No one knows who those churches are today. You are asking a question un answerable.
That is why Paul left being a Phasrisee! He went back to Torah law.
Romans 2:13. Acts 24:14.
When you read Paul say things as in Galatians 3:11 or Ephesians 2:8-9 he is referncing works of law which is religion not THE LAW.
Paul was sent to explain the differences in oral jewish law and the written torah law. People do not get this and think Paul started Christianity.
Why do you assume he means Christians?He does not.
He means people who follow the law can be grafted to the tree of the people who left the law. Gods future assembly is of all people.
Again when Pauls says "law" you naturally ASSUME he means Torah. Not true. When he condemns the law he is condemning Jewish law. Paul talks about 2 sets of Laws not 1.
Did you read Acts 24:14? Did you read Romans 2:13?
99% of Christians do not get Paul.
You read but you do not comprehend.
Acts 15:20 and 29 ARE LAWS THEY GAVE THEM. 4 starter laws.
Acts 21 you need all the verses. They were talking about should a gentile becomme a Jew.
Paul never taught to eat unclean meats. You do not understand what he is saying.
Galatians 3:11??? look it up and tell me why that is not in conflict with Romans 2:13.
Again you do not get Paul's message at all.
Paul had NOTHING to do with Christianity.
The word FULFLILL does not mean to take away or make moot as you christians have been erroneously taught. It means to display or make full.
READ THE VERY NEXT VERSES MAtthew 5:18. Until ALL IS DONE not 1 jot or tittle of the law is removed. IF there was no Law no one would be a sinner for sin is breaking the law. 1john 3:4 NT
