THIS epistle of Paul is directed not to the church or churches of a single city, as some others are, but of a country or province, for so Galatia was. It is very probable that these Galatians were first converted to the Christian faith by his ministry; or, if he was not the instrument of planting, yet at least he had been employed in watering these churches, as is evident from this epistle itself, and also from Acts xviii. 23, where we find him going over all the country of Galatia and Phrygia in order, strengthening all the disciples. While he was with them, they had expressed the greatest esteem and affection both for his person and ministry; but he had not been long absent from them before some judaizing teachers got in among them, by whose arts and insinuations they were soon drawn into a meaner opinion both of the one and of the other. That which these false teachers chiefly aimed at was to draw them off from the truth as it is in Jesus, particularly in the great doctrine of justification, which they grossly perverted, by asserting the necessity of joining the observance of the law of Moses with faith in Christ in order to it: and, the better to accomplish this their design, they did all they could to lessen the character and reputation of the apostle, and to raise up their own on the ruins of his, representing him as one who, if he was to be owned as an apostle, yet was much inferior to others, and particularly who deserved not such a regard as Peter, James, and John, whose followers, it is likely, they pretended to be: and in both these attempts they had but too great success. This was the occasion of his writing this epistle, wherein he expresses his great concern that they had suffered themselves to be so soon turned aside from the faith of the gospel, vindicates his own character and authority as an apostle against the aspersions of his enemies, showing that his mission and doctrine were both divine, and that he was not, upon any account, behind the very chief of the apostles, 2 Cor. xi. 5. He then sets himself to assert and maintain the great gospel doctrine of justification by faith without the works of the law, and to obviate some difficulties that might be apt to arise in their minds concerning it: and, having established this important doctrine, he exhorts them to stand fast in the liberty wherewith Christ had made them free, cautions them against the abuse of this liberty, gives them several very needful counsels and directions and then concludes the epistle by giving them a just description of those false teachers by whom they had been ensnared, and, on the contrary, of his own temper and behaviour. In all this his great scope and design were to recover those who had been perverted, to settle those who might be wavering, and to confirm such among them as had kept their integrity.
