Superscription: The Oracle Against Babylon
1The burden of Babylon, which Isaiah the son of Amoz saw.
Isaiah 13:1 presents the superscription introducing Isaiah's oracle against Babylon, using the Hebrew term massa (burden) to denote a divinely-commissioned prophetic judgment. The verse establishes that Isaiah the prophet received a vision of Babylon's divinely-ordained fate, marking the beginning of the book's collection of oracles against various nations.
A single Hebrew word—massa, "burden"—announces that the mightiest empire on earth stands judged by God, and no power since has proven that verdict wrong.
Narrative and structural function: This superscription inaugurates what scholars call the "Book of Oracles Against the Nations" (Isaiah 13–23), a collection of massaoth against Babylon, Assyria, Philistia, Moab, Damascus, Egypt, and others. By beginning this section with Babylon — historically the latest and most theologically resonant of Israel's oppressors — Isaiah (or the final form of the book) places the most paradigmatic enemy first, inviting the reader to interpret all subsequent oracles through the lens of God's sovereignty over every empire and every idol.
Catholic tradition reads Isaiah 13:1 through at least three overlapping theological lenses.
1. Divine sovereignty over history. The massa formula is itself a confession of faith: history is not the random movement of imperial forces but the arena of divine justice. The Catechism teaches that God "is the sovereign master of his plan" and that he "permits" evil and human rebellion precisely to bring about a greater good (CCC 312). Isaiah's oracle against Babylon is an instance of this providential pedagogy — empires rise in their pride and fall under divine judgment.
2. The theology of prophetic inspiration. The phrase "which Isaiah… saw" invites reflection on the nature of Sacred Scripture itself. Vatican II's Dei Verbum §11 teaches that the sacred authors wrote "with the assistance of the Holy Spirit" while remaining "true authors" using "their own faculties and powers." Isaiah's vision of Babylon exemplifies this: genuinely human perception, genuinely divine disclosure. St. Jerome, who translated this very verse, wrote in his Commentary on Isaiah that the prophet's words are "not the words of a man speaking his own mind, but of the Spirit of God speaking through a man."
3. Babylon as theological type. The Church Fathers — notably Tertullian, Origen, and St. Augustine in The City of God — consistently interpret Babylon as a type (figura) of every earthly city that organizes itself around power, wealth, and the rejection of God. Augustine's two-city framework (City of God vs. City of Man) finds its Old Testament root precisely in the Babylon/Jerusalem antithesis that Isaiah 13–14 dramatizes so powerfully. The Catechism itself (CCC 1818–1821) echoes this in its treatment of hope: the Christian lives as a stranger to every "Babylon," awaiting the city whose architect and builder is God (Heb 11:10).
For contemporary Catholics, this single-verse superscription offers a bracing counter-cultural word. We live inside multiple "Babylons" — economic systems, media empires, political ideologies, and consumer cultures — each of which implicitly claims ultimate allegiance and promises fulfillment. Isaiah's massa reminds us that no earthly power is exempt from divine judgment, no matter how permanent or inevitable it appears. The oracle was addressed to the mightiest empire of its age; no empire since has proven it wrong.
Practically, this verse calls Catholics to the discipline of prophetic seeing — learning to perceive reality as Isaiah did, through the lens of God's sovereign justice rather than through the lens of cultural inevitability. This is not pessimism but clarity. It invites an examination of conscience: In what ways have I made peace with a "Babylon" — a system, habit, or ideology — that God has already judged? The spiritual life requires the courage to name the burden and carry the oracle, even when unwelcome.
Commentary
Isaiah 13:1 — "The burden of Babylon, which Isaiah the son of Amoz saw."
Every word in this terse superscription carries exegetical weight.
"The burden" (massa): The Hebrew word massa derives from the root nasa', meaning "to lift up" or "to carry." In prophetic literature it functions as a technical term for a divine oracle, often — though not exclusively — one of judgment. The weight implied is twofold: it is a heavy word that the prophet must bear and deliver, and it is a weighty fate that the nation addressed must bear in history. Jerome in his Vulgate renders it onus ("burden," "load"), preserving the sense of something oppressive and laden with gravity. The Septuagint uses hórama ("vision"), shifting emphasis to the visionary mode of reception, but the onus tradition better captures the moral and eschatological gravity Isaiah intends. Catholic commentators from Origen through St. Robert Bellarmine have noted that the massa formula signals not mere political prediction but a theological verdict — God's just response to human arrogance.
"Of Babylon": That Isaiah, a prophet of the eighth century B.C., delivers an oracle against Babylon is historically significant and theologically charged. In Isaiah's own day, the dominant Mesopotamian threat was Assyria, not Babylon; Babylon would not become the world-hegemon and the destroyer of Jerusalem until the late seventh and early sixth centuries B.C. This has led some modern critics to question the unity of Isaiah 13–14 with the earlier chapters. Catholic tradition, following the Church's reading of prophetic inspiration, holds that Isaiah genuinely foresaw Babylon's rise and fall as part of the divine economy of history (cf. CCC 702). More importantly, "Babylon" in the prophetic and later apocalyptic imagination quickly becomes a theological symbol — the city of confusion (cf. Gen 11), the seat of idolatry, the empire that exiles the people of God. This symbolic weight extends canonically into the New Testament Book of Revelation, where "Babylon" names every power that sets itself against the Kingdom of God.
"Which Isaiah the son of Amoz saw": The verb "saw" (hazah, sometimes ra'ah) is the standard term for prophetic vision — the prophet does not merely hear a message but perceives a reality disclosed to him by God. The naming of "Isaiah son of Amoz" (identical to the book's opening superscription in 1:1) serves an authenticating function: this oracle belongs to the authoritative prophetic corpus, not to anonymous speculation. It also reminds the reader that every judgment oracle ultimately passes through the consciousness of a human being summoned, formed, and commissioned by God — a point St. Thomas Aquinas stresses in his theology of prophecy ( II-II, q. 171–174), where prophetic knowledge is a , a light supernaturally infused without bypassing the prophet's human faculties.
