ISB ~ Galatians 2 v2

I laid before them:Paul received his gospel directly from Christ (1:12), yet he submitted it for approval to the senior apostles in Jerusalem (Acts 15:2). This was to confirm that his message was in line with the doctrine of the Twelve and to remove suspicions that his missionary efforts were at odds with the authority of the Church’s recognized leaders. In the end, the pillar apostles “added nothing” to his message (Gal 2:6) and openly affirmed his ministry by giving him the “right hand of fellowship” (2:9).
