Prophecy returns (Shabbat Parshas Shoftim, 5751)

"It must be publicized to all members of the generation that we have merited that G-d has chosen a person endowed with free choice, who is incomparably higher than the members of this generation, as the judge, counselor and prophet of the generation, to provide instruction and advice pertaining to the service of all Jews.... [His council extends] to the most fundamental prophecy - "Redemption is imminent" and immediately, literally, 'Behold he (Moshiach) comes."'

Moshiach is revealed, literally (Shabbat Parsha Vayeira, 5752)

"At the present time, all obstacles and hindrances have been nullified. As such, Moshiach (not only exists, but in fact), is also already revealed. All we have to do now is welcome Moshiach Tzidkeinu in actual reality."

Not only in potential, but a definite Moshiach (Parshas Mishpatim, 5752)

"...The ruling of the rabbanim and halachic authorities that the time of the Redemption has arrived - i.e. "A king will arise from the House of David... it is presumed that he is Moshiach," [- the Rebbe added to the halachic ruling :-] "until the state of "definitely Moshiach."
