Qwerty,
I refrained from answering your question because I’m not interested in going down the rabbit hole of discussing Christian theology, nor do I wish to engage in the Who is Moshiach debate (something I haven’t shared my views on, for reasons explained in a previous post).
I would rather discuss a Gemara, a Rambam, a Rashi, a Maharsha, a Gra, a Likkutei Sichos, etc.
However, since you pressured me so much, I will give you a brief and honest response:
Candace Owens…asked America’s Rabbi why Lubavitchers reject Christianity because of its belief in a second coming
If Jews reject Christianity because of the second coming, why did beis din kill Yoshke In the first place?
That is my answer (it’s a rhetorical question).
P.S. Rambam Hilchos Melachim ch. 11:
אַף יֵשׁוּעַ הַנּוֹצְרִי שֶׁדִּימָה שֶׁיִּהְיֶה מָשִׁיחַ, וְנֶהֱרָג בְּבֵית דִּין, כְּבָר נִתְנַבֵּא בּוֹ דָּנִיֵּאל, שֶׁנֶּאֱמַר “וּבְנֵי פָּרִיצֵי עַמְּךָ יִנַּשְּׂאוּ לְהַעֲמִיד חָזוֹן וְנִכְשָׁלוּ” (דניאל יא, יד). וְכִי יֵשׁ מִכְשׁוֹל גָּדוֹל מִזֶּה, שֶׁכָּל הַנְּבִיאִים דִּבְּרוּ שֶׁהַמָּשִׁיחַ גּוֹאֵל יִשְׂרָאֵל וּמוֹשִׁיעָם, וּמְקַבֵּץ נִדְחֵיהֶם וּמְחַזֵּק מִצְוָתָן, וְזֶה גָּרַם לְאַבֵּד יִשְׂרָאֵל בַּחֶרֶב, וּלְפַזֵּר שְׁאֵרִיתָם וּלְהַשְׁפִּילָם, וּלְהַחֲלִיף הַתּוֹרָה, וּלְהַטְעוֹת רוֹב הָעוֹלָם לַעֲבֹד אֱלוֹהַּ מִבַּלְעֲדֵי ה’.
“Jesus of Nazareth who aspired to be the Mashiach and was executed by the court was also alluded to in Daniel’s prophecies, as ibid. 11:14 states: “The vulgar among your people shall exalt themselves in an attempt to fulfill the vision, but they shall stumble.”
Can there be a greater stumbling block than Christianity? All the prophets spoke of Mashiach as the redeemer of Israel and their savior who would gather their dispersed and strengthen their observance of the mitzvot. In contrast, Christianity caused the Jews to be slain by the sword, their remnants to be scattered and humbled, the Torah to be altered, and the majority of the world to err and serve a god other than the L-rd.”
P.P.S. Responding that “according to some opinions beis din didn’t kill Yoshke” doesn’t refute my point.
