because we want this society to remain free, we will continue to act.”
