It is not obvious. Why? Because we NEVER see in Acts or in the epistles of Peter, John, James, Jude to do such things. Where in Acts do we see commands to follow the ceremonial law and to circumsize? We don't. Error had crept in the Jerusalem church as they incorporated more Jews especially some Pharisees. Some may have been practicing some of the old ways but none of he apostles were preaching them as a way to salvation or a requirement.
Acts 15:1 And certain men which came down from Judaea taught the brethren, and said, Except ye be circumcised after the manner of Moses, ye cannot be saved. 2 When therefore Paul and Barnabas had no small dissension and disputation with them, they determined that Paul and Barnabas, and certain other of them, should go up to Jerusalem unto the apostles and elders about this question.
Who had taught those “certain men”? It couldn’t have been Paul since it was he who had the “dissension” with. It had to have been from the other 12. Unless you know of someone other than they who were preaching the gospel of Jesus. Regardless of whether that teaching had “crept in” from someone else it’s clear to me that the 12 didn’t teach particularly against it but Paul did or he wouldn’t have had the “dissention”.
They all started out in the church following all the laws...And there wasn't a clear statement on revoking the law until Romans 3...

I don't think it was error...Bible says it was fear...Seems as Peter was well outnumbered by the Jewish Christians and he lacked the courage to stand up to them to tell them the truth...He was in great fear...And Barnabas became gripped with the same fear...
