The Holy Spirit

What is this concept?

This is a Christology site, and the Spirit is not a Christological question. But the doctrine of the Trinity has three legs, and a site that examines two of them and passes over the third leaves the reader with an incomplete picture of what is actually being claimed. Whatever you conclude about Jesus, you still have to say something about the Spirit — and the arguments used to establish the Spirit's personhood and deity are not the same arguments used for Christ's.

The question is straightforward to state. When Scripture speaks of "the Holy Spirit," is it naming a third divine person, distinct from the Father and the Son and equal to them — or is it naming God's own presence, breath, mind and active power, reaching into the world and into people?

Both readings have to account for the same data: language that sounds unmistakably personal (the Spirit teaches, testifies, can be grieved, can be lied to, intercedes), and language that sounds unmistakably like an impersonal power (the Spirit is poured out, given in measure, comes upon people, fills them, can be received in portions).

Where does it come from?

The Hebrew word is ruach (רוּחַ) — breath, wind, spirit. It is a feminine noun with a wide semantic range, and the range is not a problem to be solved: the same word covers a storm wind, the breath in a person's nostrils, and God's animating power over creation. The Greek equivalent, pneuma (πνεῦμα), carries the same span and is grammatically neuter.

Translators face the ambiguity from the very first occurrence. In Genesis 1:2, ruach elohim hovers over the waters. Most English versions read "the Spirit of God"; the NRSV reads "a wind from God"; others have "a mighty wind" or "the breath of God." None of these is a mistake — the Hebrew genuinely admits them, and the choice is made on grounds outside the sentence itself.

What is striking about the Hebrew Bible is how little it says about the Spirit as an independent subject. The exact phrase "holy spirit" appears in only two passages in the entire Old Testament — Psalm 51:11 and Isaiah 63:10–11 — and in both, it is possessive: your holy spirit, his holy spirit. The Spirit belongs to God in the way a person's breath belongs to them. Nowhere in the Hebrew Bible is the Spirit addressed, prayed to, or spoken of as a distinct party alongside God.

The grammatical argument — and why leading Trinitarian scholars have abandoned it

The most widely repeated argument for the Spirit's personhood is grammatical. It runs like this: pneuma is neuter, so we would expect neuter pronouns. But in John's farewell discourse, the masculine demonstrative ekeinos ("that one," "he") appears — at John 14:26, 15:26 and 16:13–14. John, on this reading, deliberately breaks the rules of concord to signal that the Spirit is a person and not a thing.

This argument appears in a long line of respected works — A. T. Robertson's Grammar, the International Standard Bible Encyclopedia, Berkhof's Systematic Theology, and countless sermons and study Bibles since.

It is also, by the assessment of the field's own leading Trinitarian grammarians, invalid. The reason is simple once the sentences are laid out: in every one of these passages pneuma stands in apposition to the masculine noun paraklētos ("Paraclete," "Helper," "Advocate"), and it is paraklētos that the masculine pronoun agrees with. Daniel B. Wallace, whose Greek Grammar Beyond the Basics is the standard intermediate grammar in evangelical seminaries, states it directly:

"But this is erroneous. In all these Johannine passages, pneuma is appositional to a masculine noun. The gender of ekeinos thus has nothing to do with the natural gender of pneuma. The antecedent of ekeinos, in each case, is paraklētos, not pneuma… Although one might argue that the Spirit's personality is in view in these passages, the view must be based on the nature of a paraklētos and the things said about the Comforter, not on any supposed grammatical subtleties."

— Daniel B. Wallace, Greek Grammar Beyond the Basics (Zondervan, 1996), 331–32

Wallace goes further in his journal treatment of the question: "There is no text in the NT that clearly or even probably affirms the personality of the Holy Spirit through the route of Greek grammar. The basis for this doctrine must be on other grounds" ("Greek Grammar and the Personality of the Holy Spirit," Bulletin for Biblical Research 13 (2003): 97–125).

The most thorough treatment is by two Trinitarian scholars, Andrew Naselli and Philip Gons, who survey the argument's history across more than a century of commentaries and grammars and conclude that it is a case of "arguing for the right thing the wrong way." Their verdict on the argument itself is blunt: "The common argument is invalid because the antecedent of the masculine ἐκεῖνος is not the neuter πνεῦμα but the masculine παράκλητος." They record that Grant Osborne, hearing the paper presented at the Evangelical Theological Society, remarked afterwards that the view was more persuasive than the one he had published. Andreas Köstenberger — cited elsewhere on this site as a Trinitarian authority on John — reaches the same conclusion in his commentary (see Naselli and Gons, "Prooftexting the Personality of the Holy Spirit," Detroit Baptist Seminary Journal 16 (2011): 65–89).

The personification problem

With the grammar removed, the weight falls on the personal descriptions. The Spirit teaches (John 14:26), speaks (John 16:13), can be grieved (Eph 4:30), outraged (Heb 10:29), blasphemed (Matt 12:32), lied to (Acts 5:3), and intercedes (Rom 8:26).

The Unitarian reply is not that this language is trivial, but that Scripture uses exactly this register for things no one treats as persons. Wisdom builds a house, sends out servants and calls from the heights (Prov 9:1–3). Sin is "crouching at the door" and "desires" to have Cain (Gen 4:7). Abel's blood "cries out" from the ground (Gen 4:10). Scripture itself "foresaw" and "preached the gospel beforehand to Abraham" (Gal 3:8). Death and Hades ride out on a pale horse (Rev 6:8).

Nearer to the point, the Bible speaks of a person's own spirit in precisely the terms used of God's. David "would not grieve the spirit of Amnon his son" (2 Sam 13:21); "the spirit of the king longed to go out to Absalom" (2 Sam 13:39); "the spirit of Elijah rests on Elisha" (2 Kgs 2:15). No one supposes a second Amnon, a second king, or a second Elijah. And John contrasts "the spirit of truth" with "the spirit of error" in a single sentence (1 John 4:6) — where no translator capitalises the second, because no one posits a person of Error.

Paul's most sustained reflection makes the parallel explicit: "who among men knows the thoughts of a man except the spirit of the man which is in him? Even so, the thoughts of God no one knows except the Spirit of God" (1 Cor 2:11). The analogy is between a person's own inner self-knowledge and God's. On the Unitarian reading, that is what the Spirit is: God's own mind and self-knowledge, not another mind beside his.

The consistency question this raises is genuine. Every interpreter grants that Scripture personifies. The question is what licenses treating the Spirit's personification as literal predication while treating Wisdom's, Sin's, and Scripture's as figures of speech. It is not enough to point at the personal verbs, because the personal verbs are shared. Something else has to be doing the work.

Trinitarians answer that something else is doing the work, and name it: the cumulative pattern. Wisdom is never sent by the Father in the Son's name; Sin is never blasphemed against with eternal consequence; Scripture is never grouped with the Father and the Son in a baptismal formula (Matt 28:19) or a benediction (2 Cor 13:14). The Spirit's personal language is denser, more varied, and embedded in triadic structures that the other cases lack. Whether that difference is one of degree or of kind is the live question.

A test that does not transfer: the HANDS argument

One of the most widely used contemporary cases for the deity of Christ is the HANDS framework of Robert Bowman and J. Ed Komoszewski, in Putting Jesus in His Place: The Case for the Deity of Christ (Kregel, 2007). The acronym organises five lines of evidence: Jesus shares the Honors due to God, the Attributes of God, the Names of God, the Deeds of God, and the Seat of God's throne.

Whatever one makes of that case for Christ — and this site examines the underlying texts passage by passage — there is an observation worth making about its reach. Bowman and Komoszewski wrote about Jesus, and it would be unfair to fault them for not writing about the Spirit. But the framework is regularly presented as the shape a biblical case for deity should take, and applied to the Spirit, four of the five categories return very little:

• Honors. The New Testament records worship of the Father and of the Lamb. There is no scene in which the Spirit is worshipped, no doxology addressed to the Spirit, no prayer directed to the Spirit.
• Names. The Father is YHWH; the Son is given "the name above every name." The Spirit is described by function — Helper, Advocate, Spirit of truth — but is never given a personal name.
• Seat. The Son sits at the right hand of the Majesty; the Father sits on the throne. Revelation's throne room, which is the New Testament's most detailed picture of heavenly worship, seats two parties and not three.
• Greetings. Not part of the acronym, but telling in the same way: every Pauline letter opens with grace and peace "from God our Father and the Lord Jesus Christ." The Spirit sends no greeting in any New Testament letter.

Only Deeds returns a full result: the Spirit does what God does — creates, gives life, speaks through prophets, searches the depths of God. Which is exactly what a Unitarian reading predicts, since on that reading the Spirit's deeds simply are God's deeds.

This is an argument from silence, and arguments from silence are weak in proportion to how much noise we should expect. Trinitarians reasonably reply that the Spirit's characteristic role is to glorify the Son rather than to draw attention to himself (John 16:14) — so a relative absence of Spirit-directed devotion is what the doctrine itself would lead you to expect. That reply has real force. It is also, on its own terms, an explanation of the silence rather than evidence against it.

Why does it matter for the debate?

Because the historical record of how the doctrine was settled is unusually well documented — and unusually late.

The Nicene Creed of 325 devotes long, carefully fought clauses to the Son: begotten of the Father, only-begotten, of the substance of the Father, God of God, Light of Light, true God of true God, begotten not made, of one substance with the Father. On the Spirit, it says, in full: "And in the Holy Spirit." Then the anathemas begin. Whatever the bishops at Nicaea were arguing about, the status of the Spirit was not it.

The Spirit's deity became a live controversy only in the 350s and after, against a group its opponents called the Pneumatomachi — "Spirit-fighters" — who accepted the Son's deity but regarded the Spirit as a creature or a ministering power. Athanasius's Letters to Serapion (c. 357–358) are the first sustained argument on the question. Basil of Caesarea's On the Holy Spirit (375) is the most influential — and Basil argues throughout for the Spirit's equality of honour (isotimia) while conspicuously declining to make the bare statement "the Spirit is God." Gregory of Nazianzus records the criticism this drew at the time: that Basil spoke of the Father and Son magnificently, but "slurred over the Spirit."

Gregory's own testimony, in the Fifth Theological Oration delivered around 380, is the single most striking piece of evidence about where the question stood on the eve of the Council of Constantinople:

"Of the wise men amongst ourselves, some have conceived of him as an Activity, some as a Creature, some as God; and some have been uncertain which to call him."

— Gregory of Nazianzus, Oration 31.5

"The wise men amongst ourselves" are not heretics. They are Gregory's own orthodox colleagues, and in 380 they were divided three ways on whether the Spirit was an activity, a creature, or God.

Gregory's solution is equally significant, because it concedes the scriptural point openly and then argues past it:

"The Old Testament proclaimed the Father openly, and the Son more obscurely. The New manifested the Son, and suggested the Deity of the Spirit."

— Gregory of Nazianzus, Oration 31.26

This is a doctrine of progressive disclosure, offered precisely because the texts do not say plainly what the doctrine requires. It is an honest and coherent theological move — and it is the opposite of the popular claim that the Spirit's personal deity is evident on the face of Scripture. One of the doctrine's principal architects says the Old Testament does not proclaim it and the New Testament only "suggests" it.

This bears directly on a habit worth naming. Because the fourth- and fifth-century categories are so familiar, they are easily read back into texts written centuries earlier. "The Spirit of God" in Genesis 1:2 becomes the third person of the Trinity hovering over the waters; the plural of Genesis 1:26 becomes an intra-Trinitarian conversation; Isaiah's threefold "Holy, holy, holy" becomes a hint at three persons. Gregory, who had every motive to find those readings, did not claim them. See Anachronistic Reading for why this pattern matters across the whole debate.

What do the different traditions say?

Trinitarian: The Holy Spirit is the third person of the Trinity, co-equal and co-eternal with the Father and the Son. The case does not rest on grammar — the best Trinitarian grammarians have said so plainly — but on the convergence of several lines. The Spirit is called a paraklētos, a role only a person can fill, and is promised as "another" Paraclete alongside Jesus, implying one of the same kind. The Spirit does what only persons do: teaches, guides, decides ("it seemed good to the Holy Spirit and to us," Acts 15:28), distributes gifts "as he wills" (1 Cor 12:11). Lying to the Holy Spirit is lying to God (Acts 5:3–4). And the triadic formulae — the baptismal command, the apostolic benediction — place the Spirit alongside the Father and the Son in a way no personification is placed. The lateness of the formal definition proves nothing about the truth of the doctrine: the church defines what it must, when it must, and the Spirit's deity was defined when it was denied. Basil, Athanasius, and the Cappadocians made the case from Scripture, not against it.

Biblical Unitarian: The Holy Spirit is God's own presence, breath, mind and power — not a person distinct from him. The Old Testament, which is where the vocabulary comes from, gives no hint of a third party, and its two "holy spirit" passages are both possessive. Personification is ordinary biblical idiom and is used of Wisdom, Sin, Death, Scripture, and of individual human beings' own spirits, none of which anyone hypostatises. The grammatical argument, long the first line of defence, has been abandoned by Trinitarian grammarians themselves. On Acts 5:3–4, the parallel is agency, not identity: rejecting an apostle is rejecting "the God who gives his Holy Spirit to you" (1 Thess 4:8), just as Israel's grumbling against Moses and Aaron was "not against us but against the LORD" (Exod 16:8). On the Paraclete: Jesus tells his disciples plainly that in this discourse he has been "speaking in figures of speech" (John 16:25), promises "I will come to you" (John 14:18), and the only other use of paraklētos in the New Testament is of Jesus himself (1 John 2:1, usually rendered "Advocate," which obscures the connection). Anthony Buzzard, Kegan Chandler (The God of Jesus in Light of Christian Dogma) and Patrick Navas (Divine Truth or Human Tradition?) develop these lines at length. Jason BeDuhn (Truth in Translation) argues that rendering the neuter relative pronoun as "who" rather than "which" at Acts 5:32 is "a kind of special pleading" that cannot be justified linguistically.

Logos Christology: Pre-Nicene writers who worked with a derivatively divine Logos generally gave the Spirit a third and lower place in the same descending order. Justin Martyr ranks the Spirit third; Origen, in De Principiis, treats the Spirit as genuinely divine yet ordered after the Son and, on some readings, brought into being through him. On this framework the Spirit is real, divine, and personal — but by derivation and in a graded hierarchy, not by co-equality. That is why the fourth-century argument was so difficult: the Nicene party had to convert an inherited hierarchy into an equality, and the Spirit was the last and hardest step. Logos theology has no particular problem with the Spirit being described in impersonal terms in some passages and personal terms in others, because a derived divine agent can be spoken of either way.

Modalism: "Holy Spirit" is one of the modes or manifestations of the one God, not a third person. Oneness writers point out that the Spirit is called both "the Spirit of God" and "the Spirit of Christ" (Rom 8:9) in the same breath, which they read as identifying rather than distinguishing. Jesus's promise that "I will come to you" and his statement that the Spirit of truth "dwells with you and will be in you" describe the same arrival. David K. Bernard (The Oneness of God) argues that the Spirit is simply God himself at work — the one God as he acts, indwells and empowers — and that positing a third person creates the very difficulty the Trinitarian then has to solve. Modalists and Biblical Unitarians largely agree in rejecting a third divine person, while disagreeing sharply about the Son.
