That is fine. I know many Christians who disagree with me on this. But I do think Paul was in error here. Had he done so on his own desire I think it would be different. But he was motivated by James to do this in order to show "that thou thyself also walkest orderly, and keepest the law." (Acts 21:24) Also, I do not think Paul would be correct in following the Law on his own, even if he is a Jew.
It is true with Timothy in that it was Pauls decision to have him circumcised to remove any barrier from the Jews. But when Titus was compelled by the Jews to be circumcised, then Paul refused. (Gal.2:3) "But neither Titus, who was with me, being a Greek, was compelled to be circumcised:"
So because James was motivating Paul to do this to prove that he keeps the law, I believe he was wrong in doing it. And actually I believe Paul was wrong in going to Jerusalem in the first place as God had warned him not to go earlier. (Acts 22:17-18) "And it came to pass, that, when I was come again to Jerusalem, even while I prayed in the temple, I was in a trance; And saw him saying unto me, Make haste, and get thee quickly out of Jerusalem: for they will not receive thy testimony concerning me."
