And changed the glory of the uncorruptible God into an image made like to corruptible man, and to birds, and fourfooted beasts, and creeping things.
Paul describes the essence of idolatry: kai ēllaxan tēn doxan tou aphthartou theou en homoiōmati eikonos phthartou anthrōpou kai peteinōn kai tetrapodōn kai herpetōn (καὶ ἤλλαξαν τὴν δόξαν τοῦ ἀφθάρτου θεοῦ ἐν ὁμοιώματι εἰκόνος φθαρτοῦ ἀνθρώπου καὶ πετεινῶν καὶ τετραπόδων καὶ ἑρπετῶν, 'and exchanged the glory of the incorruptible God for an image of corruptible man, and birds, and four-footed beasts, and creeping things').
Ēllaxan (ἤλλαξαν, exchanged) is a commercial term—humanity traded the infinitely valuable for the worthless. Tēn doxan tou aphthartou theou (τὴν δόξαν τοῦ ἀφθάρτου θεοῦ, the glory of the incorruptible God) refers to God's eternal, unchanging, radiant majesty. They exchanged this for homoiōmati eikonos phthartou (ὁμοίωμα εἰκόνος φθαρτοῦ, an image/likeness of corruptible things). The descending order—man, birds, quadrupeds, reptiles—echoes Genesis 1 in reverse, a de-creation. Humanity, made in God's image (Genesis 1:27), now worships images of creatures. This is cosmic insanity—the creature worshiping the creature rather than the Creator. It violates the second commandment (Exodus 20:4-6) and Deuteronomy 4:15-19.
Historical Context
Ancient idolatry was pervasive. Egyptians worshiped animal-headed gods (Anubis, Horus). Greeks fashioned anthropomorphic deities (Zeus, Aphrodite). Romans adopted these, adding emperor worship. Jewish readers would recall Israel's golden calf (Exodus 32), making an image 'like a calf that eats grass' (Psalm 106:19-20). Temples with statues, shrines, and household idols saturated the Roman world. Paul's audience in Rome would have walked past countless such images daily. Modern idolatry is subtler—self, money, pleasure, power—but equally destructive.
Questions for Reflection
What are you tempted to 'exchange' (ἀλλάσσω) the glory of God for—what created things rival God's supreme worth in your life?
How does idolatry involve not just addition (adding false gods) but exchange (replacing the true God)?
What modern idols do Christians rationalize or disguise that are spiritually equivalent to ancient statues?
