Maimonides on Jesus

... there arose a new sect which combined the two methods, namely, conquest and controversy, into one, because it believed that this procedure would be more effective in wiping out every trace of the Jewish nation and religion. It, therefore, resolved to lay claim to prophecy and to found a new faith, contrary to our Divine religion, and to contend that it was equally God-given. Thereby it hoped to raise doubts and to create confusion, since one is opposed to the other and both supposedly emanate from a Divine source, which would lead to the destruction of both religions. For such is the remarkable plan contrived by a man who is envious and querulous. He will strive to kill his enemy and to save his own life, but when he finds it impossible to attain his objective, he will devise a scheme whereby they both will be slain.

The first one to have adopted this plan was Jesus the Nazarene, may his bones be ground to dust. He was a Jew because his mother was a Jewess although his father was a Gentile. For in accordance with the principles of our law, a child born of a Jewess and a Gentile, or of a Jewess and a slave, is legitimate. (Yebamot 45a).

Jesus is only figuratively termed an illegitimate child. He impelled people to believe that he was a prophet sent by God to clarify perplexities in the Torah, and that he was the Messiah that was predicted by each and every seer. He interpreted the Torah and its precepts in such a fashion as to lead to their total annulment, to the abolition of all its commandments and to the violation of its prohibitions. The sages, of blessed memory, having become aware of his plans before his reputation spread among our people, meted out fitting punishment to him.

Daniel had already alluded to him when he presaged the downfall of a wicked one and a heretic among the Jews who would endeavor to destroy the Law, claim prophecy for himself, make pretenses to miracles, and allege that he is the Messiah, as it is written, "Also the children of the impudent among thy people shall make bold to claim prophecy, but they shall fall." (Daniel 11:14).

Quite some time after, a religion appeared the origin of which is traced to him by the descendants of Esau (i.e. Rome), albeit it was not the intention of this person to establish a new faith. For he was innocuous to Israel as neither individual nor groups were unsettled in their beliefs because of him, since his inconsistencies were so transparent to every one. Finally he was overpowered and put a stop to by us when he fell into our hands, and his fate is well known.
