1:1-5 St. Paul was an apostle of Jesus Christ; he was expressly appointed by him, consequently by God the Father, who is one with him in respect of his Divine nature, and who appointed Christ as Mediator. Grace, includes God's good-will towards us, and his good work upon us; and peace, all that inward comfort, or outward prosperity, which is really needful for us. They come from God the Father, as the Fountain, through Jesus Christ. But observe, first grace, and then peace; there can be no true peace without grace. Christ gave himself for our sins, to make atonement for us: this the justice of God required, and to this he freely submitted. Here is to be observed the infinite greatness of the price bestowed, and then it will appear plainly, that the power of sin is so great, that it could by no means be put away except the Son of God be given for it. He that considers these things well, understands that sin is a thing the most horrible that can be expressed; which ought to move us, and make us afraid indeed. Especially mark well the words, for our sins. For here our weak nature starts back, and would first be made worthy by her own works. It would bring him that is whole, and not him that has need of a physician. Not only to redeem us from the wrath of God, and the curse of the law; but also to recover us from wicked practices and customs, to which we are naturally enslaved. But it is in vain for those who are not delivered from this present evil world by the sanctification of the Spirit, to expect that they are freed from its condemnation by the blood of Jesus.

2. all the brethren—I am not alone in my doctrine; all my colleagues in the Gospel work, travelling with me (Ac 19:29, Gaius and Aristarchus at Ephesus: Ac 20:4, Sopater, Secundus, Timotheus, Tychicus, Trophimus, some, or all of these), join with me. Not that these were joint authors with Paul of the Epistle: but joined him in the sentiments and salutations. The phrase, "all the brethren," accords with a date when he had many travelling companions, he and they having to bear jointly the collection to Jerusalem [Conybeare and Howson].

the churches—Pessinus and Ancyra were the principal cities; but doubtless there were many other churches in Galatia (Ac 18:23; 1Co 16:1). He does not attach any honorable title to the churches here, as elsewhere, being displeased at their Judaizing. See First Corinthians; First Thessalonians, &c. The first Epistle of Peter is addressed to Jewish Christians sojourning in Galatia (1Pe 1:1), among other places mentioned. It is interesting thus to find the apostle of the circumcision, as well as the apostle of the uncircumcision, once at issue (Ga 2:7-15), co-operating to build up the same churches.
