This epistle was written from Corinth, as the subscription of it testifies; and which may be confirmed from the apostle's commendation of Phoebe, by whom he sent it, who was of Cenchrea, a place near Corinth; by his calling Erastus, the chamberlain of the city, who abode at Corinth, 2Tim. 4:20, and Gaius his host, who was a Corinthian, Rom. 16:23 1Co 1:14, This epistle was sent to the Roman saints, both Jews, and Gentiles, inhabiting the city of Rome; of which city and church; by whom the Gospel was first preached at Rome, and who were the means of forming the church there. Certain it is, that the Apostle Paul had not been at Rome when he wrote this epistle, at least it seems very probable he had not, by several expressions in Ro 1:10-15; and yet here was a church to which he writes, and had been a considerable time; for their faith was spoken of throughout the world, Rom. 1:8; and when the apostle was on the road to this city, the brethren in it met him, Ac 28:15 . The chief design of this epistle is to set in a clear light the doctrine of justification: showing against the Gentiles, that it is not by the light of nature, and works done in obedience to that, and against the Jews, that it was not by the law of Moses, and the deeds of that; which he clearly evinces, by observing the sinful and wretched estate both of Jews and Gentiles: but that it is by the righteousness of Christ imputed through the grace of God, and received by faith; the effects of which are peace and joy in the soul, and holiness in the life and conversation: he gives an account of the justified ones, as that they are not without sin, which he illustrates by his own experience and case; and yet are possessed of various privileges, as freedom from condemnation, the blessing of adoption, and a right to the heavenly inheritance; he treats in it concerning predestination, the calling of the Gentiles, and the rejection of the Jews; and exhorts to the various duties incumbent on the saints, with respect to one another, and to the world, to duties of a moral and civil nature, and the use of things indifferent; and closes it with the salutations of divers persons.
