I'm still thinking about the Jerusalem Council because I would like to finally make sense of this thing. I'll be brief. What about this?
1. Jerusalem Church had a mission to the Gentiles. The desirable conversion was with circumcision although some leniency with regard to food laws (Peter). But there were some who wanted to remain uncircumcised (Stephen). The center of this mission becomes Antioch, but it was a satellite of Jerusalem remaining under its watchful eye. This uncircumcised mission is never safe. It has problems from the beginning and brought about Stephen's martyrdom and the persecution of Christians which Saul took part in.
2. Paul becomes part of this mission after a revelatory experience. When he goes to Jerusalem the first time, he meets with Peter and James (Galatians 1:18-20).
3. The persecution of the uncircumcised mission continues (cf. Galatians 2:4). So Paul makes a second trip to Jerusalem initiated by a revelatory experience to discuss the mission with Peter and James. He takes Titus. And it is agreed that Paul could continue his mission to the uncircumcised, while Peter spearheaded the mission to the circumcised (Galatians 2:1-10).
4. Peter is arrested and James son of Zebedee is killed (Acts 12:1-3). This may be the result of a continued persecution of the Christians for supporting a mission to the uncircumcised. So James finally makes a ruling that the Gentiles must be circumcised and he sends envoys to Antioch to carry this out (Acts 15.1-3; cf. Galatians 6:12-13).
5. When the envoy arrives after Peter gets there (Galatians 2:11-14), there is a dispute over tablefellowship and circumcision (the circumcision party is "feared"). Paul cannot understand the decision from Jerusalem and finds Peter's behavior that of a hypocrite.
6. Paul becomes his own missionary to Asian and Grecian churches.
7. James is forced to make a ruling on food laws now, which he does (in Paul's absence) (Acts 21:25; Acts 15). James never rules that the Gentiles don't need to be circumcised. This is the Jerusalem Council.
8. James sends missionaries out to the Antiochean mission churches in Asia and Greece, to circumcise the Gentiles and relate the Noahide ruling. Paul combats this.
9. James writes the epistle of James and sends it out to the churches to combat Paul.
10. Exhausted, Paul realizes that he cannot do this alone. So he collects money for the Jerusalem Church and makes his way to Jerusalem where he ends up causing a riot because of the perception that he says that Jews don't need to be circumcised. And he is carted off to Rome eventually.
