One Father, one Son, one Holy Spirit

The Text

This is the quietest verse in the creed, and it is doing precise work. After the relations of origin (verses 21–23) the creed draws an inference so obvious it can be read straight past: ergo — therefore — one Father, not three; one Son, not three; one Spirit, not three. It sounds like a truism. It is not. It closes a door the litany never closed.

The litany guarded against two errors: tritheism (three Gods) and modalism (the persons confounded into one). This verse guards against a third, subtler confusion — the multiplication or interchangeability of the persons themselves. If the doctrine has three persons, and “person” keeps getting repeated, a beginner can start to imagine the persons as a kind of divine office that might be filled more than once, or a set of roles that could in principle be reassigned. Verse 24 forecloses it. There is exactly one who is from no one. There is exactly one who is begotten. There is exactly one who proceeds. Each person is unrepeatable; the property that makes the Father the Father exists only once and cannot be handed to anyone else. The verse is the catechist’s anticipation of a real student error, answered before it can take root.

Translation Notes

ergo — “therefore.” The connective marks this as a deduction, not a new assertion. The creed has just named three unique relations of origin; the uniqueness of the relations entails the uniqueness of the persons. Verse 24 adds no content; it draws out what verses 21–23 already contained, so that no one mishears the relations as repeatable.

unus … non tres, inverted. The form is the litany’s, but the target has flipped. In verses 11–18, “not three” fenced the essential attributes (non tres aeterni — not three eternals; non tres dii — not three Gods). Here “not three” fences the personal names (non tres Patres — not three Fathers). This is the exact place to see why “three persons” is catholic but “three Fathers” is heresy: “person” is the word that counts the relations (there are three of them); “Father” is the name of one particular relation, which exists once and only once.

the incommunicability of the personal properties. The scholastic precision behind the verse is a single distinction. The divine essence is communicated wholly to each person — the Son is no less God than the Father, the whole Godhead is the Spirit’s. But the personal property is incommunicable: paternity is the Father’s alone and cannot be shared with the Son (the Son is not “partly Father”); filiation is the Son’s alone; passive procession the Spirit’s alone. Communicable essence, incommunicable property — that pair is the whole doctrinal payload of verse 24, and it is what blocks every picture of the persons as swappable roles.

Historical Context

The incommunicable idiōmata. The Cappadocians had already named the distinguishing properties as incommunicable: only the Father is agennētos (unbegotten), only the Son gennētos (begotten), only the Spirit the one who proceeds. Augustine carried the point into the Latin grammar of relation. Verse 24 is that patristic settlement stated as a corollary a beginner can hold: the properties do not come in threes.

Lateran IV, once more. The error this verse pre-empts is, structurally, the one the Fourth Lateran Council (1215) had to condemn in Joachim of Fiore: a miscount of the Godhead — treating the divine reality as something that could be summed, divided, or multiplied. The Council insisted the divine essence is neither divided nor multiplied by the persons. Verse 24 is the same guard, applied not to the essence (one God, not three) but to the persons (one Father, not three) — the two halves of a single refusal to let God be counted like creatures.

Why a creed bothers with the obvious. That the Quicumque spends a verse denying “three Fathers” is itself evidence of its genre. This is not a conciliar decree settling a live heresy; it is a catechetical instrument, written to be chanted and learned, which anticipates the predictable misreadings of the half-instructed and closes them in advance. The very triviality of the verse is the proof that the creed is teaching, not merely defining.

Lines of Interpretation

This is the least contested verse in the creed; no tradition disputes that there is one Father, one Son, one Spirit. The interpretive interest lies downstream of the incommunicability it states — especially in the modern question of whether the personal names are themselves incommunicable and so non-substitutable.

Patristic

Tradition: the Cappadocian idiōmata; Augustine, On the Trinity V

The Fathers fixed the properties as incommunicable and unique: the marks that distinguish the persons cannot be transferred, or the persons would collapse into one another.

Strengths

• Secures real, irreducible distinction without dividing the one essence
• Explains precisely why the persons cannot be confounded and cannot be multiplied

Weaknesses

• The communicable-essence / incommunicable-property distinction is subtle and rarely survives intact into popular teaching
• Stated only negatively, it tells you the properties cannot be shared without saying what they positively are

Scholastic

Tradition: Thomas Aquinas, Summa Theologiae I qq. 32–33, 40 (the personal properties); Richard of St Victor, De Trinitate

Aquinas gives the verse its exact form: a proprietas personalis is, by definition, incommunicable — that is what makes it constitutive of this person and no other. The essence is shared integrally; the property is what the sharing cannot reach.

Strengths

• The most precise available account of why each person is unrepeatable — uniqueness follows from the very notion of a personal property
• Cleanly distinguishes what is one because essential (God) from what is one because it is a singular relation (Father)

Weaknesses

• The technical apparatus is far from the worshipper’s experience of Father, Son, and Spirit
• “Incommunicable property” can sound like a logical token rather than the living distinctness of the Three

Eastern Orthodox

Tradition: the Cappadocians; the monarchia of the Father

The East reads unus Pater with particular weight: the one Father is not only one relation among three but the unique source — the unoriginate from whom the Son is begotten and the Spirit proceeds. The incommunicable agennēsia of the Father grounds the unity of the Godhead in a person, not in an abstract essence.

Strengths

• Keeps the unity personal and concrete — one God because one Father, the fount of deity
• Honors the verse’s unus Pater as theologically loaded, not merely a tidy corollary

Weaknesses

• The strong source-reading must be stated carefully lest the Father’s uniqueness imply the Son’s and Spirit’s lesser deity — which the litany has already forbidden
• Western readers hear unus Pater as one relation within one essence, and the difference of accent feeds the older East–West tension

Reformed / Western

Tradition: Francis Turretin, Institutes of Elenctic Theology III; the Reformed scholastic doctrine of personal properties

The Western inheritors read the verse mainly as anti-confusion and anti-Joachite hygiene: one Father because one paternity, within the one simple essence; the properties incommunicable, the essence wholly common.

Strengths

• Keeps the verse in its modest place — a guard against miscount, not a fresh doctrine
• The communicable/incommunicable distinction is stated with confessional clarity

Weaknesses

• Treating the verse as mere hygiene can miss the unus Pater the East hears as load-bearing
• Reformed precision sometimes multiplies scholastic distinctions where the creed deliberately stops

Modern / Ecumenical

Tradition: the divine-naming debate — Wolfhart Pannenberg; Elizabeth Johnson, She Who Is (the feminist critique); the catholic-trinitarian reply (Soskice; Kimel, ed., Speaking the Christian God)

The modern question is whether the names — Father, Son — are themselves incommunicable in the way this verse’s logic implies. One side argues that the names function within an idolatrous sacralizing of masculinity and should be revisable (often: “Creator, Redeemer, Sustainer”). The other replies that Father, Son, and Spirit name eternal relations, not works or genders, and are therefore exactly as non-substitutable as verse 24 says the persons are; replacing them with task-words names the works of the one God and so re-creates the modalism the creed forbids.

Strengths

• The critique rightly exposes a real idolatry — the literalizing of divine masculinity, which Scripture itself denies (“God is not a man”)
• The reply rightly sees that verse 24’s logic is decisive: relational names are incommunicable; function-names (“Creator/Redeemer/Sustainer”) are interchangeable because they name works, and interchangeable role-words are modalism

Weaknesses

• The substitutionary proposals, whatever their pastoral motive, collide with this verse: they name what the one God does, not the relations the three eternally are, and so cannot do the work the personal names do
• The defense, if it stops at “the names are given,” can fail to address the genuine pastoral wound the critique names, leaving the impression that the doctrine is indifferent to it — which it is not

Wesleyan Voice

The verse’s accent — one Son, not three — is, for the Wesleyan tradition, not a logical tidiness but the very hinge of the gospel of adoption. Wesley’s soteriology turns on the difference between the one, unique, eternal Son and the many who are made sons in him. Romans 8 is the Wesleyan map: the Son is “the firstborn among many brethren” (8:29); we receive “the Spirit of adoption” and cry “Abba, Father” (8:15); we are “heirs of God and joint-heirs with Christ” (8:17). Every clause depends on verse 24. There are not three Sons — and there are not, by grace, additional sons of the same rank as the eternal Son. There is one Son, and the good news is that we are taken into his sonship: our standing before the Father is not a second, rival filiation but participation in the single, unrepeatable one. Wesley’s Sermon 9, The Spirit of Bondage and of Adoption, is the pastoral exposition of exactly this: the believer’s sonship is real because it is the one Son’s, shared.

This is why the uniqueness of the persons is, for Wesley, liberating rather than abstract. Because there is only one Son and I am not he, my acceptance with God is not my achievement, not my originality, not a status I must generate and could lose. It is his, and it holds because it was never mine to keep. The incommunicability of the Son’s filiation is the security of the adopted: what cannot be communicated as a property is, astonishingly, shared as a gift — we are sons “in the Son,” and the foundation does not move because it is not ours.

Wesley used the names Father, Son, and Spirit as given, fixed, and scriptural, and his “fact, not the manner” discipline (Sermon 55) kept him from theorizing the personal properties while holding their distinctness without compromise. He would have resisted refashioning the relational names — not to baptize a human father-image, but because the gospel of adoption requires that there be exactly one Son into whose unique relation we are brought. Charles Wesley sang it precisely: “Arise, my soul, arise, / shake off thy guilty fears … before the throne my surety stands … my name is written on his hands” — one Son, one surety, and our names safe in his, not beside his.

Hymnody

Verse 24 itself — “not three Fathers, not three Sons” — is not a hymn subject; you do not sing a corollary. What the hymnody sings, richly, is the truth the corollary protects: that there is one Son, and that our whole standing is to be made sons in him.

Charles Wesley’s “Arise, my soul, arise” is the verse turned to assurance: the one Son as the believer’s “surety” before the throne, the adopted heard because the one Son is heard. “And can it be” names the gift by its proper word — “adoption” — the many brought into the place of the one. “O come, all ye faithful” confesses the Son “only-begotten,” the monogenēs uniqueness this verse guards. “Of the Father’s love begotten” sings the single, unrepeatable Son “ere the worlds began to be.”

And the verse’s positive form is in every baptism the church sings around: the one Name — “the Father, and the Son, and the Holy Spirit” — never pluralized, never reassigned, the fixed and relational Name into which each Christian is named. The hymnody does not argue that there are not three Sons; it sings the one Son, and the adoption that makes that uniqueness the best news a person can hear.

Pastoral and Liturgical Use

This unobtrusive verse carries one of the most freeing pastoral truths in the creed, and one of its most delicate teaching tasks.

Preach the uniqueness of the Son as the security of the adopted. The modern self labors under a quiet, exhausting commission: to be its own unique son — self-made, self-authenticated, the irreplaceable exception who must generate and defend its own standing. Verse 24 says, gently, that there is exactly one unique Son, and you are not him. To a culture of self-authentication that sounds like bad news; the gospel makes it the best news available. You do not have to be the Son. You are loved in him. Your acceptance with God is not your achievement competing for scarce approval; it is participation in the one Son’s own unlosable place — “heirs of God, and joint-heirs with Christ.” The pastoral task at the bedside, with the failing and the ashamed, is exactly this: your name is safe because it is written on his hands, not your own, and what is incommunicable as his property has been communicated to you as sheer gift. There is one Son; you were adopted into him; that foundation cannot be moved because you were never the one holding it up.

Name the idol, then teach the names with care. The verse’s incommunicability also bears on the contested question of how the church names God, and a pastor should handle it the way the creed handles everything — precisely, and pastorally, not polemically. First, name the real idol the critique rightly exposes: God is not male; “Father” does not sacralize human fatherhood or men’s authority, and wherever the church has used it to do so it has sinned and should repent. Then teach what verse 24 actually secures: Father, Son, and Spirit are not job descriptions but the names of eternal, incommunicable relations. This is why they cannot simply be swapped for “Creator, Redeemer, Sustainer.” Those are good words for what the one God does; they are not the names of the three who God is, and using them as substitutes quietly reinstalls the modalism this very creed (verses 4 and 24) was built to exclude — one God doing three jobs, rather than Father, Son, and Spirit. The pastoral skill is to hold both truths without flinching from either: the church keeps the given relational names not to defend an idol but to refuse one (modalism), and a congregation taught this carefully is freed from both errors at once.

Let the font do the teaching. The pastor does not need an argument; the church already keeps verse 24 at every baptism. “I baptize you in the name of the Father, and of the Son, and of the Holy Spirit” — one Name, three relations, never pluralized, never reassigned. Point at it once and say what it means: this child is being named into the one Son, by the one Spirit, before the one Father; not three Fathers, not a fourth son, not a set of roles — the single, fixed, relational Name, into which the whole church has been named, and out of which no adopted child can fall.
