Rabbinic Criteria:

Maimonides states that Mashiach will rebuild the Holy Temple, which has not happened, disqualifying the Rebbe’s identification as Mashiach according to halachic standards.

Physical Leadership:

The Rebbe did not physically lead the Jewish people to Israel or gather the exiles, a key function of Mashiach that remains unfulfilled.

Posthumous Declaration:

The concept of a Mashiach after death contradicts traditional understanding, as Mashiach is expected to accomplish specific tasks in his lifetime.

Scriptural Rebuttals:

Traditional sources focus on actions, not birthdates, as proof of Mashiach’s identity, emphasizing the need for tangible accomplishments.

Fulfillment of Prophecy:

The prophecy involves universal peace and the Temple, which are not yet realized, challenging the Rebbe’s claim as Mashiach.

Rabbinic Consensus:

Maimonides explicitly requires the physical building of the Third Temple, which has not occurred, reinforcing the argument against the Rebbe.

Living King:

The fundamental principle is that Mashiach is a living king who completes his mission in his lifetime, a view held by the majority of rabbinic authorities.
