And declared--literally, "marked off," "defined," "determined," that is, "shown," or "proved." to be the Son of God--Observe how studiously the language changes here. He "was MADE [says the apostle] of the seed of David, according to the flesh" (Rom 1:3); but He was not made, He was only "declared [or proved] to BE the Son of God." So Joh 1:1, Joh 1:14, "In the beginning WAS the Word . . . and the Word was MADE flesh"; and Isa 9:6, "Unto us a Child is BORN, unto us a Son is GIVEN."

This is here styled the "spirit," as an impalpable and immaterial nature (Joh 4:24), and "the spirit of holiness," probably in absolute contrast with that "likeness, of sinful flesh" which He…

In this chapter we may observe, I. The preface and introduction to the whole epistle, to Rom 1:16. II. A description of the deplorable condition of the Gentile world, which begins the proof of the doctrine of justification by faith, here laid down at Rom 1:17. The first is according to the then usual formality of a letter, but intermixed with very excellent and savoury expressions.

1:4 he was shown to be: Although Jesus eternally existed as the Son of God (1:3), his resurrection demonstrated him to be God’s Son, revealing him in all his power and glory.
