Gal 1v11,12: "But I make known to you, brethren, that the gospel which was preached by me is not according to man. For I neither received it from man, nor was I taught it, but it came through the revelation of Jesus Christ."
Gal 2v1-10: "Then after fourteen years I went up again to Jerusalem with Barnabas, and also took Titus with me. And I went up by revelation, and communicated to them that gospel which I preach among the Gentiles, but privately to those who were of reputation, lest by any means I might run, or had run, in vain. Yet not even Titus who was with me, being a Greek, was compelled to be circumcised. And this occurred because of false brethren secretly brought in (who came in by stealth to spy out our liberty which we have in Christ Jesus, that they might bring us into bondage), to whom we did not yield submission even for an hour, that the truth of the gospel might continue with you. But from those who seemed to be something — whatever they were, it makes no difference to me; God shows personal favoritism to no man — for those who seemed to be something added nothing to me. But on the contrary, when they saw that the gospel for the uncircumcised had been committed to me, as the gospel for the circumcised was to Peter (for He who worked effectively in Peter for the apostleship to the circumcised also worked effectively in me toward the Gentiles), and when James, Cephas, and John, who seemed to be pillars, perceived the grace that had been given to me, they gave me and Barnabas the right hand of fellowship, that we should go to the Gentiles and they to the circumcised. They desired only that we should remember the poor, the very thing which I also was eager to do."
1Cor 1v23,24: "but we preach Christ crucified, to the Jews a stumbling block and to the Greeks foolishness, but to those who are called, both Jews and Greeks, Christ the power of God and the wisdom of God."
Rom 1v16: "For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to every one that believeth; to the Jew first, and also to the Greek."
