Romans 1:4 Meaning and Commentary

Romans 1:4

And declared to be the Son of God
Not made as he is said to be before, when his incarnation is spoken of; nor did he begin to be the Son of God, when he was made of the seed of David, but he, the Son of God, who existed as such, from everlasting, was manifested in the flesh, or human nature: and this his divine sonship, and proper deity, are declared and made evident,

with,
or "by"

[his] power;
which has appeared in the creation of all things out of nothing; in upholding all things in their beings; in the government of the world, and works of Providence; in the miracles he wrought; in his performing the great work of redemption; in the success of his Gospel, to the conversion of sinners; and in the preservation of his churches and people: here it seems chiefly to regard the power of Christ in raising the dead, since it follows, and which is to be connected with this clause,

by the resurrection from the dead;
and designs either the resurrection of others, as of Lazarus, and some other persons, in his lifetime, and of some at his resurrection, and of all at the last day: or the resurrection of his own body, which dying he had power to raise up again, and did; and which declared him to be, or clearly made it appear that he was the Son of God, a divine person, truly and properly God: and this was done

according to the Spirit of holiness;
which may be understood of the Holy Spirit, the third person in the Trinity, who is holy in himself, and the author of holiness in the saints; and who is the declarer of Christ's sonship, partly by bearing a testimony to it in the word, and in the hearts of believers, and chiefly by being concerned in the resurrection of the body of Christ from the dead; or else by the Spirit of holiness may be meant the divine nature of Christ, which, as it is holy, so by it Christ offered himself to God, and by it was quickened, or made alive, when he had been put to death in the flesh; and which must be a clear and strong proof of his being truly the Son of God.
