shmendrick -“Heath, if you have a Piskei Tshuvos (by my chaver tov Rav B.Z. Rabbinowitz), look up s. 271, s”k 6 at foot note 66.
There he brings the shitos both for and against the underlying rule which is the MG”A who holds that we are yoteh kiddush midoraysa in tefilah, since “saying” is all what is requird midoraysa. This is consistent with Reb Akiva Eiger and the Tshuvos HaRarshba (Vol 4, s. 295). The olom follows this MG”A (which is why women who normally may not daven ma’ariv during the week, daven ma’ariv Friday night – to equalize their chiyuv of kiddush with their husband).
The M.B. has issues with the MG”A and RA”E as I noted but that is besides the point.
Also and related, see Be’er Hetev s. 307 s”k 2 and Mishna Brura s”k 5 in name of Shal”ah the ma’alah of saying “shabbata tova” (gut shabbos) – v’ten l’chochom v’yechkam od.”
You seem to be a learned person, (unless s/o is just feeding you this stuff), so how come you didn’t understand my simple post???
“In any event, since we are dealing with a situation of issur dioraysa of chilul shabbos, this is very serious, and one must be machmir rather than laugh off the issue.
This isn’t merely a debate over ego matters or to shtoch someone or be holier than thou.
Be mekabel for your own sake, and if not, at the very least do not let your ego be machshil es harabim to accept your folly.”
Let me try again. I honestly don’t know why this RY or whomever it was, started this Chumra, but if it comes from the R’ A. Eiger it makes No Sense! R’ A. Eiger was wondering whether saying “Good Shabbos” on Shabbos is good enough for s/o to be Yotzay Kiddush with. And I already posted that the Biur Halacha finds this Shaila to be a Pelah so obviously he doesn’t agree with it – Not like you said above.
Now let’s talk about the R’ A. Eiger. Let’s say he holds for sure (in reality he had a Sofek) that you’re Yotzay Kiddush. This just means that saying “Good Shabbos” you have mentioned Shabbos acc. to the Mitzva of Zechira. This has nothing to with Kabbalah. You can’t possibly learn from this that saying Good Shabbos means you accepted Shabbos. So you have no proof that if s/o says Good Shabbos this means he is saying to Mekabel the Shabbos.
So stop with it’s Ossur to say Good Shabbos on Fri.
At the most it can be a Chumra – perhaps it lacks in Kovod Shabbos saying Good Shabbos when it’s Fri. But this is doubtful because you are wishing the other person now for later on.
