7 Which is not another; but there be some that trouble you, and would pervert the gospel of Christ.
11 But I certify you, brethren, that the gospel which was preached of me is not after man.
2 And I went up by revelation, and communicated unto them that gospel which I preach among the Gentiles, but privately to them which were of reputation , lest by any means I should run , or had run , in vain.
5 To whom we gave place by subjection, no, not for an hour; that the truth of the gospel might continue with you.
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;
14 But when I saw that they walked not uprightly according to the truth of the gospel, I said unto Peter before them all, If thou, being a Jew, livest after the manner of Gentiles, and not as do the Jews, why compellest thou the Gentiles to live as do the Jews ?
