The Significance Of Galatians 2:9

I've often discussed how unlikely it is that Galatians 2:9 would have been written if the earliest Christians had believed in a papacy. Not only is Galatians a good place to go when addressing the doctrine of justification, but it's also a good place to go when the papacy is being discussed. But notice that Galatians 2:9 is also significant in the context of the historicity of the gospels and Acts. Those documents portray Peter, James, and John as the most prominent members of the Twelve (for non-papal reasons), frequently putting Peter and John together, and Galatians 2:9 has Peter and John together as reputed pillars of the church (James the son of Zebedee being dead by then). And the prominence of James the brother of Jesus in Galatians 2:9 is what we'd expect from Acts. So is the placing of Paul and Barnabas together. There's other relevant material in Galatians as well, but 2:9 is a good passage to remember as one that concisely illustrates so much.
