Reply To: Rav Chaim: A Nebach Apikorus is also an Apikorus

MediumThinker: I don’t remember where precisely, but look in the Moreh by where the Rambam defines Olam Habah. It’s somewhere towards the beginning. It’s pretty Mevuar. Also look in the Moreh (this might be a Peirush Hamishnayos somewhere, actually) where he discusses Halachos L’moshe Misinai.
