The Rishonim write at length about the special qualities of Shabbos. Rabbenu Avrohom the son of the Rambam, in Maspik Le'Ovdei Hashem (introduction), while presenting the first rule in avodas Hashem, writes that every mitzvas aseih and lo sa'aseh is identical for every Jew. No difference exists between Moshe Rabbenu, Yehoshua bin Nun, and the most ordinary person in Am Yisroel. Either a person fulfills or annuls the mitzvah. No differences in the general fulfillment or annulment of mitzvos exists.
