In Judaism, the Seven Laws of Noah (Hebrew: , Sheva Mitzvot B'nei Noach), otherwise referred to as the Noahide Laws or the Noachian Laws (from the Hebrew pronunciation of "Noah"), are a set of imperatives which, according to the Talmud, were given by God as a binding set of universal moral laws for the "sons of Noah" - that is, all of humanity.
According to the Jewish law, non-Jews (gentiles) are not obligated to convert to Judaism, but they are required to observe the Seven Laws of Noah to be assured of a place in the World to Come (Olam Ha-Ba), the final reward of the righteous. The non-Jews that choose to follow the Seven Laws of Noah are regarded as "Righteous Gentiles" (Hebrew: , Chassiddei Umot ha-Olam: "Pious People of the World").
The Seven Laws of Noah include prohibitions against worshipping idols, cursing God, murder, adultery and sexual immorality, theft, eating flesh torn from a living animal, as well as the obligation to establish courts of justice.
According to the Talmud, the seven laws were given first to Adam and subsequently to Noah. However, the Tannaitic and Amoraitic rabbinic sages (1st-6th centuries CE) disagreed on the exact number of Noahide laws that were originally given to Adam. Six of the seven laws were exegetically derived from passages in the Book of Genesis, with the seventh being the establishment of courts of justice.
Seven commandments were commanded of the sons of Noah:
According to the Genesis flood narrative, a deluge covered the whole world, killing every surface-dwelling creature except Noah, his wife, his sons, and their wives, and the animals taken aboard the Ark. According to the biblical narrative, all modern humans are descendants of Noah, thus the name Noahide Laws is referred to the laws that apply to all of humanity. After the Flood, God sealed a covenant with Noah with the following admonitions (Genesis 9:4-6):
And in the twenty-eighth jubilee Noah began to enjoin upon his sons' sons the ordinances and commandments, and all the judgments that he knew, and he exhorted his sons to observe righteousness, and to cover the shame of their flesh, and to bless their Creator, and honour father and mother, and love their neighbour, and guard their souls from fornication and uncleanness and all iniquity. For owing to these three things came the flood upon the earth ... For whoso sheddeth man's blood, and whoso eateth the blood of any flesh, shall all be destroyed from the earth.
The Encyclopedia Talmudit, edited by rabbi Shlomo Yosef Zevin, states that after the giving of the Torah, the Jewish people were no longer included in the category of the sons of Noah; however, Maimonides (Mishneh Torah, Hilkhot M'lakhim 9:1) indicates that the seven commandments are also part of the Torah, and the Babylonian Talmud (Sanhedrin 59a, see also Tosafot ad. loc.) states that Jews are obligated in all things that gentiles are obligated in, albeit with some differences in the details. According to the Encyclopedia Talmudit, most medieval Jewish authorities considered that all the seven commandments were given to Adam, although Maimonides (Mishneh Torah, Hilkhot M'lakhim 9:1) considered the dietary law to have been given to Noah.
Menachem Mendel Schneerson, the Lubavitcher Rebbe, published and spoke about the Seven Laws of Noah many times. According to Schneerson's view, based on a detailed reading of Maimonides' Hilkhot M'lakhim, the Talmud, and the Hebrew Bible, the seven laws originally given to Noah were given yet again, through Moses at Sinai, and it's exclusively through the giving of the Torah that the seven laws derive their current force. What has changed with the giving of the Torah is that now, it is the duty of the Jewish people to bring the rest of the world to fulfill the Seven Laws of Noah.
According to Michael S. Kogan, professor of Philosophy and Religious studies at Montclair State University, the Seven Laws of Noah aren't explicitly mentioned in the Torah but were exegetically extrapolated from the Book of Genesis by 2nd-century rabbis, which wrote them down in the Tosefta.
According to Adam J. Silverstein, professor of Middle Eastern studies and Islamic studies at the Hebrew University of Jerusalem, Jewish theologians started to rethink the relevance and applicability of the Seven Laws of Noah during the Middle Ages, primarily due to the precarious living conditions of the Jewish people under the Medieval Christian kingdoms and the Islamic world (see Jewish-Christian relations and Jewish-Islamic relations), since both Christians and Muslims recognize the patriarch Abraham as the unifying figure of the Abrahamic tradition, alongside the monotheistic conception of God. Silverstein states:
[...] Perhaps under the influence of the historical circumstances just mentioned, Jewish theology came to include concepts and frameworks that would allow certain types of non-Jews to be recognized as righteous or even deserving of a portion in the Hereafter. The central concept in this context is the idea of "Noachide Law", this being a set of seven largely moral laws (prohibiting theft, murder, adultery, and the like) that are intended for all but the Jews. There are thus two "Torahs": one for the Jews, the other for the other "Children of Noah" and those who follow the rules stipulated for them (be they Jews following the Torah or Noachides following the code devised for them) will be rewarded accordingly. Crucially, in addition to the moral laws prescribed for non-Jews are prohibitions against blasphemy and idolatry. Thus, although in theory the Noachide Law should be universal, it only really applied to non-idolatrous theists, and in actual fact Jews almost always had Christians and/or Muslims in mind when considering the concept.
David Novak, professor of Jewish theology and ethics at the University of Toronto, presents a range of theories regarding the sources from which the Seven Laws of Noah originated, including the Hebrew Bible itself, Hittite laws, the Maccabean period, and the Roman period. Regarding the modern Noahide movement, he denounced it by stating that "If Jews are telling Gentiles what to do, it's a form of imperialism".
According to the Talmud, the Noahide laws apply to all of humanity. In Judaism, the term B'nei Noach (Hebrew: , "Sons of Noah") refers to all mankind. The Talmud also states: "Righteous people of all nations have a share in the world to come". Any non-Jew who lives according to these laws is regarded as one of the righteous among the gentiles. According to the Talmud, the seven laws were given first to Adam and subsequently to Noah. Six of the seven laws were exegetically derived from passages in the Book of Genesis, with the seventh being the establishment of courts of justice.
The Talmudic sages expanded the concept of universal morality within the Noahide laws and added several other laws beyond the seven listed in the Talmud and Tosefta which are attributed to different rabbis, such as prohibitions against committing incest, cruelty to animals, pairing animals of different species, grafting trees of different kinds, castration, emasculation, homosexuality, pederasty, and sorcery among others, with some of the sages, such as Ulla, going so far as to make a list of 30 laws. The Talmud expands the scope of the seven laws to cover about 100 of the 613 mitzvot.
In practice, Jewish law makes it very difficult to apply the death penalty. No record exists of a gentile having been put to death for violating the seven Noahide laws. Some of the categories of capital punishment recorded in the Talmud are recorded as having never been carried out. It is thought that the rabbis included discussion of them in anticipation of the coming Messianic Age.
The Talmud lists the punishment for blaspheming the Ineffable Name of God as death. The sons of Noah are to be executed by decapitation for most crimes, considered one of the lightest capital punishments, by stoning if he has intercourse with a Jewish betrothed woman, or by strangulation if the Jewish woman has completed the marriage ceremonies, but had not yet consummated the marriage. In Jewish law, the only form of blasphemy which is punishable by death is blaspheming the Ineffable Name (Leviticus 24:16). Some Talmudic rabbis held that only those offences for which a Jew would be executed, are forbidden to gentiles. The Talmudic rabbis discuss which offences and sub-offences are capital offences and which are merely forbidden.
Maimonides states that anyone who does not accept the seven laws is to be executed, as God compelled the world to follow these laws. However, for the other prohibitions such as the grafting of trees and bestiality he holds that the sons of Noah are not to be executed. Maimonides adds a universalism lacking from earlier Jewish sources. The Talmud differs from Maimonides in that it considers the seven laws enforceable by Jewish authorities on non-Jews living within a Jewish nation. Nahmanides disagrees with Maimonides' reasoning. He limits the obligation of enforcing the seven laws to non-Jewish authorities, thus taking the matter out of Jewish hands. The Tosafot seems to agree with Nahmanides reasoning. According to some opinions, punishment is the same whether the individual transgresses with knowledge of the law or is ignorant of the law.
Some authorities debate whether non-Jewish societies may decide to modify the Noachide laws of evidence (for example, by requiring more witnesses before punishment, or by permitting circumstantial evidence) if they consider that to be more just.
Various rabbinic sources have different positions on the way the seven laws are to be subdivided in categories. Maimonides', in his Mishneh Torah, included the grafting of trees. Like the Talmud, he interpreted the prohibition against homicide as including a prohibition against abortion. David ben Solomon ibn Abi Zimra, a commentator on Maimonides, expressed surprise that he left out castration and sorcery which were also listed in the Talmud.
The Talmudist Ulla said that here are 30 laws which the sons of Noah took upon themselves. However, he only lists three, namely the three that the gentiles follow: not to create a Ketubah between males, not to sell carrion or human flesh in the market and to respect the Torah. The rest of the laws are not listed. Though the authorities seem to take it for granted that Ulla's thirty commandments included the original seven, an additional thirty laws are also possible from the reading. Two different lists of the 30 laws exist. Both lists include an additional twenty-three mitzvot which are subdivisions or extensions of the seven laws. One from the 16th-century work Asarah Maamarot by Rabbi Menahem Azariah da Fano and a second from the 10th century Samuel ben Hofni which was recently published from his Judeo-Arabic writings after having been found in the Cairo Geniza. Rabbi Zvi Hirsch Chajes suggests Menahem Azariah of Fano enumerated commandments are not related to the first seven, nor based on Scripture, but instead were passed down by oral tradition.
During biblical times, a gentile living in the Land of Israel who didn't want to convert to Judaism but accepted the Seven Laws of Noah as binding upon himself was granted the legal status of ger toshav (Hebrew: ?, ger: "foreigner" or "alien" + toshav: "resident", lit. "resident alien"). A ger toshav is therefore commonly deemed a "Righteous Gentile" (Hebrew: ? , Chassid Umot ha-Olam: "Pious People of the World"), and is assured of a place in the World to Come (Olam Ha-Ba).
The rabbinic regulations regarding Jewish-gentile relations are modified in the case of a ger toshav. The accepted halakhic opinion is that the ger toshav must accept the seven Noahide laws in the presence of three haberim (men of authority), or, according to the rabbinic tradition, before a beth din (Jewish rabbinical court). He will receive certain legal protection and privileges from the Jewish community, and there is an obligation to render him aid when in need. The restrictions on having a gentile do work for a Jew on the Shabbat are also greater when the gentile is a ger toshav.
According to the Jewish philosopher and professor Menachem Kellner's study on Maimonidean texts (1991), a ger toshav could be a transitional stage on the way to becoming a "righteous alien" (Hebrew: , ger tzedek), i.e. a full convert to Judaism. He conjectures that, according to Maimonides, only a full ger tzedek would be found during the Messianic era. Furthermore, Kellner criticizes the assumption within Orthodox Judaism that there is an "ontological divide between Jews and Gentiles", which he believes is contrary to what Maimonides thought and the Torah teaches, stating that "Gentiles as well as Jews are fully created in the image of God".
During the Golden Age of Jewish culture in the Iberian Peninsula, the medieval Jewish philosopher and rabbi Maimonides (1135-1204) wrote in the halakhic legal code Mishneh Torah that gentiles must perform exclusively the Seven Laws of Noah and refrain from studying the Torah or performing any Jewish commandment, including resting on the Shabbat; however, Maimonides also states that if gentiles want to perform any Jewish commandment besides the Seven Laws of Noah according to the correct halakhic procedure, they are not prevented from doing so. According to Maimonides, teaching non-Jews to follow the Seven Laws of Noah is incumbent on all Jews, a commandment in and of itself. Nevertheless, the majority of rabbinic authorities over the centuries have rejected Maimonides' opinion, and the dominant halakhic consensus has always been that Jews are not required to spread the Noahide laws to non-Jews.
Maimonides held that gentiles may have a part in the World to Come (Olam Ha-Ba) just by observing the Seven Laws of Noah and accepting them as divinely revealed to Moses. According to Maimonides, such non-Jews achieve the status of Chassid Umot Ha-Olam ("Pious People of the World"), and are different from those which solely keep the Noahide laws out of moral/ethical reasoning alone. He wrote in Hilkhot M'lakhim:"
Anyone who accepts upon himself and carefully observes the Seven Commandments is of the Righteous of the Nations of the World and has a portion in the World to Come. This is as long as he accepts and performs them because (he truly believes that) it was the Holy One, Blessed Be He, Who commanded them in the Torah, and that it was through Moses our Teacher we were informed that the Sons of Noah had already been commanded to observe them. But if he observes them because he convinced himself, then he is not considered a Resident Convert and is not of the Righteous of the Nations of the World, but merely one of their wise.
Some later editions of the Mishneh Torah differ by one letter and read "Nor one of their wise men"; the latter reading is narrower. In either reading, Maimonides appears to exclude philosophical Noahides from being "Righteous Gentiles". According to him, a truly "Righteous Gentile" follows the seven laws because they are divinely revealed, and thus are followed out of obedience to God.
The 15th-century Sephardic Orthodox rabbi Yosef Caro, one of the early Acharonim and author of the Shulchan Aruch, rejected Maimonides' denial of the access to the World to Come to the gentiles who obey the Noahide laws guided only by their reason as anti-rationalistic and unfounded, asserting that there isn't any justification to uphold such a view in the Talmud. The 17th-century Sephardic philosopher Baruch Spinoza read Maimonides as using "nor", and accused him of being narrow and particularistic. Other Jewish philosophers influenced by Spinoza, such as Moses Mendelssohn and Hermann Cohen, also have formulated more inclusive and universal interpretations of the Seven Laws of Noah.
Moses Mendelssohn, one of the leading exponents of the Jewish Enlightenment (Haskalah), strongly disagreed with Maimonides' opinion, and instead contended that gentiles which observe the Noahide laws out of ethical, moral, or philosophical reasoning, without believing in the Jewish monotheistic conception of God, retained the status of "Righteous Gentiles" and would still achieve salvation. According to Steven Schwarzschild, Maimonides' position has its source in his adoption of Aristotle's skeptical attitude towards the ability of reason to arrive at moral truths, and "many of the most outstanding spokesmen of Judaism themselves dissented sharply from" this position, which is "individual and certainly somewhat eccentric" in comparison to other Jewish thinkers.
A novel understanding of Maimonides' position in the 20th century, advanced by the Ashkenazi Orthodox rabbi Abraham Isaac Kook, is that a non-Jew who follows the commandments due to philosophical conviction rather than revelation (what Maimonides calls "one of their wise men") also merits the World to Come; this would be in line with Maimonides' general approach that following philosophical wisdom advances a person more than following revelatory commands.
Menachem Mendel Schneerson encouraged his followers on many occasions to preach the Seven Laws of Noah, devoting some of his addresses to the subtleties of this code. Since the 1990s, Orthodox Jewish rabbis from Israel, most notably those affiliated to Chabad-Lubavitch and religious Zionist organizations, including The Temple Institute, have set up a modern Noahide movement. These Noahide organizations, led by religious Zionist and Orthodox rabbis, are aimed at non-Jews in order to proselytize among them and commit them to follow the Noahide laws. However, these religious Zionist and Orthodox rabbis that guide the modern Noahide movement, who are often affiliated with the Third Temple movement, are accused of expounding a racist and supremacist ideology which consists in the belief that the Jewish people are God's chosen nation and racially superior to non-Jews, and mentor Noahides because they believe that the Messianic era will begin with the rebuilding of the Third Temple on the Temple Mount in Jerusalem to re-institute the Jewish priesthood along with the practice of ritual sacrifices, and the establishment of a Jewish theocracy in Israel, supported by communities of Noahides. In 1990, Meir Kahane was the keynote speaker at the First International Conference of the Descendants of Noah, the first Noahide gathering, in Fort Worth, Texas. After the assassination of Meir Kahane that same year, The Temple Institute, which advocates to rebuild the Third Jewish Temple on the Temple Mount in Jerusalem, started to promote the Noahide laws as well.
In the 1980s, Menachem Mendel Schneerson urged his followers to actively engage in activities to inform non-Jews about the Noahide laws, which had not been done in previous generations. The Chabad-Lubavitch movement has been one of the most active in Noahide outreach, believing that there is spiritual and societal value for non-Jews in at least simply acknowledging the Noahide laws.
In 1982, Chabad-Lubavitch had a reference to the Noahide laws enshrined in a U.S. Presidential proclamation: the "Proclamation 4921", signed by the then-U.S. President Ronald Reagan. The United States Congress, recalling House Joint Resolution 447 and in celebration of Schneerson's 80th birthday, proclaimed April 4, 1982, as a "National Day of Reflection."
In 1989 and 1990, Chabad-Lubavitch had another reference to the Noahide laws enshrined in a U.S. Presidential proclamation: the "Proclamation 5956", signed by then-U.S. President George H. W. Bush. The United States Congress, recalling House Joint Resolution 173 and in celebration of Schneerson's 87th birthday, proclaimed April 16, 1989, and April 6, 1990, as "Education Day, U.S.A.".
In January 2004, the spiritual leader of the Druze community in Israel, Sheikh Mowafak Tarif, met with a representative of Chabad-Lubavitch to sign a declaration calling on all non-Jews in Israel to observe the Noahide laws; the mayor of the Arab city of Shefa-'Amr (Shfaram) -- where Muslim, Christian, and Druze communities live side-by-side -- also signed the document.
In March 2016, the Sephardic Chief Rabbi of Israel, Yitzhak Yosef, declared during a sermon that Jewish law requires that only non-Jews who follow the Noahide laws are allowed to live in Israel: "According to Jewish law, it's forbidden for a non-Jew to live in the Land of Israel - unless he has accepted the seven Noahide laws, [...] If the non-Jew is unwilling to accept these laws, then we can send him to Saudi Arabia, [...] When there will be full, true redemption, we will do this." Yosef further added: "non-Jews shouldn't live in the land of Israel. [...] If our hand were firm, if we had the power to rule, then non-Jews must not live in Israel. But, our hand is not firm. [...] Who, otherwise be the servants? Who will be our helpers? This is why we leave them in Israel." Yosef's sermon sparked outrage in Israel and was fiercely criticized by several human rights associations, NGOs and members of the Knesset; Jonathan Greenblatt, Anti-Defamation League's CEO and national director, and Carole Nuriel, Anti-Defamation League's Israel Office acting director, issued a strong denunciation of Yosef's sermon:
The statement by Chief Rabbi Yosef is shocking and unacceptable. It is unconscionable that the Chief Rabbi, an official representative of the State of Israel, would express such intolerant and ignorant views about Israel's non-Jewish population - including the millions of non-Jewish citizens.
As a spiritual leader, Rabbi Yosef should be using his influence to preach tolerance and compassion towards others, regardless of their faith, and not seek to exclude and demean a large segment of Israelis.
We call upon the Chief Rabbi to retract his statements and apologize for any offense caused by his comments.
Noahide law differs radically from Roman law for gentiles (Jus Gentium), if only because the latter was enforceable judicial policy. Rabbinic Judaism has never adjudicated any cases under the Noahide laws, Jewish scholars disagree about whether the Noahide laws are a functional part of the Halakha (Jewish law).
Some modern views hold that penalties are a detail of the Noahide Laws and that Noahides themselves must determine the details of their own laws for themselves. According to this school of thought - see N. Rakover, Law and the Noahides (1998); M. Dallen, The Rainbow Covenant (2003) - the Noahide laws offer humankind a set of absolute values and a framework for righteousness and justice, while the detailed laws that are currently on the books of the world's states and nations are presumptively valid.
In recent years, the term "Noahide" has come to refer to non-Jews who strive to live in accord with the seven Noahide Laws; the terms "observant Noahide" or "Torah-centered Noahides" would be more precise but these are infrequently used. Support for the use of "Noahide" in this sense can be found with the Ritva, who uses the term Son of Noah to refer to a gentile who keeps the seven laws, but is not a ger toshav.
In the history of Christianity, the Apostolic Decree recorded in Acts 15 is commonly seen as a parallel to the Seven Laws of Noah. However, modern scholars dispute the connection between Acts 15 and the Noahide laws. The Apostolic Decree is still observed by the Eastern Orthodox Church and includes some food restrictions.
According to Acts 13, 14, 17, 18 [...], Paul began working along the traditional Jewish line of proselytizing in the various synagogues where the proselytes of the gate [e.g., Exodus 20:9] and the Jews met; and only because he failed to win the Jews to his views, encountering strong opposition and persecution from them, did he turn to the gentile world after he had agreed at a council with the apostles at Jerusalem to admit the gentiles into the Church only as proselytes of the gate, that is, after their acceptance of the Noachian laws (Acts 15:1-31)".
The article on the New Testament states:
For great as was the success of Barnabas and Paul in the heathen world, the authorities in Jerusalem insisted upon circumcision as the condition of admission of members into the Church, until, on the initiative of Peter, and of James, the head of the Jerusalem church, it was agreed that acceptance of the Noachian Laws--namely, regarding avoidance of idolatry, fornication, and the eating of flesh cut from a living animal--should be demanded of the heathen desirous of entering the Church.
Noahide Laws, also called Noachian Laws, a Jewish Talmudic designation for seven biblical laws given to Adam and to Noah before the revelation to Moses on Mt. Sinai and consequently binding on all mankind.CS1 maint: extra text: authors list (link)
Beginning with Genesis 2:16, the Babylonian Talmud listed the first six commandments as prohibitions against idolatry, blasphemy, murder, adultery, and robbery and the positive command to establish courts of justice (with all that this implies). After the Flood a seventh commandment, given to Noah, forbade the eating of flesh cut from a living animal (Genesis 9:4). Though the number of laws was later increased to 30 with the addition of prohibitions against castration, sorcery, and other practices, the "seven laws," with minor variations, retained their original status as authoritative commandments and as the source of other laws. As basic statutes safeguarding monotheism and guaranteeing proper ethical conduct in society, these laws provided a legal framework for alien residents in Jewish territory. Maimonides thus regarded anyone who observed these laws as one "assured of a portion in the world to come."
In rabbinic literature the ger toshab was a Gentile who observed the Noachian commandments but was not considered a convert to Judaism because he did not agree to circumcision. [...] some scholars have made the mistake of calling the ger toshab a "proselyte" or "semiproselyte." But the ger toshab was really a resident alien in Israel. Some scholars have claimed that the term "those who fear God" (yir?ei Elohim/Shamayim) was used in rabbinic literature to denote Gentiles who were on the fringe of the synagogue. They were not converts to Judaism, although they were attracted to the Jewish religion and observed part of the law.
Rashi, Yevamot 48b, maintains that a resident alien (ger toshav) is obliged to observe Shabbat. The ger toshav, in accepting the Seven Commandments of the Sons of Noah, has renounced idolatry and [...] thereby acquires a status similar to that of Abraham. [...] Indeed, Rabbenu Nissim, Avodah Zarah 67b, declares that the status on an unimmersed convert is inferior to that of a ger toshav because the former's acceptance of the "yoke of the commandments" is intended to be binding only upon subsequent immersion. Moreover, the institution of ger toshav as a formal halakhic construct has lapsed with the destruction of the Temple.
In order to find a precedent the rabbis went so far as to assume that proselytes of this order were recognized in Biblical law, applying to them the term "toshab" ("sojourner," "aborigine," referring to the Canaanites; see Maimonides' explanation in "Yad," Issure Biah, xiv. 7; see Grätz, l.c. p. 15), in connection with "ger" (see Ex. xxv. 47, where the better reading would be "we-toshab"). Another name for one of this class was "proselyte of the gate" ("ger ha-sha'ar," that is, one under Jewish civil jurisdiction; comp. Deut. v. 14, xiv. 21, referring to the stranger who had legal claims upon the generosity and protection of his Jewish neighbors). In order to be recognized as one of these the neophyte had publicly to assume, before three "?aberim," or men of authority, the solemn obligation not to worship idols, an obligation which involved the recognition of the seven Noachian injunctions as binding ('Ab. Zarah 64b; "Yad," Issure Biah, xiv. 7). [...] The more rigorous seem to have been inclined to insist upon such converts observing the entire Law, with the exception of the reservations and modifications explicitly made in their behalf. The more lenient were ready to accord them full equality with Jews as soon as they had solemnly forsworn idolatry. The "via media" was taken by those that regarded public adherence to the seven Noachian precepts as the indispensable prerequisite (Gerim iii.; 'Ab. Zarah 64b; Yer. Yeb. 8d; Grätz, l.c. pp. 19-20). The outward sign of this adherence to Judaism was the observance of the Sabbath (Grätz, l.c. pp. 20 et seq.; but comp. Ker. 8b).
against my reading of Maimonides is strengthened by the fact that Maimonides himself says that the ger toshav is accepted only during the time that the Jubilee is practiced. The Jubilee year is no longer practiced in this dispensation [...]. Second, it is entirely reasonable to assume that Maimonides thought that the messianic conversion of the Gentiles would be a process that occurred in stages and that some or all Gentiles would go through the status of ger toshav on their way to the status of full convert, ger tzedek. But this question aside, there are substantial reasons why it is very unlikely that Maimonides foresaw a messianic era in which the Gentiles would become only semi-converts (ger toshav) and not full converts (ger tzedek). Put simply, semi-converts are not separate from the Jews but equal to them; their status is in every way inferior and subordinate to that of the Jews. They are separate and unequal.
the basic philosophical reason which compelled Maimonides to take this restrictive position toward the Noachides was the fact that he had learned from his teacher Aristotle and was ready also for religious reasons to believe that ethics are not a purely rational, philosophic or scientific discipline. Only the barest outline of general ethical principles can be defined by logical methods. The substance of the matter which resides in its details can be obtained only through positive statutes, traditions, or divine commands, none of which are produced by conscious, rational processes
