Rabbis have to stop dismissing everything that comes from outside the Beis Medrash.
Like other chassidic dynasties, Bobov was not immune to one day experiencing a schism. When Rabbi Naftali Zvi Halberstam, the fourth Bobover Rebbe, died in 2005, a dispute arose over who would succeed him. Some chassidim sought to appoint his younger half-brother, Rabbi Ben Zion Aryeh Leibish Halberstam, as the next rebbe; and others sought out the fourth rebbe’s sons-in-law: Rabbi Mordechai Dovid Unger as the rebbe, and Rabbi Yehoshua Rubin as the Bobov rav (serving as head of the bet din and as the posek).
