Having studied quite a few articles and responsa on how a non-Jew is to relate to the Torah I think it would be nice to present some opinions. Especially since there seems to be quite some confusion on the internet as to a non-Jew’s relationship to the Torah and most discussions omit proper reference to the sources in the Jewish legal tradition. Credit for locating and teaching me all these sources goes to a good friend who is far more knowledgeable than I am.
Alot of halachic questions start with the Rambam and so will this post, specifically Hilchot Melachim Ch. 10:
The Rambam in Hilchot Melachim 10:9 says as following:
עכו”ם שעסק בתורה חייב מיתה. לא יעסוק אלא בשבע מצות שלהן בלבד. וכן עכו”ם ששבת אפילו ביום מימות החול. אם עשאהו לעצמו כמו שבת חייב מיתה. ואין צריך לומר אם עשה מועד לעצמו. כללו של דבר אין מניחין אותן לחדש דת ולעשות מצות לעצמן מדעתן. אלא או יהיה גר צדק ויקבל כל המצות. או יעמוד בתורתו ולא יוסיף ולא יגרע. ואם עסק בתורה. או שבת. או חדש דבר. מכין אותו ועונשין אותו. ומודיעין אותו שהוא חייב מיתה על זה אבל אינו נהרג
“An idol-worshipper that engages in Torah is liable to the death penalty. He should not engage [in the Torah] except for the 7 mitzvot alone. Similarly an idol-worshipper that rests even on a weekday. If he makes it to himself like a Shabbat he is liable to the death penalty. And its not necessary to say [that] if he makes it a festival to himself [it is also prohibited]. The general principle is that we dont allow him to invent religion and to do commandments that he made up. Rather either he becomes a convert and accepts all of the commandments. Or he stands in his Torah and does not add nor subtract. And if he engages in Torah or in Shabbat or invents a new thing, we lash him and punish him, and inform him that he is liable to the death penalty on this account but we dont kill him.”
In Hilchot Melachim 10:10, the very next halacha, he writes:
בן נח שרצה לעשות מצוה משאר מצות התורה כדי לקבל שכר. אין מונעין אותו לעשות כהלכתה. ואם הביא עולה מקבלין ממנו. נתן צדקה מקבלין ממנו. ויראה לי שנותנין אותה לעניי ישראל. הואיל והוא ניזון מישראל ומצוה עליהם להחיותו. אבל העכו”ם שנתן צדקה מקבלין ממנו ונותנין אותה לעניי עכו”ם
“A son of Noah that wants to do a commandment from the rest of the commandments of the Torah (i.e. other than the 7) in order to obtain reward, we dont prevent him to do so according to the halacha. And if he brought a sacrifice we accept it from him. If he gave charity, we accept it from him. And it appears to me that we give it to the poor of Israel. Since he is fed by Israel and we are commanded to sustain him. But an idol-worshipper that gave charity we accept it from him and give it to poor idol-worshippers.”
On these two halachot alot has been written and Ill try to give a glimpse in this post. It needs to be said that these arguments are often quite difficult and only come to their full force when read in their entirety. Hence if you are interested in learning more about this you would do well to look up the sources yourself.
There is an obvious discrepancy between the two halachot, in the one the Rambam seems to forbid any additional commandments while in the other he seems to allow it and even says theres reward for doing them.
The Radbaz, in his commentary to the Rambam solves the discrepancy as following:
ואם רצה לעשות באומרו שנצטוה עליה אין מניחין אותו לעשותה אלא אם עשאה כדי לקבל עליה שכר כמי שאינו מצווה ועושה וכן דקדק רבינו וכתב כדי לקבל שכר. ומ”מ במצות שצריכין קדושה וטהרה כגון תפילין ס”ת ומזוזה אני חוכך להחמיר שלא יניחו אותם לעשותן
“And if he wants to do [the additional commandments] while saying that it was commanded to them we dont allow him to do [them] rather if he does them in order to obtain reward like one who is not commanded but does [we allow it], and thus our master was precise and wrote “in order to obtain reward”. Nevertheless regarding the commandments that require holiness and purity like Tefilin, Torah scrolls and Mezuzah I argue to be stringent that they should not allow them to do them.”
So according to the Radbaz halacha 9 applies to one that thinks he is obligated to do certain additional commandments, while halacha 10 applies to one who realizes he is not obligated to do these additional comandments but nevertheless aspires to them in order to obtain reward.
The Avnei Shoham disagrees with the Radbaz and says this distinction on basis of intention is not found anywhere in halacha, and in addition to this he argues that this distinction could not explain the situation of Avraham Avinu, who is said to have kept the whole Torah but certainly did not act for reward. He reads the Rambam in a different way: halacha 9 refers to a person who does commandments he made up himself while halacha 10 refers to a person who does commandments that are among the 613. This is why the Rambam wrote in halacha 9 “we dont allow him to invent religion and to do commandments that he made up” while in halacha 10 he wrote “a commandment from the rest of the commandments of the Torah”. According to the Avnei Shoham, exceptions to this rule are engaging in Torah, keeping Shabbat and sacrifices other than the burnt offering.
R. Moshe Feinstein explains the Rambam in a very different way; he says a non-Jew has no possibility to do any additional commandments at all (except for bringing certain sacrifices and giving charity) and thus theres no reward either. In his opinion by saying “in order to obtain reward” the Rambam is not conceding that non-Jews get reward on additional commandments but is just explaining the intention of the non-Jew (which is false). Interestingly in another teshuva of his on whether non-Jews are commanded in prayer he does seem to agree with the Radbaz’s reading and says non-Jews can voluntarily pray when not in distress (which is optional to them) and get reward for it like one who is not commanded but does.
The Chatam Sofer comes to a very different conclusion, he says:
ועיין רמב”ם פ׳ יוד ממלכים ה׳ ט׳ וה׳ יוד שנראה שמחלק בין עכו״ם לבן נח שאותו קיבל עליו שלא לעע״ז וזה מותר לשבות ולקיים המצות שירצה ומזה מקבלים קרבנות ומלמדים לו תורה ומקבלים ממש צדקה והשתא לק״מ מגוי ששבת מי איכא מידי דהרי גם גוי אם אינו עע״ז מותר לשבות
“And see the Rambam in Hilchot Melachim 10:9 and :10, that it appears that he distinguishes between an idol-worshipper and a son of Noah, that one accepted on himself not to worship idols and to this one its permitted to rest (keep Shabbat) and to fulfill the commandments that he desires and from him we accept sacrifices and we teach him Torah and accept literally from him charity and now there is no question at all from the case of a non-Jew that rests on Shabbat — is there any problem? — since behold also a non-Jew, if he does not worship idols is allowed to rest on Shabbat.”
So the Chatam Sofer thinks the discrepancy can be solved by focusing on the word that is used by the Rambam in referring to non-Jews. In halacha 9 its ‘idol-worshipper’ while in halacha 10 its ‘son of Noah’. To be sure the Rambam is careful with his wording so this might be the solution, however R. Twersky notes that in the Rambam’s teshuva regarding whether a Jew can circumcize a non-Jew he does not distinguish between idol-worshipper or son of Noah
It is quite striking though that the Chatam Sofer goes as far as saying that a non-Jew that accepts the 7 commandments can perform any additional commandment he desires
Arriving at a similar conclusion from a very different angle is the Chemdat Yisrael, who explains the prohibition of Shabbat observance for non-Jews in the following way: in Rabbinic literature we find the idea that there is no astrological influence on Israel but there is on the nations. The Abarbanel explains this as the reason why Jews are not allowed to ascribe power to any other thing than God (as He is the only influence in their lives). Therefore since Jews are exclusively devoted to God, and since God rests on Shabbat, they are required to rest as well. Non-Jews however, are allowed to ascribe influence to other beings in addition to God since they are under the influence of the stars/spheres. These stars/spheres are however in continual movement, therefore non-Jews are not allowed to rest either. If you are already as uncomfortable as I am was when reading this, bear with the Chemdat Yisrael a bit more: if a non-Jew were to commit himself exclusively to God, and ascribe influence to Him alone, it would be allowed and even fitting (!) for him to rest on Shabbat like his Maker does.
As with anything in Judaism, there are more opinions on the matter but I think this gives a nice glimpse into how several poskim (jewish legal decisors) have dealt with our topic. I think this also provides a good reminder not to take answers limited to ‘yes’ or ‘no’ at face value, theres a whole chain of thought linked to these answers which if omitted will certainly yield the wrong impression. Like I said before, this blogpost should only be a glimpse of this process but the serious student will take this is as a springboard into greater study.
I also think this shows that there is real room for non-Jews to relate to the God of Israel beyond the mere bones of the 7 categories, though there is no pressure in doing so. Furthermore, an understanding of these provisions yields in my opinion a picture of great inclusiveness and sensitivity to the needs and abilities of mankind who is created in the image of God.
