This epistle is not written, as most of St. Paul's are, to the Christians of a particular city, but to those of a whole country in Asia Minor, the metropolis of which was Ancyra. These readily embraced the gospel; but, after St. Paul had left them, certain men came among them, who (like those mentioned, (Ac 15:1).) taught that it was necessary to be circumcised, and to keep the Mosaic law. They affirmed, that all the other apostles taught thus; that St. Paul was inferior to them; and that even he sometimes practised and recommended the law, though at other times he opposed it.
The first part, therefore, of this epistle is spent in vindicating himself and his doctrine; proving,
That he had it immediately from Christ himself; and that he was not inferior to the other apostles.
That it was the very same which the other apostles preached. And,
That his practice was consistent with his doctrine.
The second contains proofs, drawn from the Old Testament, that the law and all its ceremonies were abolished by Christ.
The third contains practical inferences, closed with his usual benediction.
