Romans 1:23

“And changed the glory of the incorruptible God, etc..] God is incorruptible and immortal in his nature, and so is opposed to all corruptible creatures and things: he has a glory which is essential to him, and a manifestative one in the creatures, and which is relative, and of right belongs to him: his absolute essential glory cannot be changed, cannot be taken away from him, nor given to another; but his relative glory may be said to be changed, when another is worshipped in his stead, and called by his name. So Philo the Jew f7 speaks of “some, who, leaving the true God, make to themselves false ones, and impose the name of the eternal and incorruptible upon created and corruptible beings.”…”

“And changed--or "exchanged." the glory of the uncorruptible God into--or "for" 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 Act 17:29).

They forsook him of whom they had knowledge Romans 1:21, and offered the homage which was due to him, to idols. The glory - The majesty, the honor, etc. This word stands opposed here to the “degrading” nature of their worship. Instead of adoring a Being clothed with majesty and honor, they bowed down to reptiles, etc. They exchanged a glorious object of worship for what was degrading and humiliating. The…”

“And changed - With the utmost folly. Here are three degrees of ungodliness and of punishment: the first is described, Rom 1:21-24; the second, Rom 1:25-27; the third, in Rom 1:28, and following verses. The punishment in each case is expressed by God gave them up. If a man will not worship God as God, he is so left to himself that he throws away his very manhood. Reptiles - Or creeping things; as beetles, and various kinds of serpents. Romans 1:24”
