Q1, So if Yaakov is alive, even though we cant understand in what way, how does it help the discussion here about Chabad? Q2, Where does Chabad get the idea LR can be alive? Q3, What source do they have that its even possible in our days? Q4, What source is there for LR specifically?
You’re right, the discussion has nothing to do with Chabad.
It started when Philosopher exposed her ignorance to all by opening this discussion with the following post:
“It is Lubavitche like you who twist everything out of context. For example when Rashi says that Yaacov avinu did not die there are numerous mefarshim that explain what it means. There is no mefoiresh saying that he is here with us physically. And yet i heard a Chabad rabbi claim that Rashi said that Yaacov is with us physically; that is a lie.”
This is reminiscent of the time when Qwerty thought that chazzir becoming kosher when Moshiach comes was some kind of Chabad “kefira” ðŸ¤.
