We do not believe G-d will assume a human form. Nowhere in Messianic prophecy is the Messiah G-d in human form or otherwise. Jews also do not believe anyone can assume responsibility for the sins of another. G-d also calls human sacrifice an abomination and condemns it in the strongest possible terms.
Technically speaking, God wouldn't have to assume a human form, and Messiah wouldn't have to redeem anything, if the first humans hadn't sinned.
Remember that if Adam had not sinned the whole concept of areas that are sanctified and areas that are not would not have existed. The whole earth would have been like גן עדן [the garden of Eden], and every place on earth would have enjoyed the status of sanctity. . . There similarly would not have been people specially selected to perform the service in the Sanctuary since the whole of mankind would have been a kingdom of priests and a holy nation. . . Man would not have been required to bring himself close to G'd by means of an animal sacrifice; he himself would have been the sacrifice . . ..
Rabbi Isaiah Horowitz, Shney Luchot Habrit, p. 681.
Why is man not the sacrifice? Because of the sin of Adam and Eve, phallic-sex, the conception of Cain. It's an abomination to sacrifice fallen man to God as though he could accept sinful flesh as recompense for sin:
Eve's sin was due to her being seduced by the serpent which had mated with her and introduced its pollutant into her body. . . Because of this, all the people born nowadays originate in what Rabbi Akavyah has called the טפה סרוחה, the smelly drop of semen. . . Ever since the sin, when Adam and Eve became aware that they were naked and became ashamed on that account, and the whole rite of circumcision became connected to עריה, nakedness and shame, observance of circumcision has become much more crucial.
Shney Luchot HaBerit, Torah Shebikhtav, Sefer Vayikra, Torah Ohr, Vayikra 7; Vayeshev, Miketz, Vayigash, Torah Ohr, 76.
It's not putting anything in the Shelah's mouth to say that circumcision becomes of the utmost importance after the serpent contaminates Eve. In this sense, the Shelah appears to be saying that circumcision undoes what was first done when the
smelly drop of semen first comes.
Through Milah [circumcision] it would be possible to return to the level of Adam and Eve before the sin. In other words, mankind would again have direct access to the spiritual dimension.
Rabbi Aryeh Kaplan, Inner Space, p. 166.
Since the "smelly drop of semen" comes through the organ Abraham bleeds, we don't appear to be reading too much into all this to imply circumcision symbolizes a return to a covenant and a time before semen comes to contaminated births.
Death, the literal dis-integration of the husk of the body, was the grim price exacted by meiotic sexuality. Complex development in protoctists and their animal and plant descendants led to the evolution of death as a kind of sexually transmitted disease.
Lynn Margulis, Symbiotic Planet, p. 90.
Pre-meiotic organisms didn't senescence and die. Death didn't indwell the physical body until the fleshly serpent (the flesh created in the image of the angel of death) opened the veil of Eve's temple and contaminated the seed of the woman with the poison (
smelly drop of semen) come, so to say, from its jowls.
. . . if man on earth had not failed and as a result become garbed in the pollutants emitted by the serpent [semen], there would not have been such a thing as shame, negative aspects to the act of procreation. . . semen would have been an emission originating in the brain, and the person born as a result of such an emission would have come into the world with the same stature as Adam.
Shney Luchot HaBerit, Torah Shebikhtav, Vaera, Torah Ohr, 39.
Through Milah [circumcision] it would be possible to return to the level of Adam and Eve before the sin. In other words, mankind would again have direct access to the spiritual dimension.
Rabbi Aryeh Kaplan, Inner Space, p. 166.
Everything depends on circumcision returning mankind to the status of Adam and Eve prior to the first act of meiotic sex where, i.e., meiotic sex, the sexually transmitted disease Judaism refers to as the "evil inclination" contaminates everyone born when the fleshly serpent enters the crevice of the woman to conceive a nest of vipers. Semen, and the serpent it rides in on, is, according to the holy Shelah (Rabbi Isaiah Horowitz) the source of the sin and death that didn't exist until Adam's semen rode Adam's serpent to Eve's temple where and when it entered the crevice in her earth and turned the holy place of her temple (the bedchamber of the temple) into a den of vipers fit to raise a lot of Cain throughout the pages of human history.
Cut and bleed the serpent (
brit milah) . . . cut all the way to the bone of truth (eliminate, emasculate) . . . and if, despite that emasculating blood דם ברית, the seed of the woman still comes out of that crevice, with the veil of the temple still intact at birth, so that he opens the womb, is a "womb-opener" פטר רחם (Exodus 13:2), then he's fit to be sacrificed to God in order to redeem everyone whose patrilineage, whose lineage, stops, where the serpent entering Eve starts. This virgin-born messianic personage fit to be a sacrifice is clearly stillborn in the pages of the Tanakh, but he's still born in the pages of the Gospels and Apostolic writings.
