I know (with my Ruach HaKodesh) someone who always uses the Holocaust to “prove” that Chachamim never had, nor will have Ruach HaKodesh, Taas Torah and etc.
And he’s wrong every single time (he doesn’t have Ruach HaKodesh!)
They use the mantra (they were indoctrinated, force-fed, since youth) “look at this great Rabbi, why didn’t he save his Kehilla?” And they attempt, with that and other ploys, over and over again, to try to lessen our adherence to Chachmei, Gedolei Yisroel. They try time and again to wean us from our עיני העדה…
I believe I once answered those claims (many years and many screen names ago!) I’ll try now – from memory:
1) A Tzadikkk’s Ruach HaKodesh comes from “Kodesh” – HaShem (Oh really?!) So although HaShem generally stands by and guides his closest, HaShem, in His infinite intelligence, for reasons we as mortals cannot fathom, decides at times to withhold his assistance.
2) That era was an era unparallel in Jewish history, actually in all of world history. A time of Heavenly “Anger” (ריתחא). A great, painful הסתר פנים (again – for reasons known only to HaShem) where HaShem so to speak turned His face away from His nation. And we’ve heard from our Greats – they felt their divine assistance vanished. ואבדה חכמת חכמיו ובינת נבניו תסתתר, a great a fearful prophesy, was said regarding this terrible era. So NATURALLY some Gedolim lost their powers. Others were extended unquestionable Ruach HaKodesh EVEN in that horrible period.
3) Certain Gedolim understood all too well, and decided it was better to perish in this world and not in the next. It was Nebach done all through our long and bitter Galus. We mention a few on Tisha Ba’av, where a father would take his children…
