Tough request, Yossi. What non-chabadnik is so familiar with all the sichos and the hidden code words of chabad that he can recognize where the Rebbe said he was moshiach, to thus be directly responsible for the thousands of apikorsim and ovdei avodah zarah everyone bumps into?
Fortunately, an answer was literally handed to me Simchas Torah when the Crown Heights folks walked in to join the dancing. It’s a pamphlet called “Yechi hamelech”, available for free by going into 770. The very beginning is a sicha from simchas torah 1985/5746. It’s about how everyone in that generation (of 26 years ago, October 1985/ simchas torah 5786) is born a shaliach (“messenger”, well-known to refer to those who follow the Rebbe’s teachings) of the nasi hador (the prince of the generation, a common phrase used to refer to the rebbe and all his miraculous doings). If the shaliach uses his power, he will turn the nasi hador into moshiach, and the Rambam says Moshiach is flesh-and-blood!
This is basically as strong as he can hint it without saying it in black-and-white.
Of course, the Rebbe was niftar on 3 tammuz 1994. So if the Rebbe was niftar, what happened to his promise that the nosi hador was moshiach and that everyone was born in the generation of moshiach?
the easy answer is that he was wrong. But since someone so great as to be tied into Hashem, that the issur of the Rambam of davening to a human as being a chelek of avoda zara no longer applied (apikorsus known as hiskashrus, check it out on identifying chabad), it can’t be he was wrong. So the Christain theology of today came about.
So yes, yossi, the Rebbe hinted at it enough to make everyone think he was moshiach, and is directly responsible for the ovdei avoda zara of today.
