Colossians 2:9 — “in him the whole fullness of deity dwells bodily”: communicated fullness, not consubstantiality
“In him the whole fullness of deity dwells bodily” is traditionally regarded as the single strongest proof-text for the essential godhead of Christ. Read in the Socinian way, the sentence says precisely the opposite: a fullness that dwells in someone is not his own by nature but poured into him — and the immediately following verse (2:10: “and you have been filled in him”) passes on this very fullness, by measure, to the congregation. But the divine essence cannot be possessed in part. The word “bodily” (sômatikôs) moreover stands in contrast to the “shadow” of the law (2:17) and means “really and firmly,” not “in a fleshly divine nature.” What is meant is the whole fullness of divine wisdom, authority, and knowledge of God’s will, which God has laid down in Christ as the head.
“For in him the whole fullness of deity dwells bodily, and you have been filled in him, who is the head of all rule and authority.”
Colossians 2:9–10
Context
Colossians 2 is Paul’s defense against a “philosophy and empty deceit” (2:8) that sought to force the congregation, by way of elemental powers, angel-worship, dietary rules, and a festival calendar, back under a pre-Christian religiosity. Against this Paul sets Christ as the one “in whom are hidden all the treasures of wisdom and knowledge” (2:3). Verse 9 thus stands in a polemical, not a speculative-trinitarian, context: the point is that in Christ one has everything and needs nothing besides.
The arc of the sentence in 2:8–10 is a unity: warning against the philosophy (v. 8) — the ground “for in him the whole fullness of deity dwells bodily” (v. 9) — the conclusion “and you have been filled in him” (v. 10). The fullness that dwells in Christ and the fullness with which the Colossians are “filled” are, linguistically (plêrôma / peplêrômenoi) and substantively, one and the same magnitude. Whoever understands v. 9 of the indivisible divine essence tears this arc apart.
The nearest parallel stands in the same letter: 1:19, “for it pleased (eudókêsen) God that in him all the fullness should dwell.” The “it pleased” makes the indwelling a free act of God’s appointing; something that God graciously bestows upon another is not that other’s own essence. The two passages explain one another.
The “bodily” (sômatikôs) is to be read in light of 2:17, where the law with its feasts and foods is called “a shadow of what is to come,” “but the body (sôma) belongs to Christ.” Shadow and body form a contrasting pair: in the law the divine truth was shadowy, in Christ it is really and firmly present. “Bodily” therefore means “in full reality,” not “in a divine fleshly body.”
The Socinian core thesis
In the Socinian reading, Col 2:9 is a high point of Christocentrism, not of an essential Trinity: in Christ the whole divine self-communication is laid down — all wisdom, all saving authority, the full and firm knowledge of the divine will. Whoever has him has God fully disclosed and needs no “philosophy” alongside.
The decisive point is the verb: the fullness dwells (katoikei) in him. A dwelling presupposes two — the one who dwells, and the one in whom dwelling takes place. Where the divine essence simply were, one could not say it “dwells” in someone; God does not dwell in God. Christ is here the bearer, the temple, in whom the fullness of God takes up its dwelling (cf. John 14:10: “the Father who dwells in me”).
That it is a matter of a communicable fullness, the text itself says: “and you have been filled in him” (2:10). What Christ fully possesses, believers receive from him according to their measure — just as John puts it: “from his fullness we have all received” (John 1:16), and as Paul wishes for the Ephesians, that they might be “filled with all the fullness of God” (Eph 3:19). The indivisible essence of God cannot be portioned out in this way; a communicated fullness of divinity very well can.
“Deity” (theótês) here accordingly designates not the essential nature, but the full divinity in the sense of divine authority, wisdom, and disclosure of the will — precisely that which, according to 2:3, lies hidden in Christ as “all the treasures of wisdom and knowledge” and passes over from him to the congregation.
A fullness that dwells in someone and is passed on from him to others (2:10) is not that one’s indivisible essence, but God’s gift to him. Col 2:9 crowns Christ as the head in whom God has laid down his whole saving fullness — not as a second divine essence.
Exegesis: key terms and word field
Four key terms decide the interpretation of Col 2:9 linguistically:
plêrôma — “fullness”
Plêrôma is consistently, in Paul, a term of communication and participation. Eph 3:19 (“filled with all the fullness of God”), Eph 4:13 (“to the measure of the fullness of Christ”), John 1:16 (“from his fullness we have all received”) — everywhere the word designates a fullness that flows from one to others.
Therein precisely lies the argument: a “fullness” implies that the same thing can also occur elsewhere in lesser measure — otherwise the word “full” would be meaningless. But the divine essence knows no more and less; one possesses it wholly or not at all. Consequently, by the “fullness of deity” the essence is not meant, but a divinity communicable by degrees.
The Racovian Catechism draws exactly this line: the same fullness that dwells in Christ as the head is “transferred to the members according to each one’s measure and capacity” (cf. Col 2:10; Eph 4:7).
theótês — “deity” / “divinity”
The Greek theótês (θεότης) can designate both the “deity” in the sense of the divine essence and the “divinity” in the sense of divine properties and authority. Which meaning applies is decided not by the vocabulary word but by the context.
But the context here is polemical-practical: Paul sets Christ against the “philosophy” and the “law” (2:8, 16–17). He therefore speaks of that divinity “which is transferred to us from him himself through his teaching and his Spirit” (Racovian Catechism) — that is, of the true heavenly wisdom and the firm knowledge of the divine will, not of an essential nature.
That Paul calls the same thing two verses earlier “all the treasures of wisdom and knowledge” (2:3) confirms this reading: theótês means the complete disclosure of God laid down in Christ, not a second divine substance.
sômatikôs — “bodily”
The adverb sômatikôs is traditionally read as “in bodily form” and thus as proof of the incarnation of the divine essence. Yet Paul himself supplies the key: in 2:17 he calls the law a “shadow (skia),” “but the body (sôma) belongs to Christ.”
Shadow and body thus form a fixed contrasting pair: what in the law was only prefigured in shadow is in Christ really and firmly present. “Bodily” accordingly means “truly and substantially” in contrast to the mere shadow — not “in a divine fleshly body.” The point is one of salvation history (law/shadow versus Christ/reality), not ontological.
katoikei — “dwells”
The verb katoikei (“dwells,” present tense, lasting indwelling) presupposes a distinction between the one dwelling and the place of dwelling. God does not dwell in God; an essence does not dwell in itself.
John uses the same dwelling-language for the relation of Father and Son: “the Father who dwells (menôn) in me does the works” (John 14:10). Indwelling is relation, not identity. Thus Christ is the man in whom the whole fullness of God has taken up its dwelling — the temple, not the deity itself.
Comparison of the interpretations
Reference to Fausto Sozzini
Sozzini does not deny that the whole fullness of deity dwells in Christ — he determines what that means. In his Antitheses against Francis David he reads Col 2:9 functionally: that the whole fullness of deity dwelt in Christ is shown by the fact that his teaching is to be taken as God’s own word.
… since he was the express image of God and in him the whole fullness of deity dwelt bodily, so that in his teaching he spoke not a single word that is not to be regarded as spoken by God himself with his own mouth.
Fausto Sozzini, ‘On the Honour of Christ’, Antitheses against Francis David, Thesis 1
Sozzini thus interprets the indwelling of the divine fullness not as a second essential nature but as the unconditional authority of Christ’s teaching: because God’s whole fullness dwells in him, every word of his proclamation is God’s word. This is a soteriological and revelation-theological statement, not an ontological one.
The Racovian Catechism develops the same thought philologically. On Col 2:9 it states there: “Nor is that divine nature proved by those words, that the fullness of deity dwells in him bodily. For … he [speaks] of that deity or divinity of Christ … which is transferred to us from him himself through his teaching and his Spirit.” The word “fullness” itself, it argues, indicates that a communicable, gradable divinity is in view — which does not apply to the divine essence.
And, decisively, likewise from the Racovian Catechism: “But the fullness of God and the fullness of deity are the same, although it dwells first and by far more abundantly in Christ as the head, and through him is then transferred to the members according to each one’s measure and capacity.” With this, Col 2:10 (“and you have been filled in him”) is recognized as the commentary on v. 9 supplied by the apostle himself.
Overview of the writings of Sozzini
Logical arguments
From the wording and context of Col 2:9–10 the following arguments arise against the consubstantial reading:
- Argument from the immediately following verse. 2:10 says “and you have been filled in him (peplêrômenoi).” The same fullness that dwells in Christ passes over to the congregation. But the divine essence cannot be transferred to the Colossians. Therefore the essence is not meant.
- Argument from the term “fullness.” A fullness presupposes that the same thing can be present elsewhere in lesser measure. The essence of God knows no more or less. Consequently “fullness of deity” designates a communicable divinity, not the essential nature.
- Argument from the dwelling. The fullness dwells in Christ (katoikei). Dwelling presupposes a distinction of the one dwelling and the dwelling-place; God does not dwell in God. Christ is the bearer in whom God takes up his dwelling — like the Father “who dwells in me” (John 14:10).
- Argument from “bodily.” Sômatikôs stands in contrast to the “shadow” of the law (2:17: skia versus sôma). It means “really and firmly,” not “in divine flesh.” The contrast is one of salvation history (shadow/reality), not metaphysical.
- Argument from the context of philosophy. 2:8 warns against “philosophy and empty deceit.” Paul extols Christ as the place of “all the treasures of wisdom and knowledge” (2:3). The “deity” named in v. 9 is precisely this divine wisdom fully disclosed in Christ.
- Argument from Col 1:19. The parallel says: “it pleased (eudókêsen) God that in him all the fullness should dwell.” A free act of God’s appointing (“it pleased”) confers the indwelling — what God graciously gives to another is not that other’s own essence.
- Argument from the scriptural parallel. John 1:16 (“from his fullness we have all received”) and Eph 3:19 (“filled with all the fullness of God”) use the same fullness-language of a given, shared divine fullness. Col 2:9 is to be read by the same rule.
- Argument from the lexicon. Theótês is ambiguous (essence or property). A consubstantial reading must first be grounded from the context — and the context (philosophy, law, head-members communication) does not bear it but refutes it.
- Argument from function (Sozzini). Sozzini interprets the indwelling of the whole fullness as meaning that no word of Christ’s teaching is to be taken otherwise than as God’s own word. This is a statement about Christ’s authority and rank of revelation, not about a second essential nature.
Biblical cross-references
The following passages are essential for the right understanding of Col 2:9:
Colossians 2:10 — “and you have been filled in him”
The commentary on v. 9 supplied by the apostle himself. The fullness that dwells in Christ is passed on to the congregation (peplêrômenoi). A magnitude that can be distributed to the Colossians “according to their measure” is not the indivisible divine essence.
Colossians 2:3 — “all the treasures of wisdom and knowledge”
Two verses earlier Paul determines what the “deity” consists of that dwells in Christ: in the divine wisdom and knowledge fully hidden in him. This is the disclosure of God, not a second substance.
Colossians 1:19 — “it pleased God that in him all the fullness should dwell”
The nearest parallel. The “it pleased” (eudókêsen) makes the indwelling a free act of God’s grace with the goal of reconciliation (1:20). What God graciously places into another is gift and commission, not essence.
John 1:16 — “from his fullness we have all received”
The same fullness-language (plêrôma): from Christ’s fullness believers receive “grace upon grace.” A fullness from which one receives is communicable — a key to the reading of Col 2:9.
Ephesians 3:19 — “filled with all the fullness of God”
Paul wishes the Ephesians themselves to be filled with “all the fullness of God.” This makes clear that “fullness of God” is, for Paul, something that people can receive — not the essence of God closed off to them.
John 14:10 — “the Father who dwells in me”
John’s dwelling-language shows: indwelling is relation, not identity. The Father dwells in the Son and works through him; just so the fullness of deity dwells in Christ without making him the essence-God.
John 3:34 — “God gives the Spirit without measure”
Of Christ it holds that the Spirit is given to him “without measure” — that is, in fullness. Yet it is a given thing: Christ receives the full endowment from God. This is precisely what the “whole fullness” in Col 2:9 means.
Objections and Socinian answers
Objection 1: “Theótês means precisely the essence, not merely a property!”
Theology sharply distinguishes theótês (Col 2:9, essential godhead) from theiótês (Rom 1:20, mere divinity). Paul chooses the stronger word — therefore the essential godhead of Christ is meant.
The asserted sharp distinction between the two words is not linguistically secured; in ancient Greek theótês and theiótês overlap considerably, and theótês can equally designate divinity as a term of property and authority.
Even if one renders theótês with “deity,” it is decided not by the vocabulary word but by the sentence: this deity dwells in Christ and is, according to 2:10, passed on to the congregation. An essence can neither “dwell” in its bearer nor be transferred in portions.
The context (2:8, 16–17) aims at wisdom against philosophy and reality against legal shadow, not at essential metaphysics. The choice of word alone does not bear the dogmatic load that is laid upon it.
The Racovian Catechism therefore holds that “that divine nature is not proved”; the word “fullness” itself indicates a gradable, communicable divinity, “which does not apply to the divine essence.”
Objection 2: “‘Bodily’ means the bodily incarnation of the deity.”
Sômatikôs means “bodily.” Paul thus says that the divine essence became bodily, corporeally present in Christ — the incarnation of God.
Paul himself supplies the contrasting term in the same chapter: 2:17 calls the law a “shadow (skia),” “but the body (sôma) belongs to Christ.” Sôma/shadow is the pair real/provisional.
From this, sômatikôs means “in full reality, substantially, firmly” — in contrast to the shadowy prefiguration in the law. It is a term of salvation history, not an anatomical one.
The statement therefore runs: what the law possessed only in shadow is in Christ really and firmly laid down — the full, real presence of the divine saving fullness. This is precisely not a proof of a bodily essential godhead.
The traditional reading must blank out the context 2:16–17 in order to interpret sômatikôs as incarnation. Whoever leaves the context standing arrives at the meaning “really/firmly.”
Objection 3: “Why then the whole fullness, if it were only a matter of wisdom?”
If only divine authority and wisdom were meant, the “whole” (pan to plêrôma) would have to be superfluous. The “all” shows that the undivided godhead is meant.
The “whole” marks the completeness of revelation in Christ as the head: in him nothing of the divine saving fullness is lacking, so that one needs no “philosophy” and no angelic powers besides him (2:8, 18). This is precisely Paul’s concern.
The fullness is “whole” in Christ precisely because it is distributed from him to the members: Eph 4:7, “to each one grace was given according to the measure of Christ’s gift.” The head has the whole, the members their measure.
“Whole fullness” and communicability therefore do not exclude one another but condition one another: Christ possesses completely what he allots to his own. The Racovian Catechism formulates exactly this: the fullness dwells “by far more abundantly in Christ as the head” and is passed on through him.
An indivisible essence would gain nothing from the addition “whole” — one cannot have the essence of God “in part.” The “whole” makes sense only with a gradable fullness.
Objection 4: “Col 1:19 says the same and proves the godhead all the more.”
“In him all the fullness was pleased to dwell” (1:19) is the parallel to 2:9 and shows that the whole godhead is lastingly, essentially present in Christ.
1:19 confirms the Socinian reading rather than refuting it. The verse says: “it pleased (eudókêsen) God” that the fullness should dwell in Christ. A “good pleasure” is a free act of God’s will that posits something — not an expression of natural essential identity.
The subject of the positing is God (the Father); Christ is the one in whom the fullness is appointed to dwell. With this, Christ is recipient and bearer, not himself the positing divine essence.
The goal of the indwelling is named expressly by 1:20: “and through him to reconcile all things.” The fullness dwells in Christ for a mediatorial, saving purpose. An essential godhead would need no such ground of appointment.
Both verses together therefore yield: God freely and purposefully lays his whole saving fullness into the man Christ — the opposite of an innate essential godhead.
Objection 5: “Then Christ is only a great teacher.”
If only divine wisdom and authority “dwell” in Christ, he is a gifted man among others — which does not do justice to the exalted language of Col 2.
The inference is false. Col 2:10 calls Christ in the same breath “the head of all rule and authority”: he stands above all cosmic powers, before which the false teachers were afraid. This is a singular position surpassing everything.
In him dwells the whole fullness — not a part, as with prophets and saints. Christ is the one mediator in whom God has disclosed himself fully and finally; from his fullness all others live (John 1:16).
Socinian Christology is therefore not “low” but exalting: God has appointed this man as head over all things, given him his name, his authority, and his whole saving fullness (Phil 2:9; Matt 28:18).
What is rejected is solely the metaphysical thesis of consubstantiality — not the height, uniqueness, and worthiness of worship of Christ, which, according to Scripture, rests on his position conferred by God (cf. John 5:23).
Theological consequences

The following passages support, deepen, or contrast the interpretation presented here:
- Colossians 1:15-17 — The same letter: Christ as “image of the invisible God” — representation, not essential identity.
- John 5:23 — Bestowed, not essential, honour; the same logic of the dignity of Christ conferred by God.
- 1 Corinthians 8:6 — The one God is the Father; the one Lord Christ is subordinated to him, not consubstantial.
- Hebrews 1:1-2 — “Imprint of his nature”: an imprint presupposes an original — Christ represents God, is not God himself.
- John 10:29 — Father and Son “one” in working and protection, not in essential nature.
Summary
Colossians 2:9 is, linguistically and in context, a high point of Christocentrism, not of an essential Trinity. The “fullness of deity” dwells in Christ (relation, not identity) and is, according to the immediately following verse 2:10, passed on to the congregation in a “filling” way — a process that would be impossible with the indivisible divine essence. “Bodily” means “really and firmly” in contrast to the legal shadow (2:17), not a bodily essential godhead.
The parallel 1:19 (“it pleased God that in him all the fullness should dwell”) makes the indwelling a free, purposeful act of God’s appointing — and the scriptural parallels John 1:16 and Eph 3:19 show the fullness-language consistently as the language of a given, shared divine fullness. “Deity” (theótês) here accordingly means the full divine wisdom, authority, and knowledge of the will, which according to 2:3 lies hidden in Christ as “all the treasures of wisdom and knowledge.”
Sozzini and the Racovian Catechism therefore read the verse functionally and in terms of revelation: in Christ dwells God’s whole saving fullness, so that no word of his teaching is to be taken otherwise than as God’s own word, and all the members live from his fullness. This is a high statement, exalting Christ above all powers — but not a thesis of consubstantiality; rather, the confession of the one God who has laid down his whole fullness in the man Christ whom he has exalted.
