I thought there would be no “chidushim” in this thread. I stand corrected
Chiddush 1
The Nefesh HaChaimin, in disagreement with his Rebbe, the GR”A, based his teachings on Chabbad Chassidus in”many” places. The evidence brought for this was NH 3-7. People who don’t know this are said to simply be unfamiliar with the NH. (Such people are probably also not familiar with the Kitvei Ramchal which dovetail nicely with the NH and preceded Chabad but never mind such pesky trivialities.)
Chiddush 2
It has always been normative Judaism to declare one’s Rebbe Moshiach It was the maskilim, in opposition to the very inyan of Moshiach, who opposed this and the Litvish oilem was of course mushpah from the maskilim. The evidence brought for this is the gemara in Sanhedrin and Rabbi Akiva declaring Bar Kochba Moshiach.
Got it
