Listener,
I would say the key is in Paul's expression in Galatians regarding he and Barnabas being given the "right hand of sharing together" on this occasion.
Acts 15:25-26 — we have come to a unanimous accord and have favored choosing men to send to YOU together with our loved ones, Bar´na·bas and Paul, men that have delivered up their souls for the name of our Lord Jesus Christ.
This is when it happened, so the two passages correspond to the same event. But Paul says they were only told to "keep the poor in mind." Later, Paul instituted a "Don't Ask, Don't Tell" policy for the eating of things sacrificed to idols, and that even if they knew they would not sin in the eating except for not considering the consciences of others, which agrees with Jesus' "apostate" statement that it not what a man eats that defiles him. And that wasn't even in a "life or death" setting.
It is patently clear that Paul did not submit to the Pharisaical thinking, "no, not for an hour." He believed that the truth of the good news would be corrupted by doing so. That is what the argument in Acts was about, the former Pharisees and their followers were trying to "subvert [the] souls" of some by charging them to "keep the law of Moses." (Acts 15:5, 24)
The entire book of Galatians is an active letter against the idea of submission to the Acts 15 "decision" or any other man-made rules and regs. In Galatians 5:1-21, we find Paul arguing against "cirumcision" which he is obviously using euphemistically to refer to the whole law. I don't think many JWs look at it the way you have started to look at it, Listener. Paul wrote, "A little leaven ferments the whole lump."
What "leaven" was he referring to? (Matthew 16:5-12; Mark 8:14, 15; Luke 12:1-7)
It is an interesting side note that even after that Acts 15 meeting, Paul says the "men from James" compelled Peter to go separating himself. (Galatians 2:12) James said they didn't give any instructions, but Paul apparently still believed otherwise.
Respectfully,
