Sorry but Paul stayed away from Jerusalem for 14 years after his conversion.
Not entirely true as we see in Acts 15 and 20
And immediately after the Acts 15 meeting what is the "very next thing" Paul does? --
answer: Paul convinces Timothy to be circumcised.
And in Acts 20 - what is the argument made to Paul - what is he supposed to "prove" and what is he "refuting" ?
Acts 20
17 After
we arrived in Jerusalem, the brethren received us gladly. 18 And the following day Paul went in with us to James, and all the elders were present. 19 After he had greeted them, he
began to relate one by one the things which God had done among the Gentiles through his ministry. 20 And when they heard it they
began glorifying God; and they said to him, “
You see, brother, how many thousands there are among the Jews of those who have believed, and they are all
zealous for the Law; 21 and they have been told about you, that you are teaching all the Jews who are among the Gentiles to forsake Moses, telling them not to circumcise their children nor to walk according to the customs. 22 What, then, is
to be done? They will certainly hear that you have come. 23 Therefore do this that we tell you. We have four men who are under a vow; 24 take them and
purify yourself along with them, and pay their expenses so that they may shave their heads;
and all will know that there is nothing to the things which they have been told about you, but that you yourself also walk orderly, keeping the Law
And how about after that?
In Acts 23?
6 But perceiving that one group were Sadducees and the other Pharisees, Paul began crying out in the Council, “Brethren, I am a Pharisee, a son of Pharisees; I am on trial for the hope and resurrection of the dead!” 7 As he said this, there occurred a dissension between the Pharisees and Sadducees, and the assembly was divided. 8 For the Sadducees say that there is no resurrection, nor an angel, nor a spirit, but the Pharisees acknowledge them all. 9 And there occurred a great uproar; and some of the scribes of the Pharisaic party stood up and began to argue heatedly, saying, “We find nothing wrong with this man; suppose a spirit or an angel has spoken to him?”
Hebrews 10:4-12 says that the system of animal sacrifices and offerings ended at the cross - but when you go out on a limb to speak of what Paul's practice was - you need to be accurate and careful in what you say about that specific Bible detail.
