Second Mockery: Idols Imprisoned in Temples, Covered in Filth
17For like a vessel that a man uses is worth nothing when it is broken, even so it is with their gods. When they are set up in the temples, their eyes are full of dust through the feet of those who come in.18As the courts are secured on every side upon him who offends the king, as being committed to suffer death, even so the priests secure their temples with doors, with locks, and bars, lest they be carried off by robbers.19They light candles for them, yes, more than for themselves, even though they can’t see one.20They are like one of the beams of the temple. Men say their hearts are eaten out when things creeping out of the earth devour both them and their clothing. They don’t feel it21when their faces are blackened through the smoke that comes out of the temple.22Bats, swallows, and birds land on their bodies and heads. So do the cats.23By this you may know that they are no gods. Therefore don’t fear them.
Baruch 6:17–23 argues that Babylonian idols are not gods by cataloging their helplessness and degradation—broken like discarded vessels, requiring locks and guards, unable to see the worship directed at them, devoured by insects, blackened by smoke, and serving as perches for common animals. The passage warns exiled Jews not to fear these false gods, inverting the divine self-disclosure formula to show that impotence, not power, characterizes idolatry.
The god locked behind bars by priests to prevent theft is revealed as a prisoner, not a protector — and anything you must secure, fear, and constantly tend to is not worth your worship.
Commentary
Baruch 6:17 — The broken-vessel comparison. The opening simile is precise and devastating. A utilitarian vessel has worth only while it functions; once broken, it is discarded. The idol is likened not even to a broken vessel but to something equivalent in uselessness to one — the comparison implies the idol never had the functional dignity a vessel at least once possessed. The phrase "their eyes are full of dust" is clinically observed: the idol stands immobile while worshippers' sandaled feet raise clouds of temple dust that settle on the very face of the "god." Eyes are the traditional locus of divine perception in the ancient Near East (cf. the "Eye of Horus" or the all-seeing divine gaze in Mesopotamian iconography). That these eyes accumulate grit rather than perceive is a pointed inversion: the god is blind to the very act of worship directed at it.
Baruch 6:18 — The prison metaphor. The comparison to a man condemned to death, secured by the king's courts, is among the sharpest ironies in the passage. The priests do not open the temple doors to release divine power into the world; they bar them to prevent the idol from being stolen. The god requires the same security apparatus as a convicted criminal awaiting execution. Note the triple accumulation — "doors, with locks, and bars" — which rhetorically mirrors the triple helplessness of the god: it cannot see, cannot move, cannot protect itself. In Babylonian cult practice, the washing of the mouth (mīs pî) ceremony was intended to "animate" the idol; the Letter of Jeremiah implicitly mocks that entire theology. The god that must be animated by human ritual and then physically secured behind human locks is no god at all.
Baruch 6:19 — The absurdity of votive lamps. The priests lavish more candlelight on the idol than on themselves. The parenthetical — "even though they can't see one" — is the rhetorical equivalent of a dropped curtain. The idol cannot perceive the very honor paid to it. In the ancient world, lighting a lamp before a deity was an act of service, warmth, and recognition. Offering light to a being incapable of sight transforms piety into pantomime. The verse functions as an implicit contrast with the God of Israel, whose "eyes range throughout the earth" (2 Chr 16:9) and before whom even darkness is as light (Ps 139:12).
Baruch 6:20 — Vermin and rot. The idol's "heart" — the wooden core beneath the gilded exterior — is devoured by insects creeping from the earth. This is not mere poetic license; ancient composite statues (wood overlaid with gold or silver) were genuinely vulnerable to insect infestation. The author likely knew this from observation or report. The theological point, however, exceeds the practical: the god is consumed from within by the lowest creatures of creation, those that creep along the ground (cf. Gn 1:24–25, where creeping things are the most humble category of creature). What the idol cannot feel eating it alive, the God of Israel feels in the sufferings of his people (cf. Ex 3:7).
Baruch 6:21 — Smoke-blackened faces. The smoke of sacrifice and incense, which in Israelite worship rises upward as a pleasing aroma toward a living God (Lv 1:9), here merely darkens the idol's face. The passage inverts the entire logic of sacrifice: the offering reaches nothing. The face, again the locus of divine presence and communication in biblical theology (pānîm, "face/presence"), is not illuminated but obscured.
Baruch 6:22 — Birds, bats, and cats. The list escalates from the merely undignified (bats and swallows nesting on a statue) to the almost comic (cats). In Egyptian religion, the cat was itself a divine animal (the goddess Bastet). The Letter of Jeremiah may be making a quiet polemical point: even another culture's "gods" treat these idols as ordinary furniture. The verb "land on" is the language of casual, unhurried occupation — no creature fears the idol.
Baruch 6:23 — The pastoral conclusion. "By this you may know" echoes the Exodus formula of divine self-disclosure ("that you may know that I am the LORD," Ex 7:17; 14:4). Here it is inverted: by the evidence of impotence, one may know these are not God. The exhortation "do not fear them" is the direct pastoral application for exiled Jews tempted by the overwhelming cultural and political prestige of Babylonian religion. Fear belongs to God alone (Dt 6:13).
Catholic Commentary
Catholic tradition reads this passage within its canonical function as a sustained catechesis against idolatry — a category that the Church has never treated as historically obsolete. The Catechism of the Catholic Church teaches that idolatry consists in divinizing what is not God (CCC 2113), a vice that takes not only ancient but thoroughly modern forms: "power, pleasure, race, ancestors, the state, money" (CCC 2113). The Letter of Jeremiah's mockery is thus not antiquarian but perpetually applicable.
St. John Chrysostom, preaching on idol-worship in his own late-antique context, noted that the powerlessness of the idol is self-attesting: "He who needs men to protect him, how shall he protect you?" (Homily on First Corinthians 10). This is precisely the logic of Baruch 6:18. The prison-and-lock image prefigures this patristic argument: the idol is a dependent, not a provider.
St. Thomas Aquinas, following Augustine, identifies the root of idolatry as a disorder of latria — the worship owed to God alone being redirected to creatures (Summa Theologiae II-II, q. 94, a. 1). The very acts described here — lamplight, incense, veneration — are not wrong in themselves; it is their misdirection that constitutes the offense. Catholic worship of the living God is thereby implicitly vindicated by contrast: our candles illuminate One who truly sees; our incense rises toward One who truly receives it.
The Second Vatican Council's Gaudium et Spes (§19) locates modern atheism partly as a reaction to distorted religious images — false gods that degrade rather than elevate. The Letter of Jeremiah, in demolishing false gods with satire rather than polemic violence, models an apologetic mode: reason, observation, and mockery can serve true worship. Pope Benedict XVI, in Deus Caritas Est (§1), opened with the affirmation that God is love, precisely the quality these stone-and-wood constructs fatally lack.
For Today
The temptation this passage addresses is not primarily the temptation to worship a literal stone idol. For contemporary Catholics, the Letter of Jeremiah speaks to the cultural pressure to grant ultimacy — unconditional trust, final loyalty, existential hope — to things that, in the end, cannot see, hear, or save. Wealth secured behind the "locks and bars" of investment accounts, ideologies that promise human flourishing but cannot feel the suffering of the poor, technologies that light up our screens but leave hearts in darkness: these are the functional idols of our moment.
Practically, this passage invites an examination of conscience structured around the question the text itself implies: What do I fear? The closing command — "do not fear them" — assumes that fear is where idolatry begins. Where do I spend energy securing, protecting, and illuminating things that cannot reciprocate? The Catholic practice of Eucharistic adoration — kneeling before One who is truly present, who truly sees, who truly responds — is the lived antithesis of Baruch 6:17–23. Before the Blessed Sacrament, the candles are not absurd; they illuminate a Face that is not blackened by smoke but transfigured by glory.
