Alex Woinski, an eighth-grader at West Brook Middle School in Paramus, was sent home from school on Friday.
Woinski, who has shoulder-length brown hair, wore a white robe, a red sash, sandals, a fake beard and a crown of thorns. His mother told The Record of Bergen County that Alex was told he could keep the costume on if he removed the beard and crown of thorns.
Superintendent James Montesano said the district doesn't want students wearing costumes that could be distracting.
Woinski's mother is Catholic, while his father is Jewish. She says her son recently celebrated his Bar Mitzvah and is studying Bible scripture.
