The Divine Self-Revelation: The Thirteen Attributes of God
5Yahweh descended in the cloud, and stood with him there, and proclaimed Yahweh’s name.6Yahweh passed by before him, and proclaimed, “Yahweh! Yahweh, a merciful and gracious God, slow to anger, and abundant in loving kindness and truth,7keeping loving kindness for thousands, forgiving iniquity and disobedience and sin; and who will by no means clear the guilty, visiting the iniquity of the fathers on the children, and on the children’s children, on the third and on the fourth generation.”
God's first word about Himself is not judgment but womb-love—and He swears this to us twice, as though interrupting Himself with compassion.
In one of the most theologically charged moments in the entire Hebrew Bible, God descends in cloud and personally proclaims His own Name and character to Moses on Sinai. The thirteen divine attributes revealed here — anchored by mercy, grace, patience, and covenantal faithfulness, yet balanced by uncompromising justice — constitute what Jewish and Christian tradition alike regard as the definitive divine self-disclosure of the Old Testament. This passage is not merely a description of God; it is God's own sworn testimony about Himself, the foundation upon which all subsequent revelation of the divine nature rests.
Verse 5 — The Descent and the Proclamation of the Name
The setting is momentous: Moses has shattered the first tablets after the golden calf catastrophe (Ex. 32), and God has consented, through Moses' extraordinary intercession, to renew the covenant. Moses had boldly asked to see God's glory (Ex. 33:18); God's response is not a vision of His face — which no mortal can survive — but something more intimate still: the proclamation of His Name. The cloud (anān) is the same luminous obscurity that led Israel through the wilderness — a theophanic veil that simultaneously conceals divine majesty and mediates divine presence. God "stood with him there," a phrase that echoes the relational closeness Moses enjoyed uniquely among Israel's leaders (Num. 12:8). The proclamation of the Name (Yahweh) is itself an act of power and self-gift: in the ancient world, to know and speak a name was to enter into relationship with its bearer. God does not merely describe Himself; He names Himself into relationship.
Verse 6 — The Thirteen Attributes: Mercy at the Center
As God "passes before" Moses — recalling the earlier promise that His goodness would pass before Moses while his face remained hidden (Ex. 33:19–23) — He utters a confession that rabbinic tradition would count as thirteen distinct divine attributes (Shelosh Esreh Middot), a formula cited, echoed, or alluded to more than a dozen times across the Old Testament (Num. 14:18; Ps. 86:15; Joel 2:13; Jon. 4:2; Neh. 9:17). The sequence is deliberate and cumulative:
Catholic tradition identifies this passage as the Old Testament's most concentrated revelation of the divine nature, and reads it as a direct preparation for the Johannine declaration that "God is love" (1 Jn. 4:8).
The Church Fathers were deeply attentive to verse 6. Origen (Homilies on Exodus 13) saw the double proclamation of "Yahweh! Yahweh" as pointing toward the two comings of Christ — the first in humility and mercy, the second in judgment. Gregory of Nyssa (Life of Moses II.220–255) read Moses' progressive ascent into the divine darkness as a paradigm of the soul's mystical union with God, with this proclamation as the summit: not an intellectual apprehension of God but a reception of His self-gift in love.
The Catechism draws directly on the Sinai theophany when presenting the divine attributes. CCC 210–211 cites Exodus 34:6 explicitly: "'The Lord, the Lord, a God merciful and gracious' ... God's very being is Truth and Love." CCC 214 develops emet (truth/faithfulness) as the foundation of Israel's trust in God. Pope St. John Paul II's encyclical Dives in Misericordia (1980, §4) treats this passage as the inaugural definition of divine mercy in Scripture, noting that ḥesed and raḥamim together constitute a profile of God's love that is both spousal and maternal.
Crucially, Catholic theology holds that the tension between mercy and justice in verse 7 is not a theological problem to be explained away but a mystery to be inhabited — one whose resolution the Church Fathers uniformly located in the Paschal Mystery. St. Anselm's satisfaction theology and St. Thomas Aquinas (Summa Theologiae I, q.21, aa. 3–4) both affirm that in the Cross, God's justice is not overridden by mercy but fulfilled through it: the punishment that justice requires is absorbed by Love Himself, so that sinners may be forgiven without guilt being "cleared" cheaply.
The "thirteen attributes" of Exodus 34:6–7 are not abstract theology — they are a portrait of the God Catholics address every time they pray. Several concrete applications deserve attention.
First, for those who struggle to pray the Psalms of divine wrath or who feel God is remote and punitive, this passage is the corrective: God's first word about Himself is raḥûm — womb-love. Mercy is not God's afterthought; it is His self-introduction.
Second, the phrase "slow to anger" (erek appayim) invites an examination of conscience not only about how we imagine God but about how we relate to others. The Sacrament of Reconciliation is the liturgical enactment of this passage: the penitent stands before the God who "will by no means clear the guilty" and simultaneously before the God who is "abundant in loving kindness." Both truths must be held — cheap grace that ignores sin is a lie, but scrupulosity that doubts God's mercy is equally a distortion.
Third, the intergenerational dimension of verse 7 challenges families and communities to examine how patterns of sin — addiction, abuse, dishonesty, broken relationships — are transmitted across generations, and to embrace the Church's sacramental life as precisely the means by which those chains are broken.
Verse 7 — Justice as the Guardian of Love
The passage does not end in pure consolation. God declares that He keeps ḥesed "for thousands" — an asymmetry the text deliberately sets against the "third and fourth generation" of punishment. Mercy is exponentially larger than judgment. Yet the formula insists: God "will by no means clear the guilty" (naqqēh lō' yenaqqeh, an emphatic double negative). This is not a contradiction of mercy but its moral precondition. Love that ignores evil is not love — it is indifference. The "visiting of iniquity" on subsequent generations is not mechanical hereditary punishment (see Ezek. 18:1–4, which expressly corrects that misreading) but the observable moral ecology of sin: the destructive consequences of a parent's choices cascade through family and community. The passage holds mercy and justice in a tension that the New Testament will not dissolve but will resolve — in the cross.
