God's Sovereign Wisdom and Justice Vindicated
18For the wisdom of the Lord is great. He is mighty in power, and sees all things.19His eyes are upon those who fear him. He knows every act of man.20He has not commanded any man to be ungodly. He has not given any man license to sin.
Sirach 15:18–20 refutes the claim that God authors human sin by asserting that divine wisdom, power, and omniscience preclude ignorance, impotence, or circumstance as excuses. God has neither commanded ungodliness nor licensed sin, placing moral responsibility entirely upon human free will.
God's omniscience means no one can blame Him for sin—He sees all, commanded no one toward evil, and honors your freedom by holding you accountable for your choices.
Verse 18: "For the wisdom of the Lord is great. He is mighty in power, and sees all things."
The connecting particle "for" (Greek: ὅτι, hoti) is crucial: this verse is not a detached doxology but the logical conclusion of Ben Sira's preceding argument (vv. 11–17), in which he has rebutted the claim that God is the author of sin. The threefold assertion — great wisdom, mighty power, universal sight — forms a theological triad that deliberately counters three conceivable excuses for human sin. One cannot say God was ignorant of the situation (He sees all), that He lacked the power to prevent sin (He is mighty), or that He was outmaneuvered by circumstance (His wisdom is great). The Hebrew root behind "sees all things" (rō'eh) is the same used of God as the searching judge in the Psalms (Ps 33:13–15), reinforcing that divine vision is not passive observation but engaged moral governance. Ben Sira thus begins his conclusion by anchoring the moral order in the character of God Himself.
Verse 19: "His eyes are upon those who fear him. He knows every act of man."
The verse moves from the universal (He sees all things) to the particular (His eyes are upon those who fear him), then universalizes once more (every act of man). This is not a contradiction but a pastoral refinement: God's omniscience is personal. The phrase "those who fear him" (yir'av in Hebrew) echoes the foundational Wisdom motif — "fear of the Lord is the beginning of wisdom" (Sir 1:14; Prov 9:10) — reminding the reader that the one who truly understands God's nature will choose rightly. The second half, "He knows every act of man," employs the Hebrew yada' (to know), which in the Semitic idiom carries full relational and judicial weight, not merely cognitive awareness. God does not simply observe acts; He weighs, judges, and responds to them. This verse thus functions as both consolation (the righteous are not overlooked) and solemn warning (no deed escapes divine accounting).
Verse 20: "He has not commanded any man to be ungodly. He has not given any man license to sin."
This is the argumentative climax. Ben Sira employs a double negative construction — a literary device that in Hebrew poetry gives emphatic finality. The word "commanded" (tsivvah) is the same root used for divine commandments (mitzvot); to say God has not commanded ungodliness is to invoke the entire Mosaic framework and declare that sin exists in radical opposition to God's revealed will. "License" (Greek: ἄδειαν, adeian) literally means permission, freedom, or leave — a quasi-legal term — making the denial a juridical one: God has issued no warrant for sin, no dispensation, no amnesty in advance. The verse closes the entire passage by placing moral fault squarely where it belongs: in the free human will. The typological sense deepens this: just as God in Eden gave the command not to eat of the one tree (Gen 2:17) and thus defined the space of human moral freedom, the very existence of a divine prohibition presupposes — and honors — human capacity to choose otherwise.
The Spiritual Sense: Allegorically, the all-seeing eyes of God in v. 19 anticipate the gaze of Christ, who "knew what was in man" (John 2:25) and who, as Logos, is the very Wisdom of God enfleshed (1 Cor 1:24). Morally (the sensus moralis), the passage calls the reader to live coram Deo — before the face of God — recognizing that no sin is hidden and no virtue is unseen. Anagogically, God's refusal to license sin points toward the eschatological judgment where each act is rendered fully transparent before divine wisdom.
These three verses constitute one of the most theologically precise defenses of divine goodness in all of deuterocanonical Scripture, and Catholic Tradition has read them as a prophylactic against two persistent heresies.
Against Gnosticism and Manichaeism: The Church Fathers, particularly St. Augustine of Hippo, consistently had to refute the Manichaean claim that evil has a divine or co-eternal source. In De Libero Arbitrio (On Free Will), Augustine — himself a former Manichaean — argues precisely along the lines Ben Sira establishes: God's perfect goodness means He neither authored sin nor coerces the will toward it. Evil is a privatio boni (privation of good), never a positive creation of God. Sirach 15:20 is the scriptural bedrock of this position.
Against Predestinarianism: The Council of Trent, in its Decree on Justification (Session VI, 1547), explicitly teaches that God does not predestine anyone to sin. Canon 17 anathematizes anyone who claims God wills damnation without regard for human merits or demerits. Verse 20's declaration — "He has not commanded any man to be ungodly" — is a foundational scriptural warrant for this dogma.
The Catechism of the Catholic Church (§311) teaches that "God is in no way, directly or indirectly, the cause of moral evil." This is a direct doctrinal echo of Sirach 15:20. Furthermore, CCC §1730–1733 grounds human dignity itself in the freedom that makes moral responsibility possible — the same freedom Ben Sira presupposes by declaring that God licenses no sin.
St. John Chrysostom (Homilies on Genesis) uses this passage to insist that God's omniscience is never the cause of human choices, only their perfectly just witness. Divine foreknowledge, he argues, does not compel; it illumines.
In an age saturated with therapeutic and deterministic frameworks — genetic fatalism ("I was born this way"), social conditioning ("my environment made me"), or algorithmic influence ("the feed radicalizes people") — Sirach 15:18–20 cuts with surgical precision. The Catholic reading of this passage does not dismiss social or psychological factors, but it insists that they are never the final word. God, who sees every act and has authorized no one to sin, simultaneously honors the human person by holding them accountable. To deny personal moral responsibility is, paradoxically, to diminish one's own dignity as a rational, free creature made in God's image.
Practically, these verses invite an examination of conscience not rooted in guilt-as-neurosis but in sober clarity: God sees my acts, knows my interior life, and has given me no license for the rationalizations I construct. For Catholics preparing for the Sacrament of Reconciliation, this passage reframes confession not as a legal formality but as an honest response to a God whose wisdom is great, whose sight is total, and who — because He wills no one toward sin — also wills for every sinner to return.
