Will a Noahide who observes a fully halachic Shabbat be punished by HaShem? I have personally been exposed to such an opinion which is based on b. Sanhedrin 58b; “ a heathen who keeps a day of rest deserves death”. I would appreciate your insight on this and how Sanhedrin 58b relates to Noahide Sabbath keeping.
Along the same lines I would also appreciate your insights on Maimonides, Misneh Torah, Laws of Kings and their Wars, Chapter 10, Halacha 9. How is the Rambam to be understood here in relation to gentiles keeping the Sabbath?
Your thoughts are much appreciated!
