1:3 {3} Concerning his {d} Son Jesus Christ our Lord, which was {e} made of the seed of David {f} according to the flesh;
(3) By declaring the sum of the doctrine of the Gospel, he stirs up the Romans to consider well the matter about which he is entreating them: so then he shows that Christ (who is the very substance and sum of the gospel) is the only Son of God the Father, who with regard to his humanity is born of the seed of David, but with regard to his divine and spiritual nature, by which he sanctified himself, is begotten of the Father from everlasting, as also manifestly appears by his mighty resurrection.
(d) This is a plain testimony of the person of Christ, that he is but one, and also a testimony of his two natures, and their properties.
(e) Who received flesh from the virgin who was David's daughter.
(f) As he is man: for this word flesh, by the figure of speech synecdoche, is taken for man.
1:3 Concerning his Son. The Son of God is the very center of the gospel, and the promises are all concerning him.
Born of the seed of David. The two natures combined in the Son, according to the flesh, are pointed out in this verse and Ro 1:4. As to his human body, he was a descendant of David (Lu 1:32,69), his mother being of David's lineage (Mt 1:16 Lu 3:23).
1:3 Who was of the seed of David according to the flesh - That is, with regard to his human nature. Both the natures of our Saviour are here mentioned; but the human is mentioned first, because the divine was not manifested in its full evidence till after his resurrection.
1:1-7 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.
