The very idea of a King Messiah...an idea also referred to by the names: the Final Redeemer and Savior...began in Judaism...not Christianity. It is an inherently Jewish topic regulated under the Laws of Judaism's Torah known better as the 5 Books of Moses.
For almost 2,000 years Judaism's Bible Sages have rejected Jesus as Judaism's King Messiah. With no offense intended to the good Christian viewers of this webpage we present Judaism's position on Jesus below. The intent is to share this classic Jewish commentary for the sole purpose of education and specifically not to slander nor offend Christians nor Christianity.
The Laws of King Messiah by Maimonides [one of Judaism's greatest Sages] were derived from all Sacred sources within Judaism. [See Messiah 101B] No subsequent Jewish Legalist has ever challenged them. They stand as Judaism's final Legal word on who and what King Messiah will be and must do according to Judaism.
Maimonides inserted a footnote into these Laws. The footnote was censored by the Church and only retrieved by an extant manuscript in Jerusalem of the original work. What the Church censored is provided here below.
""Jesus of Nazareth who aspired to be the Messiah and was executed by the court was also spoken of in Daniel's prophecies [Daniel 11:14], "The renegades 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 Messiah as the redeemer of Israel and their savior, who would gather their dispersed ones and strengthen their [observance of] the mitzvos[Commandments]. In contrast [the
founder of Christianity] caused the Jews to be slain by the sword, their remnants to be scattered and humiliated, the Torah to be altered, and the majority of the world to err and serve a god other than the L-rd."
"Nevertheless, the intent of the Creator of the world is not within the power of man to comprehend, for [to paraphrase Yeshayahu {Isaiah} 55:8] His ways are not our ways, nor are His thoughts our thoughts. [Ultimately,] all the deeds of Jesus of Nazareth and that Ishmaelite [i.e. Mohammed] who arose after him will only serve to pave the way for the coming of Messiah and for the improvement of the entire world, [motivating the nations] to serve G-d together, as it is written [Zephaniah 3:9], "I will make the peoples pure of speech so that they will all call upon the Name of G-d
and serve Him with one purpose."
"How will this come about? The entire world has already become filled with talk of [the supposed] Messiah, as well as of the Torah and the mitzvos. These matters have been spread among many spiritually insensitive nations, who discuss these matters as well as the mitzvos of the Torah. Some of them [i.e. the Christians] say:
"These commandments were true, but are not in force in the present age; they are not applicable for all time." Others [i.e. the Moslems] say: "Implied in the
commandments are hidden concepts that cannot be understood simply; the Messiah has already come and revealed them."
"When the true Messiah king will arise and prove successful, his [position becoming] exalted and uplifted, they will all return and realize that their ancestors
endowed them with a false heritage; their prophets and ancestors cause them to err."
