Before the passing of the Rebbe, I included myself among those who believe that the Rebbe was worthy of being Moshiach. And I strongly believe that had we, particularly the Orthodox community, been united, we would have merited to see the complete Redemption. Insofar as the belief . . . that the Rebbe can still be Moshiach, in light of the Gemara in Sanhedrin, the Zohar, Abarbanel, Kisvei Arizal, S’dei Chemed, and other sources, it cannot be dismissed.
