Judaizing teachers are mentioned in many of the Epistles: they had made inroads among the Corinthians (2 Cor. 11:22), the Philippians (Phil. 3:2), the Colossians (Col. 2:18), but nowhere with as much success as among the Galatian assemblies. The tendency towards natural religion has been the bane of Christianity. They were those of whom Paul wrote, "desiring to be teachers of the law; understanding neither what they say, nor whereof they affirm" (1 Tim. 1:7). They were of Jewish ethnicity, but had come under the umbrella of Christianity. They found some benefit to being among Christians. Their primary motive was to gain a following after themselves, and perhaps to profit financially. They claimed to be closely connected to the Jewish leaders in Jerusalem, but they could not prove their genealogy as Paul could (Phil. 3). Paul was raised up as a suited vessel to deal with the Judaizers, because he himself had been one!
