It depends on the nature of the "non-believer". A non-Jewish person is called a Gentile or Goy (גוֹי), but gentiles are NEVER referred to as "non-believers". Unlike other religions, Jews do not assess the beliefs of non-Jews, (or regard them as believing less than what Jews believe). If the non-believer is a Jewish heretic, the person is usually called a Kofer or Apikorus, but these terms are only used among Orthodox Jews. Non-Orthodox Jews shy away from the concept of heresy, and would generally use the terms of their native language, such as "cultural Jew," "Humanistic Jew," "Secular Jew," "atheist," or "agnostic". The Hebrew equivalents of these phrases are: humanistic Jew: "yehudi hoomanisti" (יהודי הומניסטי) cultural Jew: "yehudi tarbutí" (יהודי תרבותי) secular Jew: "chiloní" (חילוני) atheist: "ah-teh-eest" (אתאיסט) agnostic: "kofér" (כופר)
