well, PM, I am not sure how I scored political points in my reply. Check my most recent entry re: civility. I suggest that your original entry in reference to Rabbi klass totally lacked in that.Your last entry concerning Rabbi Klass falls in the same category. I am pretty sure that many Poskim have written similar , possibly faulty teshuvos without incurring your or other people’s wrath. As I never saw the teshuvah you are writing about, I cannot claim to know what Rabbi Klass wrote. Hence, I can only restrict myself to what I know. However, just a few remarks about this last entry (before I turn to the earlier one).
I have to respect your erudition and if that is the case, you would know that R”Moshe zz’l was a meikel in most cases EXCEPT in hilchos shabbos. For whatever reason, in that realm he was not meikel. Do you use liquid soap on shabbos? Well, r’Moshe says it is ossur. There are other examples (eiruv is one of them)but I will not dwell on them.
i daresay that there is not “pessul’ in basing a hetter on one possek, it is done all the time,especially ‘beshaas hadchak”. I don’t know the circumstances of Rabbi Klass’ writing so i cannot say this was the case but you cannot just dismiss a hetter because only one possek says it is so. The two Poskim you mentioned were giants in their time (the Aruch HASHULCHAN AND R’zzi pessach frank)and one can certainly rely upon them if needed. After all, you are relying upon the Chazon Ish for a chumro. isn’t he one solitary possek?
I can certainly add the Maharashdam to this list of mattirim and he was the greatest Possek in the early twentieh century in galicia and romania. not good enough for the Lithuanians maybe but good enough for me. I’ll be glad to refer you to the relevant people on that.
Lastly- on this matter- until today no one can claim to tell me or anyone that you know today how electricity works,especially in relation to melochos. Where is it stored? Does it disappear? how does the connection of a circuit suddenly make it come alight? and if thomas edison would not have invented the electric bulb, how would we even know where it went? i am not asking this just to be ‘mekanter’ but if you speak to scientists they will all tell you that what we think about electricty in connection with ‘melochos’ makes no sense. I am not here to pasken according to scientists but then again, you cannot just dismiss the Poskim who though using electricity did not contravene any halochos.
As far as your earlier entry on yom tov, at least you allow the fact that one can lower a flame to let the food simmer- well, can you lower the flame to the point that only the pilot is on? And if you say no, why not? there is still heat emanating from that source and you can actually heat up food on a pilot light ( I have done it)
Lastly- what makes the melocho of “mechabeh’ different than ANY other melocho so that you suggest that you cannot use mitoch??? jelamdenu rabbeinu, with some cogent sources.
