The Just King and the Call to Exalt Him
4The King’s strength also loves justice. You establish equity. You execute justice and righteousness in Jacob.5Exalt Yahweh our God. Worship at his footstool. He is Holy!
Psalms 99:4–5 declares that God's power and strength are inseparable from His love of justice, and calls His people to exalt and lift Him up in worship. The passage asserts that divine omnipotence is not morally neutral but constitutively oriented toward justice, and that the congregation's exaltation raises their minds and hearts to recognize God's true nature.
God's power doesn't merely tolerate justice—it actively loves it, meaning every act of His kingship flows from His deepest nature, not from external constraint.
Catholic tradition brings several distinct illuminations to these verses.
On the unity of power and justice in God: The Catechism of the Catholic Church teaches that God's omnipotence "is in no way arbitrary" (CCC 271–272) and that all God's attributes — including power — are identical with His essence. Thomas Aquinas, building on Augustine, insists that God's justice and mercy are not in tension but flow from the same simple divine nature (Summa Theologiae I, q. 21). Verse 4's claim that strength loves justice is thus, for Catholic theology, not a poetic decoration but a precise metaphysical statement: God cannot exercise power unjustly because justice is what He is.
On kingship and Christ: The encyclical Quas Primas (Pius XI, 1925), which instituted the Solemnity of Christ the King, draws on precisely this Psalmic tradition. Christ's kingship, the document teaches, is "spiritual" yet exercises dominion over human conscience, society, and history — a kingdom whose law is love and whose justice redeems rather than merely punishes.
On liturgical exaltation: The Fathers, especially St. John Chrysostom, understood that the command to exalt God is fulfilled preeminently in the Eucharist. Praising God is not optional piety but a constitutive act of creaturely righteousness — to withhold praise is itself an injustice (cf. CCC 2096–2097). Vatican II's Sacrosanctum Concilium (§83) sees the Liturgy of the Hours as the continuation of this Psalmic mandate, the Church perpetually "exalting" God through the voice of Christ her Head.
For contemporary Catholics, verse 4 is a direct challenge to the temptation to separate power from accountability. In an age when authority — ecclesiastical, political, or personal — is frequently exercised self-servingly, the psalm insists that legitimate power loves justice: it is ordered to the good of those governed, not to the advantage of those governing. Examining one's own use of authority in family, workplace, or parish through this lens is a practical exercise in conformity to God's own kingship.
Verse 5 calls Catholics to deliberate, conscious worship — not rote recitation but genuine interior exaltation. Attending Mass "because it's Sunday" is not yet this. The imperative rômᵉmû asks whether our hearts are genuinely lifted — whether we arrive at the liturgy having prepared our minds, having silenced distractions, having recalled who it is we are addressing. The practical application: spend five minutes before Sunday Mass reading Psalm 99 in full. Let it raise the mind to the reality of the King whose justice is His love, and whose love seeks your exaltation in return.
Commentary
Psalms 99:4 — "The King's strength also loves justice."
The Hebrew underlying "strength" (ʿōz) carries the sense of royal power, might, and authority — the very force by which a king rules and by which wars are won. What is theologically arresting here is the verb ʾāhēb ("loves"): divine power is not merely constrained by justice as by an external standard, but actively desires it. God's omnipotence does not operate in moral neutrality; it is constitutively oriented toward justice (mišpāṭ). The pairing overturns every ancient Near Eastern model of kingship where might and justice were only loosely connected — where the strong king could be just but was not required to be. In Israel's faith, strength and justice belong to the same divine nature. The verse does not say God tolerates justice, or that He enforces it reluctantly. He loves it. This is affective language applied to God's governance of the cosmos, foreshadowing the New Testament revelation that God is Love itself (1 John 4:8), and that love and justice are not in competition within Him.
The final clause of verse 4 in the fuller Hebrew text adds that God "established equity" (mêšārîm) and "executed justice and righteousness in Jacob" — tying this cosmic claim about divine nature to the concrete history of the covenant people. God's love of justice is not abstract theology; it has written itself into the story of Israel through Torah, through the judges, through prophetic rebuke of unjust kings.
Psalms 99:5 — "Exalt Yahweh our God."
This imperative — rômᵉmû ("exalt," "lift up") — is addressed to the congregation of worshipers. The call to "exalt" the Lord is a liturgical summons: it echoes throughout the Psalter as an invitation to verbal, bodily, and communal praise. Crucially, the exaltation of God does not raise Him ontologically — He cannot be made higher than He is — but it raises the minds and hearts of the worshipers to recognize and confess His true stature. The Fathers would call this doxology in its most precise sense: giving glory not as something God lacks, but as what truthful creatures owe to the ground of all being.
Typological and Spiritual Senses
The Church Fathers read Psalm 99 as a Christological psalm. Eusebius of Caesarea and St. Augustine both identify the Kingship proclaimed in this psalm as belonging ultimately to Christ the King — the one in whom divine power and divine justice are not merely associated but hypostatically united. Christ is not just a righteous king; He Justice Incarnate (cf. Jer 23:6: "The Lord our Righteousness"). The call to "exalt" in verse 5 takes on Paschal resonance: Jesus is exalted in His Crucifixion (John 12:32), Resurrection, and Ascension — and the Church's praise liturgically participates in that exaltation. The ("Lift up your hearts") of the Mass mirrors precisely this Psalmic imperative: the Church answers "We lift them up to the Lord," performing in sacred action what verse 5 commands in sacred word.
