[Avodah] The Arukh haShulchan, and R SZ Auerbach on Electricity on Shabbos

[Micha Berger]

RSZA (Minchas Shelomo 1:9-12, centrally #11) holds that use of electricity
on Shabbos (to do things that would otherwise be mutar) is only assur
because of the universal acceptance of such a prohibition by the global
observant community and our rabbis.

This idea that a universal acceptance can create a deRabbanan even without
Sanhedrin shows up in AhS YD 90:14. (In AhS Yomi for last Monday.
<http://aishdas.org/ahs-yomi>.) The siman discusses the kashrus of udders,
and how to get the milk out. Milk that was in the cow at the time of shechitah
is milchigs, but only derabbanan.

The case is a pashtida (some kind of filled bake good) that contains
an udder that was kashered to roasting standards. Should it be treated
like something made in a pan or a pot, even though the pashtida was made
directly over the fire? (And the meat is within the pashtida.)

The Taz (s"q 8) says in the name of the Rashal that the common acceptance
not to eat such a pashtida (tart?) has all the power of a derabbanan
and shouldn't be eaten even bedi'eved / hefsed merubbah.

The AhS rejects this line of reasoning, saying that okay, the geonim
strengthened the general topic of udders and their milk, so it's enough
to be machmir lekhatchilah. But saying that bedi'eved too, because the
pashtida extension is effectively an issur derabbanan -- that's going
too far.


Tir'u baTov!
