Acts 21 proves that the Apostle Paul was a false teacher

All in bold. In the book of Acts, James (the apparent speaker) makes this statement to Paul: "You see, brother, how many myriads of Jews there are who have believed, and they are all zealous for the law; but they have been informed about you that you teach all the Jews who are among the gentiles to forsake Moses, saying that they ought not to circumcise their children nor to walk according to the customs" (Acts 21:20-21). James here is making a statement that is profoundly important. He, among other apostles, stayed behind in Jerusalem to preach the Gospel of Jesus to all who would listen and here he is referring to the Jews who did believe in Jesus. The believers in the Christ, under their teaching, were “zealous for the law” and James is happy about it, praising their actions. Not only that, but what is going on here is that Paul was summoned to this council in Jerusalem to defend himself of the claims that he is teaching Jews as well as the gentiles to forsake the law. Why would James even talk like this if he agreed with Paul about the law? He is, in fact, giving Paul the opportunity to kill these rumors that he is really teaching people that the law is now unnecessary. We know that Paul had told the Galatians: "Indeed, I Paul say to you that if you become circumcised, Christ will profit you nothing." (Note: Circumcision was the outer sign that one had accepted and agreed to keep the law given to Moses. By being circumcised, a person was agreeing to enter into a covenant with the God of Israel.) "And I testify again to every man who becomes circumcised that he is a debtor to keep the whole law. You have become estranged from Christ, you who attempt to be justified by law; you have fallen from grace..." (Galatians 5:2-6). Paul had many things nice to say about the law but let's focus on his other statements like: "Now that faith has come, we are no longer under the supervision of the law" (Galatians 3:25). " We are now rid of the Law ... free to serve in the new spiritual way and not the old way of a written law" (Romans 7:6). Paul actually told the Galatians that the law was a curse (Gal: 3:13). Paul's teaching about the law were so crystal clear, nearly every mainline denomination today agrees with him - that you can become a child of God not be keeping the law but by faith. So what's the problem, you ask? If Paul was really hearing from God who inspired all of his teachings, why did God not reveal this highly important information to the elders in Jerusalem? Why was Paul being questioned on what he taught about the law because according to Acts 21, the writer is bragging to Paul that the converted Jews there in Jerusalem were "zealous for the law." It seems that they were teaching a different gospel than the one Paul taught and Paul did not have the guts to condemn them for it to their faces despite him warning his congregations about different gospels. It is not my opinion that Paul taught a different gospel. It is what Acts 21 is all about. James and the other apostles were challenging and testing Paul's teachings. It gets worse. James proceeds to tell Paul: " Take these men, join in their purification rites and pay their expenses, so that they can have their heads shaved. Then everybody will know there is no truth in these reports about you, but that you yourself are living in obedience to the law" (Acts 21:24). Do you notice that James wants Paul to PROVE that he is living "in obedience to the law" by participating in this Nazarite vow (book of Numbers). Notice that James never ever echoes Paul’s feelings about the law being a burden and impossible to keep. Paul never says that one’s faith and faith alone can lead one to salvation. He does not take the opportunity to explain to the law-keeping Jewish believers that what they are doing by circumcising and trying to keep the law that they are wrong or in danger of not being saved. This is what Christians today teach. Paul participated in this ritual with offering (Acts 21:26).
