Wolf, Rav Hirsch, Ztz”l, addresses your questions. I did not process his discussion sufficiently to present it, but if you’d like, I can attempt to do so this Shabbos, IY”H.
(Maybe that “Jew of the Decade” award’s not a bad idea, after all. I nominate Wolf, on condition that the prize is a set of Rav Hirsch Chumashim.)
