Paul seems to be confused about circumcision. Paul and Barnabas went up to Jerusalem to figure out this matter.(Acts 15:2.) Some people at the gathering said the gentiles needed to be circumcised.(Acts 15:5.) In the end, they decided that Gentiles did not need to be circumcised, they only needed to follow four commands: Abstain
Paul knows that Gentile converts do not need to be circumcised. Unfortunately, Paul met Timothy directly after these events.
Why did Paul circumcise Timothy? There was no reason for it. Paul knew there was no reason for it. He was just in Jerusalem for the specific purpose of learning what actions Gentiles needed to take. Circumcision was not one of them. But Paul still circumcised Timothy!
Furthermore, in his letter to the church in Galatia, Paul seems to complain that Titus was not forced to be circumcised.
So Paul, by his own actions, and by his own words, circumcised Timothy, then said that Jesus will profit him nothing! What an evil action it was for Paul to circumcise Timothy, because, according to himself, he made Jesus's death of null effect to Timothy.
Value of this Evidence
This is fantastic evidence that Paul is a false apostle. He cannot keep his own doctrine straight. First, he believes that all must be circumcised, then he believes that those circumcised are "debtors to the whole law." That would not be a problem, but Paul also believes that Jesus has abolished the whole law! He must be a very confused individual.
