A critical response to Bernard's The Oneness of God


Bernard's work is, in the kindest possible reading, a theologically motivated exercise in confirmation bias dressed up in the costume of systematic theology. He sets out not to discover what the Bible teaches about God but to defend a conclusion already reached. The result is a book riddled with logical fallacies, selective use of evidence, category errors, and interpretive sleight of hand. What follows is a chapter-by-chapter and argument-by-argument analysis. References are drawn from Boyd's Oneness Pentecostals and the Trinity, Grudem's Systematic Theology, and Geisler's Come Let Us Reason Together.
The False Dilemma Framework (Chapter 1)
Bernard opens by cataloguing four views of the Godhead and then systematically eliminates three of them to make Oneness the only viable option. This is a textbook false dilemma (also called a false dichotomy). His taxonomy:
- Trinitarianism
- Binitarianism
- Strict monotheism that denies Christ's full deity (Arianism/Dynamic Monarchianism)
- Oneness — strict monotheism with full deity of Christ (his position)
The problem is that he has rigged the taxonomy. He frames Trinitarianism as functionally tritheistic — or at best incoherent — and then presents Oneness as the only alternative that preserves both monotheism and Christ's full deity. This is profoundly dishonest. Orthodox Trinitarianism explicitly affirms:
- One divine essence/nature (ousia)
- Three distinct persons (hypostases) sharing that one essence
- No division of the divine being
Bernard simply assumes that three persons = three gods, which is precisely the point in dispute. He has not refuted Trinitarianism — he has caricatured it. As Geisler notes in Come Let Us Reason Together, a false dilemma "presents only two options when in reality more exist." Bernard's quadripartite taxonomy is designed to funnel the reader toward a predetermined destination, not to honestly represent the landscape.
Boyd addresses this directly: Oneness theology consistently confuses the distinction between "person" and "being." Three persons in one divine being does not equal three gods any more than three human persons sharing one human nature equals three humanities. Bernard never grapples with this distinction seriously.
Misuse of the Shema (Deuteronomy 6:4)
Bernard treats the Shema — "Hear, O Israel: the LORD our God is one LORD" — as a slam-dunk against Trinitarian theology. He writes:
- "Surely, God could not make it plainer that no plurality whatsoever exists in the Godhead."
This is exegetically sloppy for several reasons:
The Hebrew Word Echad
The word translated "one" in Deuteronomy 6:4 is echad (אֶחָד), which does not denote absolute mathematical singularity. Hebrew has another word — yachid (יָחִיד) — for that concept, meaning "solitary" or "only one." Significantly:
- Echad is used in Genesis 2:24: "and they shall become one (echad) flesh" — a compound unity of two persons.
- Echad is used in Genesis 11:6: "the people is one (echad)" — a collective unity.
- Echad is used in Ezekiel 37:17, where two sticks become "one (echad)"—a clear composite unity.
If God had intended to assert absolute numerical singularity — ruling out any plurality within the divine nature — He could have used yachid. He didn't. Bernard never interacts with this distinction, which Grudem addresses in Systematic Theology (pp. 226–227). This is not a minor lexical quibble; it is the entire foundation of Bernard's Chapter 1 argument.
The Jewish Argument is Self-Defeating
Bernard appeals to Jewish rejection of Christianity as evidence that Trinitarianism distorts monotheism. This argument is irredeemably weak:
- Judaism also rejects Jesus as Messiah, the Virgin Birth, and the Resurrection. Bernard does not take those Jewish rejections as normative.
- Second Temple Judaism was not monolithic — there were well-documented intra-Jewish debates about divine agency, the "two powers in heaven" tradition (Alan Segal), and personified divine attributes (Wisdom, Word, Spirit) that anticipated Trinitarian categories.
- The New Testament itself (written entirely by Jews) uses language about Jesus that the earliest Jewish believers — who were all monotheists — did not see as compromising monotheism.
The argument proves too much or nothing at all.
Bernard Ignores Trinitarian Interpretations of the Shema
New Testament writers — themselves monotheistic Jews — actually cite the Shema in ways that implicitly include Jesus. The most striking example is 1 Corinthians 8:6:
- But to us there is but one God, the Father, of whom are all things... and one Lord Jesus Christ, by whom are all things.
Paul is here re-reading the Shema ("the LORD our God is one LORD") distributively — allocating "God" to the Father and "Lord" (the Shema's second YHWH) to Jesus. This is not a contradiction of monotheism; it is a Christological expansion of it.
Bernard quotes 1 Corinthians 8:6 but uses only the Father clause while ignoring the structural parallel that identifies Jesus with the Shema's second LORD. This is selective quotation — a variant of the suppressed evidence fallacy.
The "Strongest Possible Language" Argument
Bernard argues that God, by using language like "none, none else, none beside me, alone," is ruling out any plurality within the Godhead. His rhetorical question:
- "What strong words could He use to get His message across? ... Surely, God could not make it plainer that no plurality whatsoever exists in the Godhead."
This argument commits the non sequitur fallacy. The "none beside me" language in Isaiah is directed against other gods — pagan deities, idols, foreign divine competitors. It is not addressing the internal structure of God's own being. The question the Isaiah passages answer is: "Are there other gods besides YHWH?" The answer is an emphatic no. But that is an entirely different question from: "Is the divine being simple and absolutely singular, admitting no distinctions of persons?"
Boyd makes this point forcefully: Oneness theology consistently conflates numerical monotheism (there is only one God, not many gods) with absolute divine simplicity (God has no internal distinctions whatsoever). The Bible teaches the former emphatically. It does not teach the latter, and the New Testament evidence actively contradicts it.
The Modalism Problem Bernard Acknowledges but Doesn't Solve
Bernard openly identifies his view with historical modalism — the position of Noetus, Praxeas, and Sabellius — while trying to distance himself from the pejorative label. He writes that Oneness believers see "Father, Son, and Holy Spirit are manifestations, modes, offices, or relationships that the one God has displayed to humans." This is Sabellian modalism — the view condemned as heresy at the Council of Rome (c. 262 AD) and repeatedly thereafter. Bernard's rhetorical strategy is to repackage it under the term "Oneness" while dismissing the historical condemnation as the product of Greek philosophical corruption rather than scriptural fidelity (an argument he develops later). But this is an ad hominem circumstantial fallacy — dismissing a conclusion based on the alleged motives of those who reached it, rather than engaging the arguments on their merits.
More critically, modalism creates insurmountable exegetical problems that Bernard never adequately resolves:
- Matthew 3:16-17 — At Jesus' baptism, the Father speaks from heaven while the Son is in the water and the Spirit descends as a dove. Three simultaneous, distinct, and differentiable presences. A modal reading requires either that the "voice" and "dove" are theatrical props with no real ontological referent, or that God was performing an elaborate charade for the benefit of the audience.
- John 17:1-26 — Jesus prays to the Father at length. If the Father and Son are merely modes of the same person, this prayer is either incoherent soliloquy or — more disturbing — God performing a theatrical conversation with Himself to deceive observers about the nature of prayer. Bernard's response (that Jesus' human nature prays to His divine nature) creates a second problem: it makes Jesus schizophrenic and essentially splits Him into two persons — which is Nestorianism, a different heresy.
- Mark 15:34 — "My God, my God, why hast thou forsaken me?" If Father and Son are one person in modes, this cry is ontologically impossible. A person cannot forsake himself. Bernard's human/divine nature dodge again splits Christ in ways incompatible with Chalcedonian Christology — though Bernard would likely regard that as a feature, not a bug.
Grudem (Systematic Theology, pp. 241–243) notes that modalism cannot account for the genuine personal distinctions visible throughout the Gospel of John, where Jesus speaks of the Father in the third person, the Father speaks of the Son, and the Spirit is promised by Jesus as another (allos — same kind) Comforter distinct from Himself.
The Definitional Shell Game with "Person"
Bernard attacks the Trinitarian use of "person" by arguing it implies three separate centers of consciousness, three wills, three beings — in short, tritheism. He writes that trinitarianism leads to a "weakening of strict monotheism." But this is a straw man.
The Trinitarian doctrine of hypostasis does not mean "person" in the modern psychological sense of an autonomous, self-contained individual ego. The Cappadocian Fathers, who refined Trinitarian vocabulary in the 4th century, used hypostasis to mean a distinct mode of subsisting within the one divine being — not an independent being. Bernard exploits the modern connotation of "person" to make Trinitarianism sound tritheistic, then attacks the tritheistic version.
Boyd dedicates considerable space to this in Oneness Pentecostals and the Trinity, noting that Oneness apologists consistently argue against a definition of "person" that Trinitarian theology has never officially held. As Geisler would frame it: this is an attack on a straw man, not on Trinitarianism itself.
Selective Use of New Testament Evidence
In his survey of New Testament monotheism, Bernard quotes 1 Corinthians 8:6 - But to us there is but one God, the Father.
He uses this verse to identify God exclusively with the Father. But he truncates the verse. The full text reads:
- Yet for us there is but one God, the Father, from whom all things came and for whom we live; and there is but one Lord, Jesus Christ, through whom all things came and through whom we live.
Paul's structure parallels the Shema and distributes the divine identity between Father and Son. If 1 Corinthians 8:6 proves that God is the Father and only the Father, it simultaneously equally proves that Jesus is "one Lord" in a way that shares in that divine identity — which is precisely the Trinitarian claim. Bernard cannot have it both ways. This is an inconsistent application of hermeneutical principles — using a text to prove one point while ignoring its immediate context that proves the opposite.
The Anecdote as Theological Evidence
Bernard includes an anecdote about attempting to purchase tefillin (phylacteries) in Jerusalem, where an Orthodox Jewish merchant accepted his money after he quoted Deuteronomy 6:4 with "total adherence." Bernard presents this as evidence validating the Oneness position.
This is a fallacious appeal to anecdotal authority. The merchant's approval proves nothing about the correct interpretation of the Shema. The merchant presumably also rejects the Resurrection, the Virgin Birth, and the divinity of Christ in any form — positions Bernard emphatically holds. The anecdote is rhetorically effective but logically worthless as theological evidence.
The Category Error in God's Nature
Bernard defines God as "a Spirit" (John 4:24) and then uses this to argue that God cannot have multiple persons because spirits are by definition immaterial and non-composite. This is a category error. The claim that God is Spirit tells us something about the mode of God's existence (non-physical, non-corporeal) but says nothing whatsoever about whether the divine being can have internal personal distinctions.
The argument assumes what it needs to prove: that a Spirit being cannot have personal distinctions. Bernard asserts this but never argues for it. It is pure ipse dixit — "because I say so."
he Historical Argument: Selective and Circular
Bernard's strategy throughout the book is to argue that:
- The early post-apostolic church taught Oneness.
- Trinitarianism was a later development corrupted by Greek philosophy.
- Therefore, Oneness represents the original apostolic faith.
This argument has multiple problems:
- It commits the genetic fallacy: the origin of a doctrine does not determine its truth or falsehood.
- The historical claim is simply false. Boyd documents extensively that even pre-Nicene writers like Justin Martyr, Irenaeus, Origen, and Tertullian affirm a real distinction between Father, Son, and Holy Spirit — well before Nicaea.
- Bernard cherry-picks modalist figures (Noetus, Praxeas, Sabellius) while ignoring that these were condemned as heretics by the very communities Bernard claims were Oneness.
- Tertullian coined the Latin term Trinitas precisely in response to Praxeas' modalism — meaning the Trinitarian formulation predates Nicaea as a response to the Oneness position, not the other way around.
The Methodological Flaw Running Throughout
Bernard's deepest methodological error is his failure to distinguish what the Bible emphasizes from what the Bible teaches. The Old Testament emphasizes divine unity because its primary polemical target is polytheism. This is correct and important. But emphasis is not the same as exhaustive definition. The Old Testament also contains:
- The Word of God as a distinct agent (Psalm 33:6; John 1:1)
- The Wisdom of God personified (Proverbs 8)
- The Angel of the LORD who is simultaneously distinguished from YHWH and identified as YHWH (Genesis 16:7–13; 22:11–18; Exodus 3:2–6)
- The Spirit of God as a distinct personal presence (Isaiah 63:10–11)
Bernard's interpretive framework has no way to account for this data except by flattening it into allegory or metaphor — a move he makes without exegetical justification.
Grudem makes the essential methodological point (Systematic Theology, p. 226): the doctrine of the Trinity was not invented by the church; it was discovered as the only coherent framework that could account for all the biblical data — both the emphatic monotheism of the Shema and the New Testament's equally emphatic identification of Jesus and the Spirit with the divine identity. Modalism accounts for the monotheism while destroying the Christology. Trinitarianism accounts for both.

Recommended Rebuttal Strategy
When engaging Message believers using Bernard's framework, the most productive points of attack are:
- Force the Matthew 3:16-17 question: Ask how three simultaneous presences can be modes of one person. Do not let them dodge to "human/divine natures" without pointing out that creates Nestorianism.
- The echad vs. yachid distinction: This is simple, devastating, and difficult to dismiss. The Hebrew God chose supports compound unity, not absolute singularity.
- The full text of 1 Corinthians 8:6: Paul re-reads the Shema distributively between Father and Son. If this verse proves the Father is "one God," the same verse proves Jesus shares in that one divine identity.
- Ask who Jesus was praying to in John 17: If modalism is true, what exactly is happening in that prayer? Make them answer this concretely.
- The Sabellius problem: Bernard identifies his view with historical modalism then acts surprised when it gets called heresy. Point out that Sabellius was condemned as a heretic by the very church Bernard claims originally held Oneness views — meaning Bernard's own historical argument refutes itself.
Boyd's Oneness Pentecostals and the Trinity remains the definitive scholarly response to these arguments and should be consulted for the full exegetical engagement with each major Oneness proof text.
