Commentaries:
All James does is add his two cents, as it were, confirming that he could see in the Scriptures that what had happened to Peter in his first meeting with the Gentiles, with Cornelius, God had previously shown that He was going to do it. James then gives a practical application of the decision that had been made by Peter, and the rest confirm that this indeed is what was to be done.
