Reply To: Must a Goy keep Shabbos?

My chavrusa suggested a tirutz – It depends why the goy is keeping shabbos – If he is doing it midin avoda zoro then it is okay; only if he is doing it midin shabbos it is a problem (He wanted to be medayek a Rambam that the only problem is the ????? ??, and that is not a problem if he is metzuveh). Doichek ketzas.
