1:18-25 The apostle begins to show that all mankind need the salvation of the gospel, because none could obtain the favour of God, or escape his wrath by their own works. For no man can plead that he has fulfilled all his obligations to God and to his neighbour; nor can any truly say that he has fully acted up to the light afforded him. The sinfulness of man is described as ungodliness against the laws of the first table, and unrighteousness against those of the second. The cause of that sinfulness is holding the truth in unrighteousness. All, more or less, do what they know to be wrong, and omit what they know to be right, so that the plea of ignorance cannot be allowed from any. Our Creator's invisible power and Godhead are so clearly shown in the works he has made, that even idolaters and wicked Gentiles are left without excuse. They foolishly followed idolatry; and rational creatures changed the worship of the glorious Creator, for that of brutes, reptiles, and senseless images. They wandered from God, till all traces of true religion must have been lost, had not the revelation of the gospel prevented it. For whatever may be pretended, as to the sufficiency of man's reason to discover Divine truth and moral obligation, or to govern the practice aright, facts cannot be denied. And these plainly show that men have dishonoured God by the most absurd idolatries and superstitions; and have degraded themselves by the vilest affections and most abominable deeds.

23. And changed—or "exchanged."

an image … like to corruptible man—The allusion here is doubtless to the Greek worship, and the apostle may have had in his mind those exquisite chisellings of the human form which lay so profusely beneath and around him as he stood on Mars' Hill; and "beheld their devotions." (See on [2180]Ac 17:29). But as if that had not been a deep enough degradation of the living God, there was found "a lower deep" still.

and to birds, and four-footed beasts, and to creeping things—referring now to the Egyptian and Oriental worship. In the face of these plain declarations of the descent of man's religious belief from loftier to ever lower and more debasing conceptions of the Supreme Being, there are expositors of this very Epistle (as Reiche and Jowett), who, believing neither in any fall from primeval innocence, nor in the noble traces of that innocence which lingered even after the fall and were only by degrees obliterated by wilful violence to the dictates of conscience, maintain that man's religious history has been all along a struggle to rise, from the lowest forms of nature worship, suited to the childhood of our race, into that which is more rational and spiritual.
