Quote from Username: “Rebbes don’t have any independent power, just as the sun doesn’t have any independent power. All the power that they have is what Hashem gives them.”
Obviously.
My point was that Hashem didn’t give over his every power to the Rebbe. In my mind that’s still kefira. I have met lubavitchers who believe that the Hashem gave over all his powers to the Rebbe, and some say, even placed himself in the Rebbe’s guf, and THEY TELL ME it’s kefira, because I believe that Hashem has limits! It’s not that Hashem has limits, it’s that there are certain things Hashem doesn’t do, such as give over all his powers to a ben-adam.
This is why “The Rebbe runs the world” is kefira, plain and simple.
