Paul insisted to the Galatians that any gospel other than his own was a deviation from the truth and amounted to departure from God Himself. This was an astonishing claim, which Paul knew he would have to defend. After confronting the charge that he was a man-pleaser, Paul began his defense of his gospel by identifying its source and showing how it was utterly alien to his former pharisaic understanding and convictions. So much so that what he now insisted on and proclaimed to all men, Jew and Gentile alike, he had formerly sought to eradicate.
