Around Channukah 2007, I asked my Rav how we can make the bracha of "asher kidishanu... l'hadlik ner channukah" when, in fact, God never gave us such a commandment.*
His answer (which I belive is the classic one) is that we're commanded to listen to the words of the sages, so, in effect, it's as if God Himself did command us.
Okay, that's fine.
I finally thought of the follow up question (yeah, I know it's a year and a half -- I never claimed to be the sharpest knife in the drawer):
So, why then don't we recite the bracha of "asher kidishanu... lishmoa divrei chachamim" (to listen to the words of the sages) or some variant thereof. If that's the actual God-given commandment that we're following, then why not that bracha?
Anyone have any ideas?
*Of course, the same goes for the bracha before Hallel and the other mitzvos d'rabbanan.
