1. . Ephesus had been part of the Roman Empire for over a century.
2. It was a city second only to Rome in size, almost 500,000 inhabitants.
3. The large temple of Artemis generated jobs for local statue makers and Paul caused some controversy among them Acts 19:23-41)
4. There is no report of a dispute between Paul and the church of the Ephesians.
5. There was an apparent dispute between Jews who thought all Christians should become Jews first and adopt Jewish habits, versus Gentiles who wanted to worship Christ without becoming Jews.
2. One compromise is that a non-Jew who becomes noahide “children of noah” was OK.
3. Noahs laws are for all people

Noahide 7 laws
1. Prohibition of Idolatry: You shall not have any idols before God.
2. Prohibition of Murder: You shall not murder. (Genesis 9:6)
3. Prohibition of Theft: You shall not steal.
4. Prohibition of Sexual Promiscuity: You shall not commit any of a series of sexual prohibitions, which include adultery, incest, bestiality and male homosexual intercourse.
5. Prohibition of Blasphemy: You shall not blaspheme God's name.
6. Dietary Law: Do not eat flesh taken from an animal while it is still alive. (Genesis 9:4)
7. Requirement to have just Laws: You shall set up an effective judiciary to enforce the preceding six laws fairly.

The takeaway is that we are one church and Christ expects us to overlook differences. In general, this is a dispute long lost to history. Few Christians urge death to other Christians with different dogma.

Also, always look for different sets of laws, 10 commandments, all the Leviticus laws, Greek Jewish laws, Paul’s lists of virtues. It is very common for a Christian group to define itself by its laws.
