shmendrick – “Follow carefully:
2. If one makes kiddush after plag is it shabbos for him? Yes.
3. Is there an issur melacha after making kiddush mi’beod yom? Yes.
4. Is saying “good shabbos” (once it is time to make kiddush) a kiddush? Yes.
5. Hence, saying “good shabbos” = kiddush, after plag, makes an issur melacha.”
Wow, I’m actually amazed at myself that I figured out your train of thought. I posted this above before your post now:
“shmendrick – After thinking it over -I’m begining to understand how you or your friend who fed you this got lost. It probably went like this – saying “Good Shabbos” is making Kiddush, once you made Kiddush you accepted Shabbos.”
And to that I answered:
“Nope -saying “Good Shabbos” is Not making Kiddush; just R’ A. Eiger had a Sofek if you were Yotzay Kiddush D’oraysa by saying “Good Shabbos”. It works only forwards, not backwards.”
But Shmendrick keep it up – I’m sure you’re fooling many people with your “Toras Emes”. It’s good to know that I live in the same town as such “Big Talmeidey Chachamim”!
