In this episode we explore Rav Moshe Feinstein's opposition to Bas (and Bar) Mitzvah ceremonies - found in Igros Moshe (O.C. 1:104, cf. 2:97 and 4:36) - as well as a brief nod to his relatively permissive stance on using a single dishwasher for meat and dairy (separately). At the end. Rav Elchanan Poupko articulates what made Rav Moshe Feinstein uniquely deserving of the status as a posek hador, a preeminent halachic authority of his generation.
