Doxology Closing Book I of the Psalter
13Blessed be Yahweh, the God of Israel, from everlasting and to everlasting! Amen and amen.
Psalms 41:13 is a doxological conclusion in which the psalmist transitions from personal lament about betrayal and deliverance to a public liturgical acclamation of God's eternal nature and covenant fidelity. The doubled "Amen and Amen" serves as the assembly's solemn ratification of praise directed toward Yahweh, the God of Israel, who exists from everlasting to everlasting.
This closing benediction seals not just one psalm but the entire first book of prayer—teaching that every lament must eventually arrive at praise.
The Fathers universally read the Psalms as the prayer of Christ. Athanasius wrote that the Psalter is the one book of Scripture in which the reader finds not merely words about the divine realities but words to speak before God. In this light, Psalm 41:13 is the voice of the total Christ (Christus totus, in Augustine's formulation) — Head and members — offering eternal praise to the Father. Christ, the true and ultimate Israel (cf. Matt 2:15; Hos 11:1), recapitulates and fulfills every prayer of the Psalter. His "Amen" — indeed, He is called "the Amen" in Revelation 3:14 — ratifies and perfects the prayer of Israel across all generations.
Catholic tradition illuminates this doxology with unique depth on several fronts.
The Structure of the Psalter as Sacred Pedagogy. The Church has always received the five-book division of the Psalter (Books I–V, mirroring the Pentateuch) as divinely ordered. Each book closes with a doxology (cf. Ps 72:18–19; 89:52; 106:48; 150), teaching the people of God that all prayer, however anguished or penitential, is oriented toward praise. The Catechism of the Catholic Church (§2589) notes that the Psalms "nourished and expressed the prayer of the People of God" and that praise is the prayer's final form. Book I's closing doxology thus teaches the interior structure of all Christian prayer: lament resolved in trust, trust crowned in praise.
"Amen" and the Eucharist. The double Amen carries profound Eucharistic resonance in Catholic life. St. Justin Martyr (First Apology, 65) records that the congregation's "Amen" at the close of the Eucharistic Prayer is the people's solemn ratification of the anaphora — their union with the priest's offering. St. Jerome observed, "The Amen resounds like heavenly thunder in the basilicas of Rome." The Catechism (§1065) teaches that Jesus Christ himself is the definitive Amen (cf. Rev 3:14), and that Christian prayer and liturgy are drawn into His perfect "Yes" to the Father.
Eternal Praise and the Beatific Vision. The phrase "from everlasting to everlasting" anticipates the Church's eschatological hope. St. Augustine, in the final books of The City of God, describes the eternal Sabbath as unceasing praise — the blessed crying "Amen, Amen" in perfect conformity with God's will. This verse is thus a foretaste of heaven itself, where the whole Church, triumphant, will bless the God of the New and Eternal Israel without end.
Every Mass ends — as it began — with praise of God. The double Amen of Psalm 41:13 places a concrete demand on the contemporary Catholic: prayer must not remain perpetually in the mode of petition or lament but must be trained, through discipline and trust, to arrive at praise. This is not naïve optimism but mature faith — the hard-won conviction that God is trustworthy even when circumstances seem to deny it.
Practically, a Catholic praying the Liturgy of the Hours encounters this doxology embedded in the structure of the Divine Office: each psalm ends with the Gloria Patri ("Glory be to the Father…"), which is the Christian form of exactly this benediction. Praying these doxologies attentively, rather than rushing through them, is a concrete spiritual exercise. Allow the double Amen to be a conscious act of the will — a ratification, however costly, of God's goodness over the day's actual experience of struggle, failure, or suffering. When the Amen is prayed honestly through difficulty, it becomes an act of heroic faith that unites the soul to Christ's own "Amen" offered on the Cross.
Commentary
Literal and Narrative Meaning
Psalm 41 itself is a psalm of David — a lament of the sick man abandoned by enemies and friends alike, yet rescued by God's fidelity. The body of the psalm reaches its resolution in verse 12, where the psalmist confesses that God has upheld him in his integrity. Verse 13 then pivots dramatically from personal lament and personal deliverance to cosmic, liturgical praise: "Blessed be Yahweh, the God of Israel, from everlasting to everlasting. Amen and Amen."
The pivot is structurally crucial. The Hebrew verb bārûk ("blessed") in this context functions as a declarative acclamation — an act of liturgical praise offered by the assembly. To "bless" God (unlike blessing a human) is not to confer something upon God but to acknowledge, proclaim, and celebrate who God already infinitely is. The formula mēhāʿôlām wěʿad hāʿôlām — "from everlasting to everlasting" — frames Yahweh's nature as boundless in both directions of time, reaching into an eternity prior to creation and forward into an eternity beyond history. This is no mere poetic hyperbole; it is a theological confession of God's aseity and eternal self-sufficiency.
The Double Amen
The verse closes with the striking liturgical formula ʾāmēn wěʾāmēn — "Amen and Amen." The word ʾāmēn derives from the Hebrew root ʾmn, meaning firmness, trustworthiness, truth. To say "Amen" is to ratify what has been said as true and to align oneself personally with it. The doubling of the Amen is not mere redundancy; in Hebrew literary convention it intensifies the affirmation — it is the congregation's solemn, unequivocal endorsement of the entire doxology and, by extension, of all the prayer of Book I. The Septuagint translates the double Amen faithfully (γένοιτο, γένοιτο), and this liturgical usage passed directly into Christian worship.
The God of Israel
The divine title Elohē Yisrāʾēl — "the God of Israel" — is laden with covenantal density. This is not a generic deity but the God who entered into a binding covenant with Abraham, Isaac, and Jacob; who revealed His personal name YHWH to Moses; who delivered Israel from Egypt; who established His throne in Zion. The doxology thus stands as a covenantal seal: all the psalms of Book I — their laments, their praises, their wisdom, their royal hymns — are offered to and ratified before the God who is Israel's covenant Lord.
