“He said that the Rambams conditions are unapplicable to the Rebbe today as the Rambams terms were only written to determine someone who is alive. Not if moshiach comes from the dead.”
No offense, CS, but that’s a pretty cheap copout, considering the Rambam clearly writes Neherag, which implies that his criteria DOES apply to the dead. (If not, every Neherag could still theoretically be Moshiach Min Hameisim.”) Also, “Im lo Hatzliach Ad Koh” implies he’s dead, otherwise, how would we possibly know if he hasn’t succeeded? Maybe he will with more time?
Thus, the correct reading is “Im Lo Asa Kol Zeh (and he’s dead) OR EVEN IF he did do all those things (build the bais hamikdash etc) but he was neherag, he still isn’t Mashiach, because he was Neherag.
(This answers up the rambam with the Gemear of Anavim (the famous song): How could Moshiach stand on the bais hamikdash if in order to built itwe need a king, and if a king builds it, he’s Moshiach? The answer is that the king built it but he was killed. Hence, he wasn’t Moshaich.)
Either way, the Rebbe does not fit the Rambam and is thus not Moshaich.
