Can a Jew Lose His Jewishness

Can a Jew lose their Jewishness? This opening shiur in the Kedushas Yisrael series explores the halachic debate surrounding apostasy, assimilation, and Jewish identity. Drawing on the Gemara and Rishonim, it examines the distinction between a Jew’s core status and their ability to perform certain religious acts—and asks whether Jewishness is an unchangeable essence or a covenantal bond.
