Epikoros

Epikoros (or apikoros or apikores; , pl. epikorsim; ) is a Jewish term figuratively meaning "a heretic", cited in the Mishnah, that refers to an individual who does not have a share in the World to Come:

The rabbinic literature uses the term epikoros without a specific reference to the Greek philosopher Epicurus, but some understand that the term is derived from his name. Epicurus was a materialist philosopher whose views contradicted Hebrew Bible, the strictly monotheistic conception of God in Judaism, and the Jewish belief in the World to Come (see ).
