I just wondered what the difference is between Jewish and Messianic Jewish belief of the Noahide Laws and the belief towards non-Jews if anything and what laws they must keep?
Why do many mainstream Jews believe non-Jews should be prohibited from keeping the Torah (old testament)?
Does this belief actually come from the Torah itself and thus God or is it from Jewish law & tradition e.g. the Talmud?
If it is the case that non-Jews only need to keep the 7 Noahide laws why not Jews only keep these 7 too?
Also why do some authorities add, or extend the 7 Laws to include additional prohibitions or thing you must do. E.g. Against mixing species of seeds or animals, castration, sorcery, and giving to charity?
If the Noahide laws is Jewish belief of a way for non-Jews to get to Heaven, why do they need to add to these laws and expand on them to include essentially other Torah commandments?
To get to heaven? I did not think Judaism taught much on the next life. Noachide law was more about Gentiles which were righteous being counted as sons of Noah.
Ge 6:18 But with thee will I establish my covenant; and thou shalt come into the ark, thou, and thy sons, and thy wife, and thy sons wives with thee.
Ge 9:9 And I, behold, I establish my covenant with you, and with your seed after you;
Why is it forbidden for non-Jews to keep the Ten Commandments or the full 613 commandments of the Torah? Where does God say this in the Torah that it is only for Jews? Or does this just come from the Talmud and Jewish tradition and not from God?
Ex 12:48 And when a stranger shall sojourn with thee, and will keep the passover to the LORD,
let all his males be circumcised, and then let him come near and keep it; and he shall be as one that is born in the land: for no uncircumcised person shall eat thereof.
Didn't God give the Commandments to all Israel not just the Jews? E.g. not just the three tribes, Judah, Levi and Benjamin?
God made the covenant with the ten. But Levites were given certain laws distinct from the common Israelite as well. Not any Jew or Israelite was commanded to perform law given to the Levites. Therefore it is not an odd idea that the law contains commandments for distinct person's to perform.
Do mainstream Jews only believe the law came into existence at Mount Sinai when Moses came down with the stone tablets written by the hand of God? Was the Sabbath not instituted at Creation and in effect from then? There were no Jews back then.
Why does the Bible show righteous Gentiles keeping Sabbath with Jews and praying, teaching, learning in the Temple? Why did Samarians keep Sabbath?
They were teaching Noachide law to the God fearers. This being a legal religious class of Gentile may have been afforded an exemption from Idol's under Roman law.
Finally, do the Noahide Laws really exist? I've looked for them in the Bible but am unable to find them.
In what
form are you expecting to find them?
An example of God's Law being a common judgement upon all is best seen in these verses IMO.
Lev 18:1 And the LORD spake unto Moses, saying,
Ge 18:25 That be far from thee to do after this manner, to slay the righteous with the wicked: and that the righteous should be as the wicked, that be far from thee:
Shall not the Judge of all the earth do right?
Note that these are the things which God judged the nations, for defiling themselves and the land. He spew them out because of these things (see vs 24-25 & 27-28)
Lev 18:1 And the LORD spake unto Moses, saying,
2 Speak unto the children of Israel, and say unto them, I am the LORD your God.
3 After the doings of the land of Egypt, wherein ye dwelt, shall ye not do: and after the doings of the land of Canaan, whither I bring you, shall ye not do: neither shall ye walk in their ordinances.
4 Ye shall do my judgments, and keep mine ordinances, to walk therein: I am the LORD your God.
5 Ye shall therefore keep my statutes, and my judgments: which if a man do, he shall live in them: I am the LORD.
7 The nakedness of thy father, or the nakedness of thy mother, shalt thou not uncover: she is thy mother; thou shalt not uncover her nakedness.
8 The nakedness of thy fathers wife shalt thou not uncover: it is thy fathers nakedness.
9 The nakedness of thy sister, the daughter of thy father, or daughter of thy mother, whether she be born at home, or born abroad, even their nakedness thou shalt not uncover.
10 The nakedness of thy sons daughter, or of thy daughters daughter, even their nakedness thou shalt not uncover: for theirs is thine own nakedness.
11 The nakedness of thy fathers wifes daughter, begotten of thy father, she is thy sister, thou shalt not uncover her nakedness.
12 Thou shalt not uncover the nakedness of thy fathers sister: she is thy fathers near kinswoman.
13 Thou shalt not uncover the nakedness of thy mothers sister: for she is thy mothers near kinswoman.
14 Thou shalt not uncover the nakedness of thy fathers brother, thou shalt not approach to his wife: she is thine aunt.
15 Thou shalt not uncover the nakedness of thy daughter in law: she is thy sons wife; thou shalt not uncover her nakedness.
16 Thou shalt not uncover the nakedness of thy brothers wife: it is thy brothers nakedness.
17 Thou shalt not uncover the nakedness of a woman and her daughter, neither shalt thou take her sons daughter, or her daughters daughter, to uncover her nakedness; for they are her near kinswomen: it is wickedness.
18 Neither shalt thou take a wife to her sister, to vex her, to uncover her nakedness, beside the other in her life time.
19 Also thou shalt not approach unto a woman to uncover her nakedness, as long as she is put apart for her uncleanness.
20 Moreover thou shalt not lie carnally with thy neighbours wife, to defile thyself with her.
21 And thou shalt not let any of thy seed pass through the fire to Molech, neither shalt thou profane the name of thy God: I am the LORD.
22 Thou shalt not lie with mankind, as with womankind: it is abomination.
23 Neither shalt thou lie with any beast to defile thyself therewith: neither shall any woman stand before a beast to lie down thereto: it is confusion.
24 Defile not ye yourselves in any of these things: for in all these the nations are defiled which I cast out before you:
25 And the land is defiled: therefore I do visit the iniquity thereof upon it, and the land itself vomiteth out her inhabitants.
27
(For all these abominations have the men of the land done, which were before you, and the land is defiled
28 That the land spue not you out also, when ye defile it, as it spued out the nations that were before you.
29 For whosoever shall commit any of these abominations, even the souls that commit them shall be cut off from among their people.
30 Therefore shall ye keep mine ordinance, that ye commit not any one of these abominable customs, which were committed before you, and that ye defile not yourselves therein: I am the LORD your God.
It is pretty clear God's Judgement on these things concerned everyone. These things were before Levitical law, and the Sinai covenant. Levitical law is in
addition as Levitical law
retained these judgments. The latter law did not disannul prior judgment so to speak.
