Those 4 rules have nothing to do with Christianity. They were synagogue rules that proselytes of the gate (gentile God fearers) had to follow in order to attend synagogues to learn the gospel. James was just telling them to keep doing what they were aready doing and not worry about the pharisees who were telling them that they had to get circumcised and keep the law in order to be saved, ie, become a proselyte of righteousness.
That’s an interesting interpretation. Did you come up with it on your own or did you use Ai to help you? Either way it misses the actual context of why James gives those four prohibitions in Acts 15.
The issue at hand wasn’t synagogue attendance—it was salvation apart from the law. The council gathered to settle whether Gentiles needed circumcision and Mosaic law to be saved (Acts 15:1, 5, 11). When James lists those four restrictions, he isn’t re-imposing ceremonial law or synagogue protocol; he’s identifying the things that would most offend Jewish believers and disrupt fellowship in the mixed Gentile-Jewish churches now forming throughout the empire.
Notice verse 28–29:
“It seemed good to the Holy Ghost, and to us, to lay upon you no greater burden than these necessary things...”
These weren’t “synagogue rules” but moral and relational safeguards to preserve unity between Jewish and Gentile believers—issues deeply tied to idolatry and pagan worship. Every one of the four items had direct connections to temple idolatry and sexual impurity. Abstaining from them kept Gentile converts from dragging their old pagan practices into Christian fellowship.
Verse 21 (“For Moses of old time hath in every city…”) simply explains why Gentiles would already understand these sensitivities—they’d heard the Law of Moses read in synagogues every Sabbath. It’s not saying these are synagogue requirements, but that Gentiles would recognize the offense those behaviors caused among Jewish believers.
So the decree is not about earning salvation or qualifying for synagogue instruction—it’s about living out salvation in a way that honors Christ and maintains peace within the one body of believers (Romans 14:13–19; 1 Cor 8:9–13).
Grace and peace.
