It must be remembered that what Paul in Gal. ii. 1-10 desires most of all to prevent is the impression that he is appealing to the Jerusalem apostles as to a higher instance. He is not basing the authority of his preaching upon any authorization that the apostles gave him; he is not saying that he has a right to be heard because those who were the pillars of the Church endorsed his message. Such a representation of the conference would have cast despite upon all the work which he had done before, and would have made it necessary for him in the future to prove constantly against all Judaizers and other opponents his agreement with the Jerusalem authorities. The profound consciousness which he had of his apostolic authority did not permit any such course of action; and such restrictions would have hindered his work wherever he went. It was absolutely essential in the economy of God that the leader of the Gentile work should have independent authority and should not be obliged to appeal again and again to authorities who were far away, at Jerusalem. Hence what Paul desires to make clear above all in Gal. ii.
1-10 is that though he appealed to the Jerusalem authorities it was not necessary for his own sake for him to appeal to them.They were great, but their greatness had absolutely nothing to do with his authority; for they added nothing to him. It was therefore not the real greatness of the original apostles which caused him to appeal to them (for he needed no authorization from any man no matter how great), but only the greatness which was attributed to them by the Judaizers. They really were great, but it was only the false use which had been made of their greatness by the Judaizers which caused him to lay his gospel before them. The Judaizers were to be refuted from the lips of the very authorities to whom they appealed. (The Origin of Paul’s Religion, 121-22)
