Paul identifies three "pillars" of the early church James (Jesus' brother), John, Peter kjv@Galatians:2:9. Modern Catholics identify only one: Peter. It is James here that delivers the group's verdict. John is either silent or absent. Paul is portrayed once again as serving the church under their authority (even when he has disagreement). I have no doubt that the Spirit was sought for this momentous decision but is not quoted. There is plenty of OT text regarding the inclusion of gentiles, but not mandatory circumcision of them. The decision is based then upon the consistency of the doctrine of saving grace.
