Please, don't be a noahide.
real commandment observant Christianity.
Maybe you should read the book?
Acts15:17: That the residue of men might seek after the Lord, and all the Gentiles, upon whom my name is called, saith the Lord, who doeth all these things.
18: Known unto God are all his works from the beginning of the world.
This is the foreword of the laws that Paul gave to the gentiles.G-d's works from the beginning of the world includes laws that man must live by.Cain broke one of these laws by murdering his brother and was punished.If these basic laws did not exist,then what law did Cain break?What sin did he commit?
19: Wherefore my sentence is, that we trouble not them, which from among the Gentiles are turned to God:
Verse 19 shows the decision of James that gentiles are not bound to the Torah laws.This is further elaborated in verse 24,where it says "to whom we gave no such commandment"
20: But that we write unto them, that they abstain from pollutions of idols, and from fornication, and from things strangled, and from blood.
1Tim5

Against an elder receive not an accusation, but before two or three witnesses.
A definate reflection that it requires two or more witnesses to convict a man.In Torah law,there must be no less than two witnesses.This is part of the original 7 laws to establish courts of justice.
Rom:13

For this, Thou shalt not commit adultery, Thou shalt not kill, Thou shalt not steal, Thou shalt not bear false witness, Thou shalt not covet; and if there be any other commandment, it is briefly comprehended in this saying, namely, Thou shalt love thy neighbour as thyself.
This is a reflection of what Hillel wrote 100 yera sprior to Paul and 40 years prior to Jesus,"What you dislike yourself,do not do unto your neighbor".It also reconfirms the Noahide laws listed below.
Eph:4:28: Let him that stole steal no more: but rather let him labour, working with his hands the thing which is good, that he may have to give to him that needeth.
Is the fist part of the Noahide laws
The Seven Noachide Laws
====================================
1) It is forbidden to eat a limb or any meat that was
severed from a live animal.<-- prohibition of eating blood,
Acts 15:20. But that we write unto them, that they abstain from pollutions of idols, and from fornication, and from things strangled, and from blood.
2) It is forbidden to blaspheme the name of G-d.
3) It is forbidden to steal or rob.<-- Eph4:28,Rom:13

9. For this, Thou shalt not commit adultery, Thou shalt not kill, Thou shalt not steal, Thou shalt not bear false witness, Thou shalt not covet; and if there be any other commandment, it is briefly comprehended in this saying, namely, Thou shalt love thy neighbour as thyself.
4) It is obligatory to appoint judges and set up a
court of law in order to pronounce and mete out
just decisions to all mankind.<-- 1Tim5:19 19. Against an elder receive not an accusation, but before two or three witnesses.
5) It is forbidden to worship idols. <- No idols,Acts15:20, But that we write unto them, that they abstain from pollutions of idols, and from fornication, and from things strangled, and from blood.
6) It is forbidden to commit sexual sins
(adultery, homosexuality, bestiality).<- No fornication,Acts15:20,Rom:13

For this, Thou shalt not commit adultery,...
7) It is forbidden to murder a human being.Rom:13

For this, .....Thou shalt not kill, ..It is already established earlier that the Torah laws were not to be followed by the gentiles,yet these laws,which are the Noahide laws also contained in Torah were to be followed by the gentiles as taught by Paul.
When meat is prepared at your local market,it is not salted and soaked to remove the blood.Matter of fact,many products list blood as an ingredient such as scrapple,polish liver sausage and others.Hence christians do eat blood.Acts 15:20,29 and Acts21:25
The command not to eat a strangled animal is dirrectly tied to not eating the limb of a living animal.The stun method used in non-kosher slaughter frequently leaves the animal still living when they begin to eviserate and cut it up.A strangled animal was often simply unconciencous in the old days.Acts15:20,29 and Acts 21:25
Have a cross at church that people kneel before to pray?This falls into the graven image catagory,never mind paintings of saints and Jesus,same idea.Acts15:20,29
The church has driven Jews from thier homes to take thier property and pocessions for over 1800 years.Refer to Thou shall not steal and covet,Eph4:28,Rom:13

For this,..... Thou shalt not steal, .... Thou shalt not covet Now,I have heard the old standard of "They weren't real christians" yet they were the only christians.Adherring to the words and proclamations of the church and leaders.
So,the church has consistantly broken the laws they were instructed to obey,almost since its inception.If as John states in 1Jn

4( Whosoever committeth sin transgresseth also the law: for sin is the transgression of the law),the church transgresses these laws on purpose.According to Paul,salvation is lost due to sinning purposely,Hebrews10

For if we sin wilfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins,
27: But a certain fearful looking for of judgment and fiery indignation, which shall devour the adversaries.
Hence,the church has led all of its followers astray from what was taught.
