Narkissos,
Or we can say that Paul was highly respectful of them and overly cautious. After all there were other apostles involved as well as the brother of Jesus. Even so he would write: Gal 2:4 And that because of false brethren unawares brought in, who came in privily to spy out our liberty which we have in Christ Jesus, that they might bring us into bondage: 5 To whom we gave place by subjection, no, not for an hour; that the truth of the gospel might continue with you. 6 But of these who seemed to be somewhat, (whatsoever they were, it maketh no matter to me: God accepteth no man’s person:) for they who seemed to be somewhat in conference added nothing to me: 7 But contrariwise, when they saw that the gospel of the uncircumcision was committed unto me, as the gospel of the circumcision was unto Peter; 8 (For he that wrought effectually in Peter to the apostleship of the circumcision, the same was mighty in me toward the Gentiles:) 9 And when James, Cephas, and John, who seemed to be pillars, perceived the grace that was given unto me, they gave to me and Barnabas the right hands of fellowship; that we should go unto the heathen, and they unto the circumcision. Can you imagine saying that such men like James, Cephas and John, "seemed to be pillars" or "But of these who seemed to be somewhat, (whatsoever they were, it maketh no matter to me: God accepteth no man’s person:) for they who seemed to be somewhat in conference added nothing to me:" But Paul was still pretty new and dependent on others as he was on Antioch. Later we would see the changes Paul was noted for. I know many here can relate to this growth and have experienced something like this themselves.
