Anyone that can read can see that the argument for or against keeping the law was satisfied in Acts 15. After all that is why Paul came to the 12.
Those Jews who believed Jesus was their Messiah and King were going out behind Paul and saying that the Gentiles had to keep the law ( just like some on this forum are saying). That is the very reason for the meeting between Paul and the 12. But the religious love the law because they can tell others how they are better than them. That is where their pride leads them.
Here it is, read it for yourselves.
Acts 15:22-29 ---- The Jerusalem Decree
22 Then it pleased the apostles and elders, with the whole church, to send chosen men of their own company to Antioch with Paul and Barnabas, namely, Judas who was also named Barsabas, and Silas, leading men among the brethren.
23 They wrote this, letter by them: The apostles, the elders, and the brethren,
To the brethren who are of the Gentiles in Antioch, Syria, and Cilicia:
Greetings.
24 Since we have heard that some who went out from us have troubled you with words, unsettling your souls, saying, "You must be circumcised and keep the law" — to whom we gave no such commandment —
25 it seemed good to us, being assembled with one accord, to send chosen men to you with our beloved Barnabas and Paul,
26 men who have risked their lives for the name of our Lord Jesus Christ.
27 We have therefore sent Judas and Silas, who will also report the same things by word of mouth.
28 For it seemed good to the Holy Spirit, and to us, to lay upon you no greater burden than these necessary things:
29 that you abstain from things offered to idols, from blood, from things strangled, and from sexual immorality. If you keep yourselves from these, you will do well. Farewell.
NKJV
