Romans 1:7

To all that are at Rome…called to be saints. That is, who not only are named saints, but who by such a call from God, are to be sanctified by his grace, and to become holy, or saints. (Witham)

the Romans are in this number, and a part of the nations to whom I have a commission, and for whom I have received the grace of apostleship. He adds this, to show his warrant for writing to them, he did it by virtue of his office; as also to humble them; for though they were Romans, and such as bore the greatest sway in the world, yet they were formerly pagans and idolaters. though such were some of you, to wit, heathen idolaters; yet now you are Christians, and the called of Jesus Christ: called outwardly by his word, and inwardly by his Spirit. By effectual calling you are become his disciples and followers.

IV. The apostolical benediction (v. 7): Grace to you and peace. This is one of the tokens in every epistle; and it hath not only the affection of a good wish, but the authority of a blessing. The priests under the law were to bless the people, and so are gospel ministers, in the name of the Lord. In this usual benediction observe, 1. The favours desired: Grace and peace. The Old-Testament salutation was, Peace be to you; but now grace is prefixed—grace, that is, the favour of God towards us or the work of God in us; both are previously requisite to true peace. All gospel blessings are included in these two: grace and peace. Peace, that is all good; peace with God, peace in your own consciences, peace with all that are about you; all these founded in grace. 2. The fountain of those favours, from God our Father, and the Lord Jesus Christ. All good comes, (1.) From God as a Father; he hath put himself into that relation to engage and encourage our desires and expectations; we are taught, when we come for grace and peace, to call him our Father. (2.) From the Lord Jesus Christ, as Mediator, and the great feoffee in trust for the conveying and securing of these benefits. We have them from his fulness, peace from the fulness of his merit, grace from the fulness of his Spirit.

Verses 1-7 The doctrine of which the apostle Paul wrote, set forth the fulfilment of the promises by the prophets. It spoke of the Son of God, even Jesus the Saviour, the promised Messiah, who came from David as to his human nature, but was also declared to be the Son of God, by the Divine power which raised him from the dead. The Christian profession does not consist in a notional knowledge or a bare assent, much less in perverse disputings, but in obedience. And all those, and those only, are brought to obedience of the faith, who are effectually called of Jesus Christ. Here is, 1. The privilege of Christians; they are beloved of God, and are members of that body which is beloved. 2. The duty of Christians; to be holy, hereunto are they called, called to be saints. These the apostle saluted, by wishing them grace to sanctify their souls, and peace to comfort their hearts, as springing from the free mercy of God, the reconciled Father of all believers, and coming to them through the Lord Jesus Christ.
