Reply To: Eating on Erev Yom Kippur

I am surprised no one mentioned that the Rambam, in Hilchos Yom Hakipurim, completely omits any mention of the mitzvah to eat on erev Yom Kippur. However, in Hilchos Nedorim, the Rambam discusses the halochos of a neder not to eat on Yom Tov, Chanukah, and Erev Yom Kippur! There is a fascinating Aruch Hashulchan (in hilchos Yom Kippur) that addresses this stira in the Rambam, and concludes that the Rambam in fact holds that there is not even a mitzvah d’rabonon to eat erev Yom Kippur.
